The chromatin landscape underlying the specification of human cell types is of fundamental interest. We generated human cell atlases of chromatin accessibility and gene expression in fetal tissues. For chromatin accessibility, we devised a three-level combinatorial indexing assay and applied it to 53 samples representing 15 organs, profiling ~800,000 single cells. We leveraged cell types defined by gene expression to annotate these data, and catalog hundreds-of-thousands of candidate regulatory elements exhibiting cell type-specific chromatin accessibility. We investigate the properties of lineage-specific transcription factors (e.g. POU2F1 in neurons), organ-specific specializations of broadly distributed cell types (e.g. blood, endothelial), and cell type-specific enrichments of complex trait heritability. These data represent a rich resource for the exploration of in vivo human gene regulation in diverse tissues and cell types. We report a human cell atlas of fetal chromatin accessibility spanning 15 organs.
