Abstract

We engineered an ultrasensitive reporter of p16 INK4a , a biomarker of cellular senescence. Our reporter detected p16 INK4a -expressing fibroblasts with certain senescent characteristics that appeared shortly after birth in the basement membrane adjacent to epithelial stem cells in the lung. Furthermore, these p16 INK4a+ fibroblasts had enhanced capacity to sense tissue inflammation and respond through their increased secretory capacity to promote epithelial regeneration. In addition, p16 INK4a expression was required in fibroblasts to enhance epithelial regeneration. This study highlights a role for p16 INK4a+ fibroblasts as tissue-resident sentinels in the stem cell niche that monitor barrier integrity and rapidly respond to inflammation to promote tissue regeneration.

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

  • Senescent cells have important physiological roles and their clearance may be detrimental in certain conditions.

    “It should be noted, however, that senescent cells also have important physiological roles and that their clearance may be detrimental in certain conditions3–5.”
  • There are beneficial effects of senescent cells in certain circumstances.

    “Furthermore, there are beneficial effects of senescent cells in certain circumstances, which brings more critical requirements to study the right time and condition for senolytics to overcome the harmful effects.16”
  • Cellular senescence is not a mammalian-specific phenomenon but is widespread across the animal kingdom, including vertebrate and invertebrate organisms.

    “Cellular senescence is not a mammalian-specific phenomenon but is widespread across the animal kingdom, including vertebrate and invertebrate organisms.”

    From Guidelines for minimal information on cellular senescence experimentation in vivo (2024) · cites this paper as [116]

    The Abstract and Discussion describe p16INK4a-expressing cells and senescent characteristics in mice, but do not address whether cellular senescence occurs across the animal kingdom. Searches for vertebrates, invertebrates, and evolutionary conservation found no passage supporting that claim; page numbers are unavailable in our copy. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Senescence in non-mammals impacts many aspects of organismal physiology, from development to regeneration and ageing.

    “Senescence in non-mammals impacts on many aspects of organismal physiology, from development116,122 to regeneration (e.g., salamander limbs117, zebrafish fins118, whole hydra polyps120) and ageing119,123,124.”

    From Guidelines for minimal information on cellular senescence experimentation in vivo (2024) · cites this paper as [116]

    Citation 117 is attached to the example of salamander limb regeneration. The paper’s Abstract and section on epithelial stem cell regeneration describe lung repair in mice, not salamanders or other non-mammals. Searches for salamanders, axolotls, limbs, zebrafish and hydra found no passage addressing that example. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Markers of senescence have been detected in birds, amphibians, fish, and invertebrates.

    “Markers of senescence have been detected in birds (e.g., quail114), amphibians (e.g., axolotls115, xenopus116, and newts117), fish (e.g., zebrafish118 and killifish119), and invertebrates (e.g., hydra120 and Drosophila121).”

    From Guidelines for minimal information on cellular senescence experimentation in vivo (2024) · cites this paper as [116]

    The 'High-sensitivity fluorescent reporter of p16 INK4a in vivo' section (page unavailable) reports senescence markers in mouse lung fibroblasts, not in any of the animal groups named in the claim. Searches for the named species and for senescence markers in non-mammalian animals found no passage addressing those groups. (LLM, conf=0.76)

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.
