Research Abstract

To clarify the interaction between glomerular epithelial cells and mesangial cells, we examined ^3H-thymidine incorporation of mesangial cells in co-culture with epithelial cells using permeable type I collagen membrane.
Thymidine uptake of mesangial cells decreased by co-culture with epithelial cells until 60% of control (without epithelial cells). By co-culture with mesangial cells, thymidine uptake of mesangial cells did not change. In the same condition, IU-beta addition increased thymidine uptake of mesangial cells without epithelial cells. But co-culture with epithelial cells suppressed this mesangial proliferation induced by IU-beta.
These results indicate that glomerular epithelial cells regulate mesangial proliferation under both physiological and pathological states. It was speculated that pathological states such as glomerulonephritis brake the regulation by epithelial cells and induce mesangial proliferation.
