Figure 2From: A naturally occurring carotenoid, lutein, reduces PDGF and H2O2 signaling and compromises migration in cultured vascular smooth muscle cellsTime-dependent effect of lutein on PDGF-induced cellular signaling. PDGF-BB was preincubated with vehicle or lutein for 30 min and was added to VSMCs for the indicated time periods. After incubation, cells were harvested and lysates were analyzed by Western blotting (n = 3).Back to article page
