EdU-labeled OLP-MSCs and paeoniflorin-pretreated OLP-MSCs in skin tissues. Tissues were harvested on the 3rd day and stained with EdU (red fluorescence) and DAPI (blue fluorescence). (a) The EdU- and DAPI-stained images were digitally merged. Four representative tissues at 400 × magnification. (b) Quantification of EdU-labeled OLP-MSCs and paeoniflorin-pretreated OLP-MSCs. (c) Magnified images of the nuclei indicated by arrowheads in the graphs in panel (a). Scale bar = 50 μm. **P < 0.01. PF, paeoniflorin.
