The micropipette aspiration measurements of artificial and real cells. (a) The micrograph shows micropipette aspiration of an artificial cell. Panels (b), (c), and (d) show the measurements of artificial cells with 5 μM actin, 10 μM actin, and 5 μM actin + 5 μM dynacortin, respectively. Panels (e), (f), (g), and (h) show micropipette aspiration measurements for WT, myosin II null, myosin II null + 2 μM latrunculin-treated, and myosin II::dyn-hp + 2 μM latrunculin-treated Dictyostelium cells. n > 8 for all cases. The converted Young's moduli are provided in Table TABLE I..
