简要总结
This is a phase II single-blinded study to evaluate the efficacy and safety of ALLO-ASC-DFU in patients with Diabetic Foot Ulcer, compared to standard therapy.
详细描述
ALLO-ASC-DFU is a hydrogel sheet containing allogenic adipose-derived mesenchymal stem cells. Adipose-derived stem cells have anti-inflammatory effect and release growth factors such as vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF), which can enhance wound healing and regeneration of new tissue, finally may provide a new option in treating a Diabetic Foot Ulcer.
