Figure 2From: Stimulation of osteogenic differentiation in human osteoprogenitor cells by pulsed electromagnetic fields: an in vitro study Effect of PEMF stimulation on osteogenic differentiation of human BMSCs. Figure shows alkaline phosphatase activity (A) and calcium deposition in the extracellular matrix (B) of these cells. Cells were obtained from 4 differenent donors (n = 3 per donor). Significant differences due to PEMF are marked * (p < 0.05, Wilcoxon signed rank test).Back to article page
