11.   If the technique proves successful, researchers predict that precursor cells for bone could be used to replace tissue lost to cancer, osteoporosis, injury or dental disease.

12.   Technion scientists, for instance, already reported they have guided stem cells to transform into precursor cardiac cells that in the laboratory dish beat like a heart.

13.   The researchers induced the creation of the neurons in the neocortex of lab mice by triggering stem cells, or precursor cells, that already exist in the brain.
