genital ridge

The migratory path of PGCs is: endoderm of yolk sac → endoderm of intestinal area → dorsal mesentery → genital ridge.

原始生殖细胞迁移路径为：卵黄囊内胚层→肠区内胚层→背肠系膜→生殖嵴；

the migration of the primordial germ cells ( pgcs), formation of the genital ridge, gonad sex differentiation, and their variations under different water temperatures were investigated using histological methods in the teleost, pseudobagrus vachelli.

通过组织学方法观察江黄颡鱼原始生殖细胞（PGCs）迁移、生殖嵴生成和性腺分化，并且探讨在不同温度培育下性腺分化的差异。

Migratory mode: from endoderm of yolk sac to endoderm of intestinal area is passive, from dorsal mesentery to genital ridge is active.

迁移方式：从卵黄囊内胚层到肠区内胚层为被动迁移过程；背肠系膜到生殖嵴为主动迁移过程；
