From: Evaluation of an ex vivo fibrogenesis model using human lung slices prepared from small tissues
Fibrogenesis of the lung slices cultured for 7 days. Lung slices were treated with TGF-β1 (a, b) or CdCl2 plus TGF-β1 (c, d) as described in the previous section. They were harvested for histology process and the sections were stained with H/E (a, c) or Masson’s Trichrome stain (b, d). Arrows indicate the sphere-like pathogenic features and bars indicates 100 μm (a, c) and 50 μm (b, d)
