Wound healing progression. At the site of skin wounding, granulation tissue developed. This reaction aims to initiate neovascularization to supply blood derived factors as well as oxygen and nutrients, to regenerate epithelium. During granulation development accompanied with deposition of collagen fibers, granulation tissue acts as a scaffold for cell migration and proliferation. Newly formed vessels derived from the fascia and/or EPCs migrate in an upward direction in the granulation. Connected vessels finally reach the site at which epithelial regeneration take place. This process advances in the order of no treatment < cryogel alone < cryogel plus GF/C as demonstrated in the present study.
