Which immunomarker supports oligodendroglial differentiation in brain tumors?

Explanation:
Oligodendroglial differentiation is best tracked with a marker that directly labels the oligodendrocyte lineage. Olig2 is a nuclear transcription factor essential for oligodendrocyte development and is robustly expressed in oligodendroglial lineage cells and in many oligodendrogliomas. This makes it a precise indicator of oligodendroglial differentiation in brain tumors. In contrast, GFAP marks astrocytic differentiation, CD68 highlights microglia/macrophages, and S100 is a broader glial marker with less specificity for oligodendroglial lineage. Therefore, Olig2 provides the clearest evidence of oligodendroglial differentiation.
