There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, the Hiiragi ...

Healthy development. The researchers found that higher variability in cell division leads to a more optimal arrangement of cells within the embryo, which promotes healthy development.

We all start our lives as symmetric balls of cells. In humans, during the first few weeks after fertilization, embryonic ...

After a sperm fertilizes an egg, the totipotent cell divides into a zygote. As division continues, some cells divide into the growing mass, distinguishing cells that form the embryo (epiblast) from ...

Save guides, add subjects and pick up where you left off with your BBC account. If cells are removed from the embryo they will differentiate into any cell type. These are called embryonic stem ...

Life on Earth may have developed the ability to form embryos even before it grew the very first animals. A single-celled ...

The stem cells for embryonic stem (ES) cell research usually come from embryos left over from in vitro fertilization (IVF) clinics. In an IVF clinic, scientists combine a man’s sperm and a woman ...

“Using transparent 1-day old zebrafish embryos allows us to study a dynamic process like cell division inside a living organism,” said Holly Lovegrove, co-lead author of the study and a ...
