文题释义:
人胎盘绒毛膜:
构成胎盘的胎儿部分,占胎盘主要部分。晚期囊胚着床后,滋养层细胞迅速分裂增殖,内层为细胞滋养层细胞,是分裂生长的细胞;外层为合体滋养细胞,是执行功能的细胞,由细胞滋养细胞分化而来。滋养层内面有一层细胞称胚外中胚层,与滋养层共同组成绒毛膜。
组织块法:将组织块剪成微小碎块,接种于培养瓶中,贴壁后加入细胞培养液培养,细胞从贴壁的组织块边缘缓慢爬出,直至爬满整个培养瓶,由于贴壁细胞没有经过酶消化,细胞受损伤较少,但也导致细胞分散度不高,爬出缓慢,耗时较长。

 

摘要
背景:关
于人胎盘绒毛膜间充质干细胞分离培养方法的研究很多,但是如何简便、快捷获得大量原代培养间充质干细胞的问题尚未解决。
目的:探讨优化人胎盘绒毛膜间充质干细胞体外分离培养组织块法的最佳方法。
方法:无菌条件下,取正常足月剖宫产胎盘绒毛膜,用匀浆器处理组织块,采用组织块法贴壁分离培养人胎盘绒毛膜间充质干细胞,经初次培养的组织块进行再次接种培养。 

结果与结论:用电动匀浆器处理人胎盘绒毛膜省时省力,组织分散度和去除红细胞效果好。初次培养和再次培养获得细胞的平均时间分别为(17.73±1.14) d和(10.03±1.30) d。每个Φ100 mm培养皿获得的原代细胞分别为(6.97±0.98)×105个和(13.82±1.44)×105个。获得的贴壁细胞呈典型的成纤维细胞形态,呈平行或漩涡状生长,高表达CD90、CD73、CD105,而CD45、CD34、CD14、CD19、HLA-DR为阴性。细胞可向成骨、成脂方向诱导分化。结果表明优化的方法能够简便、快捷地处理人胎盘绒毛膜组织,获得大量的原代间充质干细胞。

Abstract:

BACKGROUND: There are a lot of studies on isolation and culture methods of human placental chorionic-derived mesenchymal stem cells (hpcMSCs), but how to simply and efficiently harvest a large amount of primary MSCs has not been resolved.

OBJECTIVE: To optimize the tissue explants method of isolating and culturing hpcMSCs in vitro.
METHODS: Human placental chorionic villi were collected from full-term deliveries under aseptic condition and isolated by electric homogenizer. hpcMSCs were prepared by tissue explants method. The fluid and tissue of the primary culture flask and douching normal saline of the initial culture were centrifuged and prepared for secondary culture. 
RESULTS AND CONCLUSION: It saved time and effort to treat human placental chorionic villi with electric homogenizer, with good effects on tissue dispersion and removal of red blood cells. The average time of cell acquisition in initial culture and secondary culture was (17.73±1.14) and (10.03±1.30) days, respectively. The yields of primary cultured cells in initial culture and secondary culture were (6.97±0.98)×105 and (13.82±1.44)×105 per Φ100 mm culture dish, respectively. The adherent cells showed fibroblast-cell-like shape, which were in parallel or circinate arrangement. Highly expressed CD73, CD105 and CD90 could be detected in the third generation of hpcMSCs, but CD34, CD45, CD14, CD19 and HLA-DR were negative. Following induction, alizarin red staining and oil red O staining produced a strong reaction in cells. In a word, the optimized method is a simple and efficient method for obtaining a large amount of primary hpcMSCs.
