Sirt3 Promotes Chondrogenesis, Chondrocyte Mitochondrial Respiration and the Development of High-Fat Diet-Induced Osteoarthritis in Mice

Cartilage is characterized by mature chondrocyte metabolic heterogeneity in a zone-dependent manner. In this study, we used single cell mRNA sequencing (scRNA-seq) to evaluate the corresponding functional and metabolic phenotypic heterogeneity of in vitro cultured primary juvenile murine chondrocytes Overall design: Single cell RNA sequencing to explore heterogeneity in primary cultured chondrocytes from knee joints of C57BL/6J mice
