Research progress of adipose derived stem cells in wound healing / 国际生物医学工程杂志

ABSTRACT

Skin is a kind of tissue that surrounds the surface of body, it is the first barrier for animals to resist mechanical, chemical and pathogenic microorganisms. Skin wound is one of the most common surgical diseases. The process of wound healing can be summarized as three stages inflammation stage, fibrous tissue proliferation stage, and scar formation and repair stage. Incomplete repair of the wound leads to skin scarring, which causes the tissue to lose its normal structure and function, and seriously affects the aesthetic appearance. Traditional treatment methods can not restore the normal function of the skin and have obvious adverse reactions, which can not meet people's needs. Stem cell therapy, especially adipose derived stem cells (ADSCs) plays a essential rule in the process of wound healing making it a research hotspot in recent years. ADSCs can secrete a variety of growth factors during wound healing to reduce wound inflammatory response, promote wound regeneration epithelialization and vascular reconstruction, thereby promoting wound healing. In this paper, the wound healing process and its regulation mechanism were summarized, and the role of ADSCs in wound healing at home and abroad and its clinical application progress were reviewed.
