A type of epigenetic mark that ordinarily causes gene activation may instead facilitate gene silencing in oocytes, cells that must be kept in stasis throughout childhood if they are to have the ...

The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

Female mammals are born with all the egg cells they will ever have in their ovaries. Some of these cells therefore live for a long time – and must remain functional throughout this period. Experiments ...

An egg cell and a sperm need to hold together tightly in the Fallopian tube in order to fuse, resulting in the creation of a new organism. One key part of this process involves the proteins Juno, on ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Researchers have uncovered how egg cells prepare for the creation of life. Their work reveals the secrets of the Balbiani body (Bb), a remarkable structure that organizes essential molecules to guide ...

Scientists have made a landmark breakthrough that enables the creation of viable human egg cells from a skin cell, new research claims. The study, published in Nature Communications, detailed how US ...

According to a study published Tuesday in Nature Communications, researchers have successfully transplanted the nucleus from a skin cell to create new eggs that could allow patients to have ...

Human egg cells are often prone to chromosomal errors. As women age, the error rate increases sharply — and can contribute to infertility, pregnancy loss, and ...
