Changes in a range of plasma membrane enzyme activities during the early period of liver regeneration are thought to be related to the initiation of DNA synthesis and the triggering of cellular activation. The sinusoidal plasma membrane was isolated from control and partially hepatectomized animals at various intervals during the pre-replicative phase. The specific activities of 5'-nucleotidase, (Na+ + K+)-ATPase, Ca2+-ATPase, Mg2+-ATPase showed that after partial hepatectomy changes in the enzyme activities at the sinusoidal plasma membrane region occur. These changes are probably related to the remodeling of the cell-surface that occurs before the division of hepatocytes.
