Abstract
The reaggregation of dissociated adult rat liver cells maintained in vitro for up to 96 h is described. Cultures were examined by dark-ground fluorescence and electron microscopy. Spaces resembling bile canaliculi were formed between reaggregated hepatocytes. Desmosomes and ‘tight’ junctions were formed between hepatocytes but ‘gap’ junctions were not detected. In older cultures structural damage was observed in many hepatocytes and some of them ingested cell debris by phagocytosis. Structures resembling bile ducts and sinusoids were also formed but complex association between all three types of cell aggregate was not observed.
