Immunohistochemical staining of caspase III. Weak reddish-brown immunoreactivity was demonstrated in neural tissues near the third ventricle of sham-operated normal control rats, whereas strong reactivities were evident in the cortex, hippocampuses, striata and neural tissues close to lateral ventricles and third ventricles of ischemic rats with and without NGF administration or neural stem cell transplant. A: reddish brown coloration of caspase III immunoreactivity along the ventricular lining of cells of ischemic rat having undergone neural stem cell transplant for four weeks, B: caspase III+ cells took the glial morphology. Scale bar: 75 μm.
