Strip and Cka control mitotic morphogenesis in cultured S2 cells. (A) Time lapse of cells stably coexpressing moesin-GFP (green) and α-tubulin-mCherry (red) treated as indicated and undergoing mitosis. (B and C) Percentage of cells with cortical instability in metaphase (B) or after metaphase onset (C) were quantified from live-cell recordings of four independent experiments (circles). Data are represented as mean ± SD of the pooled experiments, one-way ANOVA with the following P values: NS, P > 0.05; *, P < 0.05; **, P < 0.01. Scale bars, 5 µm.
