tsjt60 cells are g0-specific temperature-sensitive mutants of the cell cycle from fischer rats i.e. , they grow exponentially at both 34 degrees and 39.5 degrees c , but when stimulated with fetal bovine serum ( fbs ) from the resting state ( g0 ) they enter s phase at 34 degrees c but not at 39.5 degrees c .
