ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of recombinal human connective tissue growth factor (rhCTGF) stimulation on epithelial-myofibroblast transdifferentiation (EMT) and collagen-synthesis in human renal tubular epithelial cell line (HK2) in vitro.</p><p><b>METHODS</b>The cultured HK2 cells were stimulated with rhCTGF of 5 ng/mL. The morphological changes were observed under an inverted microscope. The cells were collected at 0, 3, 6, 12, 24 and 48 hrs after rhCTGF stimulation. The expression of E-cadherin,alpha-smooth muscle actin (alpha-SMA), collagen Ialpha1 (Col Ialpha1) and collagen IValpha1 (Col IValpha1) mRNAs were detected by RT-PCR.</p><p><b>RESULTS</b>rhCTGF stimulation changed the HK2 cell appearance from oval to fusiformdown-regulated the E-cadherin mRNA expression and up-regulated alpha-SMA mRNA expression, but had no effects the Col Ialpha1 and Col IValpha1 mRNA expression.</p><p><b>CONCLUSIONS</b>Exogenous CTGF can mediate the EMT but has no collagen-synthesis effects on HK2 cells.</p>
