SUMMARY:PhD Discussions Sessions: Nimesh Ramesh and Sock Ching Low
DESCRIPTION:Microfluidic device for engineering 3D epithelial monolayers with controlled pressure\nNimesh Ramesh\, Integrative Cell and Tissue Dynamics \nThe remarkable feature of the epithelial sheets is to form specialized 3D structures suited to their physiological roles\, such as highly branched structures in the lungs\, drastic shape changes during embryonic development\, or self-organizing organoids. These tissues are distinctive not just in the forms cells assume\, but also in function. To achieve this\, tissues and the cells in them exhibit coordinated behavior across the spatial and temporal scale. In a sense\, 3D epithelia resemble an active material that adapts and changes in response to its biophysical-chemical stimuli like gene expression\, morphogen gradients\, and lumen pressure. A rheological study of the epithelia would provide unique insight on two fronts. First\, to understand the fundamental physical rules of the biology\, and second for inspiration of new engineering tools and design principles. \nOur study focuses on the tissue response to physical forces\, specifically pressure\, tension\, and curvature. We have fabricated a microfluidic setup to subject epithelial tissues to lumen pressure at different spatial and temporal scales. The epithelial monolayer is grown on a porous surface with circular low adhesion zones. On applying controlled pressure\, the monolayer delaminates into a spherical cap (dome). Laplace law for spherical shells allows us to compute tension in the 3D structure with applied pressure and the radius of the dome. \nThis microfluidic device helps us to characterize the 3D epithelial shape along with the mapping of physical forces. Here\, we demonstrate that the device can subject MDCK epithelial cells to a range of lumen pressure at different rates. Drastic reduction in pressure results in tissue collapsing into wrinkles; showing buckling tendency of the tissue under compression. We think that our device enables studying geometrical and biophysical constraints of tissues and unravel emergent phenomena in tissues. \n\nSaccade rate is associated with number of items in working memory\nSock Shing Low\, Synthetic\, Perceptive\, Emotive and Cognitive Systems (SPECS) \nWorking memory has been shown to rely on theta oscillations for item representations\, and the successful recall of items depends greatly on theta’s phase during both encoding and recall. At the same time\, it has been observed that saccadic eye movements during visual exploration trigger theta phase-resets\, raising the question of whether the neuronal substrates of mnemonic processing rely on motor-evoked responses. To quantify the relationship between saccadic eye movements and working memory load\, we tested human participants performing an n-back Sternberg auditory task in combination with a colour-based catch detection task. We observed a task-specific interference in performance and an increase in saccade rate when both tasks were carried out simultaneously. Saccade rate also increased concurrently with working memory load in the Sternberg task’s pre-response stage\, reflecting its hypothesised role in memory recall. Our results suggest an interplay between saccades and hippocampal theta during retrieval of items in working memory. \nThe PhD discussions session will be held ONLINE at the GoToMeeting platform

