Effect of CGP 53716 on growth factor-induced DNA synthesis in cultured RASMC and balb/3T3^1-a

Growth Factor	RASMC IC₅₀ (μM)	Balb/3T3 IC₅₀ (μM)
PDGF-BB	0.23 ± 0.01	0.17 ± 0.02
bFGF	0.43 ± 0.07	1.10 ± 0.31^1-b
EGF	0.79 ± 0.42^1-b	0.70 ± 0.11

↵1-a Values are mean ± S.E.M. of three to eight experiments.
↵1-b P < .05 vs. PDGF-BB within a cell type.
