"There were also models made which got the process down to three to six hours, in an outfield/outpatient type setting."

I think we should not confuse this technique for HIV/Lymphoma patients with the original technique. As I remember, the original process involved apheresis (which can now be done comparatively simply, in most locations) whereas the new technique involves a bone marrow transplant. In the original trial drugs where used to encourage stem cells to be produced in the marrow and taken up in the blood. Apheresis was then used to harvest these cells. In the current trial, as I understand it, bone marrow will be extracted, modified and transplanted back into the patient. This is quite different and more complicated.
