Immunohistochemical study of fibronectin in hemangioblastomas and hemangiopericytomas

Eight hemangioblastomas and two hemangiopericytomas were studied using indirect immunoperoxidase stains for fibronectin (FN) and glial fibrillary acidic protein (GFAP) in formalin-fixed, paraffinembedded surgical specimens. Stromal cells in hemangioblastomas were GFAP-negative and showed variable FN expression, while GFAP-positive cells were FN-negative… CONTINUE READING
