Stem cell educator

The stem cell educator: lymphocytes isolated from a diabetes type 1 patient (blue color) by blood cell separator are transferred into the device at top right and come into contact with CB-SCs (green color) inside the device. Educated lymphocytes are returned for circulation at bottom left.

The stem cell educator is a device that is claimed to change or "re-educate" the behavior of human immune cells by placing the subjects cells in close proximity to stem cells, so as to alleviate or cure certain autoimmune diseases.

Device

Cord blood-derived multipotent stem cells (CB-SCs) are isolated from human cord blood[1][2] and act as educators for the patient's immune cells in the chamber. The hydrophobic material from (USP Class VI) plastic Petri dishes tightly binds CB-SCs without interfering with their immune modulating capability.

The chamber for co-culture of lymphocytes and CB-SCs includes nine discs of the material with adherent CB-SCs sandwiched between a top cover plate and a bottom collecting plate.[1]

Applications

A Phase I/II open-label trial of stem cell educator therapy was completed in February 2012 for possible use treating type 2 diabetes.[3]

A single treatment is reported to cause safe and lasting improvement in the patient's own control of blood sugar and hence the practical treatment of type 1 diabetes, by reducing autoimmune attack on the islets of Langerhans cells that produce insulin.[4]
