Abstract

Stem cells generate the differentiated cell types within many organs throughout the lifespan of an organism and are thus ultimately responsible for the longevity of multicellular organisms.Therefore, senescence of stem cells must be prevented.Bmi1 is required for the maintenance of adult stem cells in some tissues partly because it represses genes that induce cellular senescence and cell death.

  • Many adult stem or progenitor cells do not proliferate indefinitely, whether mouse or human in origin.

    “However, many adult stem or progenitor cells do not proliferate indefinitely, whether mouse or human in origin (Geiger and Van Zant, 2002; Chen, 2004; Park et al., 2004; Villa et al., 2004).”

    From Senescent cells, tumor suppression, and organismal aging: good citizens, bad neighbors (2005) · cites this paper as Park et al., 2004

    The 'Stem cells and senescence' section says mouse hematopoietic stem cells can undergo only a limited number of serial transplants, suggesting they may not be immortal. It does not establish the same limit for human adult stem or progenitor cells, or for many cell types generally; the 'Future directions' section also notes that stem-cell senescence during normal aging is controversial.

  • Polycomb group proteins play a role in regulation of expression from the Ink4a/Arf locus, and Bmi1 is implicated in this process.

    “Several studies suggest a role for polycomb group proteins in the regulation of expression from the Ink4a/Arf locus, and Bmi1, a key component of the polycomb complex, has been widely implicated in this process (37,38).”

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.
