Hoffman modulation contrast microscopy images demonstrating the effects of ouabain on human and rat astrocytes. Human and rat astrocytes were incubated for 24 h in DMEM containing 10% fetal bovine serum and 20 and 5,000 μM ouabain for human and rat cells, respectively. These representative images were captured using an Olympus IX-71 setup with 100× magnification.
