New findings offer insight into why some embryos fail to develop past zygotic genome activation (ZGA), pointing to an unexpected root of human infertility. A critical point in early development is ...

A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

A research team led by Associate Professor Hirofumi Nishizono and graduate student Masaki Kato from the Research Support ...

A system which replicates the womb lining (endometrium) with high biological fidelity has been developed by researchers at the Babraham Institute and used to listen in to the communication that ...

Integrated screening and CRISPR reveal eleven previously unknown factors essential for early embryo development. They showed ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

A new study led by Pr. Serge McGraw, researcher at CHU Sainte-Justine and professor at Université de Montréal, shows that the effects of alcohol exposure on an embryo prior to implantation in the ...
