By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

When sperm meets egg, the start of life is not quiet. Under a special microscope, researchers have watched a tiny light show at fertilization. They see a microscopic flash at fertilization, a burst of ...

The team placed blastocysts—embryos 5-6 days after fertilization that were donated following IVF procedures—onto the ...

The University of Alabama at Birmingham health system has paused in vitro fertilization procedures following an Alabama Supreme Court decision due to fear of criminal prosecution and lawsuits, a ...

The University of Alabama at Birmingham health system has paused infertility treatments after the Alabama State Supreme Court ruled embryos created during in vitro fertilization should be legally ...

A new "atlas" of early embryonic development in mammals suggests that the process is highly chaotic — but there is some method to the madness. When you purchase through links on our site, we may earn ...

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 ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...
