Figure 4

Summary figure describes new observations in the context of an existing model of the posterior region at headfold stages. The embryonic stage can be estimated based on the shape of the allantois, in this case, late headfold stage. Colors of letters and structures correlate. Blue marks mesothelium, red marks PECAM-1/CD41, green marks Flk1 and black marks visceral endoderm, allantois, amnion and embryo. The circular cluster is variable in size. DCM (dorsal cuboidal mesothelium); VCM (ventral cuboidal mesothelium); VOC (vessel of confluence); ACD (allantoic core domain); AX (allantois associated visceral endoderm or transitional visceral endoderm). The figure is modified from (Daane et al., 2011).
