Scientists at the University of Pittsburgh have created living human cartilage grown on a laboratory chip. An innovative 3-D printing technique may allow scientists to create replacement cartilage for patients with osteoarthritis, which cause gradual degeneration of cartilage, which protects bony surfaces within a joint. Osteoarthritis affects many peopl...e, causing pain and loss of mobility, commonly in hips, knees and fingers.
"Osteoarthritis has a severe impact on quality of life, and there is an urgent need to understand the origin of the disease and develop effective treatments" said Rocky Tuan, Ph.D., director of the Center for Cellular and Molecular Engineering at the University of Pittsburgh School of Medicine. "We hope that the methods we're developing will really make a difference, both in the study of the disease and, ultimately, in treatments for people with cartilage degeneration or joint injuries.
