Wound healing effect of an Astragalus membranaceus polysaccharide and its mechanism.

In the present study, a novel polysaccharide, APS2-1, was isolated and purified from Astragalus membranaceus using DEAE-cellulose and Sephadex G-100 chromatography. The effect of APS2‑1 on the promotion of wound healing was evaluated and its preliminary mechanism was investigated. In vitro experiments showed that APS2‑1 was able to promote human skin fibroblast (HSF) propagation and accelerate cell cycle progression.
