Figure 1From: A naturally occurring carotenoid, lutein, reduces PDGF and H2O2 signaling and compromises migration in cultured vascular smooth muscle cellsDose-dependent effect of lutein on PDGF-induced cellular signaling. PDGF-BB was preincubated with vehicle or the indicated concentrations of lutein for 30 min and was added to VSMCs for 10 min. Cells were harvested and lysates were analyzed by Western blotting (n = 4).Back to article page
