Abstract

Cellular senescence is a stress-response mechanism implicated in various physiological processes, diseases, and aging. Current detection approaches have partially addressed the issue of senescent cell identification in clinical specimens. Effective methodologies enabling precise isolation or live tracking of senescent cells are still lacking. In-depth analysis of truly senescent cells is, therefore, an extremely challenging task. We report (1) the synthesis and validation of a fluorophore-conjugated, Sudan Black-B analog (GLF16), suitable for in vivo and in vitro analysis of senescence by fluorescence microscopy and flow cytometry and (2) the development and application of a GLF16-carrying micelle vector facilitating GLF16 uptake by living senescent cells in vivo and in vitro. The compound and the applied methodology render isolation of senescent cells an easy, rapid, and precise process. Straightforward nanocarrier-mediated GLF16 delivery in live senescent cells comprises a unique tool for characterization of senescence at an unprecedented depth.

  • Both glial cells capable of proliferation and postmitotic neurons can express markers of cellular senescence in aging, obesity, traumatic injury, and neurodegeneration.

    “Both proliferation-competent glial cells (which constitute approximately 50% of brain cells) and postmitotic neurons can be positive for markers of cellular senescence in aging, obesity, traumatic injury, and neurodegeneration31,45–49, among other conditions.”

    From Guidelines for minimal information on cellular senescence experimentation in vivo (2024) · cites this paper as [48]

    The paper’s sections on senescence model systems and live-cell delivery describe cell lines, airway organoids, tumors, and lung tissue, not senescence markers in glial cells or neurons. Searches for glia, neurons, brain, obesity, traumatic injury, and neurodegeneration found no passage addressing the attributed claim; an Alzheimer’s-related title appears only in the References (page unavailable). (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Senescence markers have been demonstrated in post-mitotic cells.

    “while the presence of senescence markers has been proven even in post-mitotic cells”

    From Guidelines for minimal information on cellular senescence experimentation in vivo (2024) · cites this paper as [48]

    The Discussion describes senescence markers and detection in cell cultures and murine models, but the passages found do not identify the cells as post-mitotic. Searches for post-mitotic cells and for nondividing cell types did not find a passage establishing the claimed point. (LLM, conf=0.70)

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.
