title: Establishment of a human glioma cell line bearing a homogeneously staining chromosomal region and releasing alpha- and beta-type transforming growth factors.
abstract: A human glioma cell line (YKG1), which was positively identified for glial fibrillary acidic (GFA) and S-100 proteins, was established from a surgical specimen of a patient with glioblastoma. Chromosome analysis of the cells revealed a homogeneously staining region (HSR) on a marker chromosome. The assay for transforming growth factors (TGFs) in the conditioned medium of the cell line revealed that it contained high levels of alpha- and beta-type TGFs, which might regulate the growth of glioblastoma and influence on the peritumoral tissues.
