Egg cells are the largest single cells on the planet ... "After it's fertilized, the oocyte will become the future animal," says study co-author Sayantan Dutta, a researcher at Princeton and ...

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 ...

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 ...

Single sperm freezing: By freezing one sperm cell in an empty shell of an animal egg so it can be retrieved after thaw. This is done for TESA (see #27) when there are only a few detectable ...

The middle piece is packed with mitochondria to release energy needed to swim and fertilise the egg. The tail enables the sperm to swim. The nerve cell is extended, so that nerves can run to and ...

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...

Animal embryogenesis is the process by which the embryo develops from the fertilised egg cell. Important events that occur during embryogenesis are gastrulation, formation of the early nervous ...

Melina Schuh has been fascinated with ovarian germ cells, or oocytes, since she began her graduate ... but cautioned against designing medical therapies to delay ovarian aging or improve egg quality ...

Now MIT scientists have used light to control how a single cell jiggles and moves during its earliest stage of development. The team studied the motion of egg cells produced by starfish—an ...
