CGF and umbilical cord mesenchymal stem cell exosome mixture, preparation and application

The invention discloses a CGF and umbilical cord mesenchymal stem cell exosome mixture, a preparation method and application of the mixture in skin injury repair. Umbilical cord mesenchymal stem cellexosomes are used as a seed component, CGF is used as a fertilizer component and a preservative component at the same time, the components are mixed and guided into injured skin tissue in a proper mode to jointly act on injured skin, the injured skin is repaired, the seed effect of the umbilical cord mesenchymal stem cell exosomes is further brought into full play through the fertilizer effect andthe preservative effect of the CGF, and finally the effect that the repair speed of the injured skin is obviously higher than that of the injured skin repaired by the exosomes independently through cooperation of the exosomes and the CGF is achieved. 本发明公开了一种CGF和脐带间充质干细胞外泌体混合物、制备方法及其在皮肤损伤修复中的应用，通过将脐带间充质干细胞外泌体作为"种子"组分、CGF同时作为"肥料"组分和"防腐剂"组分混合，以适当的方式导入受损皮肤组织中，共同作用于受损皮肤，对受损皮肤进行修复，通过CGF的"肥料"作用和"防腐剂"作用进一步充分发挥脐带间充质干细胞外泌体的"种子"作用，
