Fig. 2From: Radial shockwave treatment promotes human mesenchymal stem cell self-renewal and enhances cartilage healingRadial shockwave stimulation promotes proliferation of MSCs in a dose-dependent manner. Trypan blue exclusion cell counting (a) and CCK-8-based cell proliferation assay (b) showed shockwave-treated MSCs exert stronger proliferative effects than control cells, and maximum cell viability occurred on the 11th day after stimulation. Optimal stimulation dose was 2 bars. Shockwave-treated MSCs incubated and measured at different pressures and compared with control groups in at least four independent experiments (different groups marked with different symbols). *Statistically significant difference compared with control group, P < 0.05Back to article page
