SUMMARY:BIST Open Seminar: Roberta Croce
DESCRIPTION:Natural Strategies for Solar Light Harvesting\nProfessor of Biophysics\, Photosynthesis and Energy at Department of Physics of the Vrije Universiteit in Amsterdam. \nIn this presentation I will introduce the fundamental processes of light harvesting in photosynthetic organisms and discuss their remarkable abilities to adapt and acclimate to diverse light conditions. Photosynthetic organisms have evolved sophisticated strategies to capture and utilize solar energy efficiently\, allowing them to thrive in various environments. This presentation will delve into the mechanisms by which these organisms optimize their light-harvesting capabilities\, including pigment choice\, photoprotection\, and dynamic responses to changes in light quality and quantity.\nThe presentation will discuss key aspects of light harvesting\, such as the spectral tuning of pigments to match available light wavelengths and the regulation of energy flow to prevent damage caused by excess light. Additionally\, the remarkable acclimation abilities of photosynthetic organisms to gradual changes in light intensity will be explored\, highlighting their capacity to fine-tune their photosynthetic machinery for optimal performance under varying light conditions.\nBy examining the natural strategies employed by photosynthetic organisms\, this presentation aims to provide insights into the principles of solar light harvesting. Understanding these natural strategies offers valuable lessons for optimizing light-harvesting systems and harnessing solar energy in a sustainable and efficient manner. \n\nRoberta Croce studied chemistry at the University of Padova and completed her Ph.D. in Plant Biology/Biophysics at the University of Milano in 1998.

SUMMARY:IBEC Seminar: Amnon Buxboim
DESCRIPTION:How does ageing-related stiffening of brain tissue microenvironments affect the regenerative capacity of cns progenitor cells\nProfessor of biology and bioengineering\, the Hebrew University of Jerusalem\, Israel. \nAgeing-related stiffening of neuronal microenvironments in the brain generates potent signals that attenuate the regenerative capacity of oligodendrocyte progenitor cells (OPCs) to proliferate and differentiate. We find that ageing drives substantial remolding of the nuclear lamina in OPCs\, in which A-type lamin levels increase and B-type lamin expression decreases. Owing to the ubiquitous role of lamins in anchoring mostly heterochromatic sections at the nuclear envelope known as lamina associated domains (LAD’s)\, we hypothesized that ageing effects are mediated via altered genomic organization and regulation. In this study\, we isolate OPCs from neonate and aged rats and study the effects of ageing-related tissue stiffening by designing and optimizing hydrogel-based matrices that mimic the extracellular elasticity and adhesion signals of neonate and aged microenvironments. Indeed\, the differences in cellular morphologies and lamina compositions between neonate and aged cells are recapitulated by matrix elasticity. To characterize differences in the structural organization of the nuclear lamina\, we combine high-resolution optical and electron microscopies and perform micropipette aspiration based rheology to define the viscoelastic properties of OPC nuclei within intact cells. LAD mapping is performed using optimized CUT&RUN assays that target endogenous lamin-B1\, thus avoiding the effects of ectopic expression of nuclear envelope proteins\, which is a prerequisite by standard methodologies. Downstream effects on transcriptional regulation are studied via single-cell RNA sequencing (scRNA-seq)\, thus providing insight into cell-to-cell variations. In summary\, our work-in-progress highlights the mechanobiological component of ageing on progenitor cells of the CNS that can stimulate potential therapeutic strategies. \n\nDr. Amnon Buxboim is a professor of biology and bioengineering\, the Hebrew University of Jerusalem\, Israel. Trained as a biophysicist\, he opened the Buxboim Lab for Mechanobiology in 2013. Dr. Buxboim research aims at understanding how physical and mechanical inputs combine with parallel signaling pathways to direct cell-fate decision-making processes. The Buxboim Lab studies oocyte maturation\, preimplantation embryo development\, stromal bone marrow immunomodulation\, and CNS stem/progenitor cell ageing. Dr. Buxboim also studies mechanisms of nuclear mechanotransduction\, as mediated via nuclear lamins and associated nuclear envelope proteins. The Buxboim Lab combines established assays\, advanced computational tools\, newly designed device-based technologies\, and integrates single-cell level genomics with micro-rheological measurements. Based on his research findings\, Dr. Buxboim develops assisted reproductive technologies to advance and improve medical care.

SUMMARY:IBEC Seminar: Magali Suzanne
DESCRIPTION:Mechanical impact of cell delamination on tissue dynamics\, in developmental and tumoral contexts\nCentre de Biologie Intégrative\, CNRS/UMR 5088\, Université Toulouse III\, Toulouse\, France \nHow mechanical forces drive morphogenesis is a fundamental question in the field of biomechanics. Combining imaging\, genetics\, biophysical and modeling approaches\, we found that apoptotic cells\, far from being eliminated passively\, exert a force before dying and thus actively participate in tissue remodeling. This transient force\, generated in the depth of the epithelium\, constitute a mechanical signal involved in tissue folding. Comparing apoptotic cell dynamics to cells undergoing EMT\, we found that a very similar apico-basal force is generated at the onset of EMT.\nWe further deciphered how these forces are transmitted at the tissue scale through the characterization of a specific mechanical state favoring directional force transmission and developed a new method that offers the opportunity to extract automatically\, in strongly deformed epithelia\, a precise characterization of the spatial organization of a given cytoskeletal network combined to morphological quantifications in highly remodeled 3D epithelial tissues.\nIn parallel\, we turned to cancer mechanics\, focusing particularly in tumor progression. Cancer is a largely widespread pathology that corresponds to an overproliferation of cells that could finally invade others tissues. Tumors develop through three increasingly aggressive steps: (1) hyperplasia\, which corresponds to cells overproliferation; (2) dysplasia\, during which cells can acquire a more mesenchymal phenotype\, and finally (3) metastasis. Tumor development can be influenced by mutations but also by external factors\, such as extracellular matrix rigidity. However\, a comprehensive understanding of the intrinsic factors driving tumor evolution is still lacking. Our recent unpublished work identifies unexpected factors that could influence tumor development\, and more specifically the hyperplasia/dysplasia transition\, a critical step in tumor aggressiveness. This work highlights puzzling differences between developmental and tumoral mechanics.

