Identification of Tracheal Cartilage Canals in Camel
Cartilage canals are vascular canals that commonly described in bone during embryonic development. They serve an important function in the ossification of the cartilage templates. Cartilage canals in permanent cartilage were uncommon. The current study identified the cartilage canal in the camel trachea. Tracheal samples were collected and processed for light microscopic examination. Cartilage canals were recognized in the camel trachea. Tracheal cartilage canals were confined to the peripheral region of the tracheal cartilage. Cartilage canals consisted of blood vessels and perivascular cells, some of which secrete cartilage matrix and transformed into chondrocytes. Thus, cartilage canals aim to provide the cartilage with chondrogenic potential cells to participate in the interstitial growth of the tracheal cartilage of camel. In conclusion, tracheal cartilage canals contain mesenchymal cells that participate in the interstitial growth of the tracheal cartilage. Future studies should investigate the role of the cartilage canals growth of the cartilage.
