Immunoreactivity photomicrograph sections from the spleen, liver and kidney of broiler chickens naturally infected with myelocytomatosis; A Spleen showing staining of sub-capsular area that extending to the splenic trabeculae (arrow) and around lymphoid follicles (Scale bar: 100 µm), B Spleen showing staining of lymphoid follicle (Scale bar: 20 µm), C Spleen showing staining of connective tissue capsule (arrow) (Scale bar: 50 µm), and D Spleen showing staining of lymphoid tumor cells scattered within white pulp (Scale bar: 50 µm). E Liver showing staining of the hepatic parenchyma, especially around congested sinusoids (Scale bar: 50 µm), F Higher magnification of the previous photo showing antigen staining (arrow) (Scale bar: 20 µm), G Liver showing staining of the liver capsule and subcapsular area (Scale bar: 50 µm), H Liver showing staining around the central vein (Scale bar: 50 µm), I Kidney showing staining of the lining epithelium of renal tubules (arrow). (Scale bar: 50 µm), and J Kidney showing staining of inter-tubular area (Scale bar: 20 µm)
