Abstract:
:Flow cytometry represents an alternative method to agglutination assays for the accurate quantification of mixed field populations of erythrocytes observed after bone marrow transplantation. Murine monoclonal antibodies directed against the blood group ABH antigens were selected and processed in order to prepare ready-to-use fluorescent reagents. Anti-A (NaM87-1F6; IgG3), anti-B (NaM9-2E11; IgG3) and anti-H (NaM19-7E11; IgM) were purified, labelled with fluorescein isothiocyanate, and used in a direct flow cytometry assay. Anti-A1 (NaM1-1C9; IgG3) was no longer active after FITC-labelling and then was used in an indirect assay. The agglutination was prevented by formaldehyde pretreatment of erythrocytes. Using artificially-made double populations of erythrocytes, measured values with mixtures of 1-100% of cells were very closely related to expected values, showing both the sensitivity and the accuracy of the method. From careful investigation of a series of bone-marrow transplanted patients, we conclude that engraftments could be demonstrated earlier by flow cytometry than by agglutination, because minor populations (1-10%) of cells could be determined accurately only with labelled reagents. In addition, the disappearance of the donor cells on a long-term follow-up of patients enabled an earlier detection of graft failure in one case. The proposed method provides appreciable help to follow engraftment in patients and may have more general applications for the study of other haemopoietic chimaeras.
