Stem Cell Signal Drives New Bone Building

In experiments in rats and human cells, Johns Hopkins Medicine researchers say they have added to evidence that a cellular protein signal that drives both bone and fat formation in selected stem cells can be manipulated to favor bone building. If harnessed in humans, they say, the protein — known as WISP-1 — could help fractures heal faster, speed surgical recovery and possibly prevent bone loss due to aging, injury
