Aimed at observing the biological effect of CTGF, we set up a cell line overexpressing CTGF, and analyzed the amount of myofibroblast and the level of extracellular matrix Collagen Ⅲ mRNA in cultured cells. Our results show that CTGF can directly induce myofibroblasts formation, and increase the level of Collagen Ⅲ mRNA. This suggests that CTGF may be a novel pharmacotherapeutical target protein for the interference with renal fibrosis, thus providing useful theoretic possibility for clinical prevention of chronic progression of kidney disease.展开更多
