Why do Olig2+/Nestin+ cells show reduced proliferation while Olig2+/PDGFRα+ cells remain unchanged in aged TBI mice?

OPEN

The differential response of OPC subpopulations based on spatial origin suggests distinct regulatory mechanisms, but this selective vulnerability is not mechanistically explained. This gap limits understanding of which OPC populations to target therapeutically in aged TBI patients.
