2. Diagnosis of diabetes mellitus (type I or II) adequately controlled.
3. The ulcer is greater than 4 weeks duration.
4. Three or fewer ulcers separated by \> 3.0 cm distance.
5. Post-debridement, the ulcer size must be between 1 and 10 sq cm2.
6. Ankle/brachial index is between 0.7 to 1.2 and or one of the following must be present:

* transcutaneous partial pressure oxygen (TcPO2) \> 30 mmHg at the ankle
* toe pressure of \>40mm Hg or a Doppler waveform consistent with adequate flow in the foot (biphasic or triphasic)
7. At least 18 years old.
8. Able and willing to provide a voluntary written informed consent.
9. Able and willing to wear an off-loading orthopedic shoe.

2. Ulcer with exposed tendon or bone.
3. Gross clinical infection at the study ulcer site including cellulitis and osteomyelitis.
4. Gangrene.
5. Active Charcot's disease as determined by clinical and radiographic examination.

11. Severe liver disease as defined by the treating physician or patient's primary care physician.
12. Malignancy at or near the ulcer site.
13. Any condition judged by the investigator that would cause the study to be detrimental to the patient.
14. Presence of a hematology, clinical, chemistry or other test obtained within 7 days of screening that is outside the normal range for the laboratory and is determined to be clinically significant by the investigator.
15. Received another investigational device or drug within 30 days of Day 0.
16. Radiation therapy, chemotherapy or immunosuppressive therapy within 30 days of enrollment.
17. Received another allograft, autograft or xenograft within 30 days of the Day 0.
