Effects of the different cell therapy products. (a) Dermal, epidermal and total skin thicknesses were measured (μm). Data presented as mean ± standard deviation (n = 6, six measures/mouse). (b) Graphic representation of the total skin thickness (*P <0.05, **P <0.01). White, healthy skin (no bleomycin (BLM), no treatment); grey, sclerosis control (BLM, no treatment); dark grey, injection control (BLM + sodium chloride (NaCl)); black, treatments (BLM + cell therapy products). (c) Corresponding histology. Bars = 500 μm. MF, micro-fat; PRP, platelet-rich plasma; SVF, stromal vascular fraction.
