Figure Lengend Snippet: Growth in HTBE cells revealed attenuation of certain reassortant genotypes. Triplicate wells of fully differentiated HTBE cells were inoculated with the indicated viruses at an MOI of 0.001 PFU/cell and incubated at 33°C. Viral titers present in apical samples collected at the indicated time points were determined by a plaque assay on MDCK cells. The mean result of three replicates is plotted, with the standard deviation indicated by an error bar. (A) Growth of viruses with H3N2-derived PB2 in HTBE cells; (B) growth of viruses with pH1N1-derived PB2 in HTBE cells.
Article Snippet: Human tracheobronchial epithelial (HTBE) cells from a single donor were acquired from Lonza and were amplified and differentiated into air-liquid interface cultures as recommended by Lonza and described by Danzy et al. ( 79 ).
