Abstract

Estrogenic hormones induce morphologic and biochemical differentiation in the oviduct of the immature chick. Concomitant with the hormone-stimulated tissue growth, there was an increase in 4S RNA, as judged by polyacrylamide-gel electrophoresis, and a corresponding increase in cellular transfer RNA activity, as measured by the amino acid acceptor capacity. This system may be suitable for studying the relation of hormones to transfer RNA in a differentiating tissue.
