Radial shockwaves promote colony-forming unit fibroblast formation of MSCs. a Comparisons of colony-formation efficiency. b Transformed data prepared using ImageJ software. Cell number in each subgroup shown above. When cell number is 1 × 10³ cells, there was no significant difference among the groups. There was a slight difference when cell number is 5 × 10³ cells. However, there is a significant difference when cell number is 1 × 10⁴ cells; the 2 bars group showed the highest colony-formation efficiency. CFU-F formation assay performed at least three times independently; representative data from a single experiment shown. **Statistically significant difference compared with control groups, P < 0.001
