Localization of hyaluronectin in oligodendroglial cells.

Astroglia and oligodendroglia in primary cell cultures were identified by immunohistochemical staining with antiglial fibrillary acidic protein and anticerebroside antisera, respectively. The antiserum to hyaluronectin (HN) was utilized to show that this hyaluronic acid-binding glycoprotein was localized in the oligodendroglial cels. This is consistent with the recent finding that HN is localized in the node of Ranvier. Astroglia did not react with antihyaluronectin.
