Thyroid-Related Protein Expression in the Human Thymus

Figure 4

Expression of Tg protein in the Tg-positive thymus specimen. Thyroglobulin (Tg) was identified in the vasculature stained with the CD31 antibody (a and b). Tg was observed in thymocytes (c) and germinal center (d). The positive stained cells in the germinal center (arrows) are indicated. The low (a) and high (b) magnifications of the images are 100x and 400x, respectively, and (c) and (d) of the images are 400x. The scale bars represent 200 μm (a), 20 μm (b), and 50 μm (c and d).
