原肠作用
原肠作用-
GFP在原肠作用期就开始表达，主要发生在中轴下胚层中；
GFP expression started during gastrulation in the axial hypoblast layer .
-
原肠作用是脊椎动物早期胚胎发育的关键事件。
Gastrulation is an essential event during early embryo development .
-
但在原肠中期以后处理的胚胎，神经系统发育基本正常，因此说明视黄酸并不抑制原肠作用和随后的神经诱导。
But the development of the CNS is almost mormal when embryos were treated with RA after the gastrula stage , then it did not inhibit the gastrulation and consequently neural induction .
