Fig. 3. Gene expression of chondrocyte-maturation-associated genes is depressed in Kif3a-deficient synchondroses. Serial sections from the medial portion of P7 control (A-E) and Kif3a-deficient (F-J) spheno-occipital synchondroses were processed for in situ hybridization analysis of the indicated genes, using radiolabeled riboprobes. The hybridization signal was given artificial colors and images were superimposed with hematoxylin histologic images of the corresponding field. Scale bar: 100 µm in J for for A-J.
