Dexamethasone does not affect cell viability of primary neurons.

<p>(<b>A</b>), Dexamethasone (DEXA) was applied to rodent hippocampal neurons for 48 hs and cell death was determined by PI staining (PI, propidium iodide, left column, Scale bar represents 200 μm). Right, white light microscopy indicates morphological integrity of neurons following DEXA treatment. Scale bar 100 μm (<b>B</b>), Neurons were cultured at various concentrations of DEXA for two days and cell viability was determined by measuring the PI signal intensity.
