Figure 7 (a) 3H-proline incorporation, an estimate of collagen synthesis, by neonatal rat cardiac fibroblasts cultured in the presence of TGF-ß1 and various concentrations of RWJ. (b) Northern blot analyses of 
1(I) procollagen gene expression relative to the housekeeping gene, GAPDH, in neonatal rat cardiac fibroblasts cultured in the presence of RWJ and TGF-ß1. n = 3 for each condition. Data are represented as mean ± SEM. *p < 0.05 versus unstimulated. 
p <0.05 versus TGF-ß1 stimulation alone.
