简介：
Overview
This protocol describes an imaging-enabled bioreactor for the selective removal of the endogenous epithelium from the rat trachea, facilitating the homogeneous distribution of exogenous cells on the lumen surface. The system allows for long-term in vitro culture and direct microscopic visualization of airway tissues during manipulation procedures.