SUMMARY:PhD Thesis Defence: Nimesh Ramesh Chahare
DESCRIPTION:Mechanics of Epithelial tissue subjected to controlled pressure\n\n\n\n\nAuthor: Nimesh Ramesh Chahare\, Integrative Cell and Tissue Dynamics group\n\n\n\nBiography: \nNimesh Ramesh Chahare earned his bachelor’s degree in Mechanical Engineering from the National Institute of Technology\, Nagpur in 2014. He further pursued a master’s degree at the Indian Institute of Science\, Bengaluru\, completing it in 2016. In 2017\, he began his doctoral work in Barcelona\, under the guidance of Prof. Marino Arroyo at Universitat Politècnica de Catalunya\, and Prof. Xavier Trepat at the Institute of Bioengineering of Catalonia. Currently\, he is a PhD candidate in applied mathematics\, specializing in the study of the mechanics of epithelial tissue under controlled pressure. \nAbstract: \nEpithelial sheets form specialized 3D structures suited to their physiological roles\, such as branched alveoli in the lungs\, tubes in the kidney\, and villi in the intestine. To generate and maintain these structures\, epithelia must undergo complex 3D deformations across length and time scales. How epithelial shape arises from active stresses\, viscoelasticity\, and luminal pressure remains poorly understood. To address this question\, we developed a microfluidic chip and a computational framework to engineer 3D epithelial tissues with controlled shape and pressure. In the setup\, an epithelial monolayer is grown on a porous surface with circular low adhesion zones. On applying hydrostatic pressure\, the monolayer delaminates into a spherical cap from the circular zone. This simple shape allows us to calculate epithelial tension using Laplace’s law. Through this approach\, we subject the monolayer to a range of lumen pressures at different rates and hence probe the relation between strain and tension in different regimes while computationally tracking actin dynamics and their mechanical effect at the tissue scale. Slow pressure changes relative to the actin dynamics allow the tissue to accommodate large strain variations. However\, under sudden pressure reductions\, the tissue develops buckling patterns and folds with different degrees of symmetry-breaking to store excess tissue area. These insights allow us to pattern epithelial folds through rationally directed buckling. Our study establishes a new approach for engineering epithelial morphogenetic events. \n  \n\n\nReading date: 20/06/2023\nReading time: 15:00 \nReading place: Facultat de Matemàtiques i Estadística-Sala d’Actes FME\, Edifici U\, Campus Sud\nThesis director: ARROYO BALAGUER\, MARINO and TREPAT GUIXER\, XAVIER\nCommittee:\nPRESIDENT: TRIVEDI\, VIKAS\nSECRETARI: MUÑOZ ROMERO\, JOSE JAVIER\nVOCAL: SUZANNE\, MAGALI \n\n\n

