摘要:

背景:脂肪干细胞是由中胚层发育而来的多能干细胞,在特殊的生长因子和环境等诱导培养条件下,可以向不同的谱系分化。
目的:详细阐述脂肪干细胞诱导分化的条件及鉴定方法。
方法:应用计算机检索万方数据库及PubMed数据库2005至2014年10年间的文献,中文检索词为“脂肪干细胞,诱导,分化”;英文检索词为“adipose derived stem cells,differentiation”。依据纳入排除标准选择37篇文献进行归纳总结。
结果与结论:脂肪干细胞在抗坏血酸、胰岛素、地塞米松、转化生长因子β作用下可向软骨细胞分化;成脂诱导液的配方包括3-异丁基-1-甲基黄嘌呤(IBMX)、胰岛素、地塞米松、吲哚美辛;成骨分化常用的诱导剂包含地塞米松或维生素D3、抗坏血酸,β-甘油磷酸钠;碱性成纤维细胞生长因子、表皮生长因子及维生素B27可联合应用诱导脂肪干细胞成神经分化;向心肌细胞分化普遍应用的诱导因子是5-氮杂胞苷;血管内皮生长因子和碱性成纤维细胞生长因子共同作用可以诱导脂肪干细胞向血管内皮细胞分化。随着分子生物学和细胞生物学的迅速发展,脂肪干细胞的分化研究也会更加深入,在目前对脂肪干细胞诱导分化现象观察的基础上,应加强对其内在的分子机制及调控脂肪干细胞可塑性的基因和蛋白的研究。

Abstract:

BACKGROUND: Adipose-derived stem cells are pluripotent stem cells developed from the mesoderm, which can differentiate into different lineages induced by specific growth factors and under certain environmental conditions.
OBJECTIVE: To describe the induced differentiation and identification of adipose-derived stem cells in detail.
METHODS: A computer-based search of Wanfang and PubMed databases was performed for relevant articles published from 2005 to 2014 using the keywords of “adipose derived stem cells, induced, differentiation” in Chinese and English, respectively. According to inclusion and exclusion criteria, 37 articles were selected in result analysis.
RESULTS AND CONCLUSION: Adipose-derived stem cells can differentiate into chondrocytes under the induction of ascorbic acid, insulin, dexamethasone, and transforming growth factor β. Recipe for adipogenic induction medium consists of 3-isobutyl-1-methylxanthine (IBMX), insulin, dexamethasone, indomethacin; and commonly used inducers for osteogenic differentiation include dexamethasone or vitamin D3, ascorbic acid, β-glycerophosphate. Basic fibroblast growth factor, epidermal growth factor and vitamin B27 may be combined to induce the differentiation of adipose-derived stem cells into neurons. 5-Azacytidine acts as a commonly used factor for inducing the differentiation of adipose-derived stem cells into cardiomyocytes. Combination of vascular endothelial growth factor and basic fibroblast growth factor can induce adipose-derived stem cells to differentiate into vascular endothelial cells. With the rapid development of molecular biology and cell biology, research on the differentiation of adipose-derived stem cells will be more in-depth. Based on the current observation of  adipose-derived stem cell differentiation, internal molecular mechanism as well as genes and proteins for regulation of adipose-stem cell plasticity should be explored in depth.
