The molecular characterization of postganglionic sympathetic neurons by RNA sequencing has allowed the full assessment of gene expression in individual cells and classification of neurons into subpopulations defined by their gene expression profile and developmental history. The identification of growth factor receptor subunits specifically expressed by select neuron subpopulations enabled the demonstration of GDNF family ligands and the respective receptor subunits as instrumental in the innervation of certain targets. These are first critical steps in the attempt to characterize the molecular processes leading to the establishment and maintenance of target-specific sympathetic efferent pathways.
