A faithful model of the human blastocyst has been developed which replicates key phases of very early development from 4 to 13 days post fertilization, including attaching to layers of ...

Innovative research, presented today at the ESHRE 40 th Annual Meeting in Amsterdam, has introduced a novel 3D imaging model designed to identify features of blastocysts – the early stage of ...

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 ...

Please provide your email address to receive an email when new articles are posted on . Compared with in vitro culture, blastocyst formation from Invocell intravaginal culture performs slightly better ...

Newly created “blastoids” could give scientists a faster and simpler way to research embryonic development than using fertilized human eggs. Made of human stem cells, these blastoids are the most ...

At some point in our evolution, we lost the ability to activate a reproductive mechanism called embryonic diapause, which slows development, usually during the blastocyst stage. And so, unlike mammals ...
