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 ...

A snapshot from a simulation of how microtubules bend and direct material in a maturing egg cell into a twister-like flow. Egg cells are the largest single cells on the planet. Their size — often ...

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 ...

How do immature egg cells maintain genetic quality for decades before they mature? Scientists find unusual safeguards in this quiescent cell that may inform research into fertility. Out of all the ...

Human skin cells have been used to produce fertilizable eggs in a proof-of-concept study that heralds a potential new approach to infertility treatment. While much more research is needed to know how ...

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 ...

The research paves the way for people who currently rely on donor eggs and sperm to have their own genetic children ...

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 ...

New research shows it's possible to reprogram skin cells into eggs that can be fertilized in the lab, though it's just a proof of concept for now. Reading time 3 minutes A team of scientists has ...
