Drug discovery pathway relies heavily on in vivo animal models and in vitro cell mediums. In the case of animal models we have not only some ethical problems but also the ability to extrapolate data to human conditions is limited and in vitro platforms often do not simulate the complex cell–cell and cell–matrix interactions crucial for regulating cell behaviour.
The Biosensors for Bioengineering group is focused in a new line of research that has become of extreme importance in the last years. The idea is to integrate biosensor technology and nanotechnology with stem cell research and with tissue engineering. Engineered tissues are integrated with biosensing technology to obtain microdevices for detecting cellular responses to external stimuli, monitoring the quality of the microenvironment (e.g., metabolites, nutrients), and supporting diverse cellular requirements. This research on 3D-functional engineered tissues is expected to develop knowledge of tissue construction and their functions and relation with some human diseases. Integration of fully functional tissues with microscale biosensor technology allowed us to obtain “organs-on-a-chip”. These chips could be used in pharmaceutical assays and could be a step toward the ultimate goal of producing in vitro drug testing systems crucial to the medicine and pharmaceutical industry.

IBEC researchers were in the limelight today at the awards ceremony for the “la Caixa” fellowships and grants for research and innovation calls.
Today more than 300 researchers are meeting at CosmoCaixa to debate the latest scientific advances in cutting-edge fields at the yearly conference of the Barcelona Institute of Science and Technology (BIST).
IBEC group leader Javier Ramón presented the state-of-the-art in 3D printing of biomaterials at a workshop organised by CatalunyaBio & HealthTech last week.
To round off its first Faster Future fundraising campaign, IBEC is organizing an exclusive European film première of “I’ll Push You”, the inspiring story of Justin Skeesuck and Patrick Gray, the first people to complete the Camino de Santiago in a wheelchair.
IBEC has signed a collaboration agreement with the Federación Española de Enfermedades Raras (FEDER), a non-profit organization that represents the three million people suffering from rare diseases throughout the country.
Javier Ramon’s ‘muscle-on-a-chip’ that will use a patient’s own cells to study Myotonic dystrophy type 1 (DM1), the most common form of muscular dystrophy, is the subject of an article in El Periodico today.
The website of Faster Future, IBEC’s brand new fundraising programme, is now accepting donations.
Next week IBEC will launch Faster Future, a new crowdfunding initiative that aims to help accelerate research projects that are close to tackling major challenges in health.
Yesterday IBEC group leader Javer Ramon presented his research on developing organ-on-a-chip to study diabetes in IBEC’s public event forming part of this year’s Setmana de la Ciència.
This weekend Javier Ramon’s European Research Council-funded project, DAMOC, was one of eight highlighted in a special exhibition in Madrid to mark the ERC’s tenth anniversary.
IBEC’s Dr. Javier Ramón is one of just six researchers in Catalonia to have been awarded a 2016 Starting Grant by the European Research Council (ERC).
