Fig. 3. Tie2-Cre-mediated c-myc deletion did not affect
allantoic or placental vasculature but diminished hemogenic endothelial cells
in the aorta. (A,B) Allantoic explants stained for CD31 show
no obvious difference between the control and mutant. (C,D)
Placental vasculature at 11.5 dpc revealed by Tie2-lacZ reporter
assay shows no obvious differences between the control and mutant. Arrowheads
indicate the blood vessels. (E,F) H&E stained cross-section
of dorsal aorta shows hemogenic endothelial cells (arrows) in the control but
not in the mutant. Scale bars: 50 µm.
