Researchers at the University of Southampton have invented a new way to generate human cartilage tissue from stem cells. The technique could pave the way for the development of a much-needed new treatment for people with cartilage damage. Cartilage acts as a shock absorber in joints, but it is susceptible to damage through daily wear-and-tear, or trauma from sports injuries and falls.
Cartilage cells from the nasal septum can not only help repair cartilage injuries in the knee, they can also withstand the chronic inflammatory tissue environment in osteoarthritis and even counteract the inflammation – according to researchers from the University of Basel and the University Hospital Basel.
Joint cartilage usually regenerates very poorly. The matrix of cartilage (scaffolding) contains very few cells in deep layers. Moreover, joint cartilage is highly isolated: there are neither regenerative cells in the immediate vicinity that could migrate into the site of the defect and trigger repair, nor vessels that could transport regenerative cells to the cartilage. Unsurprisingly,…
Anyone needing a tomography gets the clearest possible images of an organ or other body structure slice by slice. But the further inside the potential problem lies, the more difficult it is to obtain high-resolution images in magnetic resonance imaging (MRI). An international team of scientists led by the University of Duisburg-Essen (UDE) has developed a high-frequency coil that allows for much…
Osteoarthritis affects more than 30 million adults and is the fifth-leading cause of disability in the United States.

There is currently no cure for osteoarthritis, but a group of scientists believe they’ve discovered a method through which a simple knee injection could potentially stop the disease’s effects. These researchers showed that they could target a specific protein pathway in mice, put it into overdrive and halt cartilage degeneration over time. Building on that finding, they were able to show that…
Researchers have designed a fluid that works like a luminous ink to obtain very sharp images of damaged tissues, organs and cartilages in diagnostic tests. This new compound, still in the laboratory phase, reduces adverse effects on the human body because it allows lower amounts to be injected and the dose to be targeted only at the affected area.
An algorithm that analyses MRI images and automatically detects small changes in knee joints over time could be used in the development of new treatments for arthritis. A team of engineers, radiologists and physicians, led by the University of Cambridge, developed the algorithm, which builds a three-dimensional model of an individual’s knee joint in order to map where arthritis is affecting the…
Contrary to popular belief, cartilage in human joints can repair itself through a process similar to that used by creatures such as salamanders and zebrafish to regenerate limbs, researchers at Duke Health found. This process could be harnessed as a treatment for osteoarthritis. Publishing in the journal Science Advances, the researchers identified a new mechanism for cartilage repair.
Researchers at Lund University in Sweden have investigated the link between osteoarthritis and mortality in an epidemiological study.
