Many four-legged animals go through embryonic stages that have similar features -- gill arches, a notochord, segmentation, and paddle-like limb buds -- as they develop into different adults.

Closely studied, stem cell lines might give scientists new clues about the growth factors that drive tissue differentiation from the earliest embryonic stage forward. This would permit new ...

How cells utilize electric fields to guide their migration during embryonic development. As an embryo develops, cells ...

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 ...

Old viral DNA, once thought to be gone forever, is reactivated in mammalian embryos, with each species showing unique ...

These are called embryonic stem cells ... hope of a cure as stem cell therapies are only in their developmental stages.
