Abstract

The myeloid panel of monoclonal antibodies (mAbs) submitted to the Third Swine CD Workshop were analysed for reactivity with bone marrow haematopoietic cells (BMHC). Using single and triple immunofluorescence labelling by flow cytometry (FCM), the mAbs were grouped according to their capacity to recognise myeloid cell populations and/or maturation stages. Group 1 consisted of mAbs labelling the majority of myeloid BMHC, including neutrophilic, eosinophilic and monocytic cells. The ligands for SWC3 and CD11b-like mAbs of group 1 showed a maturation-dependent intensity of expression. The other antibodies of group 1 reacted with BMHC to give a sharp, single peak. Group 2 mAbs reacted only with monocytic cells. The anti-human CD49e mAb Sam-1 was the only mAb detecting the majority of monocytic cells, but not other BMHC. The mAbs in group 3 recognised antigens expressed on granulocytes, but not monocytes. The previously identified SWC8 in this group proved to be useful in differentiating major population of BMHC when cells were double labelled with the pan-myeloid SWC3. Other mAbs within group 3, such as MIL4 and TMG6-5 (an anti-human CD11b), only recognised subsets of neutrophils and eosinophils. Group 4 mAbs reacted with the more mature subpopulations of neutrophils and monocytes. Some of these antibodies might prove useful for assessment of cell maturity, such as anti-CD14 and the anti-human CD50 mAb HP2/19.
