Figure 4

Experimental measurement of the total amount of stress-fibers in human mesenchymal stem cells as a function of the substrate rigidity. The figure shows the total myosin content that scales with the mean-dipole strength, p = 〈pxx + pzz〉, and the corresponding elements, 〈pxx〉 and 〈pzz〉, calculated from S and p, see text. Theory curves obtained from the expansions of S and p (cf. Eq. 10) are shown to guide the eye (dashed curves).
