Phenotype of Plcg1 (−/−) embryos and Plcg1 gene expression. (A–C) Morphologic appearance of Plcg1 (+/+) and (−/−) embryos at the indicated embryonic age. (D–G) Plcg1 gene expression, as judged by β-galactoside staining, of a Plcg1 (+/−) embryo derived by TV-II targeting at the indicated embryonic days. (D) Posterior view of the embryo. a, allantois; op, optic placode; s, somite; h, heart; fb, forebrain; hl, hindlimb.
