The new solution could result in a minimally invasive, practical, and inexpensive approach for repairing cartilage and preventing osteoarthritis, the study noted."We are creating an (injectable, bioactive) hydrogel that can repair cartilage damage, regenerate stronger cartilage, and hopefully delay or eliminate the development of osteoarthritis and eliminate the need for total knee replacement," said first author of the study Yin Yu from the University of Iowa.

The researchers had previously identified precursor cells within normal cartilage that can mature into new cartilage tissue. This was a surprising discovery because of the long-held assumption that cartilage is one of the few tissues in the body that cannot repair itself.The team also identified molecular signalling factors that attract these precursor cells, known as chondrogenic progenitor cells (CPC), out of the surrounding healthy tissue into the damaged area and cause them to develop into new, normal cartilage.
