  • Title: [Induction of alpha- and beta-crystallin synthesis in organ cultures of the adenohypophyseal anlage of chickens as affected by 5-iododeoxyuridine and 5-bromodeoxyuridine].

    Journal: Ontogenez; 1986; 17(4):396-401. PubMed ID: 3748533.
    Abstract:
    The effects of 5-iododeoxyuridine and 5-bromodeoxyuridine on differentiation of the cells of adenohypophysis rudiment from 3, 4, and 5 day old chick embryos were studied in the in vitro organ culture. On the 7th day of cultivation most explants from 3 and 4 day old embryos formed lentoids and individual cells with the lens phenotype among the adenohypophysis tissue. Alpha-, beta- and delta-crystalline were immunochemically detected in them. When cultivating explants from 5 day old embryos, no lentoids formed. But the immunochemical study of serial sections made it possible to detect in individual explants single alpha-crystalline-containing cells. There is a period in the development of chick adenohypophysis, which lasts five days of incubation and during which the adenohypophysis rudiment retained its capacity for lens differentiation despite the fact that it is already determined in the adenohypophysis direction.
