| Outline of Final Research Achievements |
Although exercises enhance functional recovery from the strokes, it is not known about the cellular mechanisms. We made brain infarction by surgical occlusion of the left median cerebral artery. After the strokes, the rats were injected with 5-bromo-2’-deoxyuridine (BrdU) and then given exercise by treadmill and sacrificed 1 week (W), 4W and 8W. The brains were compared between exercised and non-exercised groups by immune-staining using antibodies against BrdU and Sox2 (immature neural marker). Lots of immature cells were moved from the subventricular zone (SVZ) to the peri-infarcted regions. We could not detect significant difference of the moves between the groups. However, BrdU-positive cells were significantly increased in the separated cortex from the infarcted lesions in the exercised group. The numbers of BrdU-positive cells were remarkably decreased by the 8W, suggesting that most of the BrdU-positive cells does not differentiate to matured neuron.
