Abstract
in vivo growth characteristics of myeloid leukaemia induced by whole-body irradiation of CBA/H male mice were examined in the strain of origin by procedures expected to enhance or depress immunological responses. Syngeneic growth in vivo (survival time and frequency of takes) was not modified by attempted active immunization with radiation-inactivated cells or by sublethal whole-body irradiation of recipients before inoculation of small numbers of clonogenic cells. Since the growth stimuli involved in in vivo repair of severely damaged normal haemopoietic tissue also did not modify the growth of the radiation-induced leukaemia cells in syngeneic passage, their growth in vivo in the irradiated primary hosts can be regarded as autonomous by the stage at which leukaemia was diagnosed. Challenge inocula in the "immunization" experiments were 1-9 clonogenic cells from 4 different passaged lines and in the whole-body radiation experiments, 1-10(3) clonogenic cells derived from 11 different primary hosts and 4 different passaged lines.
