摘要
<正>间充质干细胞(MSCs)是在正常组织中发现的一种多能祖细胞[1],因其具有独特的自我更新能力和分化成脂肪细胞、骨细胞、心肌细胞、神经元细胞等组织特异性细胞的潜能[2-4],广泛用于再生医学研究,MSCs在组织损伤修复[4]、缺血性心肌病[5]、急性心肌梗死[6]、肝纤维化[7]等疾病治疗中发挥着重要作用。目前,面临的主要挑战是实现MSCs的大量来源及保证安全性,MSCs定义的主要特征是它的自我更新潜力、表面标记的表达以及多谱系分化能力,因此,向成脂肪细胞分化是鉴别MSCs不可少的部分。此外,MSCs的脂肪分化在再生医学研究中具有重要意义。从临床的角度来看,外科医生面临着患者软组织吸收重建的挑战。例如,烧伤患者经常遭受
