Abstract Heterogeneity is widely recognised across different cell types. Human oligodendrocyte progenitor cells (hOPCs), essential for myelination, exhibit considerable heterogeneity, which has not been fully characterised. In the current study, by examining the transcriptome of hOPCs at the single-cell level, three distinct subclusters were identified: PRE-OPCs, OPCs, and PRE-OLs. Single-cell RNA-sequencing and RNA-Scope detected high platelet-derived growth factor receptor alpha ( PDGFRA ) expression. PDGFR-α + hOPCs exhibited greater myelination, migration, and proliferation capabilities compared to both unsorted hOPCs and PDGFR-α – hOPCs. These enhanced functions may be associated with the activation of the PI3K-AKT-mTOR and TGF-β signalling pathways, which support oligodendrocyte differentiation.
