The effect of solube antigens from polyoma tumor cells, liver antigens and PHA on lymph node cells from tumor bearers and on normal lymph node cells in CBA mice was studied. The stimulation index was calculated on the basis of incorporation of 14C-leucine in short-term cultures. The stimulation index was lower in lymphocytes derived from tumor bearers than those from normal donors. The blastoid responses to polyoma-associated antigens and PHA were similar, in contrast to liver-associated antigens. It was concluded that stimulation of liver antigens may be connected with different chemical structure, mainly of carbohydrate components.
