| Outline of Final Research Achievements |
Glomerular epithelial cells in the kidney (podocytes) play critical roles in maintenance of glomerular structure and glomerular ultrafiltration. Establishment of culture system remaining in vivo phenotypes of podocytes is essential for studies of podocytes, although podocytes drastically decrease podocyte-specific gene expressions with time in the primary culture. Of these, decrease in nephrin was the most evident. In this study, we evaluated effect of various culture conditions on the gene expression in primary culture of podocytes to improve phenotypes of cultured cells to restore in vivo phenotypes. Consequently, subculture on day 3 of culture of isolated glomeruli, detachment with non-enzymatic solution, addition of heparin, decrease in fetal bovine serum, adequate cell density, and extracellular matrices enable expression of podocyte-specific genes at the level of in vivo. In addition, dexamethasone and all trans-retinoic acid induce cellular processes of cultured podocytes.
