Ionomycin-induced actin polymerization in U2OS cells - basal region.
U2OS cell expressing Ftractin-GFP (green) and mito-BFP (red), stimulated with 4μM Ionomycin at time 0 (sec). Confocal images acquired every 15sec at basal region. Box denotes the region in inset at right. Corresponds to Figure 1A. Scale bar: 10μm for whole cell and 5μm for inset.
