Block2/Fig.12a Photomicrograph of thymus medulla.

block3_24.jpg - Fig.12a Photomicrograph of thymus medulla. This highmagnification photomicrograph shows the medulla withvarying numbers of circular bodies called Hassall's corpuscles(HC). The corpuscles are isolated masses of closely packed,concentrically arranged epithelioreticular cells; these cellsexhibit flattened nuclei. In addition to numerous thymocytes(T), the micrograph also shows epithelioreticular cells (arrows),with their large, pale-staining nuclei.Fig.12b A higher magnification photomicrograph shows thebasophilic thymocytes and the large, pale-stainingepithelioreticular cells.
