Expression patterns of took kit genes in paired fins. A, Wnt3 expression in the anterior ectoderm of the skate pectoral fin at stage 30. B, Gli3 expression in the posterior mesenchyme of the skate pectoral fin at stage 30. C, Msx2 expression in the anterior mesenchyme of the skate pectoral fin at stage 30. D, Bmp2 expression in the skate pectoral fin at stage 30. Dorsal view. E, Bmp4 expression in the skate pectoral fin at stage 30. Ventral view. F, Gli3 expression is enriched in the zebrafish posterior pectoral fin. G, Gli3 expression in the zebrafish pelvic fin at 21dpf. The expression is enriched in the anterior fin.
