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

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

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 ...

The first lineage decisions in mammalian embryonic development are made shortly after a wave of transcriptional activation that acts as a wake-up call for the sleeping embryonic genome to claim the ...

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 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 ...

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 ...

The first steps of human development—those that occur within the first few weeks of pregnancy—remain mysterious in many ways. Within a week of fertilization, human embryos form a blastocyst, which ...

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 ...

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 ...
