Figure 4From: Adipose-derived stem cells cooperate with fractional carbon dioxide laser in antagonizing photoaging: a potential role of Wnt and β-catenin signalingSurvival of ADSC. ADSCs were stained with DAPI and were directly injected in the skin of rat. Two weeks after injection, rat skin block was made using cryosection and counterstained with blue-fluorescent nucleic acid stain. ADSCs are stained blue (arrows indicate).Back to article page
