Effect of PEMF-induced conditioned medium (CM) on chondrocyte and MSC migration and proliferation. CM was derived from 2D cultured MSCs in response to 0 mT (CCM) or 3 mT (PCM) PEMF exposure. a Migration of chondrocytes or MSCs was analyzed using a transwell culture. Migrated cells were assessed by measuring the number of cells on the underside of the transwell filter after H&E staining. b Cell proliferation was determined by Picogreen DNA Assay. Data shown represent means ± SD, n = 6 from 2 independent experiments. * denotes significant difference compared to the negative control (Expansion media + 0.5% FBS); # denotes significant differences compared to positive controls (Expansion media + 10% FBS); @ denotes significant differences compared to the non-PEMFed CCM
