Analyses of AM morphology in healthy and diseased lungs by light microscopy. Cytospins from BAL samples from SPC-HA and SPC-HAxTCR-HA were stained with May-Grünwald and Giemsa reagent (Pappenheim method), and cell morphology was analyzed by light microscopy. Representative images of alveolar macrophages from n = 4 mice/group at ×63 magnification are depicted. Scale bar 10 µm. Black arrows indicate membrane protrusions
