Abstract

In vitro differentiation of human intestinal organoids (HIOs) from pluripotent stem cells is an unparalleled system for creating complex, multicellular three-dimensional structures capable of giving rise to tissue analogous to native human tissue. Current methods for generating HIOs rely on growth in an undefined tumour-derived extracellular matrix (ECM), which severely limits the use of organoid technologies for regenerative and translational medicine. Here, we developed a fully defined, synthetic hydrogel based on a four-armed, maleimide-terminated poly(ethylene glycol) macromer that supports robust and highly reproducible in vitro growth and expansion of HIOs, such that three-dimensional structures are never embedded in tumour-derived ECM. We also demonstrate that the hydrogel serves as an injection vehicle that can be delivered into injured intestinal mucosa resulting in HIO engraftment and improved colonic wound repair. Together, these studies show proof-of-concept that HIOs may be used therapeutically to treat intestinal injury.

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

  • Matrigel is mainly composed of laminin, collagen IV, entactin, perlecan, and growth factors, and its composition resembles the basement membrane.

    “Matrigel is mainly comprised of laminin, collagen IV, entactin, perlecan and growth factors, and is similar in composition to the basement membrane62.”

    From Organoids (2022) · cites this paper as [62]

    The passage labeled Abstract (page unavailable) describes Matrigel as a mixture of ECM proteins, proteoglycans, and growth factors. It does not identify laminin, collagen IV, entactin, or perlecan as its main components, or say that its composition resembles the basement membrane. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Other matrices with defined compositions, such as recombinant human collagen, fibrin, or synthetic hydrogels, have been explored as alternatives to Matrigel.

    “Therefore, other matrices with defined compositions64 have been explored as alternative matrices to Matrigel, such as recombinant human collagen62, fibrin65, or synthetic hydrogels3,63.”

    From Organoids (2022) · cites this paper as [62]

  • Spheroids are being used to emulate organs such as the intestine, liver, kidney, brain, and heart to study human development and disease in vitro.

    “These spheroids are being used to emulate organs such as the intestine2, liver3, kidney4, brain5, and heart6 to study human development and disease in vitro.”
  • Organoid viability was reduced at high PEG density and matrix stiffness.

    “Organoid viability was reduced at high PEG density and matrix stiffness;”

    From Towards organoid culture without Matrigel (2021) · cites this paper as [163]

  • When PEG was crosslinked with dithiothreitol to inhibit matrix degradation, organoid viability at seven days was poor as measured by live-dead staining.

    “Intriguingly, when PEG was crosslinked with dithiothreitol to inhibit matrix degradation, organoid viability at seven days was poor as measured by live-dead staining.”

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.
