Transforming growth factor-β, basement membrane, and epithelial-mesenchymal transdifferentiation: implications for fibrosis in kidney disease

PJ Stahl, D Felsen - The American journal of pathology, 2001 - ASIP
Interstitial fibrosis is characteristic of many clinical entities including diabetes, ureteral
obstruction, transplant rejection, and glomerulonephritis. 1 The interstitial fibrosis that
accompanies renal disease is a complex process involving derangements in both the
