[The effect of nicardipine on angiogenesis in vitro].
We studied the effect of nicardipine, a calcium channel blocker, on the morphological change of endothelial cells in vitro. Cultured endothelial cells derived from bovine carotid artery make tubular structures between collagen gel layers. Tube formation of endothelial cells was suppressed by culture with 10(-9)-10(-5) M of nicardipine in a dose dependent manner. Migration of endothelial cells was also suppressed by the same dose of nicardipine. However, proliferation of endothelial cells was not enhanced. These findings suggest that nicardipine acts as an inhibitor of angiogenesis in vitro by inhibiting the migration of endothelial cells.
