Percentage of distinct oligodendrocyte precursor cells in the corpus callosum of the different experimental groups. a Confocal overview image of triple-labelled sections with antibodies against BrdU (red), GSTπ (blue) and NG2 (green). b Single confocal planes by z-stack co-labeling of BrdU⁺ with NG2⁺. c Single confocal planes by z-stack co-labeling of BrdU⁺ with GSTπ⁺. d The schematic detailed picture below shows areas analysed [39]. e, f The distribution of the BrdU⁺ cells between the different activity conditions at days 10 (e) and 42 (f).
