in order to explain the presence of detectable gfap in developing ependymal cells and its absence in mature cells , it is proposed that either the synthesis of detectable amounts of gfap occurs only at a stage of ependymal cell maturation , or that the intermediate filaments assembled in developing ependymal cell are antigenically distinct form those of the mature cells .
