Primed CM from UC-MSCs promoted higher expression of tendon markers in vitro. A-B Representative images of cellular immunofluorescence staining of the COL I (green) and TNMD (red) (n = 5 per group). C-D Semi-quantitative analysis of the mean fluorescent intensity. TDSCs of the primed CM group expressed higher levels of COL I and TNMD than the unprimed CM group and control group. The nuclei were stained with DAPI (blue). Scale Bar = 200 μm. Data are presented as mean ± SD. **P < 0.01; ***P < 0.001.
