A human cell atlas of fetal chromatin accessibility


ABSTRACT: We devised an improved assay for single cell profiling of chromatin accessibility with three-level combinatorial indexing (sci-ATAC-seq3). We applied this method to 53 fetal tissue samples representing 15 organs, altogether profiling approximately one million single cells. We leveraged cell types defined by gene expression in the same organs to annotate these data, and built a catalog of hundreds-of-thousands of candidate gene regulatory elements exhibiting cell type-specific accessibility. Our analyses focus on the properties of lineage-specific transcription factors, organ-specific specializations of broadly distributed cell types, and cell type-specific enrichments of complex trait heritability. Additional data formats are available at atlas.brotmanbaty.org.
