Abstract The dendritic processes and perinuclear cytoplasm of stellate-shaped perisinusoidal cells in frozen sections of rat liver were specifically labeled with antisera raised independently to glial fibrillary acidic protein (GFAP), the major component of intermediate filaments in astrocytes. A liver protein co-migrating with authentic GFAP and immunoreactive with GFAP antisera was demonstrated with immunoblots of brain and liver extracts enriched in intermediate filament proteins separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). This study presents yet another example of immunoreactivity to GFAP, or a highly similar protein localized outside the CNS, in cells of mesenchymal origin exhibiting some morphological features common to astroglia.
