Transmission electron micrograph (TEM) of freeze-fracture preparation of infant ferret tracheal epithelium. This profile shows different aspects of gap junctions considered to be sites of intercellular communication. The particles represent channels visible on the cytoplasmic aspect (PF-face) of the epithelial cell membrane and the flattened area above the larger particle aggregate represents the extracellular aspect (EF-face).Magnification 50, 000x. | |
