Brain Histology - Adult Mouse Cortex
Most glial cells are much smaller than neurons. Their nuclei are generally much smaller than neuronal nuclei, and they rarely contain an easily visible nucleolus. Other aspects of their morphology are variable. The glial cytoplasm is, if visible at all, very weakly stained. Different types of glial cells cannot be easily distinguished by their appearance in this type of preparation. Most of the small nuclei located in the white matter of the CNS, where they may form short rows, are likely to represent oligodendrocytes. (text Blue Histology)
