Establishment and characterization of a new human glioblastoma cells line, NYGM
2008
A cell line designated NYGM was established from a human cerebral glioblastoma multiforme (GBM) obtained from a 75-year-old Japanese woman. The cell line has grown slowly without interruption and has been propagated continuously by
serial passages(more than 80 passage) during the past 3 years. The cultured cells were fusiform or polyhedral in shape. The population
doubling timewas 24 hours. The chromosomal number varied between 77 and 88, with modal chromosomal number of 84. NYGM cells concomitantly expressed MET
receptor tyrosine kinase(a product of
c-metprotooncogene) and its ligand HGF/SF (
hepatocyte growth factor/scatter factor), as well as HGF activator and HGF activator inhibitors. The cells might be useful for the study of pericellular regulation of HGF/SF-MET signaling and HGF advation of GBM cells.
