Ultrastructure of human cerebral macroglia and microglia: maturing and hydrocephalic frontal cortex.
Fifteen human cerebral cortical biopsies from children treated for hycrocephalus by shunt operation and one non-hydrocephalic "control" biopsy specimen were studied by electron microscopy. Marked differences between the ultrastructural features of oligodendrocytes and microgliacytes in the maturing and hydrocephalic material and the ultrastructure of control and adult specimens were seen. Proliferation of oligodendrocytes was commonly discernible. Microgliacytes exhibiting plesomorphic vacuoles and bundles of microfilaments were often observed.
