abstractText | PDGFRalpha, specifically expressed by immature oligodendrocyte progenitor cells (OPCs) in the CNS, plays a critical role in OPC proliferation and migration. However, it has been uncertain whether all cells of oligodendrocyte lineage are derived from the PDGFRalpha-expressing OPCs. In the present study, we uncovered a PDGFRalpha-independent oligodendrocyte lineage in the developing cortex. This OPC subpopulation originates from the local ventricular/subventricular zone after birth and contributes to the earliest mature oligodendrocytes in the cortex. PDGFRalpha signaling does not regulate the generation and differentiation of cortical OPCs. Fate-mapping studies in the PDGFRalpha(CreER); Sox10-GFP/tdTom double-transgenic mice of either sex have further corroborated the PDGFRalpha-independent oligodendrocyte lineage. This study provides additional missing genetic evidence for PDGFRalpha-independent oligodendrocyte lineage in the developing hindbrain.SIGNIFICANCE STATEMENT This is the first report of a subpopulation of oligodendrocyte lineage in the developing mouse cortex independent of PDGFRalpha signaling. These oligodendrocyte progenitor cells are generated from the local ventral ventricular zone/subventricular zone after birth, and contribute to the earliest mature oligodendrocytes in the cortex. |
