Fig. 4From: Deficiency of αII-spectrin affects endothelial cell–matrix contact and migration leading to impairment of angiogenesis in vitroSpectrin depletion modifies focal points in endothelial cells. Focal points were analyzed using monoclonal antibodies directed against vinculin (red) and polyclonal antibodies directed against αII-spectrin (green) on HMEC-1 cells and HUVECs 72 h after transfection with Sp siRNA or Nr siRNA. Spectrin-depleted cells exhibited a reduced number of focal points compared to Nr siRNA-treated cells. Scale bar = 20 μmBack to article page
