Abstract

Computational single-cell RNA-seq (scRNA-seq) methods have been successfully applied to experiments representing a single condition, technology, or species to discover and define cellular phenotypes. However, identifying subpopulations of cells that are present across multiple data sets remains challenging. Here, we introduce an analytical strategy for integrating scRNA-seq data sets based on common sources of variation, enabling the identification of shared populations across data sets and downstream comparative analysis. We apply this approach, implemented in our R toolkit Seurat (http://satijalab.org/seurat/), to align scRNA-seq data sets of peripheral blood mononuclear cells under resting and stimulated conditions, hematopoietic progenitors sequenced using two profiling technologies, and pancreatic cell 'atlases' generated from human and mouse islets. In each case, we learn distinct or transitional cell states jointly across data sets, while boosting statistical power through integrated analysis. Our approach facilitates general comparisons of scRNA-seq data sets, potentially deepening our understanding of how distinct cell states respond to perturbation, disease, and evolution.

  • Five methods commonly in use for low-MOI single-cell CRISPR screen association testing are Seurat-Wilcox, MIMOSCA, t-test, MAST, and KS test.

    “identified five methods commonly in use: the default Seurat [19] FindMarkers() function based on the Wilcoxon test (Seurat-Wilcox), MIMOSCA [1], a t-test on the library-size-normalized expressions [10], MAST [20], and a Kolmogorov-Smirnov (KS) test on the library-size-normalized expressions [21]”

    From Robust differential expression testing for single-cell CRISPR screens at low multiplicity of infection (2024) · cites this paper as [19]

    The Online Methods section, under “Integrated Analysis Across Datasets” (page unavailable), reports using a Wilcoxon rank-sum test for differential-expression testing in Seurat. It does not identify FindMarkers() or establish that Wilcoxon is that function’s default. The citation [19] is attached to the Seurat method, not to the other four methods in the citing sentence. (LLM, conf=0.82)

  • Batch effects were corrected using FindIntegrationAnchor() and IntegrateData() in the reciprocal PCA approach of the Seurat workflow.

    “Batch effects were corrected with the FindIntegrationAnchor() and the IntegrateData() function in the reciprocal PCA approach of the Seurat workflow.”

    From TBX3 is dynamically expressed in pancreatic organogenesis and fine-tunes regeneration (2023) · cites this paper as [77]

    The Results section (‘Overview of Seurat alignment workflow’; page unavailable) supports the general point that Seurat integrates datasets affected by batch differences. It describes a CCA-based alignment workflow, however, not reciprocal PCA, and the retrieved passages do not identify FindIntegrationAnchor() or IntegrateData() as its functions. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Tumor KCs broadly recapitulated the normal basal, cycling, and differentiating subpopulations, with several shared marker genes across normal skin and cSCC.

    “Canonical correlation analysis (Butler et al., 2018) demonstrated that tumor KCs broadly recapitulated the normal (basal, cycling, and differentiating) subpopulations, with several shared marker genes across normal skin and cSCC”
  • The hdWGCNA R package extends the data structures and functionality of the Seurat package.

    “the hdWGCNA R package extends the data structures and functionality of the widely used Seurat package,5,6,7”
  • hdWGCNA was developed as an R package extending Seurat and has an extensive documentation website demonstrating its use on new datasets.

    “To maximize usability among the genomics community, the hdWGCNA R package extends the data structures and functionality of the widely used Seurat package,5,6,7 and we developed an extensive documentation website for hdWGCNA demonstrating its use on new datasets.”

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.
