Subcellular Localization of Tspo mRNA in healthy and diseased stomach tissue: In normal epiploon tissue (A,B) Tspo mRNA is found in adipose cells (AD) as well as in fibroblasts (F). In healthy stomach Tissue (C,D) Tspo mRNA is localized in the cytoplasm of parietal cells (P), chief cells (Z), surface mucous cells (M) of the gastric glands and in the cytoplasm of plasma cells (P) and macrophages (W) and nuclei and cytoplasm of lymphocytes (L) located in the lamina propria. In stomach squamous cell. carcinoma (E,F) Tspo mRNA is localized in the cytoplasm of tumour cells and collagen fibres in the surrounding stroma. (G,H) Negative control for the subcellular localization of Tspo mRNA. Sense probes were used to probe tissue preparations and this was analysed colorimetrically and fluorescently. Tissues are magnified at 1000×.
