Maternal Storage in the Mammalian Oocyte

Part of the Current Topics in Pathology book series (CT PATHOLOGY, volume 62)


As early as 1896, Wilson stated that embryogenesis commences during oogenesis. Much evidence now exists suggesting that at least in invertebrates and lower vertebrates the information controlling early embryonic development is programmed during oogenesis (see reviews by Davidson, 1968; Davidson and Hough, 1972; Gross, 1972; Smith, 1972; Gross et al., 1973a).
