Abstract:

The etiology and pathogenesis of osteoarthritis (OA) remain unclear and the main pathological changes are cartilage degeneration, synovial inflammation and subchondral bone remodeling. Currently, research on the mechanism of OA still has many limitations and inaccuracies, such as ignoring the significance of individual cell heterogeneity in the development of OA. Bulk RNA sequencing obtains the average gene expression level of all cell populations or a group of cell populations in the tissue and average transcriptome data. Single cell RNA-seq (scRNA-seq) obtains the gene expression level of individual cell. It plays an important role in discovering cellular heterogeneity and transcriptome analysis of trace samples, and provides new strategies for understanding the pathological mechanisms of OA at the molecular level and discovering potential therapeutic targets. This article summarized the core steps of scRNA-seq technology and its research and application in articular cartilage of OA.
