RT Journal Article T1 Standardizing single-cell approaches to osteoarthritis: Toward a comprehensive cellular atlas A1 Delgado-Sánchez, Iván A1 Fernández-Pozo, Noé A1 Durán-Jimenez, Iván Jesús K1 Artrosis K1 Citología K1 Acido ribonucleico AB Osteoarthritis (OA) is a degenerative joint disease marked by progressive cartilage degradation and complexcellular heterogeneity. In recent years, single-cell RNA sequencing (scRNA-seq) has emerged as a powerfultool for dissecting the cellular composition of the osteoarthritic joint. However, constructing a complete andcoherent picture of the OA single-cell landscape remains challenging, akin to assembling a puzzle frommultiple sets, each with pieces of varying shapes and sizes. This editorial outlines the next steps in advancing single-cell research in OA, emphasizing the need for standardized cell type annotations andcomprehensive, integrative access to both historical and newly generated datasets.
