Abstract

Natural medicine can be used to develop wound healing agents due to its excellent characteristics of promoting rapid wound healing. Pine pollen Polysaccharides (PPPS), a water-soluble polysaccharide with hydrophilicity and viscosity, which is suitable for the development of wound dressing. The purpose of this study is to explore the role and mechanism of PPPS in the process of wound healing. The results showed that PPPS could accelerate the wound healing, promote cell proliferation, transform the cell cycle from G1 phase to S and G2 phase, and increase the expression of Cyclin B1 in vitro. These effects of PPPS were achieved by activating JAK2-STAT3 signaling pathway. Similarly, PPPS could accelerate the healing of mouse cutaneous wounds, and could promote the growth of chicken embryo chorioallantoic vessels. In conclusion, this study indicates that PPPS is a new promising natural agent for promoting wound healing.
