it is postulated that the gfap immunostaining within neoplastic cells of mullerian origin may be a reflection of the phenotypic diversity of intermediate filament proteins that can be expressed by malignant neoplastic cells , that the polypeptides of gfap may be heterogeneous , that there may be an ontogenic relationship between the cells of mullerian origin and neuroectodermal cells , or that this may represent neometaplasia of mullerian cells .
