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

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 ...

An international team of scientists led from Sweden's Karolinska Institutet has for the first time mapped all the genes that are activated in the first few days of a fertilized human egg. The study, ...

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.

The oviduct plays an indispensable role in mammalian reproduction by not only transporting gametes and embryos but also by providing a finely tuned microenvironment that supports fertilisation and ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive – particularly for egg-laying ...

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

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 ...

Understanding how cells differentiate during early embryonic development is crucial for advancing regenerative medicine and developmental biology. Pluripotent stem cells (PSCs) have been invaluable ...

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 ...
