Eligibility criteria:
Inclusion Criteria:

Potential candidates must have type 1 diabetes mellitus and fulfill one or more of the following:

Manifest signs and symptoms that are severe enough to be incapacitating. Incapacitating signs and symptoms include hypoglycemic episodes requiring assistance by others and hypoglycemia unawareness (the inability to recognize low blood glucoses; glucoses < 54 mg/dl). These patients are at high risk for involvement in accidents (they can lose consciousness or act irrationally), thus causing harm to themselves and/or others.
Patients with poor diabetes control (HbA1c > 8.0% but < 12%), despite intensive insulin therapy, as defined by: self monitoring of blood glucose ≥ 4 times/day, multiple insulin injections (≥ 3/day) or insulin pump, and close monitoring of blood glucose control by an endocrinologist. These patients can experience acute, rapid hyperglycemia secondary to several stress factors, that can lead to dehydration, disorientation, and in some instances, ketoacidosis.
Progressive diabetic complications. These patients with chronically poor glycemic control are at higher risk for the development of a wide variety of complications (retinopathy, neuropathy, nephropathy, and cardiovascular disease) associated with diabetes.

Exclusion Criteria:

Potential candidates will be excluded as per the following criteria:

Age < 18 or > 65 years
Duration of diabetes < 5 years
Do not have a physician that is monitoring diabetes for > 6 months
Body mass index > 26
Weight > 80 kg
Insulin requirement > 1.0 u/kg/d
HbA1c > 12%
Stimulated or basal C-peptide > 0.3 ng/ml
Corrected creatinine clearance < 60 ml/min
Serum creatinine consistently above 1.6 mg/dl
Macroalbuminuria (> 300 mg/24 hours)
Anemia (hemoglobin < 12.0 g/dl for males; < 11 g/dl for females)
Hyperlipidemia (fasting low-density lipoprotein [LDL] cholesterol > 130 mg/dl and/or fasting triglycerides > 200 mg/dl)
Abnormal liver function tests (consistently > 1.5 x normal range)
Serological evidence of HIV, HBsAg and/or HBcAb, HBsAb without history of vaccination, human t cell lymphotropic virus 1 (HTLV-1), or hepatitis C virus (HCV)
Negative serology for Epstein-Barr virus (EBV) or evidence of acute or chronic infection (IgM ≥ IgG)
Lack of updated immunizations per current Centers for Disease Control (CDC) guidelines (including lack of immunization against hepatitis B, pneumococcus and influenza - during season)
Presence of panel reactive antibodies > 20%
Prostate-specific antigen (PSA) > 4 ng/ml unless malignancy is ruled out
Positive tuberculin test (unless proof of adequate treatment for latent tuberculosis can be provided)
X-ray evidence of pulmonary infection or other significant pathology
Gall stones and/or portal hypertension and/or hemangioma on liver ultrasound
Abnormal abdominal or pelvic ultrasound (evidence of masses that are considered suspicious for malignancy or adenopathy)
Active peptic ulcer disease
Active infections
Unstable cardiovascular status (including positive stress echocardiography if age > 35)
Untreated or unstable proliferative diabetic retinopathy
Previous/concurrent organ transplantation (except for failed islet cell or pancreas transplantation)
Malignancy or previous malignancy
Any medical condition requiring chronic use of steroids
Active alcohol or substance abuse; smoking in the last 6 months.

Sexually active females who are not:

post-menopausal,
surgically sterile, or
not using an acceptable method of contraception (oral contraceptives, Norplant, Depo-Provera, and barrier devices with spermicide are acceptable; condoms used alone are not acceptable)
Positive pregnancy test or intent for future pregnancy, or male subject's intent to procreate
Any condition or any circumstances that make it unsafe to undergo an islet cell transplant
Psychogenically unable to comply
Failed psychological evaluation
Persistent leukopenia (white blood cell count < 3,000/uL on more than 3 occasions)
