Oxidative stress-induced cellular senescence desensitizes cell growth and migration of vascular smooth muscle cells through down-regulation of platelet-derived growth factor receptor-beta

Figure 2. Influence of cellular senescence on the proliferative and migratory capacities of A10 cells. Senescence was produced in cells by a 72-hr incubation with 300 μM CoCl2. After that, platelet-derived growth factor (PDGF)-BB-stimulated cell proliferation and migration were respectively analyzed by an MTT assay (A) and wound-healing analysis (B). * p < 0.05 compared to the normal cell group.
