Chondrocytes differentiation and immune cells interactions of Endplate Cells in Human Intervertebral Disc Degeneration
Ontology highlight
ABSTRACT: We performed the single-cell RNA-sequencing analysis (scRNA-seq) of the cells focusing on degenerative human endplates. By unsupervised clustering of the 8,534 single-cell based on the gene expression, we identified nine distinct cell types. We employed Gene ontology (GO) analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways analysis, and the single-cell regulatory network inference and clustering (SCENIC) to determine the enriched pathways and transcriptional activities across seven chondrocyte subpopulations. Furthermore, two cell fates of chondrocyte differentiation were found by trajectory analysis, one was enriched in inflammation-related genes, and the other was related to extracellular matrix (ECM). Additionally, the intercellular interactions of MAs and chondrocytes, T/NK cells and chondrocytes were examined by ligand-receptor pairs analysis, showing the important regulative function of FN1 from MAs and CD74 from T/NK cells during endplate degeneration.
