Imaging of baboon airways by probe-based confocal laser endomicroscopy (pCLE). Ex vivo pCLE images of tracheal (A,B) and lung (C,D) explants. Prior to ex vivo imaging, tissues were non-specifically stained with acriflavine (green) and with either anti-human HLA-DR AF647 (A,C) or isotype control IgG2a AF647 antibodies (B,D) (red).
