Effects of temperature and cytochalasin D on the instantaneous and equilibrium Young's modulus of hMSCs. The stiffness of hMSCs decreases with increasing temperature and increasing concentration of cytochalasin D. *p < 0.001 as compared to control. (1) p < 0.05 as compared to cytochalasin treatment at 0.2 μM. (2) p < 0.05 as compared to cytochalasin treatment at 2.0 μM. (3) p < 0.05 as compared to cytochalasin treatment at 20 μM. (4) p < 0.05 as compared to cells at 37°C.
