Effect of Content of Sulfate Groups in Seaweed Polysaccharides on Antioxidant Activity and Repair Effect of Subcellular Organelles in Injured HK-2 Cells

Figure 5

Change of lysosomal integrity after the damaged HK-2 cells were repaired by four DSPs with different −OSO₃H content. (a) Fluorescence microscope observation; (b) quantitative analysis. Red fluorescence represented unbroken lysosomes; (A) normal control; (B) damaged control; (C) DPY-1; (D) DGL-2; (E) DSF-3; (F) DUP-4. DSP concentration: 60 μg/mL; the damage concentration of oxalate: 2.8 mmol/L injury time: 3 h; repaired time: 12 h. indicates ; indicates .
