Wound Healing
Wound healing is a natural reaction to tissue injury. For a wound to heal, four phases must occur in the right time frame: hemostasis, inflammation, proliferation, and remodeling.
This process involves an intricate interplay between several cell types, cytokines, mediators, and the vascular system.

Wounds generally heal in about a month in otherwise healthy individuals. However, in certain conditions, wounds may take much longer to heal and lead to chronic wounds that may persist much longer time frames, not completely heal, and even lead to advanced side effects such as sepsis and amputations.
Non-healing chronic wounds affect about 3 to 6 million Americans.