SUMMARY:PhD Thesis Defense: Anna Vila Giraut
DESCRIPTION:Hydrogel co-networks of gelatin methacryloyl and poly(ethylene glycol)diacrylate sustain 3D functional in vitro models of intestinal mucosa\nAnna Vila Giraut\, Biomimetic systems for cell engineering Group\nConventional in vitro cell culture models do not possess the complexity that the native tissues offer. Because of this\, the functional properties of the tissues are not properly mimicked\, which causes poorly predictive capabilities. Engineered tissues\, which combine biofabrication and tissue engineering techniques\, try to overcome this gap by providing the cells with an environment similar to the native tissue\, recapitulating (I) the physicochemical and mechanical properties of the cellular matrix\, (II) the multicellular complexity of the different tissue compartments\, and (III) the 3D structures of the tissues. These new engineered models are key factors to improve the platforms for basic research studies\, testing new drugs or modelling diseases. Among all the engineered tissues\, the intestinal mucosa is not well represented. The intestinal mucosa is formed by the epithelium\, which is a multicellular monolayer laying on top of the lamina propria\, a connective tissue containing several cell types (mesenchymal cells\, immune cells). The gold standard intestinal models are based on epithelial cell lines derived from colon cancer cells grown on the hard porous membranes of the Transwell® inserts. The lack of the intestinal stromal compartment and the growth on a hard surface give high transepithelial electrical resistance and low apparent permeability. Therefore\, the development of better in vitro platforms\, which integrates both compartments and provides epithelium-lamina propria cell interactions\, is highly desirable. \nIn this work\, we describe an easy and cost-effective method to engineer a 3D intestinal mucosa model that combines both the epithelium and the lamina propria compartments. To build the 3D scaffolds we chose hydrogels as materials to mimic the physicochemical and mechanical properties of intestinal tissue. Thus\, hydrogel conetworks of gelatin methacryolyl (GelMA)\, a natural polymer\, and poly(ethylene glycol) diacrylate (PEGDA)\, a synthetic polymer\, are photopolymerized. On one hand\, GelMA provides biodegradation and cell adhesion sequences but it lacks long-term mechanical stability. On the other hand\, PEGDA\, is non-biodegradable and does not present cell adhesion motifs. Nevertheless\, it has good mechanical properties. By this technique\, the lamina propria compartment of the intestinal mucosa can be reproduced in vitro. To do that\, GelMA and PEGDA polymers are laden with mesenchymal cells (fibroblasts or myofibroblasts) and/or immune cells (macrophages). We demonstrated that GelMA – PEGDA hydrogel co-networks support the growth of these cells and epithelial monolayers on top of the scaffolds. Embedding fibroblasts or myofibroblasts on the hydrogel conetworks enhance the formation and the maturity of the Caco-2 epithelial monolayers\, providing barrier properties similar to in vivo. The presence of the stromal cells also enhances the recovery of the epithelial integrity when the epithelium is temporally damaged. Finally\, an immunocompetent model is obtained by the encapsulation of macrophages in the constructs. The presence of macrophages does not influence the formation of the epithelium. However\, when the epithelial monolayer is disrupted\, the presence of mesenchymal and immune cells in the stromal compartment increases cytokine secretion in a synergistic manner. Our model can successfully mimic the interactions between stromal and epithelial compartments found in vivo intestinal tissue\, offering a potential platform to be used to study absorption and toxicity of drugs\, as well as cell behaviour under physiological and pathological conditions. \nLocation: The defense will be online.

SUMMARY:Online IBEC Seminar: Paul Verschure
DESCRIPTION:The volitional brain in action: counterfactual error and the virtualization of memory\n \nVolitional motor control can be seen as the result of a gradual replacement of feedback by feedforward control. We have addressed this question from the perspective of an integrated architecture called the Distributed Adaptive Control (DAC) theory of mind and brain. DAC proposes that the brain is a multi-layer control system which optimizes the how of action by considering why (motivation)\, what (objects)\, where (space)\, when (time) and who (agents) or the H5W problem. We have shown that for DAC to realize optimal solutions in foraging problems\, its decision-making renders policies that simultaneously optimize perceptual evidence\, memory bias\, goals\, and utility. This raises the question of what the principles are that underlie the processing and adaptation of these factors. In this presentation\, I will focus on a link between volition\, policy adaptation and perceptual learning we have recently advanced. The dominant model of anticipatory motor control relies on the notion of an inverse model that by learning from encountered errors acquires corrective responses that supersede feedback control. However\, these models are predicated on a Markovian world assumption and thus by necessity face problems in handling exceptions\, such as observed in probe trials\, where fast feedback control is required. We solve this challenge by proposing that adaptive motor control can also be obtained by relying on a cascade of purely sensory predictions that drive feedback control via counterfactual errors or Hierarchical Sensory Predictive Control. Using robot experiments\, we have demonstrated the robustness of this solution. I will present further supporting evidence for the relevance of counterfactual error in the physiology of motor learning\, the neurophysiology of human memory as obtained with intracranial recordings and in the rehabilitation of stroke patients.  In conclusion Paul will comment on the challenges involved in bringing science to society. \n\nPaul Verschure is Catalan Institute of Advanced Studies (ICREA) Research Professor\, Director of the Synthetic Perceptive\, Emotive and Cognitive Systems Laboratory at the Institute for Bioengineering of Catalunya and the Barcelona Institute of Science and Technology.

