Pronephric kidney development and the global expression of slc and cldn genes. (a) Hallmarks of pronephric kidney development in Xenopus laevis. Schematic representations of Xenopus embryos are shown with the embryonic stages and hours postfertilization (hpf), in accordance with the terminology established by Nieuwkoop and Faber [28]. Stage 12.5 and 20 embryos are dorsal views with anterior to the left. All other embryos are shown as lateral views. (b,c) Complexity of slc (panel b) and cldn (panel c) gene expression at defined stages of pronephric kidney development. The number of expressed genes at a given stage of pronephric kidney development was determined by whole-mount in situ hybridization.
