Effect of ammonium salts on the morphology of glutamine-starved Sp2/0-Ag14 cells. Cells were deprived of l-glutamine (−Gln) for 3 h in the presence of 5 mM ammonium salt/sodium salt or an equivalent volume of PBS. Cultures in which Gln was added at the start of the experiment (+Gln) were included as controls. magnification: ×400
