The purpose of this study is to determine whether umbilical cord Mesenchymal Stem Cells of treatment for diabetic foot is safe and effective in the management of diabetic foot ischemia, the therapeutic effect of stem cells is caused by improving blood circulation in ischemic limb which would in turn promote ulcer healing, prevent amputation of limb and relieve the Sevier pain of ischemia.

Primary Outcome Measures:
  • Angiographic evaluation of angiogenesis at ischemic limb [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • Pain [ Time Frame: 3 months ]
  • Ankle-Brachial pressure index [ Time Frame: 3 months ]
  • Wound healing (wound size, wound stage) [ Time Frame: 3 months ]
  • Walking distance [ Time Frame: 3 months ]

Estimated Enrollment: 50
Study Start Date: January 2011
Estimated Study Completion Date: July 2013
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: umbilical cord mesenchymal stem cells
Multiple intra muscular injection of mesenchymal stem cells derived from human umbilical cord.
Biological: umbilical cord mesenchymal stem cells
5*10/7 per ischemic limb
Other Name: mesenchymal stem cells
Active Comparator: Standard Therapy
Any therapy for diabetic foot which is routinely practiced and accepted in China
Drug: Standard Therapy
Any thing directed to improve blood perfusion in the limb example.Heparin,Antiplatelet agents etc
Other Name: Drug therapy

Detailed Description:
Type 2 diabetic patients with diabetic foot were enrolled and randomized to either transplanted group or control group. Patients in transplanted group received the stem cells treatment,Patients in control group received the standard treatment. After culture in vitro, umbilical cord mesenchymal stem cells should go through safety evaluation which include culture and check of pathogenic microorganisms (bacteria, mycoplasma, chlamydia, eumycete and viruses) of the cells medium and karyotype analysis of the mesenchymal stem cells. Only the safe cells were harvested and transplanted by multiple intramuscular injections into the impaired lower limbs. Follow-up index include: efficacy (pain,ulcer healing rate, lower limb amputation rate and ,ankle-brachial index,magnetic resonance angiography,electromyogram) and safety (infection of the injection site, fever, and tumour generation).
