Abstract

Normal cells can permanently lose the ability to proliferate when challenged by potentially oncogenic stress, a process termed cellular senescence. Senescence-associated beta-galactosidase (SA-betagal) activity, detectable at pH 6.0, permits the identification of senescent cells in culture and mammalian tissues. Here we describe first a cytochemical protocol suitable for the histochemical detection of individual senescent cells both in culture and tissue biopsies. The second method is based on the alkalinization of lysosomes, followed by the use of 5-dodecanoylaminofluorescein di-beta-D-galactopyranoside (C12FDG), a fluorogenic substrate for betagal activity. The cytochemical method takes about 30 min to execute, and several hours to a day to develop and score. The fluorescence methods take between 4 and 8 h to execute and can be scored in a single day. The cytochemical method is applicable to tissue sections and requires simple reagents and equipment. The fluorescence-based methods have the advantages of being more quantitative and sensitive.

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

  • The FACS method based on SPiDER-β-gal labels all SA-β-gal+ cells.

    “we established a fluorescence-activated cell sorting (FACS) method based on the fluorescent probe SPiDER-β-gal (hereafter, SPiDER; similar to the C12FDG fluorescent probe)25,26, which labels all SA-β-gal+ cells (Extended Data Fig. 1d).”
  • During aging, the cytotoxic activity of immune cells decreases, and the expression of functional molecules associated with cytotoxic activity, such as IFN-γ, granzyme B, and perforin, is reduced.

    “More recent studies have shown that, during aging, the cytotoxic activity of immune cells decreases, and the expression of functional molecules associated with cytotoxic activity, such as interferon gamma (IFN-γ), granzyme B, and perforin, is also reduced [31–34] (Table 1).”

  • SA-βgal is a known marker of senescent cells.

    “senescence-associated beta-galactosidase (SA-βgal), a known marker of senescent cells (Debacq-Chainiaux et al., 2009)”
  • Increased activity of lysosomal β-galactosidase is a primary characteristic of senescent cells, exploited as SA-β-gal.

    “To specifically target senescent cells, we focused on one primary characteristic of senescent cells — the increased activity of lysosomal β-galactosidase, exploited as senescence-associated β-galactosidase (SA-β-gal).18,19”

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.
