Figure-2.

(a) Positive in situ hybridization (ISH) results from lung tissues. Multifocal ISH positive signals were observed as brown grains of chromogenic staining within cytoplasm of pneumocytes. 200× magnification with a scale bar equivalent to 100 µm. (b) Positive ISH results from lung tissues. Multifocal ISH positive signals were observed as brown grains of chromogenic staining within cytoplasm of pneumocytes. 400× magnification with scale bar equivalent to 50 µm. (c) Positive ISH results from inguinal lymph node tissue. Multifocal ISH positive signals were observed as brown grains of chromogenic staining within cytoplasm of lymphocytes. 200× magnification with scale bar equivalent to 100 µm. (d) Positive ISH results from mesenteric lymph node tissues. Multifocal ISH positive signals were observed as brown grains of chromogenic staining within cytoplasm of lymphocytes. 400× magnification with scale bar equivalent to 50 µm.
