| Outline of Final Research Achievements |
It was considered that formation of Angiogenesis-Osteogenesis coupling disturbance was necessary for occurrence of bone cell necrosis.
It was clear that prevention effect using BM-MSC was very high within 1 day after steroid administration.The effect of prevention in steroid-induced osteonecrosis rabbit models using Ex vivo extended BM-EPC was similar, and that an intravenous administration gives us the high osteonecrosis preventive effect indicated 1 day after steroid administration.And the prevention effects of steroid-induced osteonecrosis by using ex vivo extended BM-MSC and/or BM - EPC were higher than using BM-MNC .The formation of AOC disturbance plays the important role in the development of osteonecrosis, and we consider that this knowledge will be useful for future's study.Since it was clear that the problem in the prevention of osteonecrosis, however, we will continue this study.
