Osteoarthritis (OA) is the most common form of arthritis, in which cartilage is irreversibly degraded, causing severe pain and disability. Current therapeutic strategies cannot repair damaged cartilage. We evaluated the repair potential of selected chondrogenic clonal MSCs (sC-MSCs) by delivering them into the injured cartilage site in a collagenase-induced OA model in Cynomolgus monkeys. In vitro characterization showed that the isolated monkey sC-MSCs and polyclonal MSCs (P-MSCs) expressed mesenchymal stem cell markers and could differentiate into chondrocytes. The articular cartilage lesions in animals were treated with normal saline (NS), autologous P-MSCs and sC-MSCs, respectively, by direct delivery. The clinical parameters, radiographic images, histological and immunohistochemical examinations at weeks 8, 16 and 24 post-treatment demonstrated that the abrasions of articular cartilage were significantly improved and repaired by MSC-based treatment, particularly in the sC-MSC-treated group, which displayed consistently higher histological scores than those of other groups. In summary, treatment with sC-MSCs can effectively improve the healing of cartilage lesions in the Cynomolgus monkey collagenase-induced OA model. Due to the genetic proximity of monkey and human, the therapeutic strategy presented in this study will have broad applications in clinical practice. Copyright © 2013 John Wiley & Sons, Ltd.
