β¦ Synopsis
We investigated continuous production of Inoue-Melnick virus (IMV) in the MG-1 cell line, established from human meningioma. The infectious virus, identified as a type 1 virus, was mostly recovered extracellularly. Assay of MG-1 cells as infective centers indicated that most of the cells were capable of producing infectious virus. By immunofluorescence, more than 90% of the cells were found to have IMV-associated cytoplasmic antigen(s) (IMCA).

Inoue-Melnick virus (IMV) was isolated from six of seven human meningiomaderived cell cultures, while the virus was not isolated from six other brain tumor cell cultures.
