Figure 7


Fig. 7. Bead position vs time for simulations of the phagocytosis of a 3.2 µm bead. Solid lines correspond to cytoskeleton-membrane repulsion models, dashed lines to cytoskeletal swelling models. For each model, the flattening force was varied by ±33% around the best fit (thick line). Notice the strong dependence of the bead-trajectory in the cytoskeleton swelling model. Notice also that, for the best fit in this model, the shape of the cell at 20 seconds shows a phagocytic cup of excessive thickness compared with observations.
