Figure 4. ECA109 and TE13 cytoskeleton and microfilament structures. After QGS stimulation, isotropic arrangement of microfilaments was enhanced in ECA109 and TE13 cells; microfilament arrangement was disordered in the control group. In addition, microfilament arrangements were more regular and numbers of pseudopods were reduced after 200 μg/mL of QGS. Scale bars indicate 10 μm.
