Notes:
Summary Tight junctions were found in the apical junctional complex of the adult rabbit subcommissural organ (SCO) in addition to zonulae adhaerentes and gap junctions of typical ependymal cells. Ventricular perfusion of ruthenium red before fixation was found to give excellent results for distinguishing between gap and tight junctions at the ependymal surface. The implication of tight junctions as a mechanical means of sealing off the SCO area from the cerebrospinal fluid and the use of ruthenium red as a tracer substance are discussed.
