In this study, researchers found no hypertrophy in axillary sweat glands of hyperhidrotic patients, with eccrine gland clear cells being the primary site of fluid transport and no evidence of apoeccrine glands.

A 90-year-old woman's hand lesion was a rare, aggressive skin cancer treated successfully with surgery.

The document outlines criteria to identify and differentiate neoplasms based on follicular characteristics.

This case report documents only the second known instance of congenital lymphadenoma, expanding the diagnostic possibilities for cutaneous lymphoepithelial tumors in children.

This study found that mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

This case report describes a trichoblastoma in a 58-year-old man's leg, which was successfully excised without recurrence observed after 9 months.

This article reviews historical reports of skin changes, such as pseudoacanthosis nigricans, associated with cholesterol-lowering drugs like triparanol and nicotinic acid, but presents no new clinical findings.

This article reviews the distinctive features of cutaneous lymphadenoma, a variant of trichoblastoma, and its differential diagnosis, but it presents no new empirical results.

This study found that trichohyalin is expressed in cancerous tongue epithelial cells, while plectin-1 expression may indicate malignancy.

This study demonstrated that bioluminescence imaging of NG2+ cells in transgenic rats allows in vivo monitoring of hair follicle cycles to study hair growth and follicle regeneration.

This article reviews how anatomical differences in skin arise and persist, and suggests the underlying molecular positional code is more complex than apparent, but reports no new research findings.

This study discusses incidental findings of syringomas and syringomatous proliferations in areas of scalp alopecia, suggesting they may be secondary to reactive changes from subclinical alopecia.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

This review discusses environmental reprogramming and the plasticity of epithelial cells, emphasizing their potential for new cell therapy approaches; it reports no new experimental results.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

This chapter describes procedures for isolating and purifying murine epithelial progenitors and assessing their ex vivo propagation capacity, but presents no new experimental results.

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 reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.

This study found that Wnt signaling in the hair follicle is crucial for coordinating the behavior of epithelial and melanocyte stem cells, which drives hair regeneration and melanocyte differentiation in mice.

This article provides contact information for Bruce A. Morgan and features no new research findings.

This review examines current knowledge on human epithelial hair follicle stem cells, their markers, and outlines challenges in translating findings from murine studies to human research, but does not report new experimental results.

This review discusses the roles of interferon-γ and PPAR-γ-mediated signalling in scarring alopecia, suggesting these pathways as potential therapeutic targets, but it reports no new empirical results.

This study found that RANK-RANKL signaling regulates hair renewal and epidermal homeostasis in mice, revealing its role in initiating hair growth cycles and maintaining skin cell activity.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

This study found that Runx1 in hair follicle stem cells modulates lipid metabolism, impacting membrane organization and enhancing signal transduction for cell proliferation in both normal and cancer epithelial cells.

This study identified a specific subpopulation of hair follicle stem cells in mice and humans that are essential for long-term hair regeneration, highlighting the potential for regenerative therapy.

This study found that stabilized beta-catenin is crucial for activating stem cell transition from quiescence to proliferation in hair follicles by influencing gene expression within the stem cell niche.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

In a porcine model, this study observed that using an External Tissue Expansion Device increased epidermis thickness, cell proliferation, and vessel density at fat graft recipient sites.

In this study, a bioengineered construct using a biodegradable polycaprolactone mat cocultured with human keratinocyte and rabbit dermal fibroblast cells demonstrated potential as a tissue-engineered skin substitute, showing good cell adhesion and growth.
