Brief Summary
The purpose of this study is to measure the concentration of cells and proteins in the patient's blood during administration of Nuopogen (Filgrastim), a medication that is FDA approved for stem cell mobilization, in combination with a programmed pneumatic compression device (PPCD) (Art-Assist Device). The Art-Assist Device is an FDA approved device that promotes blood flow in the patient's legs. A patient will be prescribed this device and this drug to help improve the poor circulation in his/her leg. The use of Nuopogen along with the Art-Assist Device has not been approved by the FDA and is considered experimental. This study is not designed to find out how well the Art-Assist Device works, nor how well the drug works in mobilizing stem cells. Instead, it is a study of how well cells lining blood vessels in calf respond to increases in shear stress, and how well the increase in the population of certain cells in the blood stream effect how the new blood vessels will form. It is important for clinical reasons, and for the purposes of this study, that the patient uses the Art-Assist Device as prescribed on a daily basis as discussed with the patient's doctor

Outcome Measures
Primary Outcomes (1)
Measuring the pharmacologic increase in of CD31+ (mature endothelial cell)
Using the FACSaria sorter. Following clot formation (30 min) each tube will be centrifuged for 15 min at 1000g and the separated serum will be stored at -20° C. Protein will be measured using Enzyme-linked immunosorbent assays (ELISA).
4 months
Secondary Outcomes (3)
Measureing the pharmacologic increase in CD34+(progenitor cell),
4 months
Measureing the pharmacologic increase in VEGFR2+ (endothelial progenitor cell)
4 months
Pharmacologix measurement of nitrite
4 months
Study Arms (1)
AA and Neopogen
EXPERIMENTALPatient undergoes treatment with Art-assist device and Neupogen
Interventions
Neupogen is given as an injection in your skin every three days for a total of 5 doses.
The programmed pneumatic compression device (PPCD) is to be worn for a minimum of three hours daily while patient is sitting down
Eligibility Criteria
You may qualify if:
- Male or female between the ages of 40 and 85.
- Chronic limb ischemia Fontaine Class III (ischemic forefoot rest pain) and Class IV (non-healing ischemic ulcers, gangrene) with confirmatory non-invasive vascular testing.
You may not qualify if:
- Acute limb ischemia requiring emergency treatment.
- Non-salvageable foot (e.g. extensive gangrene, advanced infection, rigor mortis, knee/hip flexion contracture, post-stroke paralysis, and hemiparesis).
- Untreated hypercoagulability disorder, sickle cell anemia, myeloproliferative disorder.
- Dialysis, and sustained elevated Creatinine \> 4 mg/dl.
- Severe dementia; bed-ridden; non-compliance; unlikely to follow-up; unreliable.
- Intolerance of PPCD compression
- Morbid obesity (Body Mass Index \> 34)
- Severe venous insufficiency causing venous stasis ulceration and dermatitis.
- Uncorrected significant aorto-iliac, common femoral, and profunda femoral arterial disease
- Ulceration precluding PPCD placement.
- Active cancer.
- Allergy to Nuopogen.
