Figure Lengend Snippet: AAV6 shows high infection efficiency and specificity in lung epithelial cells (A) Schematic illustration of IT injection of AAV-GFPs followed by lung harvest at day14 for fluorescence-activated cell sorting (FACS) and immunofluorescence (IF) staining analysis. (B) The proportion of GFP + cells in live cells in AAV5-GFP-, AAV6-GFP-, and AAV9-GFP-infected lungs by flow cytometry analysis. n = 4 mice per group. (C) The mean GFP intensity in AAV5-GFP-, AAV6-GFP-, and AAV9-GFP-infected lungs by flow cytometry analysis, normalized by that in AAV9 group. n = 4 mice per group. (D) Representative images of GFP immunofluorescence in AAV5-GFP-, AAV6-GFP-, and AAV9-GFP-infected lung sections. Scale bar, 200 μm. (E) The proportion of GFP + cells in different cell types by flow cytometry analysis. n = 4 mice per group. (F and G) Representative images of IF staining of SPC (AT2 cells), RAGE (AT1 cells), CC10 (club cells), and acetylated-tubulin (ciliated cells) in AAV6-GFP infected lung sections. Scale bar, 40 μm. (B, C, and E) Mean ± SEM and p values were analyzed by one-way ANOVA. Data are representative of three independent experiments.
