Abstract
Fifteen lymphoblast cell lines, including B[bone marrow-derived]-cell, T[thymus-derived]-cell, Null cell and myeloblast cells, were examined for the production of human neutrophil migration-inhibition activity. Only 1 T-lymphoblast cell line established from a patient with hairy cell leukemia produced a neutrophil migration-inhibition factor spontaneously and after stimulation with Con [concanavalin] A and PHA [phytohemagglutinin].
