Abstract

Single-cell RNA sequencing (RNA-seq) is a powerful tool to reveal cellular heterogeneity, discover new cell types and characterize tumor microevolution. However, losses in cDNA synthesis and bias in cDNA amplification lead to severe quantitative errors. We show that molecular labels--random sequences that label individual molecules--can nearly eliminate amplification noise, and that microfluidic sample preparation and optimized reagents produce a fivefold improvement in mRNA capture efficiency.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Venus protein expression correlates mostly with RNA findings, except weak acinar expression around E18.5 which appears underestimated in scRNA sequencing data.

    “These patterns correlate mostly with the RNA findings, except the weak but robust acinar expression around E18.5 which appears underestimated in scRNA sequencing data potentially attributed to technical limitations for weakly expressed genes [50–54].”
  • By counting molecules rather than the number of amplified sequencing reads, one can account for biases related to amplification and obtain more accurate estimates of gene expression levels.

    “The rationale is that by counting molecules rather than the number of amplified sequencing reads, one can account for biases related to amplification, and obtain more accurate estimates of gene expression levels71220.”
  • These observations underscore the importance of using UMIs in single cell gene expression studies.

    “These observations concur with previous studies1220 as they underscore the importance of using UMIs in single cell gene expression studies.”
  • Both endogenous and ERCC spike-in control CV patterns approximately followed an over-dispersed Poisson distribution.

    “Both endogenous and ERCC spike-in control CV patterns approximately followed an over-dispersed Poisson distribution (Supplementary Fig. S11), which is consistent with previous studies1120.”
  • The UMI protocol maintains strand information.

    “Because the UMI protocol maintains strand information, we required that reads map to a gene in the correct orientation (featureCounts flag -s 1).”

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.
