胚胎学的

During embryonic development, the blastula stage forms a hollow ball of cells that will eventually become the main body plan of the organism.
在胚胎发育过程中，原肠胚阶段形成一个空心细胞球，最终将发展成为生物体的主要结构。
The neural tube, a key structure in embryology, forms during gastrulation and gives rise to the brain and spinal cord.
神经管是胚胎学中的关键结构，在孵化期形成，它会发育成大脑和脊髓。
Embryonic induction is the process by which one region of an embryo influences the development of another region.
胚胎诱导是指胚胎中一个区域影响另一个区域发育的过程。
Embryonic stem cells have the remarkable ability to differentiate into any cell type in the body, making them valuable for regenerative medicine research.
