Preclinical drug trials frequently require the evaluation of animal bone marrow, a time-consuming process requiring the skills of a highly trained hematologist. In the present study, a flow cytometric technique was developed that could effectively replace the need for manual bone marrow differentials in rats. Peroxidase activity, measured indirectly with 2'7'-dichlorofluorescein, was coupled with the use of species-specific T- and B-lymphocyte antibodies and cell size to produce a flow cytometric analysis of rat bone marrow. Accurate identification of lymphocyte, proliferating and maturing erythroid and myeloid, and megakaryocyte populations was confirmed by cell sorting. Flow cytometry yielded differentials that were indistinguishable from manual differentials and published reference ranges. Enumeration of lymphocyte numbers with monoclonal markers is a key advantage of flow cytometric differentials because misidentification of lymphocytes in poorly prepared or stained bone marrow smears is a common problem. The most apparent advantage is increased throughput and reproducibility. Operator training for analysis using flow cytometry can be readily accomplished within a few days as opposed to the extensive training required for individuals performing manual bone marrow differentials. This methodology provides a high-volume, rapid, and relatively low-cost tool for the reliable evaluation of rat bone marrow differentials that has been heretofore unavailable.
