Comparison of Olig2 fluorescence intensity in OPCs, oligodendrocytes and astrocytes. a–c, a’–c’, a’’–c’’ Taking the olfactory bulb as an example, the Olig2 signal intensity in NG2⁺ OPCs is much stronger than that in CC1⁺ oligodendrocytes and S100β⁺ astrocytes. However, there is no significant difference of Olig2 intensity between oligodendrocytes and astrocytes. d Comprehensive quantitative comparison of fluorescence intensity of Olig2 in OPCs, oligodendrocytes, and astrocytes in the five CNS regions where Olig2⁺ astrocytes are enriched. OPCs has the strongest Olig2 signal. In TH, MB, and MY, there is no significant difference of olig2 signal between oligodendrocytes and astrocytes, but it has significant difference in MY region. In SC, no significant difference was detected between oligodendrocytes and astrocytes. Scale bars: 20 μm (a–c, a’–c’, a’’–c’’). All values are presented as mean ± SEM; One-way ANOVA test; **p < 0.01, ***p < 0.001, ****p < 0.0001
