Abstract

Stem cells exhibit promise in numerous areas of regenerative medicine. Their fate and function are governed by a combination of intrinsic determinants and signals from the local microenvironment, or niche. An understanding of the mechanisms underlying both embryonic and adult stem cell functions has been greatly enhanced by the recent development of several high-throughput technologies: microfabricated platforms, including cellular microarrays, to investigate the combinatorial effects of microenvironmental stimuli and large-scale screens utilizing small molecules and short interfering RNAs to identify crucial genetic and signaling elements. Furthermore, the integration of these systems with other versatile platforms, such as microfluidics and lentiviral microarrays, will continue to enable the detailed elucidation of stem cell processes, and thus, greatly contribute to the development of stem cell based therapies.

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

  • Results from 2D and 3D spheroid culture indicated spheroids were more resistant to 5-fluorouracil, whereas 2D cultures were more resistant to tirapazamine.

    “Their results from 2D and 3D spheroid culture indicated spheroids were more resistant to one anti-cancer drug, 5-fluorouracil, which inhibits proliferation, whereas 2D cultures were more resistant to a different anticancer drug, tirapazamine, which is cytotoxic in hypoxic conditions (111).”

    From Modeling physiological events in 2D vs. 3D cell culture (2017) · cites this paper as [111]

    The Introduction discusses stem-cell culture platforms and small-molecule screens, but does not report a 2D-versus-spheroid drug-response comparison. Searches for spheroids, 5-fluorouracil, and tirapazamine found no passage addressing the claimed resistance results; the indexed passages provide no page numbers. (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.
