Cartilage and bone development: Three paths to skeleton formation

In vertebrates, the skeleton of different regions of the body arises from different precursor cells. Researchers have now discovered that these skeletal cells do not just differ in their developmental origin, but also in their gene regulation -- which may be a key to the vertebrates' evolutionary success story.
