the findings of the present investigation suggest that expression of cytotoxicity induced in mlc is not necessarily restricted to the target cells syngeneic to the stimulator cells , but can be extended to any allogeneic target cells by the indirect effect of soluble factor secreted from stimulated cells that causes a polyclonal activation of cytotoxic precursors in the responding cell populations .
