Thyroid-Related Protein Expression in the Human Thymus

Figure 5

Expression of NIS protein in the Tg-positive thymus specimen. Sodium iodide symporter (NIS) is observed inside the vasculature stained with the CD31 antibody (a and b; arrows) and in thymocytes (b and d; arrowheads). Hassall’s corpuscles were stained with cytokeratin. But Hassall’s corpuscles were not observed in this thymus specimen. The low (a and c) and high (b and d) magnifications of the images are 100x and 400x, respectively. The scale bars represent 200 μm (a and c) and 50 μm (b and d).
