The functions of some of these genes during embryogenesis have been studied in details.
我们也已经具体研究过一些基因在胚胎形成过程中的功能。
During embryogenesis and crown root formation, QHB expression was observed prior to the morphological differentiation of the root.
在胚发育和冠状根形成过程中，QHB在根的形态分化之前就已经表达。
Programmed cell death mediated by a process termed 'apoptosis' is the physiological cell death that occurs during embryogenesis, metamorphosis, normal tissue turnover and homeostasis.
程序性死亡即凋亡，在胚胎发育，变态，正常组织更新和自我平衡过程中都有发生。
During embryogenesis, capillaries develop in the fetus by neovascularization, where endothelial cells arise from progenitor cells; and angiogenesis, in which new blood vessels sprout from old ones.
在胚胎发育期，胎儿通过新血管化过程(其内皮细胞源于祖细胞)和新生血管形成过程(新血管由旧血管芽生而来)生成毛细血管。
APRT coding gene was active during the development of somatic embryogenesis, this indicated a way of nucleotide remedial synthesis existed during embryogenesis or embryo development in higher plant.
APRT编码基因在体细胞胚发育过程中的活跃表达，意味着在高等植物胚胎发生或发育过程中存在核苷酸补救合成途径。
Objective: To study the localization and in vitro culture of human embryonic primordial germ cell(PGC) during different stages of embryogenesis.
目的：对不同发育阶段的人胚胎原始生殖细胞（PGC）进行定位并比较其体外培养的差异。
The results described here strongly suggest that, like animal homeobox genes, OSH1 plays an important role in regionalization of cell identity during early embryogenesis.
此结果也有利的表明了，OSH1同动物异型盒基因一样，在胚胎发生的早期对细胞标识的区域化起到重要作用。
