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.

Mechanisms Regulating Pattern Formation in the Amphibian Egg and Early Embryo
TL;DR: The frog egg appeared to meet the definition of a mosaic egg, that is, one showing no pattern regulation, under experimental conditions, and the active cell failed to adjust its development to compensate for its defective neighbor.

Isolation, physicochemical properties, and macromolecular composition of zona pellucida from porcine oocytes.
TL;DR: The zonae were completely solubilized by a variety of conditions that do not break covalent bonds, and it is concluded that the zona pellucida is composed of several glycoprotein macromolecules to form supramolecular complexes and the integral zzonae is dependent on noncovalent forces.

Cortical granule distribution and cell surface characteristics in mouse eggs
TL;DR: A cytological analysis of serially sectioned unpenetrated and penetrated mouse eggs revealed the existence of a marked polarity in the distribution of cortical granules and of microvilli in the egg cortex.

THE USE OF LEAD CITRATE AT HIGH pH AS AN ELECTRON-OPAQUE STAIN IN ELECTRON MICROSCOPY
TL;DR: The stain reported here differs from previous alkaline lead stains in that the chelating agent, citrate, is in sufficient excess to sequester all lead present, and is less likely to contaminate sections.

A low-viscosity epoxy resin embedding medium for electron microscopy.
TL;DR: A low-viscosity embedding medium based on ERL-4206 is recommended for use in electron microscopy and has a long pot life of several days and infiltrates readily because of its low viscosity.

Oogenesis in Xenopus laevis (Daudin). I. Stages of oocyte development in laboratory maintained animals.
TL;DR: Six stages of oocyte development in the anuran Xenopus laevis can be divided into six stages based on the anatomy of the developing oocyte, and these stages have been correlated with physiological and biochemical data related to oogenesis.
