Figure 1. Masson’s Trichrome staining of multiple organs collected from the WT and Neu1^–/– mice.

Fibrotic regions in the Neu1^–/– mouse are characterize by massive collagen deposition and therefore appear in blue (asterisks) (Images of WT and Neu1^–/– kidney, liver and skeletal muscle are from van de Vlekkert et al., 2019 ). Blue = collagens; Red = erythrocytes and cytoplasm; Dark purple/black = nuclei. Scale bars: kidney and liver = 100 μm, heart, lung and skeletal muscle = 200 μm.
