摘要:

背景:以往研究证明胎盘间充质干细胞经诱导可以向骨、软骨、肌肉、脂肪等间充质细胞分化。
目的:探讨体外诱导胎盘间充质干细胞分化为表皮细胞的可行性。
方法:分离培养胎盘间充质干细胞,流式细胞仪鉴定其表面抗原,用含体积分数为2%胎牛血清以及20 μg/L表皮生长因子条件培养基诱导,诱导后细胞通过表皮细胞标志物CK19以及CK10染色鉴定。
结果与结论:胎盘间充质干细胞表面抗原CD29、CD44、CD105阳性,CD34、CD45、CD106以及HLA-DR阴性。诱导后细胞形态明显改变,表皮细胞标志物CK19以及CK10免疫荧光染色阳性,提示胎盘间充质干细胞在体外具有分化为表皮细胞的能力,可以作为皮肤组织工程和干细胞研究的一种有效来源。

Abstract:

BACKGROUND: The pervious study has showed that placenta mesenchymal stem cells (PMSCs) can differentiate into bone, cartilage, and muscle and adipose mesenchymal stem cells.
OBJECTIVE: To investigate the differentiation of PMSCs into epidermal cells in vitro.
METHODS: PMSCs were isolated and cultured and the surface antigen was detected by flow cytometry.
RESULTS AND CONCLUSION: Isolated PMSCs were positive for the markers CD105, CD29 and CD44 and negative for typical hematopoietic and endothelial markers CD34, CD45, CD106 and HLA-DR. The morphology of induced cells was obviously changed. Immunohistochemistry stain analysis showed positive for epidermal-specific markers like CK19 and CK10. The PMSCs have the capability to differentiate into epidermal cells in vitro. The placenta may prove to be a useful source of mesenchymal stem cells in skin tissue engineering and stem cells study.
