the cellular basis of the cytolytic cross-reactivity observed in primary allogeneic ( c56bl/6 anti-dba/2 and c57bl/6 anti-c3h/he ) mixed-leukocyte cultures ( mlc ) was investigated by analysis of the specificity of clonal progeny derived from individual cytolytic t lymphocyte ( ctl ) precursor cells ( ctl-p ) contained within these populations .
