中文摘要:
      目的:研究人羊膜间充质细胞( Human amniotic mesenchymal cells,HAMCs)的分离、培养及其干细胞特性,为羊膜间充质细 胞在再生医学的潜在应用奠定实验基础。方法:无菌条件下取正常足月剖腹产胎儿的羊膜剪成碎片,经胰酶胶原酶序贯消化, DMEM/F12 培养,倒置显微镜下观察其形态,MTT法检测其生长规律,免疫荧光的方法对细胞进行鉴定,定向诱导方法检测细胞 的多向分化潜能。结果:来源于羊膜的间充质细胞,细胞免疫荧光显示SSEA-4,OCT-4阳性,具有很强的增殖能力,并且具有一定 的多向分化能力,在特定条件下可分化为脂肪细胞和成骨细胞;结论:羊膜间充质细胞能够在体外分离、培养、扩增,并且具有干 细胞特性。羊膜间充质细胞在再生医学和组织工程应用有很好的前景。
英文摘要:
      Objective: To investigate the isolation, culture and stem cells characteristics of human amniotic mesenchymal cells (HAMCs)for its potential application in regenerative medicine. Methods:Term placentas from healthy donor mothers obtained from caesarean sections were minced under sterile conditions. After sequential trypsin and collagenase digestion, cultivated in DMEM/F12, the morphololgy of HAMCs was observed under the microscope.Growth regularity was observed by MTT assay,the cell was identified by immunofluorescence, and it has multi-potential ability under specific conditions. Results: Mesenchymal cells derived from human amnion membrane, SSEA-4 and OCT-4 positive by immunofluorescence, It displays a strong proliferation and multipotential capacity .The cells can differentiate into fat cells and osteoblasts. Conclusions: HAMCs can isolation , culture and amplification in vitro, and these cells have stem cell properties . HAMCs has good prospects applications in regenerative medicine and tissue engineering.
