Sorted by: Date Added To NTRS in Descending order Fertilization: motility, the cytoskeleton and the nuclear architecture Author(s): Schatten, G.; Schatten, H. Abstract: No abstract available NASA Center: NASA (non Center Specific) Publication Year: 1987 Added to NTRS: 2006-08-02 Document ID: 20050000936 Meiosis, egg activation, and nuclear envelope breakdown are differentially reliant on Ca2, whereas germinal vesicle breakdown is Ca2 independent in the mouse oocyte Author(s): Tombes, R. M.; Simerly, C.; Borisy, G. G.; Schatten, G. Abstract: During early development, intracellular Ca2 mobilization is not only essential for fertilization, but has also been implicated during other meiotic and mitotic events, such as germinal vesicle breakdown (GVBD) and nuclear ... NASA Center: NASA (non Center Specific) Publication Year: 1992 Added to NTRS: 2006-08-02 Document ID: 20050000716 Activation of maternal centrosomes in unfertilized sea urchin eggs Author(s): Schatten, H.; Walter, M.; Biessmann, H.; Schatten, G. Abstract: Centrosomes are undetectable in unfertilized sea urchin eggs, and normally the sperm introduces the cell's microtubule-organizing center (MTOC) at fertilization. However, artificial activation or parthenogenesis triggers ...

G.; Schatten, G. Abstract: The distribution of lamins (described by Gerace, 1978, as major proteins of nuclear envelope) during gametogenesis, fertilization, and early development was investigated in germ cells of a mouse (Mus musculus), an echinoderm ... NASA Center: NASA (non Center Specific) Publication Year: 1986 Added to NTRS: 2004-11-03 Accession Number: 91A19817; Document ID: 19910035194 Nuclear lamins and peripheral nuclear antigens during fertilization and embryogenesis in mice and sea urchins Author(s): Schatten, G.; Schatten, H.; Simerly, C.; Maul, G. G.; Chaly, N., et al. Abstract: Nuclear structural changes during fertilization and embryogenesis in mice and sea urchins are traced using four antibodies. The oocytes from virgin female mice, morulae and blastocytes from mated females, and gametes from ...

Abstract: Gravity has been a pervasive influence on all living systems and there is convincing evidence to suggest that it alters fertilization and embryogenesis in several developmental systems. Notwithstanding the global importance ...
