my question is very simple: I've purchased some human oligodendrocyte precursor cells from Sciencellonline, when I received the cells, I read something quite disappointing on the datasheet: do not subculture the cells since they won't proliferate in vitro. It implies I've just wasted a lot of money on a cell line which I can't even do any single experiment. Does anyone have worked on this cell line before? is there any limited passage numbers I can still try to risk? Thanks!
