In fact, egg cells have more mitochondria than any other ... Conversely, if mitochondrial function is compromised, the egg may suffer from insufficient energy production, increased oxidative ...

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it ...

If you're male, your body uses meiosis to create sperm cells; if you're female, it uses meiosis to create egg cells. Others cells in your body contain 46 chromosomes: 23 from your father and 23 ...

Scientists also know that the DNA that makes up genes is packed into structures called chromosomes, and that somatic cells contain twice as many chromosomes as gametes (i.e., sperm and egg cells).

"Abnormal sperm formation impairs their ability to fertilize egg cells," explains Yuki Kaneda ... shape and structure are key elements of sperm function, the findings from this study provide ...

Scientists used light to control how a starfish egg cell jiggles and moves during its earliest stage of development. Their optical system could guide the design of synthetic, light-activated cells for ...
