Fig. 3From: Extremely low frequency electromagnetic fields promote mesenchymal stem cell migration by increasing intracellular Ca2+ and activating the FAK/Rho GTPases signaling pathways in vitroThe effect of electromagnetic fields (EMF) on the proliferation of MSCs. MSCs were stimulated with different frequencies of EMF (7.5, 15, 30, 50, and 75 Hz/1 mT) for 24 h. Cells cultured under normal conditions served as the baseline. The proliferation rate of MSCs following stimulation was evaluated using the MTT assay. Data are presented as means ± SD. n = 3. OD, optical densityBack to article page
