title: [Tissue-specific antigen of chick adenohypophysis appearing at early stages of histotypic differentiation].
abstract: The tissue-specific water-soluble antigen characterized by alpha1-globulin electrophoretic mobility was revealed in chick adenohypophysis. The antigen was shown to appear in embryogenesis at early stages of histotypical differentiation of the adenohypophysis by indirect immunofluorescence. The first cells with specific fluorescence were found simultaneously in the cephalic and caudal lobes of 6-day embryo adenohypophysis. The bright patterned fluorescence was observed in all cellular cords of the adenohypophysis by the 8--10th day of the development. This antigen may be used as a common marker for pituitary cell differentiation.
