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 ...

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 ...

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 ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

Research shows how the curved shape of a zebrafish egg sets cell division timing, gene activation, and early cell fate ...

Over 130 mammal species can delay embryonic development, giving their offspring the best possible chance of survival in ideal ...

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 ...

SCDIRB copy 39088019634765 not included in the Bibliotheca Beckwithiana (unpublished). SCDIRB copy has bookplate: Smithsonian Libraries: The Beckwith-Browning-Peterson Teratology Collection. SCDIRB ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

Researchers have discovered a key transition in early embryonic development is facilitated by decreasing levels of a viral protein inserted into the DNA of our early animal ancestors. Researchers at ...
