title: Focal ependymal differentiation in the choroid plexus of human newborn brain confirmed by immunohistochemistry with monoclonal antibodies.
abstract: Ependymal proliferation ["Ependymzotten", G. Becker, Beitr Pathol Anat Allg Pathol 103:457-477 (1939)], found in choroid plexus of newborns, can be made easily visible by immunostaining with antiglial fibrillary acidic protein (GFAP) antibodies. The expression of both GFAP and cytokeratin is an unusual feature of these structures.
