单细胞基因组学研究已经解码了几种人类产前器官的免疫细胞组成,但在理解发育中的免疫系统作为跨组织的分布式网络方面受到限制。我们分析了9个产前组织,结合单细胞RNA测序,抗原受体测序和空间转录组学来重建发育中的人类免疫系统。这揭示了骨髓和淋巴细胞亚群的免疫效应功能的晚期获得以及外周组织接种之前单核细胞和T细胞的成熟。此外,我们发现了主要造血器官以外的全系统血液和免疫细胞发育,表征了人类产前B1细胞,并揭示了非常规T细胞的起源。我们的图谱提供了宝贵的数据资源和生物学见解,将促进细胞工程,再生医学和疾病的理解。
Single-cell genomics studies have decoded the immune-cell composition of several human prenatal organs but were limited in understanding the developing immune system as a distributed network across tissues. We profiled nine prenatal tissues combining single-cell RNA sequencing, antigen-receptor sequencing, and spatial transcriptomics to reconstruct the developing human immune system. This revealed the late acquisition of immune effector functions by myeloid and lymphoid cell subsets and the maturation of monocytes and T cells prior to peripheral tissue seeding. Moreover, we uncovered system-wide blood and immune cell development beyond primary hematopoietic organs, characterized human prenatal B1 cells, and shed light on the origin of unconventional T cells. Our atlas provides both valuable data resources and biological insights that will facilitate cell engineering, regenerative medicine, and disease understanding.
