Annulate Lamellae (Porous Cytomembranes): With Particular Emphasis on Their Possible Role in Differentiation of the Female Gamete

Cytoplasmic annulate lamellae in cultured cells: composition, distribution, and mitotic behavior

“…So far, the underlying mechanisms for this subcellular localization are unknown. No spatial association has been observed between AL and the Golgi apparatus; this argues against the "intimate relationship" between these two structures as suggested by some authors (for a review, see Kessel 1985). A systematic relationship of AL to lysosomes and peroxisomes can also be excluded.…”

“…In other investigations by electron microscopy, AL cisternae have been described to vesiculate shortly before the vesiculation of the nuclear envelope during egg maturation in amphibians (e.g., Kessel and Subtelny 1981; for a review, see Kessel 1985), and Longo has noticed as early as 1972 a linkage between the disappearance and subsequent reappearance of the nuclear envelope and a few AL during the first cleavage division of the sea urchin embryo (Longo 1972).…”

“…In some cells, AL consist of numerous stacked cisternae, whereas single cisternae are observed in other cells. AL have been found by electron microscopy in diverse plant and animal cells, especially in tumor and germ cells (for reviews, see Kessel 1983Kessel , 1985Ghadially 1988), and their formation can be induced or increased by viral infections or chemical treatments (for reviews, see Kessel 1989Kessel , 1992.…”

Electron microscopic study on oocytes, nurse cells and yolk formation inLeptestheria dahalacensis(Crustacea, Conchostraca)

“…The passage of nucleolar matter from the nucleus to the cytoplasm in the young oocytes of Leprestheria does not take place, as it does in several malacostracans (Kessel, 1968;Kessel and Beams, 1968;Dhainaut and De Leersnyder, 1976;Zerbib, 1980;Beams and Kessel, 1980) and in the cladoceran Daphnia (Zaffagnini, 1987), through extrusions of dense material, but rather through minute granules which unite in masses in the perinuclear cytoplasm. Moreover, in the previtellogenic oocytes of L. dahalacensis annulatae lamellae have not been observed, such as seen in oocytes of Triops (Sabelli Scanabissi and Trentini, 1979) and Daphnia (Zaffagnini, 1987).…”

“…In crustaceans there is a great deal of evidence of the extraoocytic origin of yolk precursors, as well as active yolk formation by organelles within the oocyte itself. In fact, ultrastructural researches have demonstrated that in most crustaceans protein yolk globules are of mixed origin (Hinsch and Cone, 1969;Wolin et al, 1973;Dhainaut and De Leersnyder, 1976; Beams and Kessel, 1980;Schade and Shivers, 1980;Zerbib, 1980;Souty, 1980Souty, , 1983; only in a few species has there been found an exclusively endogenous synthesis of yolk by the rough endoplasmic reticulum (alone or in association with the Golgi apparatus) (Beams and Kessel, 1963;Kessel, 1968; Ganion and Kessel, 1972), or by the smooth endoplasmic reticulum (Sabelli Scanabissi and Trentini, 1979). At the present time, the only case of exclusively exogenous origin of the protein yolk described occurs in the subitaneous eggs of Daphnia (Lucchi and Zaffagnini,1%9).…”
