The development of sympathetic neurons and chromaffin cells is differentially controlled at distinct stages by various extrinsic and intrinsic signals. Here we use conditional deletion ofDicer1in neural crest cells and noradrenergic neuroblasts to identify stage specific functions in sympathoadrenal lineages. Conditional Dicer1 knockout in neural crest cells ofDicer1Wnt1Cremice results in a rapid reduction in the size of developing sympathetic ganglia and adrenal medulla. In contrast,Dicer1elimination in noradrenergic neuroblasts ofDicer1DbhiCreanimals affects sympathetic neuron survival starting at late embryonic stages and chromaffin cells persist at least until postnatal week 1. A differential function ofDicer1signaling for the development of embryonic noradrenergic and cholinergic sympathetic neurons is demonstrated by the selective increase in the expression of Tlx3 and the cholinergic marker genesVAChTandChATat E16.5. The number ofDbh,ThandTrkAexpressing noradrenergic neurons is strongly decreased inDicer1-deficient sympathetic ganglia at birth, whereas Tlx3+/ Ret+cholinergic neurons cells are spared from cell death. The postnatal death of chromaffin cells is preceded by the loss ofAscl1, mir-375andPnmtand an increase in the markersRetandNF-M, which suggests thatDicer1is required for the maintenance of chromaffin cell differentiation and survival. Taken together, these findings demonstrate distinct stage and lineage specific functions ofDicer1signaling in differentiation and survival of sympathetic neurons and adrenal chromaffin cells.
