Survivin and Ki-67 staining in the ascending colon. (A/B) Survivin staining of the ascending colon in the normoxia (a) and the ischemia (b) group (representative figures). Survivin positive cells were immunohistochemically labeled in brown. (I): single crypt; (II): ascending colon. Nuclei were counterstaining with hematoxylin (blue). Magnification: 400×. Scale bar: 10 μm. (C/D) Ki-67 staining of the ascending colon in the normoxia (c) and the ischemia (d) group (representative figures). Ki-67 positive cells were immunohistochemically labeled in brown. Nuclei were counterstaining with hematoxylin (blue). Magnification: 400×. Scale bar: 10 μm
