Phenotype Image Detail
Image
Caption (A-D) Whole-mount (A and C) and parasagittal sections (B and D) of E9.0 wild-type (control) and Epn1tm1Ocr/Epn1tm1Ocr Epn2tm1Ocr/Epn2tm1Ocr (DKO) embryos. The mutant embryo is smaller than its wild-type counterpart, had an open neural tube (arrows) and did not undergo axis rotation in the sagittal plane. (E-H) Whole-mount (E and G) and hematoxylin and eosin stained cross sections (F and H) of yolk sac of wild-type and mutant embryos at E9.5; staining of whole-mount yolk sacs with the pan endothelial marker PECAM1 is shown in insets of fields (F) and (H). The H&E stained cross-sections reveal presence of large vascular sinusoids in the mutant yolk sac wall instead of the network of large and small vessels visible in the wild-type sample. Large vitelline vessels are absent from mutant yolk sacs [insets of (F) and (H)].
