| Outline of Final Research Achievements |
It has been reported that BRONJ and DRONJ occurred in patients taking bisphosphonates and denosumab, respectively. However, the exact mechanism of ONJ is not clear. Moreover, definitive treatment strategies for ONJ have not been developed. On the other hand, adipose-derived stem cells and non-cultured stromal vascular fraction cells of adipose tissue have been demonstrated to have anti-inflammatory and regenerative effects on several injured tissues. Hence, the aim of this study was to investigate the transplantation effects of ADSC and SVF cells on BRONJ- and DRONJ-like lesions in mice. Both transplantation of ADSC and SVF ameliorated BRONJ- and DRONJ-like lesions. This healing effect was stronger SVF vs. ADSC transplantation. Hence, transplantation of non-cultured SVF cells of adipose tissue would become a novel treatment strategy of ONJ in human.
