摘要
综述了鸟类原始生殖细胞的特性、起源、迁移等以及对 PGCs进行操作和培养 。
Primordial germ cells (PGCs) in avian are the progenitor cells for the gametes.These cells first appear in the epiblast.Then translocate to endoderm of germinal crescent area in the junction of the area opaca and area pellucida lateral to the primitive streak in stage 4 through 7.They separate from the endoderm.Temporarily circulate via the blood vascular system.leave the blood vessels.and finally settle down in the gonadal anlagen at stage 20～24 where they rapidly proliferate to form germ cells.The review is focusing on characteristics、origin、migrate route.maniipulation and culture of PGCS for production of transgenic chicken.
