Insulin dose and metformin doses should be stable over the 3 months prior to randomization. * HbA1c ≥ 7.5 and ≤ 9.5% at time of randomization. * Total insulin daily dose (TDD) at time of randomization should not exceed 1.0 units/day/kg Exclusion Criteria: * BMI \>35 kg/m2. * Insulin requirements of \> 100 U/day. * HbA1c \>9.5%. (at the time of randomization) * C-reactive protein (hs-CRP) \>3.00 * Uncontrolled blood Pressure: SBP \>160 mmHg or DBP \>100 mmHg at the time of randomization. * Evidence of renal dysfunction, serum creatinine \> 1.5 mg/dl (males) and 1.4 mg/dl (females). * Proteinuria \> 300 mg/day * Evidence of cardiovascular disease, existing congestive cardiac failure on physical exam and/or acute coronary syndrome in past 6 months. * For female participants: Positive pregnancy test, presently breast-feeding, or unwillingness to use effective contraceptive measures for the duration of the study.For male participants: intent to procreate 3 months before or after the intervention or unwillingness to use effective measures of contraception. Oral contraceptives,Norplant®, Depo-Provera®, and barrier devices with spermicide are acceptable contraceptive methods; condoms used alone are not acceptable * Active infection including hepatitis C, HIV, or TB as determined by a positive skin test or clinical presentation, or under treatment for suspected TB. Positive tests are acceptable only if associated with a history of previous vaccination in the absence of any sign of active infection. Positive tests are otherwise not acceptable, even in the absence of any active infection at the time of evaluation * Known active alcohol or substance abuse including cigarette/cigar smoking * Baseline Hgb below the lower limits of normal at the local laboratory; lymphopenia (\<1,000/L), neutropenia (\<1,500/L), or thrombocytopenia (platelets \<100,000/L). * A history of Factor V deficiency or other coagulopathy defined by INR \>1.5, PTT\>40, PT \>15. * Any coagulopathy or medical condition requiring long-term anticoagulant therapy(e.g., warfarin) after transplantation (low-dose aspirin treatment is allowed) or patients with an INR \>1.5. * Acute or chronic pancreatitis. * Symptomatic peptic ulcer disease. * Hyperlipidemia despite medical therapy (fasting LDL cholesterol \>130 mg/dl, treated or untreated; and/or fasting triglycerides \> 200 mg/dl). * Receiving treatment for a medical condition requiring chronic use of systemic steroids. * Symptomatic cholecystolithiasis. * Use of any investigational agents within 4 weeks of enrollment. * Admission to hospital for any reason in the 14 days prior to enrollment (signing consent). * Presence of active proliferative diabetic retinopathy or macular edema * Any malignancy * Abnormal liver function \>1.5 x ULN * Abdominal aortic aneurysm * History of cerebro-vascular accident * Any patient with acute or subacute decompensation from diabetes * Any acute or chronic infectious condition that in the criteria of the investigator would be a risk for the patient. * Subjects with hypoproteinemia, cachexia or terminal states * Subjects with history of anorexia/bulimia * Subjects with respiratory insufficiency * Subjects that are being treated with any medication that could interfere with the outcome of the study such as: Sulfonylureas, Thiazolidinediones and glucagon like peptide 1 (GLP-1) analogues (Exenatide, Byetta), Pramlintide (Amylin), Dipeptidylpeptidase IV (DPP-IV) inhibitors (i.e. Sitagliptin, Januvia) * Any medical condition that, in the opinion of the investigator, will interfere with thesafe completion of the trial.
