Abstract

Recent generation of patient-specific induced pluripotent stem cells (PS-iPSCs) provides significant advantages for cell- and gene-based therapy. Establishment of iPSC-based therapy for skin diseases requires efficient methodology for differentiating iPSCs into both keratinocytes and fibroblasts, the major cellular components of the skin, as well as the reconstruction of skin structures using these iPSC-derived skin components. We previously reported generation of keratinocytes from human iPSCs for use in the treatment of recessive dystrophic epidermolysis bullosa (RDEB) caused by mutations in the COL7A1 gene. Here, we developed a protocol for differentiating iPSCs into dermal fibroblasts, which also produce type VII collagen and therefore also have the potential to treat RDEB. Moreover, we generated in vitro 3D skin equivalents composed exclusively human iPSC-derived keratinocytes and fibroblasts for disease models and regenerative therapies for skin diseases, first demonstrating that iPSCs can provide the basis for modeling a human organ derived entirely from two different types of iPSC-derived cells.

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

  • Human skin equivalents have notable drawbacks, such as a lack of crucial skin tissue structures (e.g., hair follicles and sebaceous glands) and limited culture durations (e.g., 2-3 weeks).

    “However, human skin equivalents have notable drawbacks, such as a lack of crucial skin tissue structures (e.g., hair follicles and sebaceous glands) and limited culture durations (e.g., 2–3 weeks)”

    From Generation and characterization of hair-bearing skin organoids from human pluripotent stem cells (2022) · cites this paper as [19]

    The Discussion describes the paper’s in vitro 3D skin equivalent as lacking skin appendages, supporting the structural drawback. The Methods report harvesting the equivalent after approximately 18–20 days of preparation, but do not say that its culture duration is limited to 2–3 weeks. (LLM, conf=0.86)

  • Conventional primary cell-based HSEs have transitioned to more standardized and reproducible in vitro culture models using immortalized cell lines or hiPSC-derived cells.

    “Furthermore, in response to challenges associated with donor variability, conventional primary cell-based HSEs have transitioned to more standardized and reproducible in vitro culture models. These models utilize either immortalized cell lines [45] or cells derived from hiPSCs [17].”
  • 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.”
  • In vitro skin derivation strategies have focused on generating keratinocytes and fibroblasts from pluripotent stem cells in separate cultures first, then combining the two cell types to form a skin-like bilayer.

    “To date, in vitro skin derivation strategies have focused on generating keratinocytes and fibroblasts from PSCs in separate cultures first, then combining the two types of cells to form a skin-like bilayer (Gledhill et al., 2015; Itoh et al., 2013; Oh et al., 2013; Sun et al., 2014).”

    From Hair Follicle Development in Mouse Pluripotent Stem Cell-Derived Skin Organoids (2018) · cites this paper as Itoh et al., 2013

  • The logic of these approaches is that the individual parts can be combined to generate full-thickness skin.

    “The logic of these approaches is that the individual parts can be combined to generate full-thickness skin (Itoh et al., 2013).”

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.
