Fig. 2From: A modifier in the 129S2/SvPasCrl genome is responsible for the viability of Notch1[12f/12f] miceYolk sac vascularization in Notch1[12f/12f] embryos. Notch1[12f/+] mice that had been backcrossed 11 generations to C57BL/6 J mice were subjected to timed mating as described in Methods, embryos were dissected at E9.5, E10.5 and E11.5 and photographed using an inverted dissecting microscopeBack to article page