SUMMARY:Online IBEC Seminar: Xavier Trepat
DESCRIPTION:Mechanobiology of intestinal organoids\n \nXavier Trepat\, IBEC \nIntestinal organoids capture essential features of the intestinal epithelium such as folding of the crypt\, spatial compartmentalization of different cell types\, and cellular movements from crypt to villus-like domains. Each of these processes and their coordination in time and space requires patterned physical forces that are currently unknown. In this study\, we map the three-dimensional cell-ECM and cell-cell forces in mouse intestinal organoids grown on soft hydrogels. We show that these organoids exhibit a non-monotonic stress distribution that defines mechanical and functional compartments. The stem cell compartment pushes the ECM and folds through apical constriction\, whereas the transit amplifying zone pulls the ECM and elongates through basal constriction. Tension measurements establish that the transit amplifying zone isolates mechanically the stem cell compartment and the villus-like domain. A 3D vertex model shows that the shape and force distribution of the crypt can be largely explained by cell surface tensions following the measured apical and basal actomyosin density. Finally\, we show that cells are pulled out of the crypt along a gradient of increasing tension\, rather than pushed by a compressive stress downstream of mitotic pressure as previously assumed. Our study unveils how patterned forces enable folding and collective migration in the intestinal crypt. \nThis seminar will take place online at the Microsoft Teams Platform \nKnow more about Xavier Trepat’s research here

SUMMARY:PhD Thesis Defense: Dolores Blanco
DESCRIPTION:Noninvasive multimodal analysis of thoracic bioimpedance and myographic signals for the assessment of chronic obstructive pulmonary disease\nDolores Blanco\, Biomedical Signal Processing and Interpretation \nChronic respiratory diseases cause morbidity and premature mortality in adult population. In particular\, chronic obstructive pulmonary disease (COPD) represents a socioeconomic burden worldwide. COPD is usually evaluated by a spirometry test to quantify the airflow limitation. Classical spirometry requires the patients to move to the medical centers making difficult the continuous monitoring. Alternatively\, other noninvasive methods have been studied to monitor respiration because of their capability to provide valuable respiratory-related information. These techniques would lighten the intrusiveness of the measurements and ease the ambulatory monitoring of respiration. However\, the applicability of these methods into the clinics is still limited because of the lack of evidence in these applications. \nThe objective of this thesis is to propose and evaluate novel noninvasive methods to monitor respiration and assess obstructive diseases. We proposed a setup and a protocol to evaluate the applicability of thoracic bioimpedance and surface myographic signals for respiration assessment in healthy subjects and COPD patients. We acquired bioimpedance\, airflow and surface myographic signals in ten healthy subjects and fifty COPD patients. The physiological data was measured during an inspiratory threshold loading protocol to evaluate the methods during restrictive conditions. The thesis consisted of three different studies published in high impact factor journals. The two first studies delved into the changes of thoracic bioimpedance during restrictive breathing and\, the third one focused on the combination of bioimpedance and myographic signals for the assessment of COPD. \nPrevious studies showed a linear relationship between thoracic bioimpedance and respiratory volume during normal breathing. Firstly\, we assessed this linear relationship in healthy subjects for the first time\, during a loading protocol. We found a strong correlation between the signals even during highest loads. Nevertheless\, bioimpedance measurement is the combination of the different impedances of body tissues\, organs and fluids and consequently\, not only volume contributes to its measurement. Accordingly\, our second study aimed to evaluate the relevance of volume and chest movement to bioimpedance measurement at different levels of inspiratory muscle activity. We characterized bioimpedance using chest movement and volume signals by linear models and neural networks for different muscle effort. The results agreed with our previous results\, indicating that respiratory volume was the main contribution to bioimpedance\, but chest movement contributed substantially and more notably at high muscle activity. Both studies provided better knowledge of thoracic bioimpedance measurements which reinforces its use for noninvasive respiratory monitoring. \nFinally\, we evaluated the combination of thoracic bioimpedance and surface myographic signals in the COPD population. We proposed two novel ratios derived from the bioimpedance amplitude and myographic activity. These ratios showed significant differences between the mild and severe COPD patients meaning that the severest patients had lower inspiratory ventilation contribution of the inspiratory muscles. Consequently\, we suggest these novel ratios to provide valuable information to noninvasively monitor and complement the classical assessment of COPD. \nThe multimodal approach proposed in this thesis supports the application of thoracic bioimpedance for respiratory monitoring during normal and restrictive breathing. Furthermore\, the combination of bioimpedance and myographic information exhibited differences between COPD severity. The proposed methods will provide additional information about COPD condition which will be easily tracked by a single wearable device. Consequently\, the results of this thesis open up the way for a high-quality noninvasive monitoring of chronic respiratory patients. \n\nThis thesis defense will take place on Monday\, 9th November\, at 15:00 hours. \nLocation: The defense will be online using Microsoft Teams. People are invited to attend upon receiving a link that you have to request to Dolores Blanco (dblanco@ibecbarcelona.eu) or Raimon Jané (rjane@ibecbarcelona.eu).

