Our research is focused on multi tissues organs-on-a-chip (OOC) and more specifically in the metabolic crosstalk within tissues and their relationship with metabolic diseases. Our projects are focused on four key tissues regulating glucose homeostasis, namely, the pancreas, liver, skeletal muscle, and adipose tissue. To achieve this objective, it is necessary a combined interdisciplinary approach:
-Biomaterials and tissue engineering research
1) We have several lines of research related with skeletal muscle. Our first approach was with C2C12 mice cell line. We evaluated the influence of mechanical stiffness and geometrical confinement on the 3D culture of myoblast-laden chemically modified gelatin photo-cross linkable composite hydrogels in terms of in vitro myogenesis.
2) Encapsulation of beta-cells like from human skin fibroblast (collaboration with IDIBAPS). This work addresses two critical issues in the design of an efficient beta-cell replacement therapy: an accessible cell source for generation of substitute beta-cells and an adequate delivery device for transplantation. On one hand, we propose to generate transplantable functional insulin-producing beta-cells from fibroblasts through direct reprogramming strategies that bypass the pluripotent iPS stage. On a second objective, we are working in a new system of encapsulating beta-cells like in two steps, microencapsulation to protect cells from immune system and microencapsulation to mechanically protect them and manipulate them.
3) We are developing three-dimensional micro liver models using various biomaterials to recreate the in vivo-like mechanical properties and using hepatocytes and stellate cells. We are collaborating with Grifols company to test some drugs in our model.
4) We have a collaboration project with NovoNordisk to work in new approaches to encapsulate retinal cells.
1) Integrating biosensors in an organ-on-a-chip. We are studying with in situ electrochemical biosensors the release of insulin under the effect of external stimuli, changes in glucose levels and myokines secreted by skeletal muscle (multi-OOC approach).
2) Related with this project we are implementing new biosensors systems. To fully exploit the potential of the organs-on-a-chip, there is a need to interface them to integrated sensing modules, capable to monitor in real-time their biochemical response to external stimuli, like stress or drugs. The goal of this project is to answer this need, by developing a novel technology based on integrating localized surface plasmon resonance (LSPR) sensing module to organs-on-a-chip devices to monitor disease and evaluate drug response in organs-on-a-chip models.
3) Myotonic dystrophy type 1 (DM1) (collaboration with Hospital de la Fe and INCLIVA, Valencia, Spain). We have developed human skeletal muscle micro physiological tissues using micro molding technology and we have integrated them with amperometric biosensors to study the inflammatory process related with electrical and chemical stimuli. We have used transdifferentiated skin fibroblast human cells from DM1 patients and healthy human. Using this platform, we have started to evaluate different treatments, to screen drugs and to evaluate doses.
4) NMR integrated with OOC. The objective of this project is to develop a new technology based on magnetic resonance spectroscopy and imaging using dynamic nuclear polarisation (DNP-MR) integrated with OOC devices to monitor disease and evaluate drug response in OOC models. As a proof-of-concept, this project will fabricate a biomimetic multi OOC integrated device composed of liver spheroids and pancreatic islets and develop the necessary DNP-MR hardware and software to study metabolic diseases and for future drug screening applications. We are working in collaboration with Oxford instrument and Multiwave companies.

The Institute for Bioengineering of Catalonia (IBEC) launches the Faster Future “A por la COVID19” campaign, with the aim of raising the 100.000€ needed to accelerate three research projects in collaboration with hospitals and patients associations.
From 31st October until 7th November participants from different fields and nationalities participated in the 3rd edition of the Innovation Day (i-Day), a series of events organised by EIT Health in partnership with local research and health institutions.
Several researchers from IBEC have been awarded for their quality in spreading the word of bioengineering. From scientific talks, to videos and posters, IBEC scientists and engineers show their talent inside, but also, outside the lab.
Researchers from the Institute for Bioengineering of Catalonia (IBEC) have developed an innovative scaffold that allows muscle tissues growth at the millimetre scale in the laboratory.
This technology opens the door to potential applications in fields such as organ transplantation and engineering, drug screening and disease modelling.
Javier Ramón, Group Leader of the “Biosensors for Bioengineering” group at IBEC, has been appointed new Research Professor at the Catalan Institution for Research and Advanced Studies, ICREA. Currently IBEC hosts 8 ICREA Professors out of 22 group leaders.
Since last April 1, Dr. Javier Ramón, Group Leader at IBEC, has become part of the ICREA Research Professors community. ICREA is a foundation funded by the Catalan Government aimed at recruiting the most extraordinary and talented international scientific researchers. With this appointment, IBEC hosts 8 ICREA Professors and 2 ICREA Academia (UB affiliated professors), one of the highest numbers among all research centres in Catalonia.
A group of researchers from the Institute for Bioengineering of Catalonia (IBEC) leads the European project BLOC, an initiative led by researchers Javier Ramón and Irene Marco that seeks to evaluate the response to different drugs in metabolic diseases using organ-in-a- chip by using nuclear magnetic resonance (NMR). For this, the consortium will have a budget of almost 3 million euros, financed by the Horizon 2020 FET Open program.
Irene Marco explains at BigVan, the scientific section of La Vanguardia journal, how thanks to microfluidics and research based on the use of “organ-on-a-chip” devices, we can go a step forward towards personalized medicine.
During the 29th to 31st of October, IBEC participated in the fourth edition of “INDUSTRY: From Needs to Solutions”, the international meeting dedicated to 3D printing, and also the HELTHIO Days where Josep Samitier moderated the round table on 3D printing applications in healthcare.
In its fourth edition, IN(3D)USTRY becomes INDUSTRY to include more industrial sectors, the main goal is to cover the entire value chain and provide intelligent manufacturing solutions. The institute had a stand in the exhibition area, where the representatives of the IBEC Technology Transfer office welcomed the interested visitors to learn more about the 3D bioprinting capabilities of IBEC.
