Fig. 3From: The inhibition of human lung fibroblast proliferation and differentiation by Gs-coupled receptors is not predicted by the magnitude of cAMP responseFibroblast proliferation. Concentration-dependent increase in HLF proliferation following treatment with serum or PDGF for 24 h, assayed using BrdU incorporation. Data were normalized to maximal proliferation observed with 10% serum, and expressed as mean ± SEM for 8 independent experimentsBack to article page
