Hepatocyte adaptations
WebThe general principle underlying oval cell activation is liver injury combined with an inability of hepatocytes to divide in response to the damage. For example if a DNA-damaging agent is administered followed by partial hepatectomy, hepatocyte mitosis is blocked, and oval cells emerge from the portal zone. Web6 aug. 2024 · If hepatocyte or cholangiocyte proliferation is seriously impaired, then each of the two cell types can transdifferentiate into the other and function as a facultative stem cell.
