Effect of PHBV scaffolds on wound healing and scarring at 28 days after treatment: (a–c) Mechanical properties of regenerated wounds: stress-strain curves (a), strain at break (b), and elastic modulus (c). For each group, three independent samples were used for the stress-strain measurements and one representative result was presented. (d) Expression of scarring-associated markers (α-SMA, TGF-β1, and TGF-β3) in regenerated wounds.
