Fig. 5From: Exposure of primary osteoblasts to combined magnetic and electric fields induced spatiotemporal endochondral ossification characteristic gene- and protein expression profilesAlizarin red staining of hOBs after exposure to EFMF. Staining was quantified with an ELISA reader at 405 nm, and the results were normalized to the cell number detected in the exposure wells. n = 3, * = p < 0.05 compared to control cells (normalized on cell counts)Back to article page
