Dye coupling in Purkinje cells of organotypic slice cultures.
Cerebellar slice cultures of newborn rats showed poorly developed dendritic arborization of Purkinje cells, whereas cultures of 10-day-old rats revealed prominent dendritic branching. Gap junctional intercellular communication between Purkinje cells, investigated as dye transfer of microinjected neurobiotin, occurred through dendro-dendritic contacts, with decreased dye spreading in old cell cultures. These results indicate a possible correlation of gap junctional intercellular communication and the development of Purkinje cells.
