Abstract

Single-cell RNA sequencing has become a powerful and essential tool for delineating cellular diversity in normal tissues and alterations in disease states. For certain cell types and conditions, there are difficulties in isolating intact cells for transcriptome profiling due to their fragility, large size, tight interconnections, and other factors. Single-nucleus RNA sequencing (snRNA-seq) is an alternative or complementary approach for cells that are difficult to isolate. In this review, we will provide an overview of the experimental and analysis steps of snRNA-seq to understand the methods and characteristics of general and tissue-specific snRNA-seq data. Knowing the advantages and limitations of snRNA-seq will increase its use and improve the biological interpretation of the data generated using this technique.

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

  • Use of nuclei enables study of postmortem, frozen, or biobank tissue, including neurodegenerative conditions such as Alzheimer's disease.

    “Additionally, the use of nuclei, rather than whole cells, enables the study of samples that were previously difficult to analyze via scRNA-seq, such as postmortem, frozen, or biobank tissue, including those obtained from individuals with neurodegenerative conditions such as Alzheimer’s disease (AD)[12, 16].”

    From Comparative analysis of nuclei isolation methods for brain single-nucleus RNA sequencing (2026) · cites this paper as [12]

    The Experimental Procedures section says archived frozen tissue is a primary target for single-nucleus RNA sequencing, and “Neurons in the brain” describes its use with postmortem human brain tissue. That section also discusses neurodegenerative disease, but the copy does not explicitly establish the claimed use of biobank tissue from individuals with Alzheimer’s disease; Alzheimer’s appears only in a cited study’s title in the References. Page numbers were not available in our copy. (LLM, conf=0.82)

  • snRNA-seq overcomes the need for intact cell dissociation, thereby minimizing dissociation-associated challenges and providing a more physiologically accurate representation of the brain's cellular heterogeneity.

    “snRNA-seq overcomes the need for intact cell dissociation, thereby minimizing dissociation-associated challenges and providing a more physiologically accurate representation of the brain’s cellular heterogeneity[12, 14, 15].”

    From Comparative analysis of nuclei isolation methods for brain single-nucleus RNA sequencing (2026) · cites this paper as [12]

    The Abstract says snRNA-seq avoids enzymatic dissociation of intact cells and can reduce cellular and stress-response biases. The “Neurons in the brain” section says it improves representation of neuronal cell types, but also notes limitations in capturing non-neuronal cells and recommends combining it with scRNA-seq. The source therefore does not establish that snRNA-seq alone gives a more physiologically accurate representation of the brain’s overall cellular heterogeneity. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Conventional cell dissociation protocols often compromise neuronal integrity through mechanical shearing or induce glial activation.

    “For example, conventional cell dissociation protocols often compromise the integrity of neurons through mechanical shearing or induce the activation of glia[6, 8–12].”

    From Comparative analysis of nuclei isolation methods for brain single-nucleus RNA sequencing (2026) · cites this paper as [12]

    The Abstract says enzymatic tissue dissociation may damage neurons, and the Experimental Procedures section describes neurons as fragile and difficult to dissociate. The paper does not attribute neuronal damage to mechanical shearing or say that dissociation induces glial activation. No page numbers were supplied for these passages. (LLM, conf=0.86)

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.
