Tissue engineering applies the principle of engineering and life sciences towards the development of biological substitute that restore, maintain or improve tissue or organ function. Scientists grow tissues or organs in vitro and implant them when the body is unable to prompt into healing itself. This presentation aims to highlight the potential clinical application of engineered tissues being researched on at the Tissue Engineering Centre, Universiti Kebangsaan Malaysia Medical Centre.
Normal tracheal mucociliary clearance is the key to maintaining the health and defense of respiratory airway. Therefore the present of cilia and mucous blanket are important for tracheal epithelium to function effectively. In the present study, we prepared a tissue engineered respiratory epithelium construct (TEREC) made of autologous respiratory epithelium cells, fibroblast and fibrin from sheep owns blood which replaced a created tracheal mucosal defect. Scanning electron microscopy (SEM) showed encouraging result where immature cilia were present on the surface of TEREC. This result indicates that engineered respiratory epithelium was able to function as normal tissue.
