and 4-cell stages than after the 8-cell stage of embryogenesis. The 4-cell embryo can now be seen as a transitional stage during which uniform DNA replication becomes sequential, while still ...

Researchers from the Kind Group have gained new insights into the mechanism behind the spatial organization of DNA within the ...

A stem-cell derived human embryo model showing blue cells (embryo), yellow cells (yolk sac) and pink cells (placenta). Scientists have grown an entity that closely resembles an early human embryo ...

Michael Barresi’s research interests are focused on how glial cells help wire the nervous system in the embryonic zebrafish brain. His lab discovered that astroglial cells provide a substrate for ...

Now - the clever bit. The cells on the inside layer of this very early embryo can make all of the cell types needed in your body. They're called stem cells. The stem cells continue to divide by ...

Dozens of labs around the world are striving to grow models of human embryos to study development, fertility and therapies.

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication.

The scientists measured the force required to change the shape of the cells by gently deforming each cell with a pipette. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of ...

Culturing pluripotent stem cells to replicate different stages of embryonic development allows researchers to more easily ...
