Objective: To review the research progress of growth factor sustained-release microspheres in fat transplantation.
Methods: The recently published 1iterature at home and abroad related the growth factor sustained-release microspheres in fat transplantation was reviewed and analyzed.
Results: The sustained-release microsphere carrier materials include natural polymer materials and synthetic polymer materials.The sustained-release complexes of different microsphere materials with different growth factors can promote the vascularization of transplanted fat in a timely manner, improve the survival rate of grafts, and reduce the incidence of complications such as liquefaction, calcification, and necrosis.
Conclusion: The growth factor sustained-release microspheres have the characteristics of persistence and controllability, which is a research hotspot in the field of fat transplantation and has broad application prospects.
目的: 综述生长因子缓释微球复合体在脂肪移植领域的研究进展。.
方法: 广泛查阅近年来有关生长因子缓释微球复合体在脂肪移植领域的国内外文献并进行分析总结。.
结果: 缓释微球载体材料包括天然高分子材料和合成高分子材料。不同缓释微球材料与不同生长因子相结合构成的缓释复合体能促进移植脂肪血管化，提高移植物成活率，降低液化、钙化和坏死等并发症的发生率。.
结论: 生长因子缓释微球复合体因具有持续性和可控性等特点，已成为脂肪移植领域的研究热点，具有广阔应用前景。.
