Research Topics
Tissue engineering of bone, vascular and neural tissue / Development of biomaterials for tissue regeneration / Research at the biointerface between surface materials and biological entities / Surface functionalisation / Stem cells research Mesenchimal stem cells differentiation (Bone Regeneration), Endothelial Progenitor cells from Bone Marrow (Angiogenesis and Endothelisation), and Neural progenitor cells (Neural Regeneration) The Biomaterials for regenerative therapies research group is focused on the development of new third-generation bioactive and biodegradable materials for the treatment of diseased or altered tissues. The strategy used is known as tissue engineering and it involves isolating and cultivating progenitor cells and developing 3D structures or matrices that these cells can use as scaffolds to regenerate the specific tissue. The aim of these scaffolds is not only to provide support for the cells, but also to provide them with physical, chemical and biological signals appropriate to control and guide their activity in order to trigger self-regeneration of the specific tissue in the body.

calcium phosphate glass. The specific objective of the research lab is to design and develop new material surfaces by means of strategies such as their functionalisation using bioactive peptides or molecules able to mimic the extracellular matrix and promoting adhesion, migration and differentiation of specific cells for every type of tissue. The nano- and microstructure of the surface is also an important signal in terms of cell behaviour and consequently the topographic modification of surfaces may promote desired cell activities, such as preferential adhesion, migration, or even differentiation into cells of a more progenitor lineage. A number of technologies have been developed in order to produce the 3D matrices to be colonised by cells; these include robotic methods of rapid prototyping, electro-spinning and solvent casting.
The group has been working in elucidating the capacity of a composite material to induce angiogenesis in vivo and in vitro and has proposed a model that clarifies the effect of the chemical composition and the mechanical properties of the scaffold on the formation of new vessels. Using the same polymer of the composite, we have used electrospinning to create a network that helps neurons and glial cells to grow in a permissive environment for regeneration. Cells were oriented on the aligned nanofibers and maintained its immature phenotype. Following the same method, microfibers have been functionalised with collagen and fibroblasts have grown successfully creating a biohybrid tissue that can have applications on cornea, skin or ligament repair. Another fabrication method, rapid prototyping technique, has allowed obtaining composite scaffolds with well controlled structures that will be applied to bone tissue regeneration. Finally, polymer based microparticles have been developed to be used for drug and cell delivery.

We’ve all eaten rich meals or fatty foods and joked that we can feel our ‘arteries hardening’. However, the reality of atherosclerosis – when fat, cholesterol, and other substances build up in the artery walls and form solid structures called plaques – is no joking matter. The consequences of this disorder can include stroke and coronary artery disease, the leading cause of death in many developed countries.

The two IBEC-led CIBER-BBN tissue regeneration projects that were earmarked for funding by the EU's ERA-NET EuroNanoMed initiative last year (see www.ibecbarcelona.eu/IBEC-News/funding-success-for-two-ibec-projects.html) have both received the national support they need to get started.
