Comparison between CNBio NHBE-NHLF and commercial SmallAir™-HF derived from healthy donors, regarding (A) IF staining (ZO-1: red, DAPI: blue); Scale bar: 50 µm, SEM images, and histological cross-sections (H&E staining) and IF staining displaying essential epithelial features, including acetylated α-tubulin (green) – marker for ciliated cells and MUC5B (red) – marker for goblet cells for the static culture and dynamic culture; Objective 40x, scale bar represents 50 µm. B The electrical resistance value at the end of the culture (Day 25). Error bars denote standard deviation, n = 6 for CNBio NHBE-NHLF and n = 2 for SmallAir™-HF derived from healthy donors
