This study reports a case of cystic panfolliculoma, highlighting the role of epithelial-mesenchymal interactions in its pathogenesis and explaining its histological resemblance to trichofolliculoma.

This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

This article argues that lineage labeling with genetic markers is the gold standard for identifying epithelial stem cells, contrary to the view that in vitro methods alone are sufficient.

This study identified genetic variations in the DSG4 gene among sheep, revealing valuable markers for assessing their impact on wool traits.

This study identified two cell surface markers, FAP and CD90, that distinguish between papillary and reticular fibroblasts in human skin, suggesting distinct functions and distribution in dermal layers.

This review discusses various stem cell compartments in adult murine and human epidermis, examining their expressed markers and characterization assays, and reports no new experimental results.

This study found that stimulating dermal papilla cells with specific adipo-osteogenic factors and growth factors helped maintain their viability and restored their hair-forming activity in vitro.

In this study, chick embryo extract enhanced neuronal differentiation and trophic factor expression in rat hair follicle stem cells, suggesting potential improvements for stem cell therapies in neurodegenerative diseases.

This dissertation reports that Lrig1 and Lgr6 mark distinct stem cell populations in mouse hair follicles, playing roles in tissue regeneration and tumor development, with Lgr6 regulating Wnt signaling and restraining epidermal lineage commitment.

This review discusses how epidermal Langerhan's cells and dermal cells may influence keratinocyte environments, potentially aiding in the formation of stem cell niches and cellular variety in the basal layer, without providing novel results.

Human hair follicles can provide stem cells for regenerative medicine.

This study found that differentiated airway epithelial cells can revert into functional stem cells in vivo, suggesting a more general role for this dedifferentiation process in tissue regeneration in higher vertebrates.

This review discusses the distinct roles and surprising developmental flexibility of multiple somatic stem cell types in tissue maintenance and repair, reporting no new results but highlighting emerging questions about their regulation and origins.

This study found that wounding in skin induces significant fibroblast heterogeneity and recruits myeloid cells, which contribute to adipocyte regeneration in mice.

This review discusses the diverse roles and characteristics of epidermal and dermal stem cells in skin regeneration and aging, highlighting their potential applications in regenerative medicine and reports no new clinical results.

This study reports that myoepithelial cells in submucosal glands can act as reserve stem cells, regenerating surface airway epithelium after severe injury through a mechanism involving Sox9 and Wnt signaling.

The gene for Marie Unna hereditary hypotrichosis is located on chromosome 8p21, near the hairless gene.

This study found that CXCL12+ fibroblast subsets in mouse skin play a critical role in recruiting neutrophils and defending against S. aureus infection, with similar fibroblast activity observed in human psoriatic skin.

This study found that dermal fibroblast cultures, especially those with higher alpha-smooth muscle actin expression, can be used to produce skin-derived precursor cells, unlike human hair follicle dermal papilla cultures.

This study found that Krox20 marks a diverse stem cell population in mouse hair follicles, which significantly contributes to the interfollicular epidermis and regulates epidermal homeostasis.

This study found that hair follicle-derived dermal stem cells and bone marrow mesenchymal stem cells have similar growth, differentiation capabilities, and surface marker expressions, suggesting hair follicles could be accessible sources for mesenchymal stem cells.

This article reviews keratosis follicularis squamosa, a keratinizing disorder predominantly found in the Japanese population, but reports no new clinical results.

This study observed that stem cells from the hair follicle dermis share similarities with bone marrow-derived mesenchymal stem cells and have potential to form neural-like cells under specific conditions.

This study found that individuals with early onset extensive androgenetic alopecia have an elevated ratio of DHT to testosterone, but no significant genetic linkage to markers on chromosomes 2 or 5 was detected.

In this study, researchers identified Tenascin-C as a marker for touch dome keratinocytes, which maintain themselves and can develop into Merkel cells following injury, showing they share molecular traits with various epidermal keratinocytes.

The conclusion is that CD90 is not a specific marker for fibroblast subtypes and better methods are needed to identify them.

This study found that in Hutchinson–Gilford progeria syndrome, iPSCs committed to the keratinocyte lineage faster than normal cells, with LEF1 expression reduced and a partial rescue of the phenotype achieved through adenine base editing.

This study found that Ng2+ perivascular cells in mouse skin are a diverse lineage-restricted population primarily recruited from papillary or reticular fibroblast lineages during wound healing, maintaining heterogeneity in both wounded and non-wounded skin.

In this study, researchers found that bulge cells cultured from rat hair follicles demonstrated stem cell characteristics and could differentiate into neural and glial lineages.
