    Abstract:
    Our previous studies identified a sub-population of cholinergic neurons which express nestin in the rostral part of the basal forebrain (BF) in normal adult rats. In the present study, the postnatal developmental patterns of nestin, choline acetyl transferase (ChAT) and parvalbumin (PV) positive neurons were explored by means of immunohistochemistry combined with immunofluorescence double label methods. Compared with early onset of ChAT expression (from P1) and delayed onset of PV expression (from P16), nestin positive activity was detected in the BF from P9 and co-expressed by parts of the ChAT positive neurons within the same region during the whole postnatal development process. However, ChAT and PV were not coexpressed by the neurons within the medial septum-diagonal band of Broca (MS-DBB) of BF. These results might imply a composite of separate development patterns displayed by different subpopulations of cholinergic neurons (nestin positive cholinergic neurons and nestin negative cholinergic neurons) within this region. Moreover, the topographic distribution of nestin, ChAT and PV positive neurons also showed different characteristics. In summary, our present study revealed a remarkable timing and topographic difference on the postnatal development of the nestin expression within the MS-DBB of BF compared with ChAT and PV expression. It is further suggested that nestin is re-expressed by cholinergic neurons in the BF after differentiation but not persisted from neuronal precursor cells.
