This type of treatment is currently being done in China. Is this similar to what Researchers at Wake Forest University are doing with the cancer resistance mice?
Chinese centers now offering Lymphocyte/NK cell transfusion
In this method, compatible blood from the closest relatives (parents, siblings) are collected and the lymphocytes are isolated. The NK (Natural Killer) cells, which are the body’s main cancer-fighting cells, are isolated, and the NK-rich fraction is transfused into the patient. This can be repeated at intervals.
