The changed distribution of Foxj1 in injured brain cortex by immunohistochemical staining. a, b We could observe the staining of Foxj1 in the sham-operated brain, and the level was relatively lower. c, d The same staining was found in the equal contralateral hemisphere of the injured brain; however, the level was low as the sham brain. e, f We could see that the immunostaining of Foxj1 deposited strongly adjacent to the lesion site, in addition the level was significantly higher compared with the sham and the contralateral hemisphere of the brain after TBI. g Quantitative analysis of Foxj1 positive cells/mm² between contralateral and ipsilateral brains 3 days after injury. Foxj1 was significantly increased in the ipsilateral brain at 3 days after TBI. Asterisk indicated significant difference at P < 0.05 compared with contralateral brain. Error bars SEM. Scale bars: left columns (a, c, e), 50 μm; right columns (b, d, f), 10 μm
