The presence and distribution of the glutamate transporters, EAAC1, GLAST a
nd GLT-1, were examined in the adult bovine corpus callosum by means of Wes
tern blotting and immunohistochemistry. We found GLAST to be expressed in o
ligodendrocytes and in some astrocytes. GLT-1 was located throughout the pr
ocesses of fibrous astrocytes. In addition, EAAC1 was present in a small po
pulation of cells that are probably adult oligodendrocyte progenitor cells.
