According to Science Daily scientists at Columbia University College of Dental Medicine have experimented with stems cells which have the ability to become any type of cell in the body, to boost cartilage.
Researchers have identified stem cells in the jaw bone that can make new cartilage and repair damaged joints. They used cells specifically for the temporomandibular joint (TMJ), which connects the jaw bone to the skull, to build a specific type of cartilage known as fibrocartilage which is also found in the knee and spine.
When the stem cells were manipulated in animals with TMJ degeneration, the cells repaired cartilage in the joint. A single cell transplanted in a mouse spontaneously generated cartilage and bone and even began to form a bone marrow niche.
