Abstract

Adult tissue-specific stem cells are essential for homeostatic tissue maintenance and key to regeneration during injury repair or disease. Many critical stem cell functions rely on the presence of well-timed cues from the microenvironment or niche, which includes a diverse range of components, including neuronal, circulating and extracellular matrix inputs as well as an array of neighboring niche cells directly interacting with the stem cells. However, studies of stem cells and their niche have been challenging due to the complexity of adult stem cell functions, their intrinsic controls and the multiple regulatory niche components. Here, we review recent major advances in our understanding of the complex interplay between stem cells and their niche that were enabled by the tremendous technological leaps in single-cell transcriptome analyses, 3D in vitro cultures and 4D in vivo microscopy of stem cell niches.

  • Culture systems containing epidermal and dermal cells have been used to model human skin outside of the body for research or clinical uses for over 40 years.

    “Culture systems containing epidermal and dermal cells have been used to model human skin outside of the body for research or clinical uses for over 40 years7,8,10; however, growing functional skin appendages in these systems has been persistently difficult.”

    From Hair-bearing human skin generated entirely from pluripotent stem cells (2020) · cites this paper as [8]

    The “Modeling complexity” section (page unavailable) describes cultured epidermal and dermal clusters as a skin model, supporting the general point that these cells have been used in culture. Its example uses mouse cells, however, and our copy does not establish use to model human skin for over 40 years or for clinical purposes. (LLM, conf=0.83)

  • Reconstruction of appendage-bearing skin in cultures and in bioengineered grafts remains an unmet biomedical challenge.

    “Reconstruction of appendage-bearing skin in cultures and in bioengineered grafts remains an unmet biomedical challenge3–9.”

    From Hair-bearing human skin generated entirely from pluripotent stem cells (2020) · cites this paper as [8]

    The Modeling complexity section says flat cultures lack tissue complexity and reports that older mouse skin clusters lost the ability to induce hair follicles, although this could be rescued. It also describes murine skin organoids that make hair and sebaceous glands. These passages support limitations in cultured skin reconstruction, but the paper does not address bioengineered skin grafts or characterize their reconstruction as an unmet challenge. (LLM, conf=0.78)

  • Growing functional skin appendages in culture systems containing epidermal and dermal cells has been persistently difficult.

    “Culture systems containing epidermal and dermal cells have been used to model human skin outside of the body for research or clinical uses for over 40 years7,8,10; however, growing functional skin appendages in these systems has been persistently difficult.”

    From Hair-bearing human skin generated entirely from pluripotent stem cells (2020) · cites this paper as [8]

    In “Modeling complexity: 2D co-cultures and 3D tissue-recapitulating organoids” (page unavailable), the review says 3D epidermal–dermal clusters from old mouse skin lost the ability to induce hair follicles, although that ability could be rescued. This supports a difficulty in a particular culture system, but does not establish that growing functional skin appendages has been persistently difficult across the skin culture systems described in the claim; the review also describes murine organoids capable of making hair and sebaceous glands. (LLM, conf=0.78)

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.
