摘要
[Objective] The paper was to establish embryonic stem cell system of goats. [Method] Numerous primordial germ cell colonies were derived from gonadal ridge and the surrounding tissues in 20 millimeter fetuses of down producing goat. Primordial germ cells and goats embryonic fibroblasts obtained from conceptus of equivaient gestational age were co-cultured. [Result] The colonies showed some characteristics of embryonic stem cells, such as the morphology of nest-like, they continued to be AKP positive and the ability to be continuously passed [Conclusion] These cells were pluripotent and ES-like cells.
[目的]建立绒山羊胚胎干细胞体系。[方法]采用与其胎儿成纤维细胞共培养的方式从20mm绒山羊胎儿生殖嵴及其周围组织分离克隆出大量原始生殖细胞(PGCS)集落。[结果]这些集落的细胞经过多次传代具有胚胎干细胞(ES)的诸多特征,如鸟巢状结构、AKP染色阳性、具有连续传代能力等。[结论]该细胞具有多能性,类似ES细胞。
