交感神经元和嗜铬细胞的发育在不同阶段受到各种外在和内在信号的差异控制。在这里,我们使用神经嵴细胞和去甲肾上腺素能神经母细胞中 Dicer1 的条件删除来识别交感肾上腺谱系中的阶段特异性功能。 Dicer1Wnt1Cremice 神经嵴细胞中的条件性 Dicer1 敲除会导致发育中的交感神经节和肾上腺髓质的大小迅速减小。相比之下,Dicer1Dbhi动物的去甲肾上腺素能神经母细胞中Dicer1的消除会影响从胚胎晚期开始的交感神经元存活,并且嗜铬细胞至少持续到出生后第1周。Dicer1信号传导对胚胎去甲肾上腺素能和胆碱能交感神经元发育的差异功能通过Tlx3和胆碱能标记物表达的选择性增加来证明基因VAChTandChaATat E16.5。在Dicer1缺陷的交感神经节中,表达去甲肾上腺素能神经元的Dbh、ThandTrkA数量在出生时急剧减少,而Tlx3+/Ret+胆碱能神经元细胞则免于细胞死亡。嗜铬细胞出生后死亡之前会出现 Ascl1、mir-375 和 Pnm 的丢失以及标记物 Ret 和 NF-M 的增加,这表明 Dicer1 是维持嗜铬细胞分化和存活所必需的。总而言之,这些发现证明了 Dicer1 信号传导在交感神经元和肾上腺嗜铬细胞的分化和存活中的不同阶段和谱系特异性功能。
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.
