Abstract

The invention discloses a method for promoting the healing of diabetic wounds by using hFDSPCs-CM and HA, combining the conditioned medium of dermal stem cells derived from foreskin and hyaluronic acid to promote the healing of diabetic wounds, and for the first time the dermal stem cells / progenitor cells derived from The conditioned medium combined with hyaluronic acid is applied to the diabetic mouse model. Compared with the currently widely used conditioned medium of adipose-derived stem cells, it has a better effect of promoting wound healing, especially in promoting collagen synthesis. Diabetic refractory wounds are of great significance, and the simple operation is expected to achieve clinical transformation in the future. The present invention provides relevant data that the conditioned medium of the foreskin-derived dermal stem / progenitor cells promotes the healing of diabetic wounds, and explores the relevant mechanism in in vivo and in vitro experiments.

Description

technical field [0001] The invention relates to a method for promoting diabetic wound healing by combined use of hFDSPCs-CM and HA. Background technique [0002] Diabetic wounds are a common clinical problem characterized by insufficient chemokines and vascularization, decreased fibroblast migration and proliferation, and abnormal inflammatory responses. Current conventional treatments for this problem include customized excipients, surgical debridement, negative pressure therapy, antibiotics, and hyperbaric oxygen therapy. However, nearly 50% of patients still cannot be cured by traditional treatment methods. [0003] In recent years, a large number of studies have proved that mesenchymal stem cells from various tissue sources can promote diabetic wound healing, such as: bone marrow, fat, umbilical cord blood and skin tissue. Although mesenchymal stem cells from different tissue sources have certain similarities, they have different characteristics in different microenvir...
