• Hemoglobin HbA1c ≤7.5%
• Able and willing to comply with the procedures required by the protocol. Patients may be managed as either inpatient or outpatient.
• If a female of childbearing potential, the subject must have a negative serum pregnancy test at screening

• Total abstinence from sexual intercourse (minimum of one complete menstrual cycle before study entry),
• A partner who is physically unable to impregnate the subject (e.g., vasectomized)
• Contraceptives (oral, parenteral, or transdermal) for 3 consecutive months prior to the patient's cell concentrate administration,

• Digits, head, genitalia, palms of hands, soles of feet, and face are excluded as test sites

• Venous or arterial vascular disorder directly affecting a designated test area
• Known immune deficiency disorder, either congenital or acquired
• Chronically malnourished as determined clinically by the investigator prior to surgery (Investigators are responsible for determining subjects are chronically malnourished during the screening process. Investigators should take into consideration the following parameters: medical history and physical appearance, the subject's body mass index, and any significant laboratory findings)
• Severe respiratory problems or concurrent head trauma at hospital admission, including inhalation injury requiring ventilatory support
• Any chronic condition requiring the use of systemic corticosteroids 30 days prior to study entry and anytime during the course of the study

• Concurrent participation in another clinical trial in which an investigational agent is used. (Subjects must not have been enrolled in another clinical trial within 30 days of enrolling in this trial)
• Females who are pregnant or nursing or intend to become pregnant during the duration of the study
• Burn wounds that occur over joints
• Patients with the following abnormal laboratory test levels:
• Stage 4 or greater chronic kidney disease (eGFR < 50 mL/min)
• Hemoglobin < 10 g/dL
• Thrombocytopenia < 100,000 platelets/µL
• Serum albumin level <2.5 g/dL or > 30 g/dL at time of screening
