Tbx2, Tbx3, and Tbx4 expression in urogenital ridges at E11.5. Whole-mount ISH on dissected urogenital ridges, dorsal views (A–C) and ventral views (D, E), and section ISH on transverse sections are shown. Tbx2 is expressed in the epithelium of the Wolffian duct and mesonephric tubules (B, G). Tbx3 is expressed in the Wolffian duct epithelium and mesonephric mesenchyme, highlighted by dashed red lines (C, H). Tbx4 is expressed in gonads but not the Wolffian ducts or mesonephroi (D, I). Pax2 expression in the epithelium of the Wolffian duct and mesonephric tubules (A, F) and Oct4 expression in germ cells (E, J) are shown for comparison. Arrows identify Wolffian ducts and arrowheads identify mesonephric tubules. Dashed blue lines outline gonads in transverse sections. A, anterior; P, posterior; D, dorsal; L, lateral; M, medial; V, ventral; g, gonad. Scale bar in J = 100 µm (F–J).
