Location is everything for plant cell differentiation

While the fate of most human cells is determined by their lineage—for example, renal stem cells go on to form the kidney while cardiac progenitor cells form the heart—plant cells are a little more flexible. Research shows that although they undergo orderly division during growth, the fate of plant cells is often determined by their location in the growing plant rather than how they started out. Intriguingly, this suggests that plant cells recognize where they are and can alter gene activity in response to their location.
