Fibroin-Gelatin Composite Stimulates the Regeneration of a Splinted Full-Thickness Skin Wound in Mice
- 9 Downloads
The effects of composite fibroin-gelatin microparticles (100-250 μ) on the rate of wound healing and regeneration under conditions of contraction prevention were studied on the model of splinted full-thickness skin wound in a mouse. Subcutaneous injection of these particles into the defect area accelerated wound healing and promoted re-epithelialization and recovery of normal structure of the epidermis. In addition, the composite microparticles promoted the formation of connective tissue of characteristic structure, replacing the derma over the entire defect, and stimulated regeneration of subcutaneous muscle (panniculus carnosus) and skin appendages (sebaceous glands and hair follicles).
