Morphology and immunocytochemistry of the turtle pituitary gland with special reference to the pars tuberalis.

abstract：:Low-temperature-embedded tissue of the subcommissural organ (SCO) of the rabbit was analyzed for the basal route of secretory product by means of indirect immuno-metal cytochemistry (protein A-gold technique) at the electron-microscopic level. By use of (1) an antiserum against bovine Reissner's fibre (see Sterba et a...
