title: Induction of GFAP production in human glioma lines grafted into the anterior chamber of the rat eye.
abstract: Three established glial fibrillary acidic protein (GFAP)-negative cell lines from human gliomas were transplanted to the anterior chamber of the rat eye. Short-term survival was seen with all transplants. The cells expressed GFAP following transplantation. For comparison, 4 GFAP-positive cell lines were transplanted. With grafting of 5000 cells of any of 6 bipolar cell lines, the transplanted cells could be seen to develop multiple, slender processes reminiscent of mature astrocytes. When 50,000 cells were grafted, vascularized cell mats covering the corneae were seen. The induction of GFAP production and the phenotypic changes were interpreted as signs of differentiation induced by the new environment. All transplanted cells were rejected after 8 weeks.
