Reproductive biologists have identified the mechanism that triggers sperm's race to the egg, reports a study in Cell today. Stained sperm cells (Blue, nucleus; red, mitochondria; green, Hv1 protein ...

"Abnormal sperm formation impairs their ability to fertilize egg cells," explains Yuki Kaneda ... TEX38 localizes ZDHHC19 to the plasma membrane and regulates sperm head morphogenesis in mice ...

Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...

Cell membrane proteins hide secret gateways that can be used to modify cell behavior. This has been demonstrated in a study ...

The cell wall surrounds the plasma membrane and provides the cell tensile strength and protection. Plant cells have some specialized properties that make them distinct from animal cells.

A Yale-led research team has uncovered how a naturally occurring biological mechanism found in mammals is able to prevent sperm cells from interacting with an egg, preventing fertilization.
