High Glucose Induces Autophagy through PPARγ-Dependent Pathway in Human Nucleus Pulposus Cells

Figure 6

It showed that the autophagy in NP cells increased when the agonist was added to the high glucose medium, while it decreased when the antagonist was added ((G, I) light microscope; (H, J) fluorescence microscope. (G) and (H) represent as 0.2 M high glucose + agonist; (I) and (J) as 0.2 M high glucose + antagonist, resp.).
