CSF1R inhibitor treatment did not alter oligodendrocyte progenitor cells (OPCs) in the control or ⁴He-irradiated brains. a–d and a1 Representative confocal z stacks for the OPC marker NG2 (magenta; nuclear counter stain, DAPI, blue) is shown for the 0 Gy and 30 cGy irradiated groups receiving either control chow or PLX5622 chow. e–f Neither ⁴He irradiation nor PLX5622 treatment alter the number of NG2⁺ cells or the gross immunoreactivity. Data are presented as mean ± SEM (n = 4/group). Scale bars: 50 μm, a–d; 5 μm a1
