Reduction of PGCs in Fancb mutant mice. (A–C) Immunostaining of mouse whole embryos at E9.5, E11.5 and E13.5. SOX2 is a marker for PGCs, and GATA4 is a marker for gonadal somatic cells. Scale bars: 100 µm. (D) Total numbers of the SOX2-positive PGCs per embryo at E9.5. (E) Total numbers of PGCs in each genital ridge (cells/genital ridge) at E11.5. Mean and SEM for independent mice are shown. Numbers of mice analyzed at E9.5 and E11.5, respectively: five wild-type and four Fancb mutant mice. *P < 0.05. Unpaired t-test.
