Abstract

The development of in vitro and ex vivo models to mimic human illness is important not only for scientific understanding and investigating therapeutic approaches but also to mitigate animal testing and bridge the inter-species translational gap. While in vitro models can facilitate high-throughput and cost-efficient evaluation of novel therapeutics, more complex ex vivo systems can better predict both desirable and adverse in vivo effects. Here we describe an ex vivo cultured human skin explant model in which we have characterized pathological tissue integrity, barrier function and metabolic stability over time. Our findings suggest that human skin can be successfully cultured for pharmacodynamic use up to and beyond 9 days without any adverse physiological consequence.

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

  • Metabolism is far less in previously frozen skin kept on saline solution for 24 hours compared to in vivo.

    “Metabolism is known to be far less in previously frozen skin kept on saline solution for 24 hours compared to in vivo (Neil et al., 2020).”

    From Human skin absorption of three phthalates (2024) · cites this paper as Neil et al., 2020

    The Conclusions (page unavailable) report a discrepancy in metabolic biomarkers between the cultured human skin explant model and skin in vivo. They do not say metabolism is far less in previously frozen skin, or assess skin kept in saline for 24 hours. The Methods describe tissue kept chilled before culture in modified Cornification medium, not previously frozen tissue held in saline. (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.
