The BBC delivers more good news on the bone regeneration front: "We have shown that we can grow predictable volumes of bone on demand. And we did so by persuading the body to do what it already knows how to do. ... The technique uses the body's own natural wound-healing response, which allows broken and fractured bones to knit together, by creating a space around the healthy bone and encouraging growth." This is a clever technique, but still unproven in humans as the article points out. Still, it is promising to see so many different tactics in present day bone regeneration research. That is a good sign for the future, especially for those suffering from the age-related bone loss of osteoporosis.
