Cell-to-cell communication properties of Auerbach's plexus cell in culture.

Cultured Auerbach's plexus cells are coupled by low-resistance channels that permit the cell-to-cell passage of electrical current and fluorescein dye. The permeability of their intercellular junctions is blocked by the increased concentration of cytoplasmic Ca2+, thereby indicating that the cell-to-cell communication properties in cultured Auerbach's plexus cells are modulated by the cytoplasmic level of Ca2+.
