Stem cells from cord blood "re-taught" the immune system T-cells in type one diabetics so that their pancrei began to produce insulin, thereby reducing the amount of insulin they need to inject. Dr. Yong Zhao from the University of Illinois at Chicago published these findings online in an open access journal.
The researchers described a procedure that they called "Stem Cell Educator Therapy" where the diabetic patient's blood is circulated through a closed-loop system. The system separates lymphocytes (a class of immune cells that includes T cells) from the whole blood and cultures them with cord blood cells from healthy donors before returning the "re-educated" lymphocytes to the patient's blood stream.