SUMMARY:IBEC PhD Discussions Complementary Skills Session: #LancetGate and its broader implications for the pandemic response and science dissemination 
DESCRIPTION:#LancetGate and its broader implications for the pandemic response and science dissemination\nCarlos Chaccour\, ISGlobal\, Hospital Clínic\, Universitat de Barcelona \nOn May 22\, 2020\, the Lancet published an influential report on the use of hydroxychloroquine in COVID conducted using a vast database owned by a company based in Chicago: Surgisphere. The world counted more than 300.000 deaths due to the Pandemic at that time. The paper had an immediate impact on more than 131 clinical trials with this molecule ongoing worldwide at the moment\, including the WHO-led SOLIDARITY trial which put its hydroxychloroquine arm on hold due to safety concerns. The main issue\, of course\, is that the data was fraudulent. Hydroxychloroquine would finally be discarded as a potential treatment after failing randomized clinical trials. But the broader impact of the surgisphere “database” exceeded hydroxychloroquine and shaped the pandemic response in several latinamerican countries. In this talk we will review the story of what is now known as the #LancetGate scandal. \n\nCarlos Chaccour a results-oriented global health researcher that finds joy in looking at challenges from different angles. He is interested in the whole spectrum of problem solving\, from discovery to scale-up and believes that open-minded multidisciplinary teams are key to innovation.

SUMMARY:InsideScientific: Javier Burgués
DESCRIPTION:Decoding Turbulent Chemical Plumes with Improved Signal Processing and Machine Learning\nJavier Burgués\, Signal and information processing for sensing systems group \nMillions of years of evolution has aided animals and insects to develop the highly sensitive ability to track and navigate odor plumes over great distances.  This behavior is integral to their survival and propagation of the species; decades of research has gone into finding a way to replicate this inate behaviour in autonomous mobile robots.  And while it is accepted that animals are able to find hidden information from complex signals for odor navigation purposes\, the sub-Hz bandwidth of chemical sensors largely limits the efficacy of information retrieval.  Naturally\, this hinders the application of mobile robots for chemical source localization tasks. \nDuring this webinar sponsored by Aurora Scientific\, Dr. Burgués will discuss how he and his team are leveraging various signal processing and machine learning techniques in order to decode the fine-scale structure of turbulent chemical plumes using low-cost chemical sensors.  Specifically\, he will discuss three signal processing methods they developed to improve MOX sensor dynamics\, and share the experimental setups they used to test their theories. Finally\, he will share data from recent experiments and elaborate on the conclusions of their studies and how robotic plume tracking technology might apply to industrial and air quality monitoring\, research and more. \n\nYou can watch the seminar here

