epiblast

epiblast

1. Most grass embryos have a flap-like structure known as the epiblast

大多数禾本科胚有一片瓣状结构通常称为外胚叶。

2. During early embryo development, Foxd3 mRNA has been detected in blastocyst-stage embryos and throughout the epiblast of the 6.5 days postcoitum (dpc) embryo.

实验发现Foxd3基因敲除的胚胎在E6.5天死亡,并且表现为epiblast的减少,取而代之的是近端胚外组织(proximal extraembryonic tissue)。

3. At least two different states representing the epiblast progenitors in the blastocyst and the pluripotent progenitors of the later gastrulating embryo have been recognized.

最少两种代表不同的发育状态已得到确认，一种是胚泡中的外胚层祖细胞，另一种为晚期原胚多潜能祖细胞。

4. embryonic epiblast

胚表层

5. The teams reported that they found the new cells in the innermost cell layer, the epiblast, of one week old rodent embryos, rather than in a ery early stage embryo where ordinary ES cells are found.

这个研究小组报道称他们在一周大的,啮鼠动物的外胚层细胞层的最里发现这些新细胞，比起早期每个阶段胚胎的胚胎干细胞发现的地方，这里更多些。
