Figure 1  Loss of Nrf2 enhanced cell death after scratch. (a) Cultured astrocytes scratched or not were observed under microscope (×100). There was more cell death in group KO TBI. (b) CCK-8 analysis revealed lower OD value in scratched astrocytes (P < 0.01). Group KO TBI showed significant lower OD value than group WT TBI (P < 0.01). (*P < 0.01, compared with sham counterpart; # P < 0.01, compared with WT TBI).
