Abstract
It has been reported earlier that when rat liver is dispersed to a single cell suspension, the parenchymal cells lose the ability to take up pyrimidine bases but acquire the ability to take up RNAase and macromolecular nucleic acids. It is now shown that these changes are largely reversed on intraperitoneal reaggregation of the parenchymal cells and that, in these respects, the aggregates behave more like the organized tissue than like the dispersed cells.
