Glia-specific antigen in the intracranial tumors. Immunofluorescence study

Summary26 gliomas and 14 non-glial tumors were examined for the presence of nervous system specific antigen (CGSA) to assess the antigenic properties of neoplastic tissue in relation to histogenesis and degree of differentiation of tumors. Double layer immunofluorescence (IMF) technique was used for the cellular localization of the antigen.CGSA was found in the cytoplasm of normal, reactive and neoplastic neuroglial cells. Well differentiated …
