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

Figure 5 Analysis of collagenization in skin wounds. A: Inference of collagen amount (collagenization); B: Photomicrograph of histological sections of skin wounds from Carbopol, platelet-rich fibrin (PRF), PRF + CaCl₂, and platelet-rich plasma groups, at D3, D7, D14, and D21. TM staining, 100 × magnification. ^aP < 0.05 vs the Carbopol group. ^bP < 0.05 vs the platelet-rich fibrin group. ^cP < 0.05 vs compared to the Carbopol and platelet-rich fibrin + CaCl₂ groups. ^dP < 0.05 vs the platelet-rich fibrin + CaCl₂ group. ^eP < 0.05 vs the Carbopol and platelet-rich fibrin groups. One-way analysis of variance followed by Tukey's test. Error bars: Standard error of the mean. PRF: Platelet-rich fibrin; PRP: Platelet-rich plasma.
