Summary

Alopecia Areata (AA) is one of the most common T cell-mediated autoimmune diseases, leading to the chronic and relapsing hair loss. The prevalence of AA worldwide is 0.1 to 0.2%, affecting an estimated 5.3 million people in the United States. To date, the clinical therapies are limited and disappointed for the treatment of AA. Alternative approaches are needed. Increasing evidence demonstrates that stem cells possess the function of immune modulation. We established the Stem Cell Educator therapy by using cord blood-derived multipotent stem cells (CB-SCs)(Zhao Y, et al. BMC Medicine 2012). A closed-loop system that circulates a patient's blood through a blood cell separator, briefly co-cultures the patient's lymphocytes with adherent CB-SCs in vitro, and returns the educated lymphocytes (but not the CB-SCs) to the patient's circulation. Our clinical trial reveals that a single treatment with the Stem Cell Educator provides lasting reversal of autoimmunity that allows regeneration of islet beta cells and improvement of metabolic control in subjects with long-standing type 1 diabetes (T1D), which is another most common T cell-mediated autoimmune disorder in the United States. Here, we develop and explore the therapeutic effectiveness of Stem Cell Educator therapy in AA patients.

DEVICE

Stem Cell Educator

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 8 \~ 9 hrs.
