Morphologic analysis of bone marrow cells treated with the MoAb anti-FcγR, 2.4G2. BM (2 × 105 cells/mL) was cultured for 24 hours with rGM-CSF (10 U/mL), rIL-3 (10 U/mL), and rIL-5 (20 U/mL) with 2.4G2 (25 μg/mL), and the morphology of the cells was analyzed by transmission electron microscopy. (A) Representative example of cells cultured in the presence of 2.4G2. Arrows indicate cells with apoptotic features. (B) Higher magnification of 1 apoptotic cell where the characteristic eosinophilic granules are still intact (arrows).
