Objective To observe whether laminin(LN) is expressed in the developing kidney of mouse and the changes of the expression associated with maturation and polarity. Methods Eight fetal and fourteen postnatal kidneys were examined by immunohistochemistry(Strepavidin Peroxidase conjugated method,SP),using polyclonal rabbit anti-mouse antibody. Results The expression of laminin in the kidneys increased with the gestational weeks of fetus and maturity of the kidney.The expression of laminin was positive in monocell,multicell without space and multicell with space.In the developing kidney,the laminin is expressed in the ureteric bud,glomerular basement membrane(GBM),tubular basement membrane(TBM),renal capsular basement membrane and interstitium.The expression of TBM was prior to the expression of GBM.Conclusion The expression of laminin in the developing kidney of mouse has chronological and spatial sequence.The laminin determines the polarity of cell.Laminin might play a key role during nephrogenesis.

Objective To investigate the influence of neuro-specific DNA repair gene Nbn on the development of granular cells in hippocampus of monatal mouse. Methods The hippocampus development of postnatal mouse was evaluated by comparing the morphological differences of granular cells in hippocampus between the Nbn gene knockout mice (Nbn-CNS-Del) and the controls (Nbn-CNS-Ctr). Serial sections, immunohistochemistry and stereology methods were used to quantitatively analyze the development of granular cells in hippocampus of mice on the postnatal day 7, 14 and 21 (P7d, P14d and P21d). Results In Nbn-CNS-Ctr group, the granular layer in hippocampus manifested "C" in shape, the section area of granular layer was increased, and so was the cell body of granular cells in hippocampus during P7d to P21d; the inner arm granular cells in granular layer of hippocampus emerged on P7d, and most obvious changes occurred during P7d to P14d. While in Nbn-CNS-Del group, the granular layer in "C" shape were seen to form in most of the specimens during P7d to P21d, though they were sparsely distributed. Compared with that of the mice in Nbn-CNS-Ctr group, the development of granular layer in hippocampus of the mice in Nbn-CNS-Del group lagged obviously, and the sectional area of granular cells decreased significantly (P

Objective To investigate the expression and cellular localization of metallothionein-1 (MT-1) in mouse kidney. Methods The adult male CD-1 mice were selected as experimental animals. The protein of MT-1 in mouse renal cortex and medulla was detected by Western blot assay. Immunohistochemistry and immunofluorescence methods were ap-plied to observe the location of MT-1 in renal tubules and collecting ducts of mouse kidney. Double-immunofluorescence and confocal laser scanning microscopy were used to observe the subcellular localization of MT-1 in the epithelial cells of re-nal tubules and collecting ducts of mouse kidney. Results The expression of MT-1 was detected in cortex and medulla of mouse kidney. The expression of MT-1was mainly found in proximal convoluted tubules and distal convoluted tubules of cor-tical labyrinth, and proximal straight tubules, distal straight tubules and collecting ducts of ray medullary and medulla of kid-ney. The strongest expression of MT-1 was found in proximal tubules, secondary in distal tubules and last in collecting ducts. The intracellular location of MT-1 was in brush border of proximal tubules and intracytoplasm, in the distal tubule epi-thelial cell cytoplasm and in the basolateral membranes of collecting duct epithelial cells. The subcellular localization was found in the lysosome. Conclusion The different locations of MT-1 expressed in proximal tubules, distal tubules and col-lecting ducts may determine different roles of them in kidney.
