Regenerative Medicine

The main objective is to identify the most effective strategies for repairing damaged nervous tissue that is dysfunctional due to trauma, aging and disease. We are achieving this through cell based therapy, particularly with the use of adult stem cells, genetically modified cells or biomaterials seeded with stem cells that are capable of mechanical and trophic support. The main impact is on autologous sources of mesenchymal stem cells (MSC) isolated from bone marrow and adipose tissue. Both are safe, relatively easily accessible cells that are tolerated without a substantial risk of immune rejection. Our previous studies clearly confirmed their paracrine actions via released trophic and growth factors, cytokines, chemokines, metabolites, and bioactive lipids which stimulate endogenous regeneration and influence immune response. Application of conditioned media (CM) containing bioactive factors released by stem cells has the same regenerative potential as direct transplantation of cells. Furthermore, CM contains extracellular vesicles (EVs) that mediate their paracrine effects by shuttling different types of RNAs (e.g., mRNA and miRNA) and proteins to recipient cells.


Therefore, in collaboration with Laboratoire PRISM – INSERM U1192, University Lille1 in France we are elucidating the protein cargo of stem cells-derived EVs and identifying candidate proteins and biological signatures associated with the postulated therapeutic effects.

Thus, delivery of CM-derived active factors may open the door to a new clinical approaches for CNS treatment. Our research efforts focus on carefully selected cell based or CM based therapy for treating: i) CNS trauma, and ii) dementia associated with cognitive impairment in older dogs. The main strategy of cell based therapy is to modulate inflammatory processes, improve recovery and axonal outgrowth and synaptic structures in damaged nerve tissue.
