Outline of Final Research Achievements |
We have previously reported that IL-2-stimulated CD56+ cells derived from the liver exert vigorous cytotoxicity against HCC. To differentiate NK cells, we incubated bone marrow-derived CD34+ hematopoietic progenitor cells in 5% serum-supplemented X-VIVO-15 medium containing SCF, Flt-3, IL-7, and IL-15. These NK cells expressed NKp46, a specific receptor of NK cells, and were phenotypically similar to resident NK cells, i.e. they expressed TRAIL, NKG2D, and CD226. The propagated NK cells produced IFN-γ. The propagated NK cells exhibited vigorous cytotoxicity against HCC cell lines by using 51Cr release assay. We have also developed a method to differentiate CD34+ hematopoietic progenitor cells from fibroblast-derived iPS cells. The use of NK cells for immunotherapy relies on the availability of large numbers of purified NK cells with optimal anti-HCC activities. This adaptive immunotherapy with these cells may be a promising modality to prevent the recurrence of HCC after hepatectomy.