SUMMARY:PhD Discussion: Isabela Fortunato y Marina Martinez
DESCRIPTION:Cell migration up and down fibronectin gradients\nIsabela Fortunato\, Integrative cell and tissue dynamics group \nThe ability of cells to perform directed migration is essential for biological processes\, such as tissue morphogenesis\, immune function\, and cancer invasion. Directed cell migration is often triggered by spatial gradients in the cellular environment (e.g.\, chemical gradients\, called chemotaxis\, substrate stiffness gradients\, called durotaxis\, or substrate-bound ligand gradients\, called haptotaxis). Haptotaxis has been described in vivo as an important phenomenon during physiological and pathological conditions. However\, the molecular and mechanical processes that drive this form of directed cell migration remain elusive. Moreover\, generating accurate and reliable gradients of immobilized protein in vitro has been challenging and makes it harder to study haptotaxis. Here\, we explore how cells sense and respond to gradients of immobilized proteins. We used a photopatterning technique to create well-controlled fibronectin gradients and we studied the migration of single mammary epithelial cells (MCF-10A). This approach allowed us to map cell migration velocity\, traction forces\, and actin cytoskeleton dynamics as a function of fibronectin density. We observed that cells respond to fibronectin gradients by an initial polarization towards higher protein density in the first hours of migration. Surprisingly\, after the initial polarization\, cells maintained their directionality even if they were submitted to a negative protein gradient. This suggests that cells adapt their polarity features to maintain the preexisting structures and organelles geometry towards low fibronectin regions until a limitation on creating new adhesions. In this work we find that one key adaptation mechanism is driven by the actin flows\, specifically the increase in actin polymerization velocity at the leading edge. Besides haptotaxis\, we foresee that these results will shed light on other forms of directed cell migration in which cells integrate several internal and external cues to orient themselves in physiological and pathological processes. \n\nLiving myocardial slices as a representative in vitro platform for translational cardiovascular disease\nMarina Martínez\, Biomaterials for Regenerative Therapies group \nCardiovascular diseases are the leading cause of global mortality\, accounting for nearly 45% of all deaths in Europe. Myocardial infarction (MI) is a prevalent condition\, where a region of the cardiac muscle undergoes ischemia and up to one billion cardiomyocytes die in just a few hours. The heart has a limited regenerative ability; consequently\, cardiomyocytes lost due to MI cannot be replaced. In this scenario\, researchers have investigated and developed alternative therapies to promote cardiac repair and regeneration. \nLactate\, an important metabolite during cardiogenesis and cardiac development\, has been recently described as a potential modulator of the phenotype of cardiac cells in vitro. These findings support a novel use of lactate for endogenous heart regeneration strategies. Nevertheless\, effectiveness of ongoing therapeutic approaches is dependent on the level of maturation of cardiac tissue. Hitherto\, the regenerative capabilities of lactate in mature cardiac tissue have not been described. In this work\, we used living myocardial slices (LMS) as a model of mature cardiac tissue. LMS are 300 μm-thick slices of living myocardium with conserved physiological structure and function. Human and rat adult LMS were treated with lactate to evaluate early cellular\, molecular\, and functionality changes related to myocardial reprogramming\, cardiac structural rearrangements\, and fibrosis. Moreover\, the effect of lactate was characterized in both healthy and injured adult myocardium. \nFunctionally\, (8 mM) lactate-treated healthy and pathological human LMS displayed an increase in contractility. Expression of fibrotic\, pluripotency transcription factors\, and cardiomyocyte markers were detected. Exposure of healthy rat LMS to higher concentrations of lactate (20 mM) did not affect LMS viability nor altered LMS contractile force\, while promoted LMS stiffening. In cryoinjured rat LMS\, lactate drastically increased contractility and altered tissue remodeling in the region bordering the injury. \nLMS provide a representative in vitro platform for translational cardiovascular research. By using LMS\, characterization of the effect of lactate in mature cardiac tissue has been achieved. Exogenous lactate enhanced cardiac function in both human and injured rat LMS. Upregulation of transcription factors and cardiomyocyte markers may suggest an effect on partial cardiomyocyte reprogramming that would counteract the effects of tissue stiffening. Altogether\, this study further supports the prospective use of lactate as a bioactive signal in new endogenous cardiac regeneration strategies. \nThis PhD Discussion session will be held at Tower I\, 11th floor Baobab room\, at 10:00am.

SUMMARY:IBEC Seminar: Theodore Alexandrov
DESCRIPTION:Spatial single-cell metabolomics reveals metabolic cell states\nEMBL \nRecent discoveries put metabolism into the spotlight. Metabolism not only fuels cells but also plays key roles in health and disease. In parallel\, emerging single-cell technologies opened a new world of cell types and states previously hidden beneath population averages. Yet\, methods for discovering links between metabolism\, cell states\, metabolic plasticity and reprogramming on the single-cell level and in situ are crucially lacking. Our research aims to contribute bridging this gap. First\, we will present how the emerging technology of imaging mass spectrometry can be used for the spatial profiling of metabolites\, lipids\, and drugs in tissues. These efforts are enabled by our big data community cloud platform METASPACE which is increasingly used across the world. Next\, we will present method SpaceM for spatial single-cell metabolomics. SpaceM detects 100+ metabolites or 500+ lipids from thousands of individual cells together with fluorescence and morpho-spatial features. We used SpaceM to characterize how stimulating human hepatocytes with fatty acids led to the emergence of two co-existing subpopulations outlined by distinct cellular metabolic states. Inducing inflammation with the cytokine IL-17A perturbs the balance of these states in a process dependent on NF-κB signalling. We will show how a high-throughput version of the SpaceM method helps discover and characterize metabolic states of activated CD4+ T cells from peripheral human blood. Finally\, we will present how spatial multi-omics can reveal the relationships between cell types and cell states in tissues. Overall\, such methods can open novel avenues for understanding metabolism in tissues and cell cultures on the single-cell level.

SUMMARY:IBEC Seminar: Loris Rizzello
DESCRIPTION:Towards an evolutionary-driven universal therapy against (intracellular) pathogens\nUniversità degli Studi di Milano \nWe are living a time where we believe antibiotics are the cornerstone of any infectious disease-based therapy. It is definitely out of question that antibiotics saved millions of people worldwide in the last century\, and that they are still doing it very efficiently. Nevertheless\, their extensive abuse\, especially for zoonic applications\, contributed to the rise of antibiotic resistance (AMR). AMR is one of the biggest threats in the current human history because it is estimated that the majority of the antibiotics\, currently used in the clinics\, will be completely ineffective for the eradication of infectious disease. This has been defined as “The New Dark Ages of Antibiotics”\, which is expected to start in the next decades if no actions will be taken now. There are several causes behind AMR\, but one of the most relevant is the exposure of bacteria to sub-lethal doses of the antimicrobials. One of the big aim of our research efforts is to design of a new generation of therapy that counteract this issue. It is inspired on solutions already provided by Nature\, and it is based on the strategy exploited by a specific class of viruses that infect and kill bacteria only\, called as bacteriophages\, which are completely safe and unharmful to humans. The development of a new therapy possessing the requirements to avoid the rise in AMR represents a new legacy for the future generation in terms of anitibacterial therapies\, exaclty in the same way antibiotics changed the human history in the 20th century.

