SRP356450 PRJNA800013 GSE194258 Olig2 ablation in immature oligodendrocytes does not enhance CNS myelination and remyelination The oligodendrocyte (OL) lineage gene Olig2 persistently expresses throughout oligodendroglial development and required for oligodendroglial specification and differentiation. Here, Together, by leveraging multiple immature OL-expressing Cre lines at different stages, we demonstrate that Olig2 is required for differentiation and myelination of immature OL and myelin repair and raise fundamental questions about the previously proposed role for Olig2 in opposing OL myelination, while highlighting the importance of using Cre-dependent reporter for lineage tracing in studying cell fate transition.
