title: C-type virus particles in the transplantable mouse bladder tumour FCB grown in vitro.
abstract: Electron microscopic studies were made on an in vitro cultured cell line obtained from the FCB transplantable murine bladder tumour. The cells exhibited a loss of differentiation compared with solid tumour and the presence of C-type virus particles, many in the process of budding. The possible relation of this virus to murine bladder carcinogenesis is discussed.
