Burn blister fluids in the neovascularization stage of burn wound healing: A comparison between superficial and deep partial-thickness burn wounds

Burn wound healing is a complex and dynamic process that involves the interaction between different cell types and mediators. Neovascularization is an imperative stage of wound healing and consists of not only angiogenesis but also adult vasculogenesis. A superficial partial-thickness burn (SPTB) heals within 2 weeks without scarring. A deep partial-thickness burn (DPTB), conversely, requires 2 weeks or longer to heal and requires an aggressive treatment to prevent hypertrophic scarring. Burn blisters on the skin are a hallmark of not only SPTB but also DPTB; however, the effect of burn blister fluids on the neovascularization in these types of burns has not been fully explored. To verify this effect, the role of different burn fluids and the angiogenic factors that modulate this process are currently under investigation.
