摘要: 为探讨17β雌二醇(E2)对体外鸡胚原始生殖细胞(EPGC)发育的影响,采用EDTA胰酶解离法获得第28期鸡胚性腺中的PGCs,依据差速贴壁原理分离纯化PGCs,然后置于添加不同浓度 (0、5、10、20 ng/mL)17βE2的培养液中进行培养。结果显示,5 ng/mL 17βE2添加组与0 ng/mL 17βE2对照组相比,PGCs的发育能力无显著差异,而10 ng/mL和20 ng/mL 17βE2两添加组与0 ng/mL及5 ng/mL组相比,PGCs的发育能力差异显著(P<0.05)。但是,10 ng/mL和20 ng/mL 17βE2两添加组相比,PGCs的发育能力无显著差异。由此说明在体外环境中,一定浓度的17βE2(10 ng/mL、20 ng/mL)可促进鸡原始生殖细胞的发育。

Abstract: The effects of 17βestradiol (E2) on development of chicken primordial germ cells (PGCs) in vitro were investigated. Primordial germ cells, which were isolated from genital ridge of stage 28 chicken embryos with the method of EDTAtyrpsin collection, were purified by means of differential attachment technique and cultured in culture mediums of different 17βE2 concentrations (0 ng/ml, 5 ng/ml, 10 ng/ml and 20 ng/ml).The results indicated that there was no significant difference in development of PGCs between the group with 0 ng/ml and 5 ng/ml 17βE2. However, compared with the groups with 0 ng/ml and 5 ng/ml 17βE2, the groups with 10 ng/ml and 20 ng/ml 17βE2 had significant difference (P<0.05). But there was no significant difference in development of PGCs between the group with 10 ng/ml and 20 ng/ml 17βE2. The findings indicat that 17βestradiol of certain concentration (10 ng/ml, 20 ng/ml) promotes PGCs development in vitro.
