... of CARS frequencies for each spatial point ( Masia et al., 2013 , Di Napoli et al., 2014a ). In order to be compatible with living eggs and embryos, we acquired single xy images at 1 µs pixel dwell time (ten times less than for the single frequency images, but with equal power) across the CH-stretch...

... and other viscera. In the radially symmetric egg of Xenopus laevis , the earliest steps in DV axis determination are driven by microtubule-dependent localization of maternal components toward the prospective dorsal side. LR axis determination is linked in time to this DV-determining process...

...Rémi Dumollard; Petros Marangos; Greg Fitzharris; Karl Swann; Michael Duchen; John Carroll At fertilisation, repetitive increases in the intracellular Ca 2+ concentration, [Ca 2+ ] i , drive the completion of meiosis and initiate the development of the quiescent egg into an embryo. Although...

...Karolina Piotrowska; Magdalena Zernicka-Goetz The first cleavage of the fertilised mouse egg divides the zygote into two cells that have a tendency to follow distinguishable fates. One divides first and contributes its progeny predominantly to the embryonic part of the blastocyst, while the other...

...Xudong Shi; Simin Amindari; Kavitha Paruchuru; Dale Skalla; Heather Burkin; Barry D. Shur; David J. Miller ABSTRACT ZP3 is a protein in the mammalian egg coat (zona pellucida) that binds sperm and stimulates acrosomal exocytosis, enabling sperm to penetrate the zona pellucida. The nature of the ZP3...

... normal cleavage to the 8-cell stage. We discuss that although polarity of the postimplantation embryo can be traced back to the 8-cell stage and in turn to the organisation of the egg, it is not absolutely fixed by this time. * Corresponding author (e-mail: mzg@mole.bio.cam.ac.uk ) 06 06...

...Tie-Shan Tang; Jian-Bo Dong; Xiu-Ying Huang; Fang-Zhen Sun ABSTRACT At fertilization in mammals, the sperm activates the egg by inducing a series of oscillations in the intracellular free Ca 2+ concentration. There is evidence showing that this oscillatory event is triggered by a sperm-derived...

In ascidians, fertilization triggers spectacular reorganizations...

In sea urchin eggs, this first calcium signal...

...Keith T. Jones; Christian Soeller; Mark B. Cannell SUMMARY Mouse sperm-egg fusion was examined using two-photon and confocal microscopy. A delay of several minutes occurred between the first observable event of fusion (which was the diffusion of Ca 2+ -sensitive dyes from egg into sperm) and any...

An array of aligned microtubules that develops between the vegetal cortex and cytoplasm...

Injection of spermine into enucleated eggs showed that the ability to cleave was not restricted just to the period of normal cytokinesis (T = 1·0...

Early investigators were often guided by the localization of visible markers such as pigments or basophilic granules in animal eggs. Removal or local inactivation of cytoplasm containing such components...
