Brief summary: To compare the efficacy and cost-effectiveness between purified CD34+ cells and peripheral blood mononuclear cells in treatment of critical limb ischemia


Eligibility criteria: Inclusion Criteria:

* Rutherford scale of 4-5
* thromboangiitis obliterans, peripheral arterial disease, or arteritis caused by other etiologies, such as collagen diseases
* surgical or endovascular procedures are considered unlikely to have successful long-term revascularization, or have failed
* more than 4 weeks of critical limb ischemia
* if present, a non-healing ulcer after more than 4 weeks of optimal care by a wound care physician and a nurse

Exclusion Criteria:

* within 3 months of an acute myocardial infarction
* any contraindication for the administration of granulocyte colony stimulating factor (G-CSF)
