Selenium Polysaccharide SPMP-2a from Pleurotus geesteranus Alleviates H₂O₂-Induced Oxidative Damage in HaCaT Cells

Figure 6

The effect of SPMP-2a on the ultrastructural changes of HaCaT cells exposed to H₂O₂. Transmission electron micrograms showed the ultrastructure of HaCaT cells before (a, d) and after H₂O₂ injury (b, e) or treated with 300 μmol/L SPMP-2a after the injury (c, f). Red arrows indicated the structure of mitochondria in the cytoplasm of HaCaT cells. Scale bar = 1 μm.
