Fig. 2From: The migratory pathways of the cells that form the endocardium, dorsal aortae, and head vasculature in the mouse embryoFormation of the head vasculature. The subfigures show Tal1 expression in fixed uncleared embryos, imaged by light sheet microscopy (a,b) and OPT (c). a: anterior view of the dissected anterior part of an E8 embryo showing that the dorsal aortae extend into the headfolds underneath the endocardium. b: bottom view of the anterior part of an E8 embryo, showing that the outflow tract of the endocardium starts to form as a semi-circle around the head folds. c: Side view of an E9.5 embryo, showing the dorsal aortae extending into the headfolds, past the heartBack to article page
