As shown in Figure 6, the density of Ki67-positive cells in the HCC tissue was much higher than that in the compared tissues such as peri-HCC tissues, liver biopsies collected from the animals in group A prior to HCC occurrence (pre-HCC), and the liver biopsies collected from the animals in group B long after HBV-inoculation. Here, MKI67 is linked to hepatocellular carcinoma.
