Figure 1. The allantoic core domain houses putative precursor PGCs.

Figure 1

Schematic sagittal view of the embryo’s posterior region illustrating that precursor PGCs (red circles) are specified within the allantoic core domain (ACD; royal blue), which incorporates the primitive streak/epiblast. The inset shows an illustration of an entire embryo (~E7.25) to give context to the location of the mesodermal bulge that houses the ACD; the boxed area corresponds to magnified view. al, allantois; am, amnion; Epi, epiblast; ExE, extraembryonic endoderm; VE, visceral endoderm; D, dorsal; V, ventral; A, anterior; P, posterior.
