FIG. 3.
Esco2, Setdb2, and Uba6 expression in the Embryonic Day (E) 14.5 fetal gonad. In situ hybridization of the E14.5 mouse ovary (B–D) and testis (F–H) with Esco2, Setdb2, and Uba6 antisense cRNAs. Cells with positive signal are colored mauve. No counterstain was applied in B, C, F, and G so that the positive signal in these tissues could more easily be viewed. Sense controls for both testis and ovary are shown in A and E, respectively. Bars = 20 μm. The arrows in each panel point to positively stained germ cells: yellow arrows, oogonia; green arrows, gonocytes.
