Prognostic role of the stromal cell derived factor-1 in patients with hepatitis B virus-related acute-on-chronic liver failure

Figure 3 Immunohistochemical staining for Ki67+ cells in livers. The distribution of Ki67 was predominantly in the portal areas, and minorly in the liver parenchyma. A: Strongly positive immunostaining in hepatitis B virus-related acute-on-chronic liver failure (ACLF) patients; B: Moderately positive immunostaining in chronic hepatitis B patients; C: Weakly positive immunostaining in healthy controls; D: Comparison of the amounts of Ki67+ cells between ACLF group and other groups. A-C: 200 ×. ACLF: Acute-on-chronic liver failure; CHB: Chronic hepatitis B.
