文题释义:
密度梯度离心法:
是将样品加在惰性梯度介质中进行离心沉降或沉降平衡,在一定的离心力下把颗粒分配到梯度中某些特定位置上,形成不同区带的分离方法。此法的优点是:①分离效果好,可一次获得较纯颗粒;②适应范围广,能象差速离心法一样分离具有沉降系数差的颗粒,又能分离有一定浮力密度差的颗粒;③颗粒不会挤压变形,能保持颗粒活性,并防止已形成的区带由于对流而引起混合。此法的缺点是:①离心时间较长;②需要制备惰性梯度介质溶液;③操作严格,不易掌握。

 

摘要
背景:
关于恒河猴骨髓间充质干细胞的研究结果很有限,来自幼年恒河猴骨髓间充质干细胞的分化潜力仍然未知。
目的:探讨体外分离培养的恒河猴骨髓间充质干细胞生物学特性,对其生长曲线和表型进行初步鉴定。
方法:采用密度梯度离心法和全骨髓贴壁培养法提取培养幼年恒河猴骨髓间充质干细胞,利用MTS法绘制第2,7代骨髓间充质干细胞生长曲线,利用流式细胞仪分析法检测第3代骨髓间充质干细胞凋亡及第4代骨髓间充质干细胞表面标志物CD29、CD34、CD45、CD90、CD147表达,检测第3代骨髓间充质干细胞的成骨及成脂分化能力。
结果与结论:①第2,7代骨髓间充质干细胞在培养第一二天为潜伏期,第3-7天为对数生长期,第8天后细胞增殖逐渐减慢,进入平台期,第7代细胞增殖能力弱于第2代;②骨髓间充质干细胞表面标志物 CD90、CD29、CD147呈阳性表达,CD34、CD45呈阴性表达;③流式细胞仪细胞凋亡检测结果显示,73.83%为活细胞,21.76%为死亡细胞,4.27%为凋亡细胞;④骨髓间充质干细胞可诱导分化为成骨细胞与成脂细胞;⑤结果表明,分离培养的恒河猴骨髓间充质干细胞生长活跃,有较强的增殖及多向分化能力。

Abstract:

BACKGROUND: Studies on rhesus monkey bone marrow mesenchymal stem cells (BMSCs) are limited, and the differentiation potential of juvenile rhesus monkey BMSCs remains unknown.
OBJECTIVE: To investigate the biological characteristics of rhesus monkey BMSCs isolated and cultured in vitro, 
and to identify the growth curve and phenotype of BMSCs.
METHODS: BMSCs from juvenile rhesus monkeys were isolated and cultured by density gradient centrifugation and the whole bone marrow adherence methods. BMSCs at passages 2 and 7 were taken to draw cell growth curves by MTS method. Flow cytometry was used to detect apoptosis of passage 3 BMSCs and to detect expression of cell surface markers, CD29, CD34, CD45, CD90, CD147, in passage 4 BMSCs. Osteogenic and adipogenic abilities of passage 3 BMSCs were also detected.
RESULTS AND CONCLUSION: The BMSCs at passages 2 and 7 were incubated at first 2 days, logarithmically grew at 3-7 days, and then proliferated slowly at 8 days. The BMSCs at passage 2 showed stronger proliferation than those at passage 7. At passage 3, BMSCs were negative for CD34 and CD45, but positive for CD90, CD29 and CD147. Results from the flow cytometry showed that there were 73.83% living cells, 21.76% dead cells, and 4.27% apoptotic cells. BMSCs could differentiate into osteoblasts and adipocytes under osteogenic and adipogenic induction, respectively. To conclude, BMSCs from the rhesus monkey have strong proliferation and multilineage differentiation abilities in vitro.
