Unlike less versatile muscle or nerve cells, embryonic stem cells are by definition equipped to assume any cellular role. Scientists call this flexibility "pluripotency," meaning that as an organism develops, stem cells must be ready at a moment's notice to activate highly diverse gene expression programs used to turn them into blood, brain, or kidney cells.
