The effects of KLF4 on immunohistochemical staining of hepatic tissue from CCl4-induced, acutely injured livers. (a) Immunohistochemical staining of apelin, KLF4, and cyclinD1 protein in different groups of mice (magnification: ×400). The apelin, KLF4, and cyclinD1 indices were calculated as follows: positive cells/total intimal cells. (b–d) Quantified results are given as means ± S.E.M of four independent experiments. ∗P < 0.01 compared with GFP group. (n = 6 in each group).
