Abstract

Single-cell RNA sequencing can reveal the transcriptional state of cells, yet provides little insight into the upstream regulatory landscape associated with open or accessible chromatin regions. Joint profiling of accessible chromatin and RNA within the same cells would permit direct matching of transcriptional regulation to its outputs. Here, we describe droplet-based single-nucleus chromatin accessibility and mRNA expression sequencing (SNARE-seq), a method that can link a cell's transcriptome with its accessible chromatin for sequencing at scale. Specifically, accessible sites are captured by Tn5 transposase in permeabilized nuclei to permit, within many droplets in parallel, DNA barcode tagging together with the mRNA molecules from the same cells. To demonstrate the utility of SNARE-seq, we generated joint profiles of 5,081 and 10,309 cells from neonatal and adult mouse cerebral cortices, respectively. We reconstructed the transcriptome and epigenetic landscapes of major and rare cell types, uncovered lineage-specific accessible sites, especially for low-abundance cells, and connected the dynamics of promoter accessibility with transcription level during neurogenesis.

  • Milo may also be useful for single-cell assays beyond scRNA-seq, including multi-omic assays.

    “Milo may also be applicable to single-cell assays other than scRNA-seq, including multi-omic assays [35–39].”
  • SNARE-seq applied droplet microfluidics to measure more than 10,000 mRNA transcripts and chromatin accessibility in the same cell.

    “As an alternative, single-nucleus chromatin accessibility and mRNA expression sequencing (SNARE-seq) used droplet-based microfluidics to co-profile over 10,000 mRNA transcripts with chromatin accessibility from the same single cell57.”
  • Paired experimental methods are easier computationally because modalities can be tethered to a single cell or spot, but sequencing capacity of each modality decreases overall sample size.

    “By contrast, paired experimental methods (10x Multiome, SHARE-seq60, DBiT-seq123, SNARE-seq57, CITE-seq68 and others) are easier to work with computationally as different modalities can be tethered to a single cell or a single spot; however, the sequencing capacity of each modality causes the overall sample size to decrease.”
  • Single-cell multiomics allows uncovering mechanisms of gene regulation across different omics layers but lacks spatial information, which is crucial to understanding cellular function in tissue.

    “Single-cell multiomics allows uncovering of the mechanisms of gene regulation across different omics layers6–9 but lacks spatial information, which is crucial to understanding cellular function in tissue.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
