(A) Expression of Fanca at the P0 stage in (A) the epithelial cells of the developing collecting ducts of the kidney and (B) the developing tooth. Higher level of expression is noted in odontoblasts (o) than ameloblasts (a). (C) Expression of Fancain the hindlimb at E13.5 predominantly in mesenchymal cells (m) rather than in precartilage cells (p). Controls are shown as indicated in Fig2.
