Nanoscale scaffolds spur stem cells to cartilage repair

A spun 3-D scaffold of nanofibers did a better job of producing larger quantities of and a more durable type of the cartilage protein than flat, 2-D sheets of fibers did.

Johns Hopkins tissue engineers have used tiny, artificial fiber scaffolds thousands of times smaller than a human hair to help coax stem cells into developing into cartilage, the shock-absorbing lining of elbows and knees that often wears thin from injury or age.

Reporting online June 4 in the Proceedings of the National Academy of Sciences, investigators say they have produced an important component of cartilage in both laboratory
