The "modest" blastocyst development rate likely stems from two factors, the study authors wrote in their paper. For starters, chromosomal abnormalities likely stopped the fertilized eggs from dividing ...

A global review highlights embryo metabolomics in spent culture media as a promising non-invasive method for embryo selection ...

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 ...

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 ...

It turns out that a gene called LTR5Hs activates a gene that affects the growth of an embryo and the proliferation of stem ...

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 ...

Researchers have very limited opportunities to study the earliest stages of human development, but a groundbreaking discovery led by a team in Australia will now provide them with a valuable new model ...

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...

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 ...
