Figure 2: Morphology of polarized BMA cells. Stimulation of BMA cells for 24 h with IFNγ+LPS or IL-4 induced morphological changes that were visible under a light microscope at 20X and 40X magnification. M(IFNγ+LPS) macrophages exhibit an irregular phenotype represented by a rounded shape and abundance of vesicles. M(IL-4) macrophages are similar in appearance to untreated BMA cells [M(NT)]. The cells were examined via microscopy (Leica DM IRE2, bright field). One representative experiment is shown in this figure.
