Application of single-cell RNA sequencing in probing oligodendroglia heterogeneity and neurological disorders

In the central nervous system, oligodendrocytes are highly specialized myelinating glial cells that originate from oligodendrocyte precursor cells. In the past, research centered on the oligodendrocyte development, myelination, and the role of oligodendrocyte lineage in neurological disorders. The emerging single-cell RNA sequencing technology is a new tool to specifically identify cell-types at the transcriptome level, and recently have also been used to investigate oligodendrocyte lineage-related issues. In this review, we summarize the recent developments of single-cell RNA sequencing technologies and their application in the oligodendroglia heterogeneity and neurological disorders, thereby providing new ideas and references for the utilization of single-cell RNA sequencing technology in the research field of oligodendrocyte lineage and neurological disorders.
