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

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 ...

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

Using the fruit fly, scientists have constructed a complete and detailed single-cell map of embryo development. This research will also help scientists pursue questions like how mutations lead to ...

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 ...

A single-cell RNA atlas maps sea urchin development, revealing rare neuronal lineages and gene activity across stages, and ...

Scientists have identified key molecular events in the developing human embryo between days 7 and 14 -- one of the most mysterious, yet critical, stages of our development. Scientists have identified ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

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 ...
