Cartilage is a flexible biological tissue that provides padding where bones come together in a joint. A new method for 3D printing cartilage is being proposed as a method for treating osteoarthritis, a disease marked by its gradual disintegration of cartilage.
In the past, several different methods for 3D printing cartilage and other human tissues have been studied and tested but many of the most promising ones require UV light to cure the bioink, however the UV light itself can be harmful to living cells.
Citing the Federation of American Societies for Experimental Biology, NanoWerk has highlighted research into a new method for 3D printing cartilage developed by Rocky Tuan, Ph.D., director of the Center for Cellular and Molecular Engineering at the University of Pittsburgh School of Medicine, member of the American Association of Anatomists and the study’s senior investigator. In contrast to the use of UV light, Dr. Tuan’s method for 3D printing utilises visible light and thus represents a significant step forward in developing a potential cure for a disease that affects up to 50% of the global population over 60 years of age, causing severe pain and loss of mobility in joints.
“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 Dr. Tuan. “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.” … (Read more)
