Bone marrow cytotoxic precursor T cells: alloantigen-induced cytotoxic T-cell responses by murine bone marrow cells in vitro
Journal Article
·
· Cell. Immunol.; (United States)
When bone marrow cells, obtained from C57BL/6 mice, were incubated in vitro with irradiated BALB/c spleen cells, cytotoxic activity against P815 tumor cells developed at 5 to 7 days of culture. This cytotoxic activity was T cell mediated and specific for the H-2 type of the allogeneic spleen cells used as stimulators. The generation of this cytotoxic T-cell activity was dependent on T cells present in the bone marrow since T-cell-depleted bone marrow cells failed to generate a cytotoxic response in vitro. Further, bone marrow cells incubated in culture medium not supplemented with 2-mercaptoethanol (2-ME) failed to generate alloantigen induced cytotoxic responses. Cytotoxic activity generated by bone marrow cells was always lower than the cytotoxic activity generated by alloantigen stimulated spleen cells. The possibility that differentiation of pre-T cells into cytotoxic effector T cells is taking place in this in vitro response is considered.
