(a) Plot of the cell protrusion creep compliances as a function of the incubation time in OTC: control (untreated cells) (black curves), 24 h (red curves), 48 h (blue curves); (b) averaged curves of the Log-Log plots of the behaviors in a). The red continuous lines are the fit with the power-law relation. (c) Statistical analysis of the value of the α- exponent corresponding to different incubation times in OTC (control, T24-24 h; T48-48 h) (mean ± SEM). In the case of control vs T48 we obtain **p < 0.01 (Kruskal-Wallis test). (d) Statistical analysis of the value of the stiffness parameter corresponding to different incubation times in OTC (control, T24-24 h; T48-48 h) (mean ± SEM). In the case of control vs T48 we obtain *p < 0.1 (Kruskal-Wallis test).
