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 ...

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 ...

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, ...

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 ...

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

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 ...

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 ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

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 ...
