表征人类胚胎发生过程中细胞状态的进展可以为儿科疾病的起源提供见解。我们研究了神经嵴和中胚层来源的谱系分化成肾上腺,肾脏,内皮细胞和造血组织之间的人类发育的怀孕后6周和14周的转录状态。我们的研究结果揭示了过渡连接中间中胚层和器官原基,造血系统和内皮亚型的祖细胞。出乎意料的是,通过使用单细胞转录组学和谱系追踪的组合,我们发现,肾上腺内的交感神经细胞在该阶段是直接来自神经相关的雪旺细胞前体类似于当地的嗜铬细胞,而大多数肾上腺外的交感神经细胞来自迁移的神经嵴。在人类中,这个过程持续几个星期的发展过程中,在大的肾上腺内神经节样结构,这也可能作为水库的起源细胞在神经母细胞瘤。
Characterization of the progression of cellular states during human embryogenesis can provide insights into the origin of pediatric diseases. We examined the transcriptional states of neural crest- and mesoderm-derived lineages differentiating into adrenal glands, kidneys, endothelium, and hematopoietic tissue between post-conception weeks 6 and 14 of human development. Our results reveal transitions connecting intermediate mesoderm and progenitors of organ primordia, the hematopoietic system, and endothelial subtypes. Unexpectedly, by using a combination of single cell transcriptomics and lineage tracing, we found that intra-adrenal sympathoblasts at that stage are directly derived from the nerve-associated Schwann cell precursors similarly to local chromaffin cells, whereas the majority of extra-adrenal sympathoblasts arise from the migratory neural crest. In humans, this process persists during several weeks of development within the large intra-adrenal ganglia-like structures, which may also serve as reservoirs of originating cells in neuroblastoma.
