Abstract:
Mesenchymal stem cells (MSCs) have the potential to directly differentiate into osteogenic cells and efficiently regenerate bone tissue. Adipose-derived stem cells (ASCs) have the potential to differentiate into an osteogenic lineage, too. In addition, ASCs can be readily harvested in large numbers with low donor-site morbidity. Meanwhile, recent reports have demonstrated that platelet-rich plasma (PRP) contains a variety of growth factors and may be a powerful biological autologous cocktail of growth factors for tissue engineering.We have shown that ASC/PRP admixture had dramatic effects on bone regeneration in a rat calvarial defect model, not only through the osteogenic potential of ASCs, but also through the release of cytokines by platelets in PRP, which, in turn, support ASCs.In this chapter, we introduce the bone regeneration using a combination of ASCs and PRP in a rat calvarial defect model.
