Immunofluorescence results of tubulins (a-f, red) and myosin II (g-l, red) and DNA (blue) of HeLa cells. Normal HeLa cells were taken as the control (a, b, g, h). The timing when the reversed cells were just back to isotonic DMEM culture was taken as time point 1, then 40 min after was taken as time point 2. The symbol “*” represents results of binuclear cells and “**” represents results of resuming-to-divide cells. Scale bar = 20 μm.
