The mechanisms that underlie early embryonic development in humans and cattle are very similar. Therefore, researchers argue that bovine embryos might well be a better model for early human ...

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 ...

Extracellular vesicles (EVs) and their cargo microRNAs (miRNAs) are important regulators of embryo development to the blastocyst stage and beyond. Before implantation can take place, hatching of ...

We know much about how embryos develop, but one key stage -- implantation -- has remained a mystery. Now, scientists have discovered a way to study and film this 'black box' of development. This new ...

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 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 ...
