(B) Section in the lung of a rat in IVI stem cell therapy group showing a bronchiole (b), a vessel with partially thickened wall (v), congested vessels (c) and extravasated RBCs (^*) (H&E, ×100). (C) Section in the lung of a rat in IVI stem cell therapy group showing normal alveoli (a) and alveolar sacs (S) lined by multiple cells exhibiting flat nuclei (arrows).
