Sox9, a master regulator of cartilage formation, switches its target genes dynamically during embryonic limb development ...

Animal embryos go through a series of characteristic developmental stages on their journey from a fertilized egg cell to a functional organism. This biological process is largely genetically ...

New research suggests DNA may not need activation, challenging a long-held idea about how life began and reshaping ...

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 ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...

NEW YORK (Reuters Health) - Women undergoing assisted reproduction may be interested to learn that transfer of a "blastocyst-stage" embryo increases their odds of having a boy. Blastocytes are the ...

Scientists have created the world’s first lab-grown “synthetic embryo,” a groundbreaking moment in science that has reignited a fierce ethical debate. Led by molecular geneticist Joseph Hanna, a team ...

How can we reliably and objectively characterize the speed and various stages of embryonic development? With the help of artificial intelligence! Researchers present an automated method. Animal ...
