TLDR
Depending on the type of activating stimulus, oocytes exhibit the capacity for full activation at different ages, and the oocyte arrest in M III is similar to M II and can be released by subsequent activation.About:

Microtubule and chromatin behavior follow MAP kinase activity but not MPF activity during meiosis in mouse oocytes
TL;DR: The precise timing of MAP kinase activation versus MPF activation is studied during mouse oocyte maturation and, in parallel, morphological events such as changes in microtubule organization and chromatin condensation are studied.

Egg-to-embryo transition is driven by differential responses to Ca(2+) oscillation number.

TL;DR: There is strong evidence that a single Ca(2+) transient-driven signaling system can initiate and drive a cell into a new developmental pathway, as well as can account for the temporal sequence of cellular changes associated with early development.

Mos is required for MAP kinase activation and is involved in microtubule organization during meiotic maturation in the mouse.

TL;DR: Observations present the first evidence, in intact oocytes, of a role for the Mos/.../MAP kinase cascade in the control of microtubule and chromatin organization during meiosis.

Dynamics of the calcium signal that triggers mammalian egg activation.
Karl Swann,Jean-Pierre Ozil +1 more
TL;DR: This chapter focuses on the way that changes of intracellular Ca2+ are generated in mammalian eggs, and describes how theseCa2+ changes affect the subsequent development of the embryo.

16 - Sperm Competition in Mammals
TL;DR: In this paper, the authors focus on the fact that as compared to other mammals, including primates, humans are behaviorally, anatomically, and physiologically monandrous.

An Air-Drying Method for Chromosome Preparations from Mouse Eggs
TL;DR: The eggs, after being washed out from the genital tract, are put into hypotonic (1%) sodium citrate and left to stand at room temperature for 5–15 minutes and the duration of treatment is not very long.
Journal ArticleDOI
Development of blastomeres of mouse eggs isolated at the 4- and 8-cell stage.
TL;DR: Investigations by Seidel and Tarkowski have shown that although the majority of 1/2 blastomeres can regulate and develop into smaller but otherwise normal blastocysts, som e of them give rise to purely trophoblastic vesicles devoid of the inner cell mass.
Journal ArticleDOI
A free calcium wave traverses the activating egg of the medaka, Oryzias latipes.
TL;DR: It is concluded that the fertilization wave in the medaka egg is propagated by calcium-stimulated calcium release, primarily from some internal sources other than the large cortical vesicles.
Journal ArticleDOI
Calcium rises abruptly and briefly throughout the cell at the onset of anaphase
TL;DR: The close temporal association of the [Ca2+]i transient with the onset of anaphase suggests that calcium may have a signaling role in this event.
