FGF2 Attenuates Neural Cell Death via Suppressing Autophagy after Rat Mild Traumatic Brain Injury

Figure 6

PI-positive cells in the ipsilateral cortex 6 h post-TBI in different groups. (a) Representative microphotographs showed the colocalization of DAPI (blue) with PI-positive (red) cells in the ipsilateral cortex and CA1 region 6 h post-TBI. Scale bar = 100 μm. (b) The quantification of the PI-positive cells as the necrosis index as a percent of the total DAPI+ cells. The bars represent the mean ± SD. . versus sham and ^# versus TBI + vehicle.
