ted: One of these photos is of bone, the other is of cement foam. Which one is which? Yeah, we’re not that sure either. And that’s the point, says bone researcher David Pastorino, who — at TEDxBarcelona — shared how he and a team of researchers have come up with a crazy new way to regenerate bone with a material quite similar to the foam of a cappuccino. How? Well, doctors inject a foam cement made from calcium phosphate into the body after a big break and the foam mimics bone scaffolding so well that it tricks bone cells (osteoclasts and osteoblasts) into “eating” the material and replacing it with real bone. Magic? No, science! Learn more here» Bone grafting is becoming more and more important when we consider the aging world population. Bone cements today are not awfully different chemically from plexiglass and have not seen much change in fifty years or so. Technology like this may soon allow the regeneration of even the most severe breakages where the capacities of our bodies to heal are limited. -- source link
