The role of estrogenic substances in regulations of biological processes involved into wound healing

Wound healing is a physiological process that involves several successive and often overlapping phases that lead to the restoration of the integrity of the skin after an injury, accident or surgery: Haemostasis and inflammation, proliferation and remodeling. The interruption or slowing down of these processes can cause abnormal or impaired wound healing. There are now numerous data and clinical studies that highlight the role of estrogens on normal cutaneous homeostasis and wound healing. In postmenopausal women, for example, the reduced rate of wound healing processes has been clearly related to estrogen deficiency, especially in relation to inflammation and re-granulation, while treatment with exogenous estrogens can reverse these effects. We report here the complex role of estrogens and estrogenic derivatives in wound healing process, with a focus on their therapeutic use, and which strategies have been explored to find substances with poor systemic effects. © 2020 by Nova Science Publishers, Inc.
