    摘要: Adipose tissue is not only an ideal material for soft tissue filling and augmentation, but also a plentiful source of regenerative cells in adipose-derived stromal vascular fraction. Enriched fat tissue with adipose-derived stromal vascular fraction cells (ADSVFCs) can improve the fat graft survival, as shown in previous studies. The objective of this study is to estimate the effects of various dosages of ADSVFCs on fat grafts. We hypothesized that the improvement of ADSVFCs on fat transplantation quality would be dose dependent. Fat tissues were obtained by liposuction surgery. ADSVFCs were mixed into fat tissue, and the ADSVFC-enriched fat tissues were implanted subcutaneously into nude mice. The histological findings showed that the neoangiogenesis and integrity of grafted fat cells significantly increased with increasing dosages of ADSVFCs. Higher dosages of ADSVFCs also significantly reduced the side effects of the fat grafts, including reducing inflammation, cell infiltration, fibrosis and cyst formation. In conclusion, ADSVFC supplemented fat implants can improve angiogenesis and anti-inflammation. However, these effects of ADSVFCs on fat graft quality are dose dependent.
