For open-looped treatment, the process is split between two days. On day one, the patient’s blood is drawn and about 250 milliliters of white blood cells are separated over the course of 4-5 hours (the red blood cells are immediately returned to the body). Overnight, the white blood cells are incubated in the Stem Cell Educator device for 17 hours. On day two, the patient returns to the facility and the treated white blood cells (GleukocellTM) are infused back into their body.
