Selenomethionine protects hematopoietic stem/progenitor cells against cobalt nanoparticles by stimulating antioxidant actions and DNA repair functions
Figure 3. Both CoNPs and SeMet led to the activation of γH2AX, but SeMet did not cause DNA damage. CD34+ HSC/HPCs were treated with 10 μM SeMet and 200 μM CoNPs, alone or in combination. (A) The phosphorylation level of H2AX (γH2AX) was determined by IF analysis. DNA damage degree was evaluated by 8-OHdG level (B) and comet assay (C). ***p < 0.001 vs. control cells that did no subjected to any treatments; #p < 0.05, ##p < 0.01 and ###p < 0.001 vs. cells treated with CoNPs alone.
