Engineering rotating apical-out airway organoid for assessing respiratory cilia motility.

Motile cilia project from the airway apical surface and directly interface with inhaled external environment. Owing to cilia's nanoscale dimension and high beating frequency, quantitative assessment of their motility remains a sophisticated task. Here we described a robust approach for reproducible engineering of apical-out airway organoid (AOAO) from a defined number of cells.

Bioorthogonal Labeling and Chemoselective Functionalization of Lung Extracellular Matrix.

Decellularized extracellular matrix (ECM) biomaterials derived from native tissues and organs are widely used for tissue engineering and wound repair. To boost their regenerative potential, ECM biomaterials can be functionalized via the immobilization of bioactive molecules. To enable ECM functionalization in a chemoselective manner, we have recently reported an effective approach for labeling native organ ECM with the click chemistry-reactive azide ligand via physiologic post-translational glycosylation.