SUMMARY:IBEC Seminar: Zev Gartner
DESCRIPTION:Building tissues to understand how tissues build themselves\nZev Gartner\, UCSF \nCells assemble into tissues and organs through an active process termed self-organization. Harnessing tissue self-organization will ultimately advance applications as diverse as disease modeling and regenerative medicine\, while revealing new strategies for fighting disease. However\, progress towards these applications is limited by our incomplete understanding of how the properties of tissues emerge from their cellular building blocks.  I will discuss two recent projects that aim to address this knowledge gap.  In a first project\, we use human mammary organoids to make the remarkable observation that tissues can behave as dynamic structural ensembles. We model the ensemble using a maximum entropy framework\, and demonstrate the probability distribution of tissue structures is a function of the entropy associated with cell arrangements\, the energy associated with cell interfaces\, and mechanical fluctuations associated with cell motility.  We map these parameters back to measurable molecular and mechanical properties of cells and their microenvironment\, allowing us to engineer the structural ensemble quantitatively and systematically.  In a second project we use the morphogenesis of mouse intestinal villi to reveal that tuning the geometry and active mechanics of the epithelial/mesenchymal interface is sufficient to sculpt a diversity of tissue forms. In the gut\, MMP and Myosin-II dependent fluidization of a contractile and adhesive sub-epithelial mesenchyme results in a dynamic monolayer of cells with a high surface tension. Minimization of surface energy results in a process we call “mesenchymal de-wetting\,”  which results in the formation of an array of multicellular condensates that act to pattern and fold the overlying epithelium. Manipulating the properties of the cells or the interface results in predictable changes to the pattern and shape of the folds. These studies have some important implications for tissue engineering\, disease progression\, and our understanding of tissue self-organization in other contexts.

SUMMARY:IBEC-IFIBYNE Webinar Cycle (online) 12th July 2023 at 16:00 Javier Ramon
DESCRIPTION:Organ on a chip models to emulate multi systemic metabolic diseases\nJavier Ramon\, IBEC \nExisting on-chip tissue models typically represent a single organ\, limiting systemic drug investigations. Microscale tissue analog systems aim to improve drug and toxicity predictions across various organs. However\, multi-organ devices are limited\, and none have explored skeletal muscle and pancreatic islets. We developed a novel multi-organ-on-a-chip platform for real-time\, sensitive monitoring of cross-talk between two organs. Unlike previous electrochemical platforms\, our sensing system offers cost-effectiveness\, label-free detection\, easy integration\, multiplexing\, and real-time monitoring. This platform quantifies secreted proteins with high sensitivity\, crucial for understanding the relationship between skeletal muscle and the pancreas. Our work shows promise for disease modeling\, drug screening\, and personalized medicine. \n\nDoctor Javier Ramon is an ICREA Professor since 2021 and the leader of the Biosensors for Bioengineering group at the Institute of Bioengineering of Catalonia. Javier studied Chemistry at the University of Catalonia and completed his PhD at the CSIC in the Institute of Advanced Chemistry of Catalonia. He conducted his postdoctoral research in Japan at the Advanced Institute of Materials and returned to Spain in 2016 as a Ramon y Cajal researcher. His research is focused on tissue engineering\, biomaterials\, biosensors\, and integrating these technologies into organ-on-chip devices to study diseases and drug screening.

SUMMARY:IBEC Seminar: Dan Vigneron
DESCRIPTION:Translation and Initial Patient and Volunteer Studies with Hyperpolarized Carbon-13 MR Molecular Imaging\nDan Vigneron\, Department of Radiology & Biomedical Imaging\, University of California San Francisco \n“Hyperpolarized (HP) carbon-13 MRI is an emerging molecular imaging method to monitor enzymatic conversions through key\, previously-inaccessible biochemical pathways. Over 1000 human HP carbon-13 MR studies to date have shown outstanding research and potential clinical value. Just as MRI has shown value for medical imaging providing information beyond CT/X-ray\, HP C-13 MRI can provide new isotope imaging biomarker information in addition to what PET & SPECT do. HP C13 MRI is safe\, ~2min\, non-radioactive addition to standard-of-care MRI exams\, at costs less than separate PET exam. At the UCSF Hyperpolarized MRI Technology Resource Center\, we are developing new techniques for rapid dynamic acquisitions to measure HP conversion rates for [1-13C]pyruvate to [1-13C]lactate\, [1-13C]alanine and 13C-bicarbonate in the abdomen\, pelvis\, heart and brain to monitor cellular metabolism in normal tissues and pathologies. We are conducting over 15 clinical trials of HP C-13 MRI and have translated 4 different HP probes into first human studies: [1-13C]pyruvate\, [2-13C]pyruvate\, [1-13C]alpha-ketoglutarate\, and 13C-urea. Initial results demonstrate the ability to detect cancer aggressiveness\, response to therapy\, cardiac disease and brain bioenergetics. \n\nDr. Daniel B. Vigneron Ph.D. is a Professor in the Department of Radiology & Biomedical Imaging and at the University of California\, San Francisco. He also has joint appointments in the Departments of Bioengineering & Therapeutic Sciences and Neurological Surgery at UCSF and is a member of the UCB/UCSF Bioengineering graduate group. He directs the UCSF Human Imaging Core and the Advanced Imaging Technologies Resource Group that facilitates imaging technique development in the Department of Radiology & Biomedical Imaging including: Hyperpolarized Carbon-13\, PET-MR\, and 7T MR. He also is the Director of the NIH NIBIB-funded Hyperpolarized C-13 MRI Technology Resource Center at UCSF that was recently renewed till 2027 with 20 external collaborative and service projects. This UCSF Hyperpolarized MRI Technology Resource Center also sponsors numerous training and education opportunities including symposia/workshops focused on the development and dissemination of new HP-MRI techniques. Dr. Vigneron was elected Fellow of the International Society of Magnetic Resonance in Medicine in 2009 and to the College of Fellows of the American Institute for Medical and Biological Engineering in 2007. He received the Academy of Radiology Research Distinguished Investigator Award in 2013 and with colleagues was awarded the Gold Medal of the World Molecular Imaging Society in 2014. \nDr. Vigneron obtained his BA in Chemistry from Wesleyan University in Middletown\, Connecticut in 1983\, and he completed his PhD research in Pharmaceutical Chemistry from UCSF in 1988 and then conducted post-doctoral research at the Fox Chase Cancer Center in Philadelphia and at UCSF developing new MRI techniques for characterizing disease and therapy response.

