Abstract

A permanent cell line, BO-101, was derived from a classic vermian medulloblastoma in a 9-year-old child. This line grew in vitro in adherent cultures and grew in athymic mice as serially transplantable intracranial and subcutaneous xenografts. Intracranial neoplasms grew as masses of small cells, which focally showed large cells with intense immunoreactivity for desmin, myoglobin and alpha-striated actin. The rhabdomyoblastic nature of these cells was confirmed ultrastructurally. The primary neoplasm showed immunoreactivity for synaptophysin, neuron-specific enolase and vimentin. A large panel of monoclonal antibodies and antisera against neuronal and glial antigens failed to show glial and neuronal immunoreactivity in the cell culture and xenografts. Despite the marked genotypic and phenotypic differences, the original neoplasm and the cell line share a common chromosomal marker del (12) (p 13.1). The BO-101 line differs phenotypically and genotypically from previously established medulloblastoma cell lines and further supports the heterogeneous biologic properties of the cell populations that constitute these neoplasms.
