title: Particles resembling oncornaviruses. Spontaneous release from cultured meningioma cells.
abstract: A cell culture from thoracic cord meningioma tissue obtained at surgery was maintained for several passages in cell culture. These cells spontaneously released particles with an RNA of high-molecular weight (90S to 95S) and a density similar to that of type C oncornaviruses. The implications of these results and similar findings by others are discussed.
