Human Embryonic Stem Cell -- Derived Bone Tissue Closes Massive Skull Injury

There are mice in Baltimore whose skulls were made whole again by bone tissue grown from human embryonic stem cells (hESCs).Healing critical-size defects (defects that would not otherwise heal on their own) in intramembraneous bone, the flat bone type that forms the skull, is a vivid demonstration of new techniques devised by researchers at John Hopkins University to use hESCs for tissue regeneration.
