Transforming growth factor-beta protein and mRNA in glomeruli in normal and diseased human kidneys.

Abstract

These results indicate that mature TGF-beta and TGF-beta-LAP are localized in association with the matrix components of GBM or mesangium, and with immune deposits in human glomeruli. Glomerular expression of TGF-beta is enhanced in human glomerular diseases, and may contribute to the mesangial matrix increase.
