文题释义:
MTT法测量细胞增殖:
活细胞线粒体内的琥珀酸脱氢酶能够使外源MTT还原为不可溶状态,通过酶标仪检测490 nm波长处的吸光度值,间接反映活细胞的数量和活力。
碘化丙啶检测细胞周期:在细胞周期的不同阶段,细胞内的DNA含量不同,碘化丙啶能够嵌入到DNA中,并且在激发光的作用下释放红色荧光,通过检测荧光的强弱间接反映细胞内DNA的含量和所处的细胞周期阶段。

 

摘要
背景:
间充质干细胞的来源以及分离方法越来越多样,充分认识到这些间充质干细胞的异同,将有助于间充质干细胞在临床中更加合理规范的应用。
目的:比较不同组织来源间充质干细胞的生物学特征。
方法:采集剖宫产产妇在生育后脱落的脐带、胎盘以及部分脂肪组织,采用胰酶消化法或组织块贴壁法培养出底蜕膜间充质干细胞、绒毛膜间充质干细胞、脂肪间充质干细胞、脐带胎盘连接处间充质干细胞、脐带间充质干细胞,所用的干细胞培养基有3种:含胎牛血清的干细胞培养基、含脐血裂解物的干细胞培养基、含无血清添加物的干细胞培养基。检测不同培养条件下的细胞直径、表面标志物以及多向分化能力,检索GEO数据库分析不同间充质干细胞的基因表达情况。
结果与结论:①不同培养条件影响细胞大小和细胞周期,其中无血清培养体系培养的间充质干细胞直径偏小,而脐血裂解物干细胞培养基能够增加胎盘源间充质干细胞的直径;②5种间充质干细胞有类似的表面标志物,都具有成骨、成软骨和成脂肪分化能力,其中脂肪间充质干细胞成脂肪分化能力更强;③脂肪间充质干细胞相比于与其他4种干细胞在基因表达上存在较大差异,具有更复杂细胞基质成分。

Abstract:

BACKGROUND: Various methods have been introduced to isolate mesenchymal stem cells of different origins. A full understanding of similarities and differences among mesenchymal stem cells of different origins will contribute to the rational and standardized application of mesenchymal stem cells in clinical practice.
OBJECTIVE: To compare the biological characteristics of mesenchymal stem cells of different origins.
METHODS: We collected umbilical cord, placenta and part of adipose tissues that were shed from parturients after cesarean delivery, and decidua basalis-derived mesenchymal stem cells, chorionic villi-derived mesenchymal stem cells, adipose-derived mesenchymal stem cells, mesenchymal stem cells at the junction between umbilical cord and placenta, and umbilical cord mesenchymal stem cells were cultured by trypsinization or tissue explant method. There were three kinds of stem cell culture media, including stem cell culture medium containing fetal bovine serum, stem cell culture medium containing cord blood lysate, and serum-free stem cell culture medium. Cell diameter, surface markers and multi-directional differentiation ability under different culture conditions were examined. Gene expression of different mesenchymal stem cells was analyzed by retrieval of the GEO database.
RESULT AND CONCLUSION: Under different culture conditions, there were no differences in cell size and cell cycle. The diameter of mesenchymal stem cells cultured in serum-free culture system was decreased, while the diameter of placenta-derived mesenchymal stem cells cultured in the stem cell culture medium containing cord blood lysate increased. Mesenchymal stem cells of five origins had similar surface markers, osteogenic, chondrogenic and adipogenic abilities, in which adipose-derived mesenchymal stem cells have stronger adipogenic ability. Moreover, adipose-derived mesenchymal stem cells are different from other kinds of stem cells in term of gene expression, and have complex extracellular matrix.

Key words: mesenchymal stem cells, tissue explant method, trypsin digestion, mesenchymal stem cells at the junction between umbilical cord and placenta, umbilical cord mesenchymal stem cells, adipose-derived mesenchymal stem cells, decidua basalis-derived mesenchymal stem cells, chorionic villi-derived mesenchymal stem cells