SUMMARY:PhD Thesis defense: Helena Lozano
DESCRIPTION:Electrical and topographical study of bacterial appendages at the nanoscale\nHelena Lozano\, Nanoscale bioelectrical characterization group \nSome bacteria can exchange electrons with non-soluble electron acceptors\, such as minerals. This phenomenon is called Extracellular Electron Transfer (EET) and it can be done through several mechanisms\, especially through conductive bacterial nanowires. \nThe main objective of this thesis is the investigation of the polarization properties of electrochemically active bacteria and their appendages. Specifically\, I have studied two types of bacteria\, Shewanella oneidensis MR-1 and cable bacteria. I have used the Electrostatic Force Microscopy (EFM)\, which measures the electrostatic force using a nanometric probe\, combined with finite element simulations to obtain the polarization properties. The electrostatic force depends mainly on the geometry and dielectric constant of the probe-sample system. \nFirst\, I have developed a way to obtain the dimensions of objects avoiding physical contact with the sample by measuring the electrostatic force. I have tested this technique on silver nanowires and bacterial flagella\, optimizing the EFM technique to nanowire-like biological samples at the nanoscale. Afterward\, I have studied S. oneidensis Outer Membrane Extensions (OMEs)\, responsible for the EET. I have obtained a low value of the dielectric constant (εOME=3.7±0.7). However\, considering that the conduction mechanism of such OMEs is through electron hopping\, where electrons are localized\, these results do not contradict the literature. \nI have also studied the cable bacteria\, especially the fibers that are along this filamentous bacterium. The dielectric constant of the fibers was εr=7±1. This result is not compatible with the conductivity reported in the literature. Therefore\, a core-shell model was proposed with a conductive core of h~10–20nm. \nSubsequently\, I have performed qualitative EFM measurements in liquid over living and rehydrated S. oneidensis bacteria. \nFinally\, I have performed macroscale measurements in living S. oneidensis using a microfluidic device that I designed\, fabricated and characterized at the Denmark Technical University (DTU)\, Copenhagen. It was used to perform two-electrode impedance measurements. \n\nIn order to attend to the defense\, you must send an email to the president of the Doctoral Commission of the Faculty of Physics (Dr. Eugeni Grauges Pous – vd.fisica.recerca@ub.edu) with a minimum notice of 48 hours and will be held via Microsoft Teams.

SUMMARY:Online IBEC Seminar: Santiago Marco
DESCRIPTION:Signal and Data Processing Workflows for Untargeted Chemical Analysis: Sensor Array and Mass Spectrometry Analysis of Complex Gas Samples\nSantiago Marco \, IBEC \nIn diverse sectors such as health\, food\, environment\, complex natural gas samples are analysed. Those samples can contain hundreds or thousands of compounds. In many cases\, the question to be answered does not require full separation\, quantification\, and identification of all compounds. Instead detection of abnormal samples (normal/ faulty)\, assignation of classes to samples (e.g.healthy/disease)\, or evaluation of global quantitative indexes (e.g odour intensity) is required. \nThe analysis of gas phase samples can be carried out with high-end lab equipment based on Chromatography-Mass Spectrometry or lower cost systems based on chemical sensors. In all cases\, the resulting raw signals/data need substantial efforts to extract the hidden information. In health applications the problem of biomarker discovery becomes like finding a needle in a haystack. Intimate knowledge of the instrumental problems and the sampling conditions is key for the correct interpretation of the results. \nThese problems are often addressed by building mega-variate predictive models using tools from machine learning. However\, in small sample conditions the possibilities to obtain overoptimistic results abound due to the curse of dimensionality. Careful model validation and statement of model validity domains is needed. \nThe seminar will take place online at the GoToMeeting Platform \nKnow more about Santiago Marco’s research here \n

SUMMARY:Online IBEC Seminar: Pere Roca-Cusachs
DESCRIPTION:Sensing the matrix: transducing mechanical signals from integrins to the nucleus\n \nPere Roca-Cusachs \, IBEC \nCell proliferation and differentiation\, as well as key processes in development\, tumorigenesis\, and wound healing\, are strongly determined by the properties of the extracellular matrix (ECM)\, including its mechanical rigidity and the density and distribution of its ligands. In this talk\, I will explain how we combine molecular biology\, biophysical measurements\, and theoretical modelling to understand the mechanisms by which cells sense and respond to matrix properties. \nI will discuss how the properties under force of integrin-ECM bonds\, and of the adaptor protein talin\, drive and regulate matrix sensing. I will further discuss how this sensing can be understood through a computational molecular clutch model\, which can quantitatively predict the role of integrins\, talin\, myosin\, and ECM receptors\, and their effect on cell response. Finally\, I will analyze how signals triggered by rigidity at cell-ECM adhesions are transmitted to the nucleus\, leading to transcriptional regulation. \nThe seminar will take place online at the GoToMeeting Platform \nKnow more about Pere Roca-Cusachs’ research here

