Fig 2. Double KO of Rap1a and Rap1b leads to lethality of majority of embryos before E10.5.

Fig 2

Stereoscopic images from two (A-C; D-F) of eight analyzed pregnancies resulting from Rap1a +/-, Rap1b +/- intercrosses. About 80% of Rap1a -/- ; Rap1b -/- embryos (A, B, D) fail to develop and pregnancy products are grossly malformed and non-viable. (E) Deletion of both Rap1b and one Rap1a allele leads to severe growth restriction; (C, F) littermate Rap1a +/-, Rap1b +/+ controls. Scale bar: 0.5 mm.
