Abstract

A monoclonal antibody (S17-12), previously described to recognize subsets of myelomonocytic cells, is demonstrated to bind CD9 antigen, a surface marker of B-cell precursors, platelets and several non-hematopoietic tissues. The proportion of S17-12, CD9-positive leukemic cells was determined in 102 patients with acute non-lymphocytic leukemia. It was found to be above 75% in 14/22 M3 cases (including 3/3 of microgranular variant) and only in 1/80 cases of different FAB subtype. Complete reactivity (>95%) of leukemic clonogenic cells with CD9 MoAB was restricted to 4/18 M3 cases. Therefore, a high proportion of CD9-positive cells seems to be peculiar to M3 cases. This may help in the diagnosis of cases that lack typical morphological features.
