Fig. 5. Aberrant interzone formation in Prx1-Hif1 ${alpha}$ autopod. (A-D) In situ hybridizations for Gdf5. Whole-mount at E12.5 (A) and E13.5 (B) and sections at E13.5 (C) and E14.5 (D) show noticeable differences in the expression patterns between Prx1-Hif1 ${alpha}$ and control; white and black arrowheads indicate interzone area. (E) Noggin expression at E14.5. Red arrows indicate interzone area. (F-I) Higher magnification of the joint located between the first and the second phalanges of E15.5 control and Prx1-Hif1 ${alpha}$ autopods. (F) H&E staining. (G-I) Sections were hybridized with RNA probes for Gdf5 (G), Wnt9A (H) and Bmp2 (I).
