| abstractText | Abstract Expression of serum and glucocorticoid-dependent kinase 1 (SGK1) during development in mouse kidney (embryonic day [E] 14 to postnatal day [P] 1) was studied by in situ hybridization and immunofluorescence. In whole embryos, SGK1 mRNA was highly abundant in the developing metanephros, where SGK1 mRNA was expressed in the ureteric buds of the branching collecting duct system and in the mesenchymal blastema-derived comma- and s-shaped bodies. In E14 kidneys, SGK1 protein was below detection level, whereas at day E16, ureteric buds, s-shaped bodies and outgrowing loops of Henle expressed detectable amounts of SGK1 protein. SGK1 protein was also expressed in E16 primary tubules of the collecting duct system. In P1 kidneys, no or only faint SGK1 protein expression was apparent in comma- and s-shaped bodies, whereas SGK1 was continuously expressed by medullary collecting ducts. In conclusion, SGK1 is developmentally expressed in metanephrogenesis. High expression in developing collecting duct and in blastema-derived comma- and s-shaped bodies suggests a dual function of SGK1 in maturation of the reabsorbing collecting duct epithelium and in epithelial transition of the blastema cells.
