Figure 6From: Amyloid-like aggregates of neuronal tau induced by formaldehyde promote apoptosis of neuronal cellsContrast microscope image of cells treated with amyloid-like tau. The same SH-SY5Y cells were imaged after incubated with tau deposits (2 μM) for 0, 24, 48 or 72 h (A-D). Cells were visualized by inverted contrast microscopy. Bar = 25 μm.Back to article page
