Cell-to-cell contacts in primary cultures of dissociated chicken embryonic brain.
The fine structure of intercellular contacts was studied in primary cultures prepared from chicken embryonic brain. Desmosomes were frequently seen between the glial cells. Synaptic contacts were observed among neuronal cell bodies and neural processes after 8 days in vitro. Gap junctions were revealed between glial elements suggesting a functional role in direct cell communication and providing a morphological basis for previous observations on potassium transport in cultures of dissociated brain cells.
