Abstract

Summary Sweat glands are abundant glands of our body and essential for thermoregulation. Like mammary glands, they originate from epidermal progenitors. However, they display few signs of cellular turnover, and whether they have stem cells and tissue regenerative capacity remain largely unexplored. Here we address these issues. Using lineage-tracing, we identify multipotent progenitors in sweat duct that transition to unipotency after developing the sweat gland. In characterizing four adult stem cell populations of glandular skin, we show that they display distinct regenerative capabilities and remain unipotent when healing epidermal, myoepithelial-specific and luminal-specific injuries. We devise purification schemes, isolate and transcriptionally profile progenitors. Exploiting molecular differences between sweat and mammary glands, we show that only some progenitors regain multipotency to produce de novo ductal and glandular structures, but that these can retain their identity even within certain foreign microenvironments. Our findings provide new concepts about glandular stem cells and sweat gland biology.

  • SwGs are maintained by stem and progenitor cells within the ducts and coiled glands.

    “SwGs are maintained by stem and progenitor cells within the ducts and coiled glands.[ 2 ]”

    From Sweat Gland Organoids Originating from Reprogrammed Epidermal Keratinocytes Functionally Recapitulated Damaged Skin (2021) · cites this paper as [2]

    The Discussion section “Four Populations of Stem Cells in Adult Pawskin” reports homeostatic turnover in sweat ducts and identifies progenitors in the coiled glands. It also says the glands show little, if any, turnover during normal homeostasis; glandular progenitors proliferated in response to targeted injury. Thus, the source does not establish that progenitors in both compartments actively maintain sweat glands under normal conditions. (LLM, conf=0.84)

  • For large wounds, tissue damage often causes an overall reduction in local stem cells, and progenitor cells within residual SwGs show limited regenerative capacities and respond inefficiently to tissue damage cues.

    “For large wounds, tissue damage often causes an overall reduction in local stem cells, and progenitor cells within residual SwGs show limited regenerative capacities and respond inefficiently to tissue damage cues.[ 2 ]”

    From Sweat Gland Organoids Originating from Reprogrammed Epidermal Keratinocytes Functionally Recapitulated Damaged Skin (2021) · cites this paper as [2]

    The Results section, “Adult Sweat Duct But Not Gland Progenitors Contribute to Epidermal Wound Repair” (page not provided), reports that sweat glands remained quiescent during epidermal wound healing, supporting a limited response in that setting. But the paper does not report that large wounds generally reduce local stem-cell numbers; its Results on localized gland damage instead describe robust proliferation of surviving gland cells. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • SwGs are derived from an epidermal bud of CK5-expressing progenitors, sharing the same origin as epidermal keratinocytes.

    “SwGs are derived from an epidermal bud of CK5‐expressing progenitors,[ 2 , 6 ] sharing the same origin as epidermal keratinocytes that can be readily maintained and propagated in vitro.[ 7 ]”

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.
