The effect of different frequencies of electromagnetic fields (EMF) on migration of human bone marrow-derived MSCs. a The migration ability of human BM-MSCs after stimulations with 7.5, 15, 30, 50, and 75 Hz/1 mT EMF examined using the transwell migration assay. Migrated cells on the bottom surfaces of the transwell inserts were stained with crystal violet and observed under a microscope (100×). b Quantitative results of cell migration. Data are presented as means ± SD. Statistically significant differences are indicated; n = 3; *p < 0.05, **p < 0.01, vs control or as indicated
