During the whole postembryonic development, GAS-IR cells were not detected in small intestine and rectum.

在蝌蚪的胚后发育过程中，小肠和直肠中没有检测到GAS阳性细胞。

So the ability to purify, culture, and manipulate these postembryonic stem cells would provide investigators with an invaluable cell source to study cell and organ development.

因此，对于研究发育生物学而言，能够分离纯化、培养和有效利用胚胎后亚全能干细胞，无疑具有非常重要的意义。
