Columbia College of Dental Medicine researchers have identified stem cells that can make new cartilage and repair damaged joints.
The cells reside within the temporomandibular joint (TMJ), which articulates the jaw bone to the skull. 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.
The findings were published on October 10 in Nature Communications.
“This is very exciting for the field because patients who have problems with their jaws and TMJs are very limited in terms of clinical treatments available,” said Mildred C. Embree, DMD, PhD, assistant professor of dental medicine at Columbia University Medical Center (CUMC) and the lead author of the study. Dr. Embree’s team, the TMJ Biology and Regenerative Medicine Lab, conducted the research with colleagues including Jeremy Mao, DDS, PhD, the Edwin S. Robinson Professor of Dentistry (in Orthopedic Surgery) at CUMC.
