  • Publication number: 20250000911
    Abstract: The present disclosure discloses an autophagosome for promoting healing of a diabetic wound, and a preparation method and use thereof. In the preparation method of the autophagosome provided in the present disclosure, the autophagosome is extracted from a starved vascular endothelial cell, and the production of the autophagosome does not require induction by an additional reagent. The preparation method of the present disclosure involves simple extraction conditions, does not require an ultracentrifuge, and can be implemented in an ordinary laboratory. In addition, a yield of the autophagosome is higher than a yield of an exosome. The present disclosure provides an easy-to-implement and low-cost treatment method without toxic and side effects for a patient suffering from a chronic refractory wound. The autophagosome of the present disclosure can promote healing of a diabetic wound, and reduce physiological and psychological burdens caused by a diabetic wound to a patient.

  • Publication number: 20250002911
    Abstract: The present disclosure belongs to the technical fields of genetic engineering and biotherapeutic drugs, and relates to an engineered exosome for treating hypertrophic scar (HTS), and a preparation method and use thereof. In the present disclosure, the engineered exosome for treating HTS is a mesenchymal stem cell (MSC)-derived exosome overexpressing miR-141-3p. The exosome can significantly reduce formation of the HTS.

  • Publication number: 20250000807
    Abstract: The present disclosure provides a circCDK13-enriched engineered small extracellular vesicle (E-sEV), and a preparation method and use thereof, and belongs to the technical field of biomedicine. The present disclosure provides a preparation method of the circCDK13-enriched E-sEV. In the present disclosure, human placenta-derived mesenchymal stem cells (hP-MSCs) are infected with a vector overexpressing circCDK13, and a resulting cell supernatant is collected to obtain a small extracellular vesicle (sEV) overexpressing the circCDK13, which is used for wound healing in diabetes mellitus (DM). The E-sEV shows a therapeutic effect on DM wounds that is significantly better than that of natural small extracellular vesicles (N-sEVs) secreted by the hP-MSCs. This product not only exhibits advantages in healing speed, but also has a greater application potential in stimulating skin appendage regeneration and improving the quality of wound healing.
