Propagation of HRV-C15 in different forms of human sinus epithelium. A). Pieces of human sinus mucosal tissue were either infected with HRV-C15 (2.8 × 108 RNA copies) (n=5) or B) dissociated into single cell suspension, passaged, and grown as a monolayer (n=3) or C) differentiated at ALI (n=3) and then infected with the same dose of HRV-C15. Samples were incubated at 34°C and tested immediately post-infection (PI) and again 48-72 hrs later for HRV RNA. *P<0.05.
