This proof-of-concept study reported that a new, ultra-fast, one-step immunohistochemistry method improved the interpretation of Mohs surgery slides, particularly for poorly differentiated tumors.

This study found that solid basal cell epitheliomas and the outer root sheath of human hair follicles display nearly identical cytokeratin profiles, suggesting a potential origin connection.

This study found that keratin immunohistochemistry suggests neoplastic cells in eccrine and apocrine poromas are closely related to dermal sweat duct cells, but cannot differentiate these poromas based solely on keratin patterns.

This study demonstrates a varied distribution of keratins in the epidermis of the Malayan pangolin, suggesting evolutionary adaptations related to their distinctive scales.

This study developed a method to convert fibroblasts into sweat gland-like cells, suggesting potential for regenerating damaged skin and restoring sweat gland function.

This study found cutaneous keratinic amyloid deposition in dogs and identified cytokeratin 5 as an amyloid precursor protein, revealing new insights into the etiology of cutaneous amyloidosis.

This case report describes a rare aggressive variant of squamous cell carcinoma on the scalp of a non-immunosuppressed older male, highlighting its high biological risk for metastasis and poor outcomes.

This case report describes a rare instance of trichogerminoma with unusually numerous mitotic figures and a higher Ki67 proliferative rate, distinguishing it from previously documented cases.

In this study, the immunohistochemical and lectin binding profiles of basal cell carcinoma closely resembled those of the outer root sheath of vellus hair follicles, suggesting a potential histochemical relationship.

This review discusses the paradoxical effects of valproic acid on hair, noting that it can both cause alopecia and stimulate hair growth, but reports no new experimental findings.

This study found that seed oil of Caragana korshinskii demonstrated high antifungal efficacy against Trichophyton mentagrophytes in an in vivo guinea pig model of dermatophytosis.

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 article discusses the complex biological functions and social significance of hair follicles and reports no new research findings, emphasizing their role in health, disease, and a substantial beauty industry.

This study found that SesZen-Bio TM, a proprietary extract from Sesbania grandiflora leaves, increased proliferation of hair cells and hair shaft length in vitro and ex vivo, potentially due to activation of the Wnt/β-catenin signaling and stem cell differentiation pathways.

This study reports a unique case of coinheritance of BRCA2 and CYLD pathogenic variants in a man with metastatic malignant cylindroma, suggesting that recognizing such genetic profiles in rare conditions can provide new treatment options, including the potential use of therapies targeting BRCA deficiency.

This study found that hyaluronic acid increased the size of hair follicle germ-like aggregates and the number of proliferative cells but did not maintain specific markers during the process.

This study highlights a paradox where valproic acid, known for causing hair loss, may also promote hair growth when applied topically.

This article discusses the paradoxical effects of valproic acid on hair, reporting both drug-induced hair loss and the potential for hair growth when used topically, but presents no original research findings.

This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

This review discusses the dynamic, niche-driven regulation of stem cell states in tissue homeostasis and regeneration, focusing on epithelial stem cells in the mammalian skin, intestine, and lung, without providing new experimental results.

This study found that the transcription factor p63 is crucial for horizontal basal cell differentiation in the olfactory epithelium, suggesting a p63-dependent mechanism activates reserve stem cells after injury.

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

This study found that prolactin is a key regulator of keratin expression in human hair follicles, enhancing specific keratin types and influencing epithelial stem cell-associated keratins.

This study identified a novel G207E STING mutation associated with severe inflammatory symptoms and suggested that common polymorphisms in TMEM173 and IFIH1 may modify the phenotype in affected individuals.

This study reported the successful isolation of epithelial stem cells from mouse embryonic skin using a simple culture method, with the cells showing the potential to differentiate into multiple cell types.

This review addresses the role of skin-resident adult stem/progenitor cells in skin homeostasis, disease, and cancer development, and reports no new research results.

This study found that electrospun short fibrous sponges effectively mimic the 3D extracellular matrix, promoting tissue regeneration, angiogenesis, and wound healing in diabetic rats better than 2D fiber membranes.

This study reports that transplantation of an ESCs-collagen-chitin biomimetic membrane leads to successful in situ skin regeneration, including hair follicle cell proliferation and formation of dermatoglyphs, in nude mice with full-thickness skin defects.

This study found that conditional knockout of N-WASP in keratinocytes of mice led to skin barrier defects, increased immune cell infiltration, and hyperproliferation of keratinocytes, indicating its crucial role in skin homeostasis.
