N-syndecan, a receptor for pleiotrophin, is expressed by nigral dopaminergic neurons. Triple immunolabeling in the substantia nigra pars compacta for TH (A, blue), N-syndecan (B, green) and PTN (C, red) showing co-localization of the three markers in some neurons (solid arrow-heads). The open arrow-head indicates a cell that only contains N-syndecan, the open arrow indicates a cell that contains PTN and TH, and the solid arrows indicate cells immunoreactive for TH that do not contain PTN or N-syndecan. Scale bar: 50 μm.
