Embryos' signals take multiple paths
Rice University scientists have found significant differences between the methods signaling pathways use to prompt cells to differentiate – that is, whether to become organs, bone, blood vessels, nerves or skin.

A so-called "jumping gene" that researchers long considered either genetic junk or a pernicious parasite is actually a critical regulator of the first stages of embryonic development, according to a new study in mice led ...

The factors that shape the destiny of a cell, like that of a fully formed person, remain something of a mystery. Why, for example, does one stem cell in a human embryo become a neuron rather than a muscle cell? And why does ...

For years, researchers have known that a gene called EAK-7 plays an important role in determining how long worms will live. But it remained unclear whether the gene had a counterpart in humans and – if it did – how that ...

Researchers at Karolinska Institutet in Sweden have managed to sequence the giant genome of a salamander, the Iberian ribbed newt, which is a full six times greater than the human genome. Amongst the early findings is a family ...

The more than 200 different types of human cells have the same DNA but express different ensembles of genes. Each cell type was derived from embryonic stem cells, which are called pluripotent stem cells because they can differentiate ...

Molecules called endosiRNAs help us avoid genetic chaos, according to a new study from a team at the Babraham Institute. Much of the human genome contains pieces of DNA called transposons, a form of genetic parasite. When ...
