Decontamination of ambient RNA in single-cell RNA-seq with DecontX

Open access

Published version of a preprint

Abstract

Droplet-based microfluidic devices have become widely used to perform single-cell RNA sequencing (scRNA-seq). However, ambient RNA present in the cell suspension can be aberrantly counted along with a cell’s native mRNA and result in cross-contamination of transcripts between different cell populations. DecontX is a novel Bayesian method to estimate and remove contamination in individual cells. DecontX accurately predicts contamination levels in a mouse-human mixture dataset and removes aberrant expression of marker genes in PBMC datasets. We also compare the contamination levels between four different scRNA-seq protocols. Overall, DecontX can be incorporated into scRNA-seq workflows to improve downstream analyses.

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

  • DecontX can be applied when empty droplet counts are not available but its results are potentially heavily dependent on the accuracy of the clustering provided.

    “This allows DecontX to be applied when empty droplet counts are not available but also means that the results are potentially heavily dependent on the accuracy of the clustering provided.”
  • DecontX relies on accurate clustering of the data to estimate and remove the background without the need for gene counts from empty droplets.

    “Finally, DecontX [23] relies on accurate clustering of the data to estimate and remove the background without the need for gene counts from empty droplets.”
  • Removing ambient RNA as an initial quality-control step improves downstream analyses for many tissues.

    “one should consider removing ambient RNA as an initial analysis step in quality control to improve downstream analyses for many tissues21–23.”

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.
