title: [Transformation, in vitro, of cerebral hamster cells by polyoma virus].
abstract: A cell line called HCxPy was obtained in vitro by transformation of dissociated hamster brain cell cultures by polyoma virus. The first foci of transformed cells became evident 90 to 120 days after viral infection. This cell line is now at the 46th passage. The cells appear tumorigenic for hamsters after subcutaneous and intracerebral injection. They carry the polyoma virus T and cell surface antigens. Good evidence for astrocytic differentiation can be found by morphological examination of the tumours and of the cultured cells.
