Abstract

A highly radiosensitive glial cell type is described. The cell displays ultrastructural characteristics intermediate between the normal astrocyte and the light oligodendrocyte. It disappears from the cerebral cortex shortly after irradiation with doses ≥ 20 Gy. One year after this treatment, the cell type had reappeared but its frequency was still significantly lower than in age-matched sham-treated controls. The numbers of oligodendrocytes and microglial cells were also reduced at this time. The new cell element, called here a beta astrocyte, is present in significant numbers in the normal rat brain and its role as a multipotential reserve glial cell is discussed.
