The mechanisms that underlie early embryonic development in humans and cattle are very similar. Therefore, Ludwig-Maximilians-Universitaet (LMU) in Munich researchers argue that bovine embryos might ...

The first steps of human development—those that occur within the first few weeks of pregnancy—remain mysterious in many ways. Within a week of fertilization, human embryos form a blastocyst, which ...

The embryos of many species can stop developing when starved of nutrients, only to restart the process once these are restored – and scientists may have figured out how they do it. In the early stages ...

The embryo on the left is unedited, whereas the right has been edited to prevent it producing the OCT4 protein. The unedited embryo forms a stable structure called a 'blastocyst' but the edited embryo ...
