摘要
背景:
随着再生医学推进,干细胞在疾病治疗中的使用频率逐步增高。目前在临床使用中,细胞数量、分化能力、异体接种时产生免疫排斥的可能性等因素都需要考虑,因此筛选出更适合临床使用的细胞种类显得十分有意义。
目的:比较人羊水、脐带、胎盘来源间充质干细胞的体外增殖能力、分化能力、运输液中细胞活性、免疫学特性,为临床应用提供选择依据。
方法:分别对3种细胞进行分离培养和免疫荧光鉴定,在体外诱导3种细胞成骨、成脂、成神经分化;qPCR检测成神经分化后的Nestin、NT-3、MANF表达量;流式细胞术定量分析HLA-ABC、HLA-DR的表达量;将3种细胞放于细胞运输液内常温放置24,48,72 h,计算活细胞数量。
结果与结论:①脐带间充质干细胞成脂能力最强,胎盘间充质干细胞成骨能力最好,3种细胞均可以表达神经细胞标志Nestin和GFAP;②成神经诱导后的胎盘间充质干细胞高表达NT-3,脐带间充质干细胞高表达MANF,分别可以用于不同类型的神经损伤修复;③羊水干细胞低表达HLA-ABC,不表达HLA-DR,更适合异体接种,产生免疫排斥的可能最低;④细胞运输液内储存72 h后羊水干细胞的存活率最高;⑤由于羊水、胎盘、脐带间充质干细胞在生物学特性上稍有差异,因此可根据其特点用于不同临床疾病治疗。

Abstract:

BACKGROUND: With the advancement of regenerative medicine, the use frequency of stem cells has gradually increased in the treatment of diseases. At present, several factors such as the number of cells, the ability of differentiation and the possibility of immunological rejection during allogeneic inoculation are taken into consideration in the clinical use of stem cells. Accordingly, it is very meaningful to screen out the more suitable type of stem cells for clinical use.
OBJECTIVE: To discuss the differences of mesenchymal stem cells (MSCs) derived from human amniotic fluid, umbilical cord and placenta in terms of the ability to proliferate in vitro, the ability to differentiate, the possibility of transport and the possibility of allogeneic inoculation, thereby providing evidence for the clinical application of MSCs.
METHODS: Three kinds of MSCs were isolated and cultured at first, and they were then identified by immunofluorescence and induced into osteoblasts, adipocytes and neuroblasts in vitro. qPCR was used to detect the expression of Nestin, NT-3, and MANF after neural differentiation. HLA-ABC and HLA-DR expression in these three kinds of MSCs was quantitatively analyzed by flow cytometry. Finally, the number of living cells was calculated at 24, 48 and 72 hours after they were placed in the cell transport solution at room temperature.
RESULTS AND CONCLUSION: (1) The adipogenic ability of placenta-derived MSCs and the osteogenic capability of umbilical cord-derived MSCs were the best among three kinds of MSCs. All three kinds of cells expressed Nestin and GFAP, which are markers of neural stem cells. (2) NT-3 was highly expressed in umbilical cord-derived MSCs after neural induction, while MANF was highly expressed in placenta-derived MSCs after neural induction. They could be used to repair different types of nerve injuries. (3) The human amniotic fluid-derived MSCs were more suitable for allogeneic inoculation because they expressed HLA-ABC in a low level and did not express HLA-DR which showed the lowest possibility to cause immune rejection. (4) The survival rate of amniotic fluid-derived MSCs was the highest after a 72 hours induction in the cell transport fluid. In conclusion, as there is a slight difference in biological characteristics of human amniotic fluid, umbilical cord and placenta-derived MSCs, these three kinds of MSCs can be used for clinical treatment of different diseases.
