Caption Embryo analysis. A: Mapk7tm1Wnt/Mapk7+ (ERK5+/-) and Mapk7tm1Wnt/Mapk7tm1Wnt (ERK5-/-) embryos were dissected out of the yolk sac and amnion at E9.0 (top), E9.5 (middle), or E10.0 (bottom). Mutant embryos are normal at E9.0 but start appearing smaller and paler at E9.5. At E10.0, mutant embryos are much smaller than the heterozygous controls, and mutant embryos often exhibit hypotrophic hearts with an enlarged pericardial sac (arrow). B: The yolk sac of a mutant embryo at E9.5 (upper panel) displays interconnected vasculature (arrow), which disappears by E10.0 (lower panel), resulting in a smooth and pale appearance.
