Figure 5From: Stimulation of osteogenic differentiation in human osteoprogenitor cells by pulsed electromagnetic fields: an in vitro study Effect of PEMF on OPG/RANKL expression ratio in human BMSCs. Gene expression ratios of OPG/RANKL plotted as expression in PEMF-treated condition relative to non-treated control. Significant differences due to PEMF are marked * (p < 0.05), n = 4.Back to article page
