| Outline of Final Research Achievements |
The objective of this research is to investigate the effect to bone regeneration of condensing platelet fibrin gel derived from autologous blood (Concentrated Growth Factors: CGF) and adipose-derived stem cells conditioned medium(ADSCs-CM). In culture examination, the behavior of angiogenesis of CGF was confirmed. The CGF implanted subcutaneously in rabbit back was disappeared before 4 weeks after implantation. In process of disappearance, many macrophages and newly formed vessels was seen around the CGF. The compressed and membranal CGF showed excellent mechanical properties characterized by high ductility with wide clinical application. The ADSC-MC contained PDGF, VEGF, HGF,and TGF-b, which are known to be necessary for tissue regeneration. This medium contained a high level of VEGF, HGF and TGF-b.
