these were : 1 ) cytotoxicity developed only from 'primed ' cell populations , 2 ) cytotoxicity developed within 24 hr after nago treatment , 3 ) dna synthesis was not required for the differentiation of cytotoxic cells during the first 24 hr of culture but both dna synthesis and cell proliferation were required for the cytotoxicity developing after 24 hr , and 4 ) all cytotoxicity induced by nago showed specificity for the priming alloantigen .
