Figure 7: Assessment of nuclear translocation of Nrf2 redox-response element in MSCs challenged with LPS. Counterstaining of nuclear DNA was with Hoechst 33342 (blue channel). Nrf2 staining is in green. Nrf2 localized in nuclei appears in turquoise/green color due to interference of “green” and “blue” (indicated with arrows). Experimental conditions were the same as indicated in Figure 2.