SUMMARY:PhD Thesis Defense: Sefora Conti
DESCRIPTION:Mechanical phenotyping of cancer stemness in colorectal cancer.\n\n\n\n\nAuthor: Sefora Conti\, Integrative cell and Tissue Dynamics group\n\n\nReading date: 18/07/2023\nReading time: 15:00 \n\nAbstract: Colorectal cancer tumors are composed of heterogeneous and plastic cell populations\, including a pool of cancer stem cells that express LGR5. Whether these distinct cell populations display different mechanical properties\, and how these properties might contribute to metastasis is unknown. Using CRC patient derived organoids (PDOs)\, we found that compared to LGR5- cells\, LGR5+ cancer stem cells are stiffer\, adhere better to the extracellular matrix (ECM)\, move slower both as single cells and clusters\, display higher nuclear YAP\, show a higher survival rate in response to mechanical confinement\, and form larger transendothelial gaps. These differences are largely explained by the downregulation of the membrane to cortex attachment proteins Ezrin/Radixin/Moesin (ERMs) in the LGR5+ cells. By analyzing scRNA-seq expression patterns from a patient cohort\, we show that this downregulation is a robust signature of colorectal tumors. Our results show that LGR5- cells display a mechanically dynamic phenotype suitable for dissemination from the primary tumor whereas LGR5+ cells display a mechanically stable and resilient phenotype suitable for extravasation and metastatic growth. \n  \n\nReading place: Aula Marga\, Hospital Clinic \n\nMore information here.

SUMMARY:IBEC Seminar: MDr Joanna Sierpowska
DESCRIPTION:Awake brain surgery mapping – a way to mitigate postsurgical impairments and a door to understanding human cognition\nMDr Joanna Sierpowska from the Department of Cognition\, Development and Educational Psychology\, Institute of Neurosciences\, University of Barcelona \nBrain mapping for language and cognition during awake brain surgeries helps neurosurgeons to mitigate postsurgical impairments. At the same time\, it uncovers the truth about brain functional organization. While the cortical procedures are very well studied and widely implemented since the ’50 of the XX century confirming the classical models of language production\, the work on mapping the white matter pathways has developed very recently. The dual pathway model for language introduces the importance of the perisylvian white matter in the processing of speech sounds and word meaning. In the present talk\, I will explain if the model was successfully confirmed by intraoperative language testing. Furthermore\, I will explain how we assess language function associated with the model perioperatively in a large sample of brain tumor patients.

SUMMARY:IBEC Seminar: Virgil Percec
DESCRIPTION:Reprogramming the Factory of Life to Target the Delivery of mRNA via Helical Chirality\nVirgil Percec\, Roy & Diana Vagelos Laboratories\, Department of Chemistry\, University of Pennsylvania\, Philadelphia \nHomochiral helical self-organizations are known at the macroscopic level in nature\, art\, architecture and science for thousands of years [1a\,b]. However\, molecular helicity was discovered in proteins and DNA [2] only in the early 1950th and in molecular\, macromolecular and supramolecular complex nanosystems emerged soon after [1c\,d\,e\,f]. Our ability to program functions at the supramolecular level based on helical chirality is less advanced than the same process at the macroscopic level during Archimedes and Leonardo da Vinci times. The principles “discover-elucidate mechanism-predict programmed primary structure” elaborated in our laboratory and aided by synthetic methodologies developed also in our laboratory for accelerated modular-orthogonal synthesis of programmed structures such us Ni-catalyzed cross-coupling\, mixed-ligand\, thio-bromo click\, SET-organic and polymerizarion reactions\, self-accelerated and self-interrupted synthesis including selected examples of homochiral helical self-organizations and functions together with the molecular factory of life will be briefly explained. The origins of helical homochirality is equivalent to the origins of life although the origins and the rational of biological membranes homochirality continues to be debated [3]. Inspiration from amphiphilic Janus dendrimers [4a] and Janus glycodendrimers [4b] discovered in our laboratory allowed to transit from the commercial viral and four-component lipid nanoparticle synthetic vectors for delivery of mRNA to the one-component ionizable multifunctional sequence-defined amphiphilic Janus dendrimers (IAJDs) delivery vector [5]. The current status of the molecular design principles providing the least expensive and the simplest access to targeted delivery of mRNA with programmed IAJDs will be discussed in great details. Targeted delivery of mRNA to all organs is expected to change the field of nanomedicine at the most fundamental level by providing unprecedented avenues to new vaccines and therapeutics. \nReferences \n\n(a) Percec\, V.; Xiao\, Q.

