Abstract

The hair follicle bulge possesses putative epithelial stem cells. Characterization of these cells has been hampered by the inability to target bulge cells genetically. Here, we use a Keratin1-15 (Krt1-15, also known as K15) promoter to target mouse bulge cells with an inducible Cre recombinase construct or with the gene encoding enhanced green fluorescent protein (EGFP), which allow for lineage analysis and for isolation of the cells. We show that bulge cells in adult mice generate all epithelial cell types within the intact follicle and hair during normal hair follicle cycling. After isolation, adult Krt1-15-EGFP-positive cells reconstituted all components of the cutaneous epithelium and had a higher proliferative potential than Krt1-15-EGFP-negative cells. Genetic profiling of hair follicle stem cells revealed several known and unknown receptors and signaling pathways important for maintaining the stem cell phenotype. Ultimately, these findings provide potential targets for the treatment of hair loss and other disorders of skin and hair.

  • KRT15 and SOX9 were expressed broadly in the organoid HF outer root sheath as well as the bulge-like region.

    “We found that the HF bulge and epithelial stem cells markers, KRT15 and SOX9, were expressed broadly in the organoid HF outer root sheath as well as the bulge-like region (Morris et al., 2004; Nowak et al., 2008; Figure 6B–B″″).”

  • Quiescent stem cells that regenerate hair follicles reside in the bulge.

    “Quiescent stem cells that are responsible for regenerating the hair follicles lie within the bulge of the hair follicles21,31,32”

  • Initiation of a new anagen cycle depends upon activation of a small number of quiescent stem cells that reside in the bulge.

    “Initiation of a new anagen cycle depends upon activation of a small number of quiescent stem cells that reside in the bulge, a niche at the follicle base15–19.”

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.
