DDAC induces inflammation and fibroproliferation in the lungs. Mice were intratracheally instilled with 0.01% of DDAC or the vehicle control and were sacrificed on day 7, 13, or 20 after the treatment⁶⁹. Lung tissue samples were subjected to histopathological examination. Representative images of the lung tissues stained with hematoxylin and eosin (A–D) and Masson trichrome (E–H) from the vehicle control (A, E) and DDAC-treated mice on day 7 (B,F), 13 (C,G) or 20 (D,H).
