Diabetic Foot Ulcer, Umbilical cord blood mononuclear cells
Brief summary
Umbilical cord blood mononuclear cells (MNC) may improve the wound repair ability. This study aims to investigate the role of MNC in refractory diabetic foot ulcer by comparing the combination of PRP and MNC with PRP alone.
Detailed description
The difficulty in the healing of diabetic foot is related to the loss of local repair microenvironment. The platelet rich plasma (PRP) can improve the repair ability, however, the requirement for wound bed preparation is strict, or treatment failure may occur. Umbilical cord blood mononuclear cells (MNC) may provide a better repair environment through paracrine action. This study aims to investigate the role of MNC in refractory diabetic foot ulcer by comparing the combination of PRP and MNC with PRP alone.
Interventions
Local wound treatment by combination of PRP and MNC, once;
Local wound treatment by PRP alone, once.