SUMMARY:Online IBEC Seminar: Benedetta Bolognesi
DESCRIPTION:Deep mutagenesis to understand Protein Phase Transitions\n \nBenedetta Bolognesi \, IBEC \nSpecific insoluble protein aggregates are the hallmarks of many neurodegenerative diseases. Whether the protein aggregates themselves or other forms of the proteins are toxic to cells is still unclear in many of these diseases. This lack of understanding of the causes of cellular toxicity is reflected in the general failure of multiple therapeutic approaches so far attempted. The causes of this rely mainly on the lack of systematic approaches able to estimate in parallel the effect of mutations on cell viability as well as on protein conformation. Our lab uses deep mutagenesis as a systematic and unbiased approach to identify and investigate the toxic species of proteins. \nIn this seminar I will explain how we used this approach to report on the toxicity of thousands of protein sequences and how\, more recently\, we adapted this method to track more specific biochemical processes\, such as amyloid nucleation. Overall\, the results I will discuss demonstrate that deep mutagenesis is a powerful approach to study intrinsically disordered proteins and also illustrate that it can be used to genetically validate assays as discovery platforms. \nThe seminar will take place online at the GoToMeeting Platform \nKnow more about Benedetta Bolognesi’s research here

SUMMARY:Online IBEC Seminar: Giuseppe Battaglia
DESCRIPTION:Bionics at the molecular level: copying Nature to control Nature\n\n\nGiuseppe Battaglia \, IBEC \n\nA very established approach in medicine involves the replacement of organs or other malfunctioning body parts by synthetic versions\, engineered to mimic (or even augment it\, if you allow the sci-fi digression) the original function. Bionics is a very established medical discipline where engineering spouses the life sciences\, creating exquisite combinations. With the help of nanoscience and nanotechnology\, we can now push such an effort down to the molecular level. In our group\, we fabricate synthetic surrogates of trafficking vesicles\, viruses and\, one day perhaps\, even a whole cell. Such molecular bionic units offer more efficient solutions to deliver drugs\, to probe life at the nanoscale\, and to act as a model to understand biological complexity. \n\n\nOur efforts are intrinsically multidisciplinary\, and we mix chemistry\, physics and biology in all we do. We typically start studying biological complexity\, with a strong focus on transport\, trafficking and multivalent interactions (Physical Biology). To help this\, we develop new tools to look at biological systems in four dimensions capturing life’s spatiotemporal patterns (Microscopy). We thus apply a constructionist approach where we mimic biological complexity in the form of design principles such as compartmentalisation\, multivalency and taxis\, to produce functional units from simple building blocks and their interactions (Molecular Engineering).​ Finally\, we apply the resulting constructs to tackle disorders such as cancer\, neurodegeneration\, inflammation\, and infections (Nanomedicine). \n\n\nToday\, I start introducing our research activities giving a few examples of each segment\, to eventually focus my seminar on one of the latest and most exciting developments\, our understanding of multivalent interaction and how these control crucial biological processes\, such as cellular selectivity and trafficking. \n\nThe seminar will take place online at the GoToMeeting Platform \nKnow more about Giuseppe Battaglia’s research here

