Fluorescent images of calcein stained A2780/A2780cis cells. The cells were incubated at 37 °C and stained with calcein, where live cells appear as green fluorescence (a). Quantitative analysis of fluorescence from calcein-positive cells (green) for A2780 (b) andA2780cis (c). Green fluorescence intensity was calculated by using ImageJ. All images have been taken at 100 × magnification; the scale bar is equal to 100 μm. The field of vision was randomly selected for all the samples. (*p-values < 0.05).
