Treatment with Hyaluronic Acid and Collagen-Polyvinylpyrrolidone Improves Extracellular Matrix Assembly for Scarring after Tracheal Resection

Figure 3

Collagen deposition in tracheal scars prior to surgery and at the end of the study. Each bar represents the of the collagen concentration in the tracheal tissue for each study group; (ANOVA and Tukey’s test). The reduced collagen depositions observed in the mixture of hyaluronic acid+collagen-PVP and mitomycin C groups vs. the control group are shown. Group I = control; group II = hyaluronic acid; group III = collagen-PVP; group IV = mixture of hyaluronic acid+collagen-PVP; group V = mitomycin C.