SUMMARY:Online IBEC Seminar: Elena Martínez
DESCRIPTION:Development of biomimetic models of intestinal tissue: guiding cellular self-organization through biofabrication techniques\n\nElena Martínez \, IBEC \nEpithelial tissues contain three-dimensional (3D) microstructures that guide cell self-organization at the tissue level. In the small intestine\, crypts and finger-like villi microstructures improve its absorbance function\, provides specific microenvironments and compartmentalizes cell types. Despite its physiological relevance\, tissue architecture and multicellular population are neglected in the standard in vitro models\, thus compromising their predictive capabilities. Our efforts in addressing these shortcomings by including key elements to mimic the native tissue in vitro will be discussed in this talk. First\, this will include strategies to promote cell’s self-organization capabilities giving rise to crypt-villus domains on 2D monolayers\, and strategies to engineer cell spatial positioning through micropatterning. Then\, our approach to include the 3D architecture of the tissue will be addressed. In here\, light-based biofabrication techniques to produce 3D villus-like structures will be discussed. Finally\, I will introduce our biofabrication proposal to produce tissue engineered models that include the epithelial and the stromal compartments. Improving the prediction capabilities of cell-based assays is a growing strategy to lead to more efficient drug development processes. As 2D-based systems are showing their limits\, new 3D strategies are gaining acceptance among the scientific community. Our approaches aim to further accelerate this trend by providing feasible strategies to routinely incorporate 3D multicellular structures at the tissue level in cell culture systems. \nThe seminar will take place online at the GoToMeeting Platform \nKnow more about Elena Martínez’s research here

SUMMARY:Online IBEC Seminar: Samuel Sánchez
DESCRIPTION:BioEngineering Hybrid Robotic Machines: from nanobots to 3D Bioprinted Robots\n \nSamuel Sánchez \, IBEC \nThe combination of biological components and artificial ones emerges into what we called hybrid machines/bots/robots. Here\, I will present two types of hybrid systems that we are currently developing in our lab which span across different length scales\, from a few nanometers to centimeters. \nAlike bacteria or small swimmers found in nature\, these artificial nanobots convert bio-available fuels to generate propulsion force to swim at the nanoscale. One of the dreams in nanotechnology is to engineer small vehicles which can eventually be applied in vivo for medical purposes. In the first part of my talk\, I will present how we bioengineer our hybrid nanobots combining the best from the two worlds: biology (enzymes) and (nano)technology (nano- micro-particles) providing swimming capabilities\, biocompatibility\, remote control\, multifunctionality and actuation. I will present some of the proof-of-concept applications such as the efficient transport of drugs into cancer cells and spheroids\, sensing capabilities and the use of molecular imaging techniques for their tracking and localization both in vitro and in vivo. \nIn the second part of my talk\, I will present the 3D bioprinting technique to fabricate hybrid 3D BIOBOTS which provides flexibility\, scalability\, rapid prototyping and simplicity. This technique has emerged as a powerful tool for the development of functional three-dimensional tissues and\, in particular\, skeletal muscle. By electrical stimulation\, we studied the adaptability of 3D hybrid Robots after long-term trainings and the force evolution during the trainings together with the dynamic gene expression. Two types of devices are bioengineered in our lab: (i) 3D Actuators which useful force measurement platform for drug screening against dystrophies and (ii) 3D BIOBOTS that can be a next generation of living soft robotics systems with swimming capabilities. \nThe seminar will take place online at the GoToMeeting Platform \nKnow more about Samuel Sánchez’s research here

SUMMARY:Online IBEC Seminar: Lorenzo Albertazzi
DESCRIPTION:A super-resolved look at nanomedicine\n \nLorenzo Albertazzi \, IBEC \nNanomaterials revolutionized the field of biomedicine introducing innovative approaches towards drug delivery\, molecular imaging\, regenerative medicine and biosensing. However\, despite the large investments in nanotechnology the translation into clinical applications is still unsatisfactory. One of the main reasons is the lack of knowledge about the behavior of nanostructures in the biological environment that makes the rational design of effective materials extremely challenging. \nThe main aim of our group is to use advanced microscopy techniques to understand the interactions of nanomaterials with living matter and to exploit this information to design novel devices for biomedical applications with a particular focus on drug delivery. To this goal we employ innovative optical imaging techniques such as super resolution microscopy to visualize and understand the molecular interactions of nanomaterials with their cellular targets in unprecedented detail. Super resolution microscopy techniques such as stochastic optical reconstruction microscopy (STORM) and point accumulation for imaging in nanoscale topography (PAINT) offer nanometric resolution and multicolor ability\, therefore they are ideal tools to study nano-sized multicomponent functional objects in vitro and in cells. This allows to get a closer “look” at the mechanisms of the key phenomena responsible for device performances such as particle stability\, protein corona and targeting. The fundamental knowledge acquired will pave the way towards the “microscopy-guided” design of novel nanomaterials for drug and gene delivery. \nThe seminar will take place online at the GoToMeeting Platform \nKnow more about Lorenzo Albertazzi’s research here

