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

Figure 5

Cortical cellular apoptosis in the ipsilateral cortex 48 h post-TBI in different groups. (a) Representative microphotographs showed the colocalization of DAPI (blue) with TUNEL-positive (green) cells in the ipsilateral cortex and CA1 region 48 h post-TBI. Scale bar = 100 μm. (b) The quantification of the TUNEL-positive cells as the apoptosis index as a percent of the total DAPI+ cells. The bars represent the mean ± SD. . versus sham and ^# versus TBI + vehicle.
