Abstract:

Single-cell RNA sequencing(scRNA-seq)technology,a powerful tool able to analyze gene expression at single-cell resolution,has been widely used in periodontitis research in recent years,greatly advancing the understanding of cellular heterogeneity and mechanisms of pathological progression in periodontal tissues.Herein,we review the development of scRNA-seq technology from early attempts to maturity and diversification,and focus on the present progress of its application in periodontitis research.By constructing a single-cell atlas of periodontal tissues,the researchers revealed cellular heterogeneity and identified key cellular subpopulations and molecular markers associated with disease progression and repair.Cellular heterogeneity analysis and pseudotime analysis further elucidated the functional properties of different cells in periodontitis and the dynamic course of the disease.The cellcell communication analysis resolved the intercellular signaling network,which provided new perspectives for disease diagnosis and treatment.These studies revealled the periodontitis -associated cell subpopulations and the key molecular mechanisms,which provided important clues for precise diagnosis and targeted treatment of the disease.In addition,this review provides an insight into the future direction of scRNAseq in periodontics,including spatial transcriptomics,multiomics integration,the application of big data and artificial intelligence,and the prospects for precision diagnosis and treatment.Although scRNA-seq still faces challenges such as high cost and data complexity,through technical optimization,data integration and interdisciplinary cooperation,this technology is expected to further advance the development of periodontitis research and strongly contribute to precision medicine and health management.

Key words: Single-cell RNA sequencing, Spatial transcriptomics, Multi-omics, Periodontitis, Artificial intelligence
