Maturity of associating liver partition and portal vein ligation for staged hepatectomy-derived liver regeneration in a rat model

Figure 1 Establishment of ALPPS model. A: Pictures of ALPPS, PHx, and sham models; B: Proliferation of ALPPS, PHx, and sham models. The X axis represented the day after operation while the Y axis represents the RML/WB (%); C: Representative image (100 ×) of Ki-67 stain by immunohistochemistry of each group at day 2 and 5, respectively; D: Proliferative index of different models, which was calculated by the mean of percentage of Ki-67 positive particle in four random visual fields (200×) of IHC stain. ^aP < 0.05, ^bP < 0.01, ^cP < 0.001; E: Protein level of represent expression of PCNA of each group. A: ALPPS; P/PHx: Partial hepatectomy; S: Sham; PCNA: Proliferating cell nuclear antigen; IHC: Immunohistochemistry; RML: Right middle lobe; WB: Body weight.
