PEMF accelerates the proliferation of HUVECs without significant toxicity. HUVECs were stimulated by PEMF for 1-4 cycles and the proliferation was analyzed by Cell Count Kit-8 (CCK-8) in several time point as indicated (A). The cell toxicity was also checked (B). Values are mean ± SEM; n = 4, N.S. means no significant difference, *means P < 0.05, **means P < 0.01, vs. control group.
