qRT-PCR analysis. qRT-PCR analysis of fibrogenic growth factors in B16 melanoma and C38 colon carcinoma cell lines. The relative expression levels (%) of Pdgfb, Ctgf, Fgf2 (a) and Tgf-β (b) were determined by comparing their expression levels to the expression level of GAPDH; the error bars display SD
