Overview of Stem Cell Educator therapy. A T1D participant (left) is connected to a Blood Cell Separator (right) and the Stem Cell Educator (bottom center) to form a closed system. Lymphocytes isolated from the T1D participant by the Blood Cell Separator travel through the Stem Cell Educator where they come in contact with CB-SCs attached to the interior surfaces of the device. Educated lymphocytes are returned to the patient's blood circulation. CB-SCs, cord blood stem cells; T1D, type 1 diabetes.
