About
The “Biomimetic Systems for Cell Engineering” group is a multidisciplinary research group focussing its research activities on the development and application of new artificial systems that mimic tissue micro and nanofeatures for biomimetic in vitro assays.
The use of more biomimetic and complex 3D models in in vitro assays is now a hot and extremely relevant topic.
“Flat biology” results are questioned when being transferred to in vivo, while the pressure to decrease animal testing continues increasing. As a group of engineering providers working in the biotechnological field, we see these issues as both a challenge and a clear opportunity to impact the field with novel technological solutions. Our research ambition will be to develop better engineering tools to help in the development of organotypic cell culture models, easy to implement in daily cell culture routines, so they have a real and meaningful impact in the biotechnological arena and, therefore, will impact applications in basic cell research, disease modelling and regenerative medicine.
Along with this line, we are working towards the following objectives: (i) to engineer and validate a complex in vitro model of small intestinal epithelium, (ii) to validate a novel in vitro model of engineered cardiac tissue and (iii) to engineer a novel vessel-on-chip to reproduce the tumor metastatic environment. To carry out our research we employ cutting edge biofabrication technologies such as bioprinting and novel biological tools such as organoids.

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.
