摘要: 为建立鸡小肠上皮干细胞(Intestinal epithelial stem cells,IECs)体外培养体系并对其进行生物学特性研究,取18日龄鸡胚,分离小肠获得IECs,在DMEM/F12培养基中培养并观察其形态。通过传代及生长曲线的绘制分析其增殖情况,并经形态学观察及细胞免疫组织化学、RT-PCR等方法对所得到的纯化后的鸡小肠上皮干细胞进行鉴定。结果表明,鸡IECs可在体外扩增培养,目前传代至P11,纯化所得的鸡小肠上皮细胞经形态学观察及免疫荧光、RT-PCR法鉴定为阳性,由此可得出结论:鸡小肠组织中可以分离出IECs,且能够在体外增殖培养。

关键词: 鸡, 小肠上皮干细胞, 分离培养, 鉴定

Abstract: This current study was conducted to investigate the biological characteristics of chicken IECs(Intestinal epithelial stem cells)by isolating and culturing in vitro.IECs were isolated from small intestine of 18 day-old chicken embryos.The suitable culture medium for IECs was DMEM/F12.Then its proliferation was analyzed by subculture and the growth curve.The purified chicken intestinal epithelial stem cells were identified by morphology,immunohistochemical methods and RT-PCR.The results showed that chicken IECs can be cultured in vitro and have been passed to 11 generation.The purified IECs were positive by morphology,immunohistochemical methods and RT-PCR.To sum up,IECs can be isolated from small intestine,which can proliferate rapidly in vitro.

Key words: Chicken, IECs, Isolation and culture in vitro, Identification
