Web29 de mai. de 2024 · OPC cell counts were performed manually on images using a constant field of view (FOV) of 200 µm × 200 µm centered on the CA1 area, and data expressed as OPC density per mm 2; data from two sections per mouse were averaged, to provide a final n = 4 mice per treatment group, on which statistics were performed. WebOne determinant of OPC density could be the necessity to generate OLs. Consistently, OPC density is low in CNS regions where unmyelinated axons predominate such as the molecular layer of the cerebellar cortex (Givogri et al., 2002; Sun et al., 2024). However, in other regions the distribution of OPCs does not match that of OLs.
