Oligodendrocyte-related NOGO-A expression within axon tracts. H&E of an axon tract (arrow) within the E10 chick brain preceding oligodendrocyte related myelination. Section in situ hybridization (sISH) of the fiber tract shows NOGO-A expression to be absent within the tract but present in surrounding neurons. H&E of a myelinated axon tract (arrow) at E20. ISH shows oligodendrocyte related NOGO-A expression within the fiber tract. Scale bars 250 μm.
