Fig. S13 Liver structure is not altered in acute organophosphorus poisoning in zebrafish. Normal hepatic structures and normal hepatocytes are observed both in 8 days post-fertilization control (A), grade 1 (B), grade 2 (C) and grade 3 (D) zebrafish larvae. Hepatocyte nuclear size may not be homogeneous in the same fish and darker nuclei in D correspond to erythroblasts/erythrocytes. The presence of lipid droplets (white spherical structures) is a normal observation corresponding to yolk remnants, and their number may not always be homogeneous in fish from the same batch. Scale bar: 80 µm.
