Abstract

Objective

The present study aimed to explore the efficacy and safety profile of liquid phase concentrated growth factor (LPCGF) in promoting autologous fat graft survival.

Methods

LPCGF/PRP was mixed with human fat tissues at different proportions and transplanted into nude mice. Three months after transplantation, the implanted fat tissues were retrieved for analysis. H&E staining was used to quantify the neovascularization. Immunohistochemical staining was applied to quantify the CD34-positive stem cells and the fluorescence intensity of VEGF and TGF-β.

Results

Addition of LPCGF to autologous fat reduced the fat absorption by 5–15%, especially at the early stage, and no complications were observed. In addition, the effect was improved with increased CGF. Liquid phase concentrated growth factor improves autologous fat graft survival, and the most suitable ratio of LPCGF/fat is 1:8.

Conclusion

LPCGF is rich in VEGF, TGF-β and CD34-positive stem cells, which can improve the fat transplantation effect, but the specific influence of a single component requires future evaluation.
