Autologous fat transplantation has revolutionized soft tissue reconstruction, but conventional methods remain unpredictable as graft resorption rates are high due to lack of vascularization. The advent of adipose-derived stem cells (ASCs) has led to improvement of fat grafting outcomes, in part to their ability to undergo facile differentiation into adipose tissue, their angiogenic properties, and their ability to express and secrete multiple growth factors. This chapter discusses the isolation and characterization of human ASCs, its expansion in vitro, and relevant in vivo models for adipose tissue engineering.
自体脂肪移植已经彻底改变了软组织重建,但由于缺乏血管化,传统方法仍然不可预测,因为移植物吸收率很高。脂肪来源干细胞(ASCs)的出现改善了脂肪移植的效果,部分原因是它们能够轻易地分化为脂肪组织、具有血管生成特性以及能够表达和分泌多种生长因子。本章讨论了人 ASC 的分离和鉴定、其体外扩增以及脂肪组织工程的相关体内模型。
