Injection of ICSBP modified cells (Ba-P210–ICSBP) generates immunologic memory for parental leukemia cells (Ba-P210).
(A) Survival of naive Balb/c mice (⋄) or Balb/c mice preimmunized with 106 Ba-P210–ICSBP cells (■) following intravenous injection with 106 Ba-P210 cells. Ten mice were used in each arm. (B) Balb/c mice received an intravenous injection of 7 × 106 spleen cells from naive (⋄) or Ba-P210–ICSBP immunized mice (■), along with 106 Ba-P210 cells on the following day. Five mice were used in each arm.
