Development (2019) 146 (24): dev181107.
Published: 16 December 2019
...Ravindra S. Prajapati; Mark Hintze; Andrea Streit ABSTRACT During early embryogenesis, the ectoderm is rapidly subdivided into neural, neural crest and sensory progenitors. How the onset of lineage determinants and the loss of pluripotency markers are temporally and spatially coordinated in vivo...

Although epidermal fate is thought to be induced in vertebrate embryos, embryological evidence has indicated that no intercellular interactions during early...

...Daniel C. McIntyre; N. Winn Seay; Jenifer C. Croce; David R. McClay The border between the posterior ectoderm and the endoderm is a location where two germ layers meet and establish an enduring relationship that also later serves, in deuterostomes, as the anatomical site of the anus. In the sea...

The BF arises in the tail bud, caudal to the cloaca and in close association with the cloacal membrane, where the anal invagination (anal sinus) of ectoderm and the caudal endodermal wall of the cloaca are juxtaposed. Serial semi-thin sections of the tail bud...

Early asymmetric cell divisions at blastula and gastrula stages give rise to the superficial (apical) and the deep (basal) cell layers of epidermal ectoderm. These two layers consist of cells with different intrinsic developmental potential...
