Hyperdiploid to pentaploid with several markers; the stemline chromosome number is near triploid with the 2S component occurring at 9.8%., Five markers [t(11;5), t(8q;4), t(19;?18), M1 and M2] were common to most S metaphases. One chromosome 4 could be found in every S metaphase. Chromosome composition was very uniform among cells.

This is one of a number of cell lines derived from malignant gliomas (see also ATCC HTB-14 and ATCC HTB-15 ) by J. Ponten and associates from 1966 to 1969.­
