Summary

A glial cell subtype, previously classified as a beta astrocyte on the basis of its ultrastructural and radiobiological characteristics, has now been shown to represent the most mitotically active component of the glial population in the grey matter of the cerebral cortex of the young adult rat. The labelling index of 0.83% was evaluated using semithin sections. A role for beta astrocytes as macroglial precursors is supported by the present observations. However, the mechanisms responsible for the intermediate radiosensitivity of these elements remain uncertain.
