Effect of Alcohol Extract of Spore Powder of Lasiosphaera Calvatia on Wound Healing of Full-thickness Skin Defect in Mice
To compare the effect of different solvent extracts of spore powder and fruiting body of Lasiosphaera Calvatia on fibroblasts and wound healing of full-thickness skin defect, in order to screen the optimal medication part of Lasiosphaera Calvatia.
Method
2
The effect of water extract and alcohol extract of spore powder and fruiting body on cell proliferation and cell migration of mouse skin fibroblasts (MSF) were examined
in vitro
. Cell proliferation and activity test (CCK-8) method was used for cell proliferation, scratch assay was used for cell migration, flow cytometry was conducted to explore cell cycle, enzyme-linked immunosorbent assay (ELISA) was used to determine the production of collagen Ⅰ and Ⅲ. At the same time, a full-thickness skin defect wound model was established to investigate the therapeutic effect of different solvent extracts of spore powder. Ultraviolet-visible spectrophotometry was used to measure the contents of index components in different solvent extracts.
Result
2
The water extract of spore powder and fruiting body had certain cytotoxicity, while the alcohol extract could promote proliferation, migration and production of collagen Ⅰ and Ⅲ of MSF, and the effect of spore powder was significantly higher than that of fruiting body. When the concentration was 10 mg·L
-1
, the cell proliferation rate of alcohol extract of spore powder was as high as (159.22±15.95)%, and could promote MSF from the G
0
/G
1
phase to S phase and G
2
/M phase with an increased proliferation index. The alcohol extract also promoted the migration of fibroblasts, secreted collagen Ⅰ and Ⅲ. On
in vivo
model, the alcohol extract of spore powder significantly accelerated wound healing on mice, effectively promoted the complete epithelialization of wound tissue, and generated new collagen fiber. The results of determination showed that the contents of polyphenols and flavonoids in the alcohol extract were higher than the alcohol extract of fruiting body.
Conclusion
2
The alcohol extract of spore powder in Lasiosphaera Calvatia has active components in the treatment of wounds with good development prospect, and the medicinal components may be polyphenols and flavonoids.