SUMMARY:IBEC Seminar: Dr. Andy Tay
DESCRIPTION:Biomaterials for cancer study and accelerate wound healing\nDr. Andy Tay \, Assistant Professor\, Presidential Young Professor\, Department of Biomedical Engineering \nMagnetic hydrogels are materials containing magnetic microparticles which help transduce magnetic fields into mechanical forces. In the presence of a static magnet\, the stiffness of magnetic hydrogels can be altered to investigate the reversible effects of matrix softening and stiffening on cellular behaviours. Here\, I will describe how we exploit this unique feature of our material for cancer study. \nThe World Health Organization estimates that 10% of the world’s population suffers from diabetes\, and diabetic patients has a 15-25% lifetime risk of getting diabetic foot ulcers. Every 20s\, there is a lower extremity amputation worldwide. In the second half of my talk\, I will describe the use of magnetic hydrogel for mechanical stimulation of cells to synergistically accelerate diabetic wound healing. \n\nAndy Tay graduated in 2014 from NUS with a First-Class Honours in Biomedical Engineering. He later headed to the University of California\, Los Angeles for his PhD studies and graduated in 2017 as the recipient of the Harry M Showman Commencement Award. Andy next received his postdoctoral training at Stanford University before heading to Imperial College London as an 1851 Royal Commission Brunel Research Fellow. He is currently a Presidential Young Professor in NUS. \nAndy is a recipient of international awards including the Interstellar Initiative Early-Career Faculty Award\, Christopher Hewitt Outstanding Young Investigator Award\, Terasaki Young Innovator Award. He is listed as a 2019 Forbes 30 Under 30 (US/Canada\, Science)\, 2020 World Economic Forum Young Scientist\, 2020 The Straits Times ‘30 and Under’ Young Singaporeans to Watch and 2022 Top 2% Scientist in the World by Stanford University. \n

SUMMARY:IBEC Seminar: Simone Reber
DESCRIPTION:Conserved nucleocytoplasmic density homeostasis drives cellular organization across eukaryotes\nSimone Reber\, Max Planck Institut for Infection Biology\, Berlin (invited by Pere Roca-Cusachs) \nThe packing and confinement of macromolecules in the cytoplasm and nucleoplasm has profound implications for cellular biochemistry. How intracellular density distributions vary and affect cellular physiology remains largely unknown. We show that the nucleus is less dense than the cytoplasm and that living systems establish and maintain a constant density ratio between these compartments. Using label-free biophotonics and theory\, we show that nuclear density is set by a pressure balance across the nuclear envelope in vitro\, in vivo and during early development. Nuclear transport establishes a specific nuclear proteome that exerts a colloid osmotic pressure\, which\, assisted by entropic chromatin pressure\, draws water into the nucleus. Using C. elegans\, we show that while nuclear-to-cytoplasmic (N/C) volume ratios change during early development\, the N/C density ratio is robustly maintained. We propose that the maintenance of a constant N/C density ratio is the biophysical driver of one of the oldest tenets of cell biology: the N/C volume ratio. In summary\, this study reveals a previously unidentified homeostatic coupling of macromolecular densities that drives cellular organization.

SUMMARY:Workshop “Bioaction: The new tissue engineering approaches in bone infections"
DESCRIPTION:Workshop held in the framework of the EIC Pathfinder project BIOACTION “Bacteria biofilm as bio-factory for tissue regeneration” (Project Number 101098972). \nBIOACTION aims at developing a new methodology in implant technology based on functionalized bio-hydrogels that will convert the negative occurrence of biofilm-associated infections\, the primary cause of implant infections and failure\, into a positive resource. The main goal of BIOACTION is to transform implant-associated bacteria for the programmable production of specific proteins for in vivo cell recruitment and tissue regeneration\, exploiting gene sequences loaded on engineered liposomes and phages\, bound to hydrogel scaffolds. BIOACTION will develop new biomimetic substrates that can transform biofilm into extracellular matrix for the regeneration of target tissues. It will establish a high versatile technology to be used as injectable materials and implant coatings for periodontal and peri-implant infection treatments. The proposed approach will be validated in two clinically relevant animal models: dental implant and permanent transcutaneous bone. \nBIOACTION\, would radically advance the future of infection treatment by revolutionizing the classical approaches leading to the improvement of state of care\, health outcomes and to achieve huge socio-economic benefits. The project is strongly interdisciplinary in nature involving expertise biomaterials\, synthetic biology\, phage and liposome technology\, medicine. \nAs a results\, this innovative approach will bring the research and knowledge far beyond the current state-of-the-art and will lead\, through the planned validation\, as proof-of-concept of new materials and technique with a broader application in regenerative medicine. \nIn this workshop\, participants from all the institutions involved in the project will explain their research and activities. \n  \nChairs: Elisabeth Engel\, Luigi Ambrosio \n14:30 – Claudia Siverini and Marco Chittò (AO Foundation)\, “Bone infections and treatments” \n14:45 – Dorien Van Hede (Université de Liege)\, “Dental infections and treatments” \n15:00 – Diego Cotella (Università degli Studi del Piemonte Orientale)\, “Phages to control biofilms” \n15:15 – Dr. Cecilia Bombelli (Consiglio Nazionale delle Ricerche – Instituto per i Sistemi biologici)\, “Liposomes in gene therapy” \n15:30 – Ramūnas Valiokas (Ferentis)\, “Crosslinked peptide hydrogels for tissue engineering and modeling” \n15:45 – Giovanna Gomez d’Ayala (Consiglio Nazionale delle Ricerche – Instituto per i Polimeri\, Compositi e Biomateriali)\, “Hydrogels for tissue regeneration” \n16:00 – Oscar Castaño (IBEC)\, “Advanced characterization methodology” \n16:15 – Roberta Marzella (Consiglio Nazionale delle Ricerche – IPCB) and Michela Candotti (IN Society) – “Tips on Management and Dissemination of European Projects” \n16:30 Discussion and conclusions

