Osteoarthritis (OA) is a degenerative joint disease characterized by articular cartilage degradation. Because OA has a multifactorial nature and complex interrelationship of the individual elements of a whole joint, there is a need for comprehensive therapeutic approaches for cartilage tissue engineering, which simultaneously address multiple aspects of disease etiology. In this work, we investigated a multifunctional carbohydrate-based drug candidate, tri-butanoylated N-acetyl-d-galactosamine analog (3,4,6-O-Bu3GalNAc) that induced cartilage tissue production by human mesenchymal stem cells (hMSCs) and human OA chondrocytes by modulating Wnt/β-catenin signaling activity. The dual effects promoted chondrogenesis of human MSC and reduced inflammation of human OA chondrocytes in in vitro cultures. Translating these findings in vivo, we evaluated therapeutic effect of 3,4,6-O-Bu3GalNAc on the rat model of posttraumatic OA when delivered via local intra-articular sustained-release delivery using microparticles and found this method to be efficacious in preventing OA progression. These results show that 3,4,6-O-Bu3GalNAc, a disease modifying OA drug candidate, has promising therapeutic potential for articular cartilage repair.
