Figure 2

Global mechanical parameters extraction from FICs. FICs collected on two distinct (non interacting) myoblasts (left and right column) are shown. (a,b) Load (red) and unload (green) FICs and their parabolic fitting curves corresponding to global (G g , blue) and initial (G i , black) shear moduli. (c,d) Square root of the FICs and their linear fits with \(\sqrt{\frac{4\,\tan \,\theta }{\pi (1-\nu )}{G}_{g}}(Z-{Z}_{c})\) and \(\sqrt{\frac{4\,\tan \,\theta }{\pi (1-\nu )}{G}_{i}}(Z-{Z}_{c})\). (e,f) Temporal evolution of the work integral ratios D l  = (W l  − W u )/W l , W l /W i and W l /W g during 30 successive load-unload indentations on each cell.
