| Outline of Final Research Achievements |
Human amnion-derived cells(HAMD) are considered to be a promising alternative cell source for clinical use because of their proliferation and differentiation ability. The cells can easily be obtained from human amnion without medical intervention. HAMD express immunosuppressive factors CD59 and HLA-G, implying that they may have an immunosuppressive function. We investigated the effect of HAMD on NK cell and monocyte function. HAMD inhibited the cytotoxicity of NK cells to K562 cells, depended on the NK/ HAMD ratio. The inhibition of NK cytotoxicity was recovered by continuous culturing without HAMD. This inhibition was related to the decreasing of the activated NK receptors and the production of IFN-γ in NK cells, to the increasing of the expression of IL-10 and PGE2 in HAMD. Antibody to IL-10 or PGE2 inhibitor recovered the NK cytotoxicity. HAMD also suppressed the activity of TNF-α and IL-6 in monocytes. These data suggested that amniotic cells have immunosuppressive activity.
