Changes in the expression of NSCs in the brain after IR. (a) IHC shows the expression of Nestin under different types of IR at different times. (b) The AOD values of Nestin(+) at 24 h after 20 Gy IR. (c) The AOD values of Nestin(+) at 24 h after 30 Gy IR. (d) The AOD values of Nestin(+) at 7 days after 20 Gy IR. (e) The AOD values of Nestin(+) at 7 days after 30 Gy IR. *p < 0.05; **p < 0.01; ***p < 0.001.
