Lithium Improves Survival of PC12 Pheochromocytoma Cells in High-Density Cultures and after Exposure to Toxic Compounds
Figure 5
Ultrastructural analysis of lithium-treated PC12 cells. Membrane-delimited vacuoles in the cytoplasm with the characteristic features of autophagic vacuoles (arrows) are present in untreated cells (a) and more numerous in lithium-treated sample (b). Scale bars = (a): 1 μm; (b): 0.4 μm.
