The changes in cellular proteins in regenerating rat liver after partial hepatectomy were examined by high-resolution two-dimensional electrophoresis. The cellular proteins in regenerating rat livers were separated into two fractions (soluble and insoluble protein fractions) and the proteins in each fraction were analysed by means of two-dimensional electrophoresis. A rapid increase in three proteins and a rapid decrease in two proteins were detected after partial hepatectomy. The changes in these proteins were in parallel with the regeneration rate of liver, suggesting a close relationship with the proliferation of liver after partial hepatectomy.
