Histological evaluation of tissues from heme oxygenase-1 deficient (HO-1^−/−) mice. A: Hematoxylin-eosin staining of the spleen from the wild-type (HO-1^+/+, left panel) and HO-1^−/− (right panel) mice (age 8–12 weeks). Insets in both panels represent staining for HO-1 in the spleen using a polyclonal rabbit anti-rat HO-1 antibody (brown color). B: Iron staining with Prussian blue (arrows) of kidney (K) and liver (L) tissue from HO-1^−/− (left panel) and HO-1^+/+ (right panel) mice (age 24 weeks). Bar = 100 μm.
