embryonic stem cells are pluripotent—they can become virtually every kind of human cell. The cells being nurtured here are direct descendants of the ones James Thomson isolated seven years ago.

Stem cell research is still a new field within biology. Many big advances, like the discovery of human embryonic and tissue stem cells, have been made only during the past 25 years. Thanks to stem ...

Scientists have officially grown a notochord—the tissues that act as the “GPS for the developing embryo” by guiding the ...

This important study reveals a role for IκBα in the regulation of embryonic stem cell pluripotency. The solid data in mouse embryonic stem cells include separation of function mutations in IκBα to ...

Their study, published in the journal Developmental Cell, indicates that transposable elements are critical to ensure that ...
