Abstract

BACKGROUND: Previous studies have suggested mesenchymal stem cells (MSCs) as a suitable source for cell replacement therapy in diabetes. MSCs have successfully isolated from different adult and fetal tissues, including the pancreas. In vitro studies have shown that human fetal pancreatic stem cells could be extensively expanded and differentiated into islet-like structures. Here, we introduce a simple and cost-effective method for the generation of MSCs from the human fetal pancreas (FPMSCs). METHODS: To isolate FPMSCs, pancreata from four aborted fetuses (second trimester) were processed with short collagenase digestion. The resulting tissue fragments were transferred to a basic media (DMEM+15%FBS) without adding any growth factor. RESULTS: After 10 to14 days, fibroblast-like cells were harvested and passaged six times for further evaluations. Flow cytometry analysis and three-lineage differentiation capacity have demonstrated that these cells have MSC-like properties. We also continuously passaged samples of FPMSCs and found no evidence for chromosomal instability and morphological changes until 10th subculture. Moreover, our cell culture protocol can be easily modified and translated into a GMP-compliant one. CONCLUSION: The results of current study demonstrated that our simple and inexpensive method could yield a pure population of FPMSCs that might be suitable for transplantation.

摘要

背景:先前的研究表明间充质干细胞(MSCs)是糖尿病细胞替代治疗的合适细胞来源。MSCs已成功从包括胰腺在内的不同成人和胎儿组织中分离出来。体外研究表明,人胎儿胰腺干细胞可以大量扩增并分化为胰岛样结构。在此,我们介绍一种从人胎儿胰腺生成MSCs(FPMSCs)的简单且经济高效的方法。 方法:为了分离FPMSCs,对来自四个流产胎儿(孕中期)的胰腺进行短时间胶原酶消化处理。将所得组织碎片转移至不添加任何生长因子的基础培养基(DMEM + 15% FBS)中。 结果:10至14天后,收获成纤维细胞样细胞并传代六次以进行进一步评估。流式细胞术分析和三系分化能力表明这些细胞具有MSCs样特性。我们还对FPMSCs样本进行连续传代,直到第10代传代,未发现染色体不稳定和形态变化的证据。此外,我们的细胞培养方案可以轻松修改并转化为符合GMP标准的方案。 结论:当前研究结果表明,我们简单且廉价的方法可以产生可能适合移植的纯FPMSCs群体。
