Fig. 4.
Normal early testis differentiation in Amh−/− embryos. (A, and B) Gonads from wild-type (A) and Amh −/− (B) 11.5 dpc XY embryos were cultured for 48 h with ROSA26 mesonephroi. Similar levels of mesonephric migration were observed in both samples. (C, and D) Immunostaining for laminin (green) and PECAM-1 (red) on 12.5 dpc wild-type (C) and Amh −/− (D) XY gonads. Amh mutant gonads displayed normal morphology and coelomic vessel formation (arrows). (E, and F) Whole mount in situ hybridization for Sox9 expression in 12.5 dpc wild-type (E) and Amh −/− (F) XY gonads. Sertoli cell differentiation appears normal in Amh mutants, as demonstrated by Sox9 expression.