SUMMARY:Online IBEC Seminar: Javier Ramón
DESCRIPTION:Bioprinting methods for organ-on-a-chip applications\n \nJavier Ramón \, IBEC \nEngineered tissues in three-dimensional (3D) cell culture platforms that resemble the complex native structure and organization can be used as in vitro models to study tissues physiology and metabolism. Our technology allows us to develop a new platform to model metabolic and muscle diseases in vitro in order to study its response to candidate therapeutics and to better understand disease mechanisms of pathogenesis. To this end\, we monitor the secretion of disease-associated biomarker proteins and metabolites. \nHere\, we present 3D skeletal muscle constructs\, fabricated by encapsulating C2C12 cells and pancreatic mouse islets in a photocrosslinkable Gelatin Methacrylate (GelMA) and Carboxymethylcellulose Methacrylate (GelMA:CMCMA) hydrogel and cryogel scaffolds. These scaffolds present a microgrooved topography that promotes cell alignment and differentiation. These 3D tissues are integrated with biosensors for in situ monitorization of cytokines and hormones released under different external stimuli\, toxins\, drugs or electrical stimulation. \nWe have obtained a new platform to study the evolution of congenital muscle diseases\, specifically myotonic dystrophy 1 and evaluate the functional tissues by metabolic and gene expression analysis. Monitor the secretion of biomarkers proteins\, metabolites\, and the glycolysis pathway of muscle tissues for different drug candidates. Discussion: This platform has been tested with different drugs assays and represent a step toward the goal of producing in vitro drug testing systems for medical and pharmaceutical industry applications. Finally\, such “multi tissue-on-a-chip” devices can be fabricated using patient’s own cells as a major step toward personalized medicine. \nThe seminar will take place online at the GoToMeeting Platform \nKnow more about Javier Ramón’s research here

SUMMARY:PhD Discussions Sessions: Xarxa Quiroga and Adrián López
DESCRIPTION:Biochemical responses to cell membrane mechanical remodelling\nXarxa Quiroga\, Cellular and molecular mechanobiology\nIn a range of physiological processes\, from extravasation to endocytosis\, cells are constantly submitted to morphological changes\, which eventually entail plasma membrane reshaping and adaptation. This remodelling could be harnessed by cells to detect and respond to shape changes\, enabling mechanosensing mechanisms. However\, how this occurs is still largely unknown.\nTo increase our understanding on how such process can happen\, we have engineered a cell-stretching system that allows us to induce controlled plasma membrane remodelling while monitoring the whole process with the help of a microscope.\nBy using this set up\, we have found that cell de-stretch triggers the formation of transient membrane evaginations whose resorption is actively regulated by BAR protein recruitment and actin polymerisation. The described process may be the first part of a molecular cascade used by cells in response to stretch. \n\nDevelopment of Microphysiological Systems for the Evaluation of Regenerative Therapies\nAdrián López\, Biomaterials for Regenerative Therapies\nThe modelling of human organs has long been a task for scientist in order to lower the costs of therapeutic development and understand the pathological onset of human disease. Animal models remain the gold standard for drug discovery\, despite their widely recognized limitations such as their marked differences with humans in terms of genetics and etiology or their high cost. \nDuring the last decade\, the advancements in tissue engineering and microfabrication gave rise to innovative models known as organs-on-a-chip or microphysiological systems\, which aim to build functional miniaturized tissues in vitro that closely mimic the actual in vivo microenvironment. In this work\, we will present two microphysiological platforms that we are developing with the goal of understanding and evaluating biomaterial-based regenerative therapies. The first model is aimed at replicating the bone healing microenvironment to evaluate the angiogenic potential of calcium-releasing scaffolds. The second model will be focused on the generation of an ischemic injury on a physiologically relevant cardiac tissue to test if lactate-releasing scaffolds are able to stimulate cardiac tissue regeneration.
