STSV2 infection induces cell gigantism. Differential interference contrast (A) and scanning electron microscopy analysis (B) of noninfected and STSV2-infected REY15A cells. (Scale bars, 2 μm in A and 1 μm in B.) (C) Size distribution of the STSV2-infected REY15A cells during different time points after infection. The numbers above the plots represent median diameters of cells for each time point. Cell cultures were sampled at the indicated time points and the diameters of 600 cells from two independent experiments were measured for each time point using ImageJ (NIH).
