(a) RICM images of two representative PatuS and PatuT cells. For the FD calculation the image of the whole cell area is used. (b) Histograms of the fractal dimension for both cell lines. The data could be fitted with a Gaussian curve. The FD of PatuT cells is significantly (p < 0.001) higher than that of PatuS cells (NPatuT = 86, NPatuS = 93 cells).
