Dose-dependence of GROβ-mediated neuronal survival. Granule cell neurons cultured for 6 days in 25 mM K+ medium were switched to 5 mM K+-containing medium and incubated in the presence of increasing concentrations of GROβ. After 24 h, the cells were lysed and nuclei counted as described in Materials and Methods. Data are expressed as number of surviving cells in 5 mM K+ medium vs 25 mM K+ (taken as 100%), and are the mean ± SEM of 6–15 independent experiments. Student's t test: **, P < 0.00001; *, P < 0.001.
