Abstract
On post-soman day 9, the cytokine treatment had no effect on the proliferation of neural progenitors in the SVZ and SGZ, as assessed by BrdU immunochemistry. However, this treatment seemed to promote the migration of neural precursor cells from the proliferative areas towards damaged brain regions. Indeed, in the CA1 hippocampal layer of soman-poisoned mice, on post-soman day 34, the cytokine treatment increased the number of healthy pyramidal neurons stained by hemalun-eosin dye. The cytokine treatment also augmented the number of BrdU-labeled cells in the CA1 hippocampal layer and amygdala. Interestingly, the administration of cytokines resulted in the differentiation of BrdU-positive cells into new neurons in the CA1 hippocampal layer, whereas astrocytic differentiation was preferentially observed in the amygdala.
