Figure 7: Hematoxylin and eosin staining (H&E) and Picrosirius red (PSR) staining of the decellularized ECM.

H&E shows that all the cells have been removed. In the PSR staining images, the ECM from the chow-fed mice revealed a well-organized network, and in contrast, mice on fast-food diet (FFD) showed denser collagen fibers. Z-volume (thickness) = 6 μm. Scale bar = 100 μm.
