Moldless approach to generate 3D intestinal tissue model using hydrogels

The Biomimetic systems for cell engineering group has developed a new method to generate 3D intestinal tissue using hydrogels. This new in vitro model has been improved by providing cells with a more physiologically realistic environment, including tissue architecture, cell-matrix interactions and chemical signalling while remaining compatible with standard cell characterization techniques.

Epithelial tissues contain complex three-dimensional microtopographies that are essential for their proper performance. These 3D microstructures provide cells with the physicochemical and mechanical signals needed to guide their self-organization into functional tissue structures and are key to their proper functioning.

Third IBEC student wins PIONER prize for thesis

Jemish Parmar from IBEC’s Smart Nano-Bio-Devices group has been awarded a Premi Pioner from CERCA for his Doctoral Thesis “Micromotors for Environmental Applications”.

Since their launch in 2014, the prizes recognize researchers who present a doctoral thesis with results that are clearly aimed at commercial exploitation. The third IBEC winner of one of these prestigious awards, Jemish was honoured alongside the three other winners – from ICFO, CTFC and IGTP – at a ceremony yesterday.

The jury in this fifth edition of the Premis Pioner was made up of Eduard Balbuena (Enterprise Department at UAB), Josep Maria Pujals (IP lawyer at Oficina Ponti), Melba Navarro (Knowledge Transfer Technology Manager at CIMNE Tecnologia), Anna López Lozano (IP expert),

Improving in vitro models to study the human intestine

IBEC’s Biomimetic Systems for Cell Engineering group has published a review about possible new strategies to study drug absorption in the intestine in the high-ranking journal Trends in Molecular Medicine.

Together with their collaborators at the Universidade do Porto, Elena Martinez’s group examines the current state-of-the-art of cell-based intestinal models, which have been used for drug absorption and metabolism studies since the 1980s. However, current models, which use Caco-2 cells derived from human intestinal tumors, are not fully representative of the human small intestine.

Deciphering cell language

New insights into the intercellular communications mechanism that regulates cell repositioning leads the way towards the development of targeted therapies in regenerative medicine

Understanding the language of cells in order to redirect them when necessary: this is one possibility unveiled by researchers at the Center for Regenerative Medicine of Barcelona (CMR[B]), led by Dr. Samuel Ojosnegros, who describe in their latest paper the intercellular communications mechanism involved in cell relocation.

The work, published in Proceedings of the National Academy of Sciences (PNAS), was carried out in collaboration with the groups of Elena Martínez (IBEC) and Melike Lakadamyali (ICFO), among others. The fruitful collaboration also gave rise to the publication of work by Verónica Hortigüela, former PhD student in Elena’s group, who bioengineered a nanopatterning strategy that provides control over this communication mechanism.
