Stem Cell Educator Therapy in Type 2 Diabetes

February 16, 2012 updated by: University of Illinois at Chicago
Type 2 diabetes is the most common form of diabetes. The prevalence of diabetes has been markedly increased in recent years. More and more children and young adults develop this devastating disease. Despite of multiple factors (e.g., food, environmental, and genetic factors) contributing to the developing of diabetes, increasing evidence demonstrated that chronic inflammation and/or atuoimmunity are common issues and play key roles in the pathogenesis of type 2 diabetes, leading to the insulin resistance and the shortage of insulin-producing islet beta cells. Thus, anti-inflammation is becoming a novel approach for the treatment of type 2 diabetes. Evidence that multipotent stem cells derived from human cord blood (CB-SCs) can control inflammation and autoimmune responses by altering regulatory T cells (Tregs) and human islet beta cell-specific T cell clone in type 1 diabetes offers promise for a new approach to treat type 2 diabetes. Here, the investigators develop a novel Stem Cell Educator therapy by using CB-SC and explore the therapeutic effectiveness of Stem Cell Educator therapy in T2D patients.

Description

Inclusion Criteria:

  • Patients were screened for enrollment in the study if both clinical signs and laboratory tests meet the diagnosis standards of American Diabetes Association 2010. Other key inclusion criteria were presence of at least one autoantibody to the pancreatic islet β cells for the autoimmune-related type 2 diabetes.

Exclusion Criteria:

  • Exclusion criteria were any clinically significant diseases in liver, kidney, and heart. Additional exclusion criteria were no pregnancy, no immunosuppressive medication, no viral diseases or diseases associated with immunodeficiency.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Cord blood stem cell
Human cord blood-derived multipotent stem cells (CB-SC) display unique phenotypes, such as the expression of embryonic stem (ES) cell markers, multipotential of differentiations, very low immunogenecity, and immune modulations. Stem Cell Educator will be used for isolation and purification of cord blood stem cells for the treatment.
For the treatment, commonly the left (or right) median cubital vein, a patient's blood is passed through a Blood Cell Separator that isolates the lymphocytes from the blood according to the recommended protocol by manufacture; consequently, the collected lymphocytes were transferred into the Stem Cell Educator and treated by CB-SC; after that, the educated cells return the blood back to the patient via a dorsal vein of hand. During the MCS+ collection, the whole blood flow rate was maintained at 35 mL/min. The whole procedure was scheduled for 6 ~ 7 hrs.
