A Clinical Study Using Adipose-derived Stem Cells for Diabetic Foot

Phase 1

• Conditions: Peripheral Vascular Disease; Diabetic Foot; Ischemia
• Interventions: Biological: saline; Biological: Adipose-derived stem cell

• Registration Number: NCT02831075
• Lead Sponsor: Jie Shen

Brief Summary

Stem cell therapy has been a new and effective therapy in recent years for diabetic foot.This study intends to establish an optimal clinical research program, and attempts to break the technical bottleneck in the stem cell therapy for treating diabetes related vascular complications.

Detailed Description

Diabetic foot is one of the most serious chronic complications of diabetic patients, and still lacking effective treatments.

Stem cell therapy has been a new and effective therapy in recent years for diabetic foot. Combined with the previous studies of our research group, this study intends to transform part of the results of this research, establish an optimal clinical research program, and attempts to break the technical bottleneck in the stem cell therapy for treating diabetes related vascular complications.
