The carcinogenic process in the liver is a multistep process, characterised by an altered ratio between cell proliferation and cell death. In the last few years, we have undertaken studies aimed at determining the possible differences exhibited by two different types of cell proliferation, namely compensatory regeneration and direct hyperplasia at a molecular and cellular level. These two types of proliferative stimuli appear to play different roles in liver carcinogenesis. The scope of this article is to summarise the present knowledge about the differences in the expression of genes involved in the entry of liver cells into cell cycle, between liver regeneration following cell loss and/or cell death and direct hyperplasia induced by primary mitogens.

Abstract
The carcinogenic process in the liver is a multistep process, characterised by an altered ratio between cell proliferation and cell death. In the last few years, we have undertaken studies aimed at determining the possible differences exhibited by two different types of cell proliferation, namely compensatory regeneration and direct hyperplasia at a molecular and cellular level. These two types of proliferative stimuli appear to play different roles in liver carcinogenesis. The scope of this article is to summarise the present knowledge about the differences in the expression of genes involved in the entry of liver cells into cell cycle, between liver regeneration following cell loss and/or cell death and direct hyperplasia induced by primary mitogens.
