Lab grown models of embryos, made from clusters of stem cells, are getting increasingly complex. Ethicists, regulators and ...

Cell compaction is a crucial step in embryo development. Defective compaction prevents the formation of the structure that ensures an embryo can implant in the uterus. This stage is carefully ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment.

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment.

Human egg cells are still not well understood, because they are difficult to study. “ [They are] hard to work with, because the sample limitation is an issue,” says Böke.

The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...

There are transposable elements in the human genome that are active in the earliest stages of human embryo development, when there is significant molecular flexibility and plasticity. But the ...

U.S. scientists for the first time have used a cloning technique to get tailor-made embryonic stem cells to grow in unfertilized human egg cells, a landmark finding and a potential new flashpoint ...

This had previously been achieved with mouse egg cells, while human eggs had been successfully cultivated starting from a much later stage of development. "The latest study is the first time a ...

Researchers from Japan and France have successfully reconstituted the development of mouse egg cells, known as oocytes, from embryonic stem cells entirely in vitro, without the need for ovarian ...
