Smooth muscle cell accumulation in the lung parenchyma (horse #16-rom). A. Smooth muscle cells accumulate into the lung parenchyma (
) and disrupt the bronchiolar structure. Hematoxylin-eosin staining on paraffin-embedded sections. B. Immunostaining of smooth muscle cells using an anti-αSMA antibody shows the accumulation of fusiform cells (in green) within the lung parenchyma. C. Higher magnification shows organized actin filaments within the infiltrating cells. Nucleus are stained in blue with DAPI.
