Figure Lengend Snippet: Benchmarking co-culture model with in vivo P. aeruginosa transcriptomic datasets directly isolated from the airways of CF subjects. ( a ) Accuracy analysis using gene-wise mean and standard deviation values from in vivo samples in Lewin et al., 2023 as reference. Genes were considered accurate if their expression was within 2 standard deviations of the mean in the in vivo sample. ( b ) PCA plots showing sample distribution by condition (Magenta: co-culture; green: bacterial culture in isolates; purple: in vivo) or by study of origin (Orange: this study; purple: Cornforth et al., 2018 ; pink: Kordes et al., 2019 ; blue: Rossi et al., 2018 ). ( c ) Volcano plots displaying gene log 2 fold change and -log 10 adjusted p-value comparing transcriptomes of in vivo P. aeruginosa (left) or co-cultured PAO1 (right) to those of all pure bacterial culture samples.
