Bioactivity of dressings based on platelet-rich plasma and Platelet-rich fibrin for tissue regeneration in animal model

Figure 1 Evolution of skin wound closure on D3, D7, D14, and D21. A: Skin wound area (cm²); B: Representative image of the visual wound area; C: Wound contraction rate. Results are presented as the mean ± SEM for 8 animals per group. ^aP < 0.05 vs the Carbopol group. ^bP < 0.05 vs the platelet-rich fibrin group. ^cP < 0.05 vs the platelet-rich fibrin + CaCl₂ group. One-way analysis of variance followed by Tukey's test. Error bars: Standard error of the mean. Bar = indicates image scale (1 cm). PRF: Platelet-rich fibrin; PRP: Platelet-rich plasma.
