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 ...

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development? A new imaging method makes it possible to visualize the ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

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 ...

The reproductive biology of lampreys is of special interest given the group has retained many developmental features reminiscent of the earliest vertebrates. Herein I report spawning behavior in the ...

Consider the crustacean Parhyale hawaiensis, a tiny crustacean with some interesting attributes. “It’s been called a ‘living Swiss army knife,’” said Dillon Cislo, the lead author of a study that ...

A team of scientists has identified an unexpected embryonic "starting point" for several brown-fat depots: a small cell niche around the dorsal aorta. Using a combination of time-controlled genetic ...

Though more than 8 million babies have been born through in vitro fertilization (IVF), 70% of IVF implantations fail. As IVF is becoming a more common route to pregnancy in cases of infertility, there ...

When the zygote, or the fertilised egg, starts to develop, the soon forming inner cell mass, a cluster of cells that will eventually develop into the individual, retains its pluripotent stem cell ...