SUMMARY:IBEC Seminar: Jaap den Toonder
DESCRIPTION:Microfluidic technology enabling biomedical applications\nJaap den Toonder\, Microsystems Research Section\, Department of Mechanical Engineering\, and Institute for Complex Molecular Systems\, Eindhoven University of Technology.  \nCurrently\, visiting professor at IBEC\, Barcelona \nMicrofluidics is the science and technology of manipulating and analyzing fluid flow at small scales\, typically from millimeters down to micrometers. At these scales\, fluid flow is almost always laminar which enables excellent control over the flow. Microfluidic devices can be made using a range of microfabrication approaches and materials\, and these enable to integrate tailored electronic or mechanical functions. These unique properties of microfluidic technologies\, and the ongoing further development of the technology\, enable a range of new biomedical applications\, including diagnostic and monitoring devices\, medical implants\, and organ-on-chip. \nIn this lecture\, I will present recent developments within three research lines of our lab. (1) Bio-inspired microfluidics: A novel microfluidic flow generation concept inspired by nature\, which is based on magnetic nano- and micro-actuators we call “artificial cilia”; integrated in microfluidic devices\, these can be used to induce flow\, to manipulate particles\, and as actuators in cellular mechano-transduction research. (2) Microfluidic devices for health: Examples of microfluidic devices for health applications\, specifically a sweat sensing device for non-invasive semi-continuous monitoring of hospitalized patients\, and a smart eye implant to control eye pressure in glaucoma patients after surgery. (3) Organ-on-chip: A game-changing technology in which human cells are cultured in microfluidic chips simulating and predicting the response of healthy and diseased human tissues. I will focus on cancer-on-chip approaches to understand initial stages of cancer metastasis\, and on our lumen-based organ-on-chip models that are enabled by a 3D sugar printing technique we developed.

SUMMARY:PhD Discussions: Thomas Wilson and Judith Fuentes
DESCRIPTION:Multiscale buckling of epithelial shells\nThomas Wilson\, Integrative Cell and Tissue Dynamics group \nNumerous natural and engineered structures are shaped as thin curved shells. When subjected to excessive compressive loading\, these shells undergo buckling instabilities that result in wrinkling patterns with complex dynamics. Epithelial tissues such as those enclosing embryos or lining glandular organs are a class of thin shells that displays three distinctive mechanical features: they are viscoelastic over the time scales of physiological loading\, they carry an active surface tension\, and their stress-bearing elements are distributed across scales. The conditions under which these material properties enable buckling\, and the subsequent structural changes are not understood. Here we establish the buckling dynamics of epithelial shells of controlled geometry over several orders of magnitude in time and space. We developed an experimental system that allows us to sculpt epithelial shells and subject them to controlled pressure differentials. We show that\, under rapid pressure reductions relative to a characteristic viscoelastic time of the system\, the tissue develops buckling patterns with different degrees of symmetry that depend on its size and shape. By contrast\, slow deflations allow the tissues to accommodate large strain variations without buckling. Strikingly\, we find that epithelial buckling is a multiscale phenomenon involving supracellular folds but also subcellular wrinkles in the actin cortex. Additionally\, we can harness the active viscoelastic behaviour of the cell cortex to pattern epithelial folds by rationally directed buckling. Our study shows that epithelial tissues can be understood as hierarchical materials with mechanical instabilities that can be harnessed to engineer morphogenetic events. \n\nEvaluation of self-healing properties in skeletal muscle-based bioactuators\nJudith Fuentes\, Smart Nano-Bio-Devices group \nThree dimensional bioprinting has opened new possibilities for the bioengineering of skeletal muscle models with organization and functionality similar to native tissues. This is key to understand the physiological conditions of skeletal muscle to integrate some of their unique properties\, such as self-healing\, adaptability\, and response to external stimuli\, in biohybrid systems. However\, the inherent self-healing capability of skeletal muscle has not been fully exploited in these advanced biohybrid platforms. In vivo\, skeletal muscle tissue may be repaired via the regenerative function of satellite cells (SC). However\, in in vitro conditions\, these cells are difficult to expand without altering their self-healing potential. Myogenic reserve cells (RC) offer an alternative potentially useful source to implement advanced regenerative capabilities in biohybrid systems. RC present similar properties to SC and arise during in vitro myoblast differentiation when a subpopulation escape from terminal differentiation. This work presents a 3D-bioprinted skeletal muscle bioactuator which self-healing properties have been evaluated after generating physical damage to the tissue\, either by creating cuts or crush injuries. Further studying over the underlying biological events related to muscle repair will be key to moving forward with the design of muscle-based bioactuators with on-demand assisted self-healing properties.

