Good News for Bad Knees
We can now grow cartilage:
Tissue engineering can effectively fix damaged knee cartilage, researchers have shown for the first time. Cartilage cells donated by patients were grown on scaffolds in the lab before being implanted back into their knees. More than a year later analysis showed the cartilage had matured successfully, even in patients with osteoarthritis.
Tissue engineering uses a mixture of biology, chemistry and materials science to grow tissues in the lab just like those in the body. Until recently, most research has taken place in the lab.
