Progression of kidney disease is characterized by the sustained release of proinflammatory and profibrotic cytokines and growth factors, leading to renal fibrosis. TGF-β is considered to be one of the main regulators of fibrosis, but preclinical studies have revealed important synergistic roles for other growth factors, including CTGF, EGF and PDGF, in this process. Here, the authors discuss the roles of these growth factors in kidney fibrosis, as well as the evidence supporting their qualification as additional targets for novel antifibrotic therapies.