SUMMARY:IBEC Seminar: Josep Puigmartí-Luis
DESCRIPTION:What can microfluidic technologies offer during self-assembly processes?\nJosep Puigmartí-Luis\, Departament de Ciència dels Materials i Química Física\, Institut de Química Teòrica i Computacional (invited by César Rodriguez-Emmenegger) \nSelf-assembly has long being used to control covalent and non-covalent interactions where molecular design has been the major driving force to achieve a desired outcome. Like in nature\, a full control over self-assembly processes could lead to rationalized structure-property correlations\, a long-time sought in chemistry\, physics and materials science. However\, the pathways followed and the mechanisms underlying the formation of supramolecular aggregates are still a major challenge for the scientific community. Accordingly\, the elucidation of nucleation and growth mechanisms will be highly required to push supramolecular chemistry to the next level\, where access to nature inspired functions will be accomplished. In this contribution\, I will present how reaction-diffusion (RD) conditions established within microfluidic devices can be used to uncover pathway complexity as well as to trigger pathway selection. Specifically\, I will show that microfluidic RD conditions provide an unprecedented kinetic control over self-assembly processes; for example\, enabling the isolation of well-defined kinetically trapped states as well as unprecedented metastable intermediates. This research provides a new tool to study and understand supramolecular chemistry\, and opens up new avenues for the engineering of advanced functional assemblies and systems. \n\nProf. Dr. Josep Puigmartí-Luis is a chemist who completed a master in Chemistry and Food Engineering at “Institut Químico de Serrià (IQS)” (2003) and did a PhD in materials science at Institut de Ciència de Materials de Barcelona (ICMAB). His work in supramolecular and flow chemistry\, has been awarded with “Premi Antoni de Martí i Franquès de Ciències Químiques”\, award from the Institut d’Estudis Catalans (2009)\, St. Jordi award from the Institut d’Estudis Catalans and the Societat Catalana de Química (2006) and an ETH fellowship in 2008. \nIn 2012\, he was appointed a Ramon Y Cajal (RyC) researcher\, but after two years as a RyC\, he decided to move back to Switzerland where in 2015 was awarded an ERC starting grant to study and control self-assembly processes of metal-organic based crystalline materials. In 2019\, he was appointed as an ICREA professor and since August 2020 his group is located at the University of Barcelona (UB).

SUMMARY:IBEC Seminar: Martí Duocastella
DESCRIPTION:Toward the next generation of 3D optical microscopes: faster\, deeper\, and label-free\nMartí Duocastella\, Departament de Fisica Aplicada\, Universitat de Barcelona \nThree-dimensional (3D) optical microscopy is the tool of choice for characterizing the structure and dynamics of biological systems at sub-cellular resolution. However\, most microscope architectures are tailored to capture two-dimensional (2D) information from moderately thin samples labeled with fluorophores. Due to constraints posed by light scattering and the requirement for mechanical focus translation\, existing systems provide shallow penetration depth and low volumetric imaging speed\, thus falling short of unraveling biological complexity inside medium-sized organisms or even organoids. In this talk\, I will discuss our efforts to overcome these issues and achieve sub-millisecond imaging at potentially millimeter depths and without labels. Our strategy consists of focusing\, modulating\, and guiding light by exploiting the acousto-optic effect\, that is\, ultrasound-induced refractive index gradients. The unique interaction between ultrasound and light enables rapid 3D light control\, making it suitable for the development of inertia-free light sheet microscopes that lack mechanically moving parts and offer imaging rates of tens of volumes per second. It also facilitates illumination encoding in single-pixel cameras\, enabling scanless 2D imaging at 5 kHz. Interestingly\, applying ultrasonic waves in a scattering medium acts as an instantaneous waveguide embedded in the medium\, helping to redirect light toward a 7-fold deeper focus. I will discuss the advantages and pitfalls of these acousto-optic technologies and illustrate them with applications\, including imaging of spheroids and flowing samples. \n\nMartí Duocastella is a Serra Hunter full professor in the Department of Applied Physics at Universitat de Barcelona (UB) and leader of the Dynamic Optical Systems Lab. He completed his PhD in Physics at UB in 2010 and then moved to Princeton University as a postdoctoral research associate\, where he also became the vice-president of Research and Development of the startup company TAG Optics. In 2014 he joined Istituto Italiano di Tecnologia as a researcher (group leader)\, until returning to Barcelona as a faculty member in 2019. His research focuses on novel optical methods for three-dimensional (3D) light engineering\, with applications in materials science\, sensing\, and biology. He is an ERC Consolidator Grant awardee. \nIn 2012\, he was appointed a Ramon Y Cajal (RyC) researcher\, but after two years as a RyC\, he decided to move back to Switzerland where in 2015 was awarded an ERC starting grant to study and control self-assembly processes of metal-organic based crystalline materials. In 2019\, he was appointed as an ICREA professor and since August 2020 his group is located at the University of Barcelona (UB)
