[Adipose-derived stem cells in the proliferation phase of the healing process in cold burns] (original) (raw)

2021

Abstract

Cryosurgery has been used to treat different diseases of systems and organs, although adverse effects have been reported such as delayed wound healing, large scars, esthetical deformation and functional impairment. Injuries caused naturally by the exposure to extreme cold weather conditions mostly result in gangrene. This study aims to evaluate the influence of adipose-derived stem cells (ADSCs) in the proliferation phase on cutaneous wound healing. Through the application of liquid nitrogen by the spraying technique, a 15 millimeter diameter lesion was produced in the dorsal region of each rat. The wound received treatment according to the group it belonged: 1) ADSCs application on the 15th day (treated group); 2) application of 0.9% sodium chloride solution on the 15th day (sham group); 3) no intervention until euthanasia (control group). The group treated with ADSCs showed the highest wound average contraction rate; this group got a significant statistical difference in relation ...
