Glomerular epithelial cells(podocytes) play a key role in the prevention of proteinuria, are important determinants of end-stage kidney disease. Surface charge alterations of the podocyte may induce proteinuric injury. Cultured podocytes are currently being used to uncover unique functions of podocytes that can then be validated in vivo. Therefore, we examined a culture of podocytes on self-organized honeycomb-patterned films(honeycomb films). As a result, podocyte maintained their function for the mRNA expression of unique genes. In addition, we investigated the expression of glycosylation-related enzymes in cultured podocytes. We found that a honeycomb film showed higher podocyte function and angiotensin II stimulation decreased the mRNA level of these enzymes. These results suggest that glycosylation-related enzymes contribute to maintain the negative surface charge of podocytes.
