AIM: To investigate relevant factors of stem cell transplantation for treating diabetic foot. METHODS: Disposal, outcome, adjuvant method and safety during stem cell transplantation for treatment of diabetic foot were analyzed. RESULTS: ①After autologous stem cells were depurated at a low temperature for 24-48 hours, number of malignant stem cells decreased. Compared to simple stem cell transplantation, tissue regeneration and neovascularization increased after adding fibrin base during transplantation. ②Ankle-brachial index and transcutaneous oxygen pressure were obviously elevated, rest pain and intermittent lameness were improved, new collateral circulation appeared, and arterial blood flow increased in patients undergoing bone marrow stem cell transplantation in the treatment of ischemic disease of lower extremity. ③Chinese medicine for supplement- ing qi and activating blood circulation for stem cell transplantation fully played regulatory effects of biological responses. Adjuvant methods such as ultrasound ablation in combination of stem cell transplantation could significantly increase lower collateral circula- tion of broken popliteal artery. ④No significant adverse reaction or severe outcome was detected in autologous stem cell transplan- tation in a short term. CONCLUSION: ①Autologous stem cells after purified by low temperature can effectively purify malignant stem cells in bone marrow stem cell transplantation. Transplanted outcome can be elevated by adding fibrin. ②Adjuvant methods can enhance outcome of stem cell transplantation. ③Stem cell transplantation for treating diabetic foot has obtained satisfactory outcomes, but some problems still exist.
