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 ...

In this time-lapse video of an early C. elegans embryo, the first rounds of cell division are asymmetric: One daughter cell is larger than the other.The P cell lineage that eventually gives rise to ...

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 ...

Researchers have pinpointed a feature in the egg cell division process that plays a part in the chromosomal defects that cause miscarriage and birth defects, a new study suggests. The finding ...
