Four sets of cells are reported: normal C2C12 myoblasts, myotubes differentiated from C2C12 myoblasts, ATP depleted C2C12 myoblasts, and blebbistatin treated C2C12 myoblasts. The means are computed over all the FICS, and the uncertainties of these mean values correspond to the error of the mean, i.e. the ratio of the standard deviation by the square root of the number of cells, considering that each cell gives an independent measure. For comparison with other published works we also give the global Young modulus 〈Eg〉 = 3〈Gg〉 (assuming that the Poisson coefficient ν = 0.5). (See the Section Methods).
