Figure 8. Representative frozen cross-section of a wound treated with the completed medium-infused peptide hydrogel after Masson’s trichrome staining on day 14.

Collagen is stained blue. Collagen deposition was denser near the wound edge and in the deeper tissue layers, indicative of the inwards and upwards progression of wound healing. There was no obvious difference between the treatment groups in terms of density and location of collagen deposition.
