Fertilization causes mature oocytes or eggs to increase their concentrations of intracellular
calcium ions (Ca2+) in all animals that have been examined, and such Ca2+ elevations, in …

In marine invertebrates, as in most other organisms, normal development requires that only
one sperm nucleus joins with the egg nucleus at fertilization. The principal mechanisms …

The relationship between egg polarity and the adult body plan is well understood in many
bilaterians. However, the evolutionary origins of embryonic polarity are not known. Insight …

This purpose of this review is to look at the experimental evidence, both kinetic and
electrophysiological, that led to the hypothesis of a fast electrical block to polyspermy in sea …

We have clarified, for the first time, the spatiotemporal patterns of intracellular Ca2+
increases at fertilization and the Ca2+-mobilizing mechanisms in eggs of hydrozoan …

During maturation, oocytes must undergo a process of nuclear disassembly, or “germinal
vesicle breakdown”(GVBD), that is regulated by signaling pathways involving cyclic AMP …

Progress of Evo‐Devo requires broad phylogenetic sampling providing the data for
comparative analysis as well as new objects suitable for experimental investigation …

After purifying plasma membranes from isolated maize sperm cells by aqueous polymer two-
phase partition, peripheral and integral proteins were solubilized from the plasma …

Reproduction is the origination of new organisms from pre-existing ones. Among more than
35 separated forms of reproduction including several types of gamogony, parthenogenesis …

This review aims to summarize the information provided in this book and give an integrated
view of the process of fertilization in two different and separate groups of eukaryotic …
