Thymus
The dark-staining cortex contains densely packed T-lymphocytes and is easily differentiated from the paler-staining medulla, where the lymphocytes are slightly more dispersed. The thymic stroma consists of a meshwork of epithelial reticular cells rather than a connective tissue, and hence, no fibers are present. One diagnostic feature of the thymus, Hassall’s corpuscles, are formed from epithelial reticular cells. 200x
