WebThymus: medulla. Though primarily composed of epithelial reticular cells, other cells types are present in the medulla. One population of epithelial reticular cells forms Hassall’s corpuscles, also called thymic corpuscles. Hassall’s corpuscles occur only in the medulla.

WebJun 25, 2016 · (A) This equivocal Hassall’s corpuscle (arrow) from a B6C3F1 mouse has granular cytoplasm and contains necrotic debris. It is shown to demonstrate the difficulty in clearly recognizing Hassall’s corpuscles in the rodent. Without a special stain, such as a keratin stain, one cannot identify rodent Hassall’s corpuscles with certainty.

Thymus: Histology, features, cell types and anatomy

WebHassall’s corpuscles (HCs) are composed of cornifying, terminally differentiated medullary thymic epithelial cells (mTECs) that are developed under the control of Aire. Here, we demonstrated that HC-mTECs show features of cellular senescence and produce inflammatory cytokines and chemokines including CXCL5, thereby recruiting and … WebThis is important to keep in mind because the structural cells of all other lymphatic organs are mesodermal. Parencyhmal cells can most easily be recognized in the medulla as large, stellate, pale staining cells. In the thymic medulla, one can find characteristic Hassall's corpuscles, which are composed of keratinized epithelial cells. WebHassall: ( has'ăl ), Arthur, British physician, 1817-1894.
