Figure 1326

Electron micrograph of a thymic (Hassall's) corpuscle. This relatively low magnification electron micrograph shows some of the nuclei (N) and cytoplasm of the concentrically arranged epithelioreticular cells of a thymic (Hassall's) corpuscle. Bundles of intermediate filaments, keratohyalin granules, and lipid droplets are also evident within the cytoplasm of the epithelioreticular cells. Fully keratinized cells (black layer) are present in the center of the thymic corpuscle, x 5,000. (Courtesy of Dr. Johannes A. C. Rhodin.)
