A new "atlas" of early embryonic development in mammals suggests that the process is highly chaotic — but there is some method to the madness. When you purchase through links on our site, we may earn ...

The architecture of the body is not encoded as a formal blueprint; rather, it's the tightly orchestrated activation and ...

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, ...

A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in the body.

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...

Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers ...

New findings offer insight into why some embryos fail to develop past zygotic genome activation (ZGA), pointing to an unexpected root of human ...

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the "dark side" of the ...

A research team led by Associate Professor Hirofumi Nishizono and graduate student Masaki Kato from the Research Support ...

Mounting evidence from research on nematodes to mice indicate that a father's environment, such as what he eats or if he is exposed to stress or toxicants, can lead to metabolic and behavioral ...
