Although changes in membrane potential and intracellular Ca2+ (Cai ) during fertilization in starfish oocytes have been known for long time, little is known precisely about how and what kind of channels are involved during oocyte maturation and in fe

Animal spermatozoa navigate by sensing ambient chemicals to reach the site of fertilization. Generally, such chemicals derive from the female reproductive organs or cells. Exceptionally, squid spermatozoa mutually release and perceive carbon dioxide

Sperm-egg interaction depolarizes the egg membrane, allowing the sperm to enter; however, if the egg membrane is not allowed to depolarize from its resting potential (e.g. by voltage-clamp), the sperm will not enter. Previous studies demonstrated tha

Most animal cell types regulate their cell volume after an osmotic volume change. The regulatory volume increase (RVI) occurs through uptake of NaCl and osmotically obliged water after osmotic shrinkage. However, apoptotic cells undergo persistent ce

The present work aims to study the effects of estrogen or endocrine disrupters (EDs) on the dynamic changes in intracellular Ca(2+) concentration of mouse immature oocytes (IOs) loaded with Ca(2+)-sensitive dye Fura-2 using an image analyzer. The maj

An increase in intracellular Ca2+ concentration ([Ca2+]i) at a focal plane was recorded simultaneously with sperm-egg binding and membrane current upon insemination of sea urchin Hemicentrotus pulcherrimus eggs. No change in current and [Ca2+]i occur

The mechanism of the elevation of intracellular free Ca2+ ([Ca2+]i) induced by a single sperm in eggs of the sea urchin Lytechinus variegatus was investigated. Simultaneous measurements of [Ca2+]i, and of the activation current, were carried out on e

Behavioral traits of sperm are adapted to the reproductive strategy that each species employs. In polyandrous species, spermatozoa often form motile clusters, which might be advantageous for competing with sperm from other males. Despite this presume

Upon fertilization, the concentration of intracellular Ca2+ (Cai) in sea urchin eggs increased up to 3 microM when measured with fura-2, a fluorescent Ca indicator and the increase in Cai traversed from the sperm entry point as a wave over the entire
