| Outline of Final Research Achievements |
Sufficient blood supply into any regenerative tissues and organs is mandatory for their long-time survival. In this study, we sought to determine if (1) co-administration of both stem cells and growth factors may facilitate inducing blood vessel maturation as well as increasing blood supply or vascular density and (2) co-administration of both stem cells and growth factors into the fascia flap which wrapped the beta tricalcium phosphate cube could also augment blood supply in order to regenerate bony tissue. The results showed that (1) maturation of the blood vessel was successfully induced by co-administration of both adipose derived stem cells and control-released basic fibroblast growth factor in both murine ischemic hindlimb model and wound healing model in diabetic mice, and (2) vessel maturation was also confirmed in prefabricated fascial model. However, we have not yet found any significant angiogenesis into the beta tricalcium phosphate.
