Biologists have long puzzled over how organs develop into their final shapes, and the nearly transparent bodies of young sea ...

Getting it over the finish line was a labor of love—and now, more than five years after her death, the lab of former Sloan ...

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 ...

Researchers led by developmental biologist Kathy Niakan at the University of Cambridge have used base editing in human embryos to learn more about human embryonic development. By deactivating a gene ...

Two separate research teams used base editing to make single-nucleotide changes in human embryos this month, targeting genes ...

Researchers at the Institute for Bioengineering of Catalonia (IBEC) in collaboration with the Dexeus University Hospital have captured unparalleled images of a human embryo implanting. This is the ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

"Guinea pigs can become a valuable model for understanding how early disturbances in embryonic development can affect health later in life. Since guinea pig development mirrors that of humans better ...

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early ...
