we have shown elsewhere that two cell surface proteins found on astrocytes , ran-2 and a5e3 antigen , and the intermediate filament protein , glial fibrillary acidic protein ( gfap ) , are all widely expressed in situ by nonmyelin-forming schwann cells in various nerves from adult rats , but not by myelin-forming schwann cells .
