Chondrocytes are specialized cells that are essential for cartilage maintenance and repair, and their dysfunction is central to the development of joint diseases like osteoarthritis (OA). However, the cell heterogeneity of chondrocytes in human articular cartilage is still not well defined, which hinders understanding of the pathogenesis of OA. This research, published in the Genes & Diseases journal by a team from the Harbin Institute of Technology, Southern University of Science and Technology, Shenzhen University, Guangxi University of Chinese Medicine, Guangdong Medical University, and the University of Chinese Academy of Sciences, employs Single-cell RNA sequencing (scRNA-seq) to uncover distinct subpopulations…
