Morphologic changes of immature and mature BMDCs. (A, B) The morphology of the BMDCs treated with GM-CSF plus IL-4 was observed under a light microscope (magnification: ×100 (A) and ×400 (B)). (C, D) The morphology of the BMDCs stimulated with LPS was also done under a light microscope (magnification: × 100 (C) and × 400 (D)). (E, F) The images of the BMDCs treated with GM-CSF plus IL-4 were scanned by a scanning electron microscope (SEM) with different magnifications, including around ×1,200 (E) and ×5,000 (F); (G, H) SEM images of the BMDCs stimulated with LPS were recorded with different magnifications, i.e., around ×1,200 (G) and ×5,000 (H).
