Bone regeneration represents still a challenge, in particular for calvarium defects. Recently, the development of biomaterials with addiction stem cells is giving promising results treatment bone In particular, it was demonstrated that scaffolds enriched mesenchymal (MSCs) and/or their derivatives, such as conditioned medium (CM) and extracellular vesicles (EVs), may improve regeneration. Moreover, given deep link between osteogenesis angiogenesis, successful approach must also take into...
