Identification and Characterisation of tracheal cartilage derived stem cells for airway tissue engineering / Navid Moshkbouymatin

DOI (Published version): 10.23889/Suthesis.53568

Abstract

The trachea is a complex organ composed of multiple cell types and is just one integral part of the respiratory system and as a result of injury or insult there is an immediate need to engineer a neo-trachea as there currently no long-term treatments for tracheal defects. This thesis has for the fir...
