Document: Infections by respiratory viruses are currently studied using cultured established cell lines, primary tissue-derived human cells, human organoids, ex vivo human lung tissue cultures, and animal models; however, all of these preclinical models have significant limitations (Supplementary Table 1 ) 9-11 . For example, cultured cell lines often need to be supplemented with exogenous proteases to enable viral propagation, whereas endogenous proteases that are naturally expressed by the airway epithelium exert this crucial action in humans 10 . Cell lines and even human cells grown in conventional cultures do not exhibit the highly differentiated tissue structures and functions seen in living human organs. Explant cultures of human respiratory tract tissue circumvent this limitation, but their availability is limited and their viability can only be maintained for short time (4-10 days) 11 .
