Induction of CTGF expression in HTM cells treated with various physiological agonists. A: RT-PCR results for CTGF expression after treatment of HTM cells with various physiological agonists for a period of 4 h. B: β-actin was amplified as an internal control, using the same RT libraries described in A. C: Relative densitometric readings based on two independent experiments are shown in the bar graph.
