Along with the increase in the prevalence of lipid metabolism disorders,in vitro research on the adipocytes has been a hot topic in recent years. 3T3-L1 preadipocyte line is one of the most commonly used cell line for establishing adipocytes models. However,for 3T3-L1 cell lines,the traditional method,known also as the "Cocktail" method,have disadvantages including low transformation rate and heterogeneous conversion. Therefore,many studies aimed to improving the induction method by changing the time of inducers or adding other new drugs have been performed(known as the improved method). The present study was to summarize the progress of the traditional methods and the improved methods for inducing 3T3-L1 cell lines to mature adipocytes.
随着脂肪代谢性疾病的增多,有关脂肪细胞的体外研究成为近年来研究热点。3T3-L1前脂肪细胞系是建立成熟脂肪细胞模型最为常用的细胞系之一,但经典的脂肪细胞诱导方案存在转化率低、转化不均匀等问题。近年来,诸多学者通过改变诱导剂作用时间、增加新的诱导药物等方法,即改良诱导法,进行脂肪细胞模型的建立。本文主要从传统诱导法和改良诱导法两方面,总结了3T3-L1脂肪细胞诱导分化的研究进展。.
