Abstract

Osteoarthritis and Kartogenin Osteoarthritis is characterized by progressive breakdown of articular cartilage and affects over 25 million people in the United States. Mesenchymal stem cells (MSCs), which reside in healthy and diseased joints, are multipotent adult stem cells that are able to differentiate into a variety of cell types. Johnson et al. (p. 717 , published online 5 April) identified a small molecule, kartogenin, which was able to induce MSCs to differentiate into chondrocytes in vitro. When administered locally, kartogenin was efficacious in two animal models of osteoarthritis.
