Abstract

High-throughput single-cell transcriptomics offers an unbiased approach for understanding the extent, basis and function of gene expression variation between seemingly identical cells. Here we sequence single-cell RNA-seq libraries prepared from over 1,700 primary mouse bone-marrow-derived dendritic cells spanning several experimental conditions. We find substantial variation between identically stimulated dendritic cells, in both the fraction of cells detectably expressing a given messenger RNA and the transcript's level within expressing cells. Distinct gene modules are characterized by different temporal heterogeneity profiles. In particular, a 'core' module of antiviral genes is expressed very early by a few 'precocious' cells in response to uniform stimulation with a pathogenic component, but is later activated in all cells. By stimulating cells individually in sealed microfluidic chambers, analysing dendritic cells from knockout mice, and modulating secretion and extracellular signalling, we show that this response is coordinated by interferon-mediated paracrine signalling from these precocious cells. Notably, preventing cell-to-cell communication also substantially reduces variability between cells in the expression of an early-induced 'peaked' inflammatory module, suggesting that paracrine signalling additionally represses part of the inflammatory program. Our study highlights the importance of cell-to-cell communication in controlling cellular heterogeneity and reveals general strategies that multicellular populations can use to establish complex dynamic responses.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Even cells of the same type can exhibit substantial heterogeneity, reflecting finer sub-types, regulated functional variation, or inherent stochasticity.

    “even cells of the same ‘type’ can exhibit substantial heterogeneity, reflecting finer sub-types, regulated functional variation, or inherent stochasticity1–6”
  • Correlating the expression profiles of genes or proteins opens the way to elucidating the regulatory mechanisms that control them.

    “In analogy to simple observational approaches for inferring gene regulation, correlating the expression profiles of genes or proteins opens the way to elucidating the regulatory mechanisms that control them2,3,41,169,170.”
  • Several studies have analyzed the covariation structure between transcripts or proteins across single cells to infer regulatory relations.

    “Leveraging this insight, several studies have analyzed the covariation structure between transcripts or proteins across single cells to infer regulatory relations1–3,41,135,137,168–172.”
  • Prior work found that single-cell cellular and genomic features can be measured by methods like RNA-sequencing and remain well-preserved after microfluidic exposure.

    “Previous studies have found that cellular and genomic properties of single cells can be measured using techniques such as RNA-sequencing and are well- preserved following exposure to microfluidic environments28.”

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.
