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 ...

Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late ...

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, ...

Researchers developed a method that visualizes gene activity across an entire embryo with high spatial detail. The resulting ...

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 ...

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 ...

Embryonic morphological development is delayed in live pregnancies ending in miscarriage, according to a prospective cohort study from the Netherlands. Among over 600 singleton pregnancies, those ...

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 ...

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 ...
