Oro-pharyngeal administration of bleomycin induces severe lung fibrosis in transgenic mice. Representative low (× 5) and high (× 20) power images of normal mouse lung (A Ashcroft score 0) and total fibrous obliteration of the lung following bleomycin administration in TG mice (B Ashcroft score 8). C Distribution of Ashcroft scores across all treatment groups for bleomycin experiments (n = 815 sections)
