MIT: New tissue scaffold regrows cartilage and bone

CAMBRIDGE, Mass.–MIT engineers and colleagues have built a new tissue scaffold that can stimulate bone and cartilage growth when transplanted into the knees and other joints.

The scaffold could offer a potential new treatment for sports injuries and other cartilage damage, such as arthritis, says Lorna Gibson, the Matoula S. Salapatas Professor of Materials Science and Engineering and co-leader of the research team with Professor William Bonfield of Cambridge University.

“If someone had a damaged region in the cartilage, you could remove the cartilage and the bone below it and put our scaffold in the hole,” said Gibson. The researchers describe their scaffold in a recent series of articles in the Journal of Biomedical Materials Research.

The technology has been licensed to Orthomimetics, a British company launched by one of Gibson’s collaborators, Andrew Lynn of Cambridge University. The company recently started clinical trials in Europe.
