CiMaas’ leading product to fight cancer is Natural Killer (NK) cells. These cells kill tumor cells directly as has been observed in pre-clinical studies, as well as in clinical studies (patients with myeloid leukemia). To obtain a large number of these NK cells to treat patients, so-called feeder cells are needed to stimulate the proliferation and activation of NK cells.
