Auxin Regulation of Embryo Development
2014Important steps in plant development are made shortly after fertilization. In a brief succession of cell divisions, the zygote is transformed into an embryo, a multicellular structure carrying all fundamental tissue types and the meristems. Hence, embryogenesis offers excellent opportunities to dissect the molecular control and cellular mechanisms ...

Quality control of embryo development
Molecular Aspects of Medicine, 2013Although in recent years we have seen an undeniable improvement in the field of reproductive biology and medicine, the efficiency of in vitro fertilization (IVF) procedures remains relatively low, ranging from 4% to 40% depending on the patient's age. It is believed that this is in a large part caused by inaccurate assessment of embryo quality prior to

Mechanisms of plant embryo development
20001. Evolution in plants has favored both a simpler body plan with fewer cell types and the epigenetic flexibility to regenerate, via growth, dedifferentiation, and redifferentiation, to recover from environmental insults. It has become increasingly apparent that a plant cell uses external signals to differentiate and to maintain or to change the ...

Comparative kinetics of embryo development
Bulletin of Mathematical Biology, 1993A model of embryo energetics was fitted to data from the literature for species as different as snails and mammals. The model is based on assumptions about energy uptake, storage and utilization. It describes the animal by two state variables: volume and energy storage. Embryo weight is taken to be proportional to volume, yolk weight to energy storage,

Preimplantation Embryo Development
1993This volume contains the proceedings of the Serono Symposium on Preimplantation Embryo Development, held in Newton, Massachusetts in 1991. A recent resurgence of interest has occurred in this fundamental phase of embryogenesis and its relevance to basic research and applied fertility studies in both humans and animals.

The haemoglobins of developing duck embryos
Development, 1980ABSTRACT Three haemoglobins were isolated by ion-exchange chromatography from the haemolysates of embryonic duck erythrocytes up to 8 days of development. The component globins were characterized both by electrophoresis in dissociating conditions and by finger-printing analysis.

The ability to sustain mammalian gametes outside the body, to perform in vitro fertilization and embryo culture and subsequently to transfer the developing embryo back to the uterus with establishment of a viable pregnancy has been a reality for many decades.

Glycolipid patterns during xenopus embryo development
Cell Biology International, 1995ABSTRACTGlycolipid patterns have been studied during the first six days of Xenopus embryo development. Glycolipid contents showed a sharp increase more evident after the third day of development. Glucosylceramide and sulphatide are not only the most represented species, but also those which exhibit a statistically significant percentage change during ...

Gravity and Embryo Development
Current Obstetrics and Gynecology Reports, 2017Purpose of Review The precise impact that gravity, or the lack of gravity, plays in the key phases of mammalian reproduction remains a mystery. Humans and all other known living species have adapted to the effects of gravity on Earth. Only recently has the study of gravitational biology become truly possible.

Enabling Hamster Embryo Culture System: Development of Preimplantation Embryos
2019Development of preimplantation embryos, from fertilization to hatched-blastocyst stage, has been a challenging task, regardless of the mammalian species being studied. While the mouse model has been versatile for studying in vitro development of early embryos, other rodent species are important to gain insights into comparative early embryogenesis. The
