Mouse models of eosinophil-associated diseases have been used to study the mechanisms of disease pathogenesis. In this study, mouse-derived bone marrow cells were used in long-term (6 and 9 months) cell cultures of differentiated eosinophils and macrophages. IL-5 was used to differentiate the stem cells to eosinophils and GM-CSF was used to propagate macrophages from the bone marrow stem cells. The maximum time period for observing the eosinophil cultures was 252 days which is censurably longer than the 18 days culture period observed by others. The results were assessed by describing the microscopic cell morphology by Wright staining, modified Giemsa …
