Effects of metformin on autophagy and autolysosome in DN kidneys. Autolysosomes were detected by transmission electron microscope at the 4-week molding (a) or 12-week molding (b). The blue arrow indicates autophagy, and the red arrow indicates autolysosome. Scale bar represents 5 μm (left) and 1 μm (right) respectively. 4W: 4-week; 12W: 12-week; Met: metformin.
