    Abstract:
    Nestin(+) neurons have been shown to express choline acetyltransferase (ChAT) in the medial septum-diagonal band of Broca in adult rats. This study explored the projection of nestin(+) neurons to the olfactory bulb and the time course of nestin(+) neurons in the medial septum-diagonal band of Broca in adult rats during injury recovery after olfactory nerve transection. This study observed that all nestin(+) neurons were double-labeled with ChAT in the medial septum-diagonal band of Broca. Approximately 53.6% of nestin(+) neurons were projected to the olfactory bulb and co-labeled with fast blue. A large number of nestin(+) neurons were not present in each region of the medial septum-diagonal band of Broca. Nestin(+) neurons in the medial septum and vertical limb of the diagonal band of Broca showed obvious compensatory function. The number of nestin(+) neurons decreased to a minimum later than nestin(-)/ChAT(+) neurons in the medial septum-diagonal band of Broca. The results suggest that nestin(+) cholinergic neurons may have a closer connection to olfactory bulb neurons. Nestin(+) cholinergic neurons may have a stronger tolerance to injury than Nestin(-)/ChAT(+) neurons. The difference between nestin(+) and nestin(-)/ChAT(+) neurons during the recovery process requires further investigations.
