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.

In this study, researchers developed a method to differentiate human iPSCs into cells that can generate all lineages of hair follicles, potentially aiding treatments for hair loss and skin disorders.

This case report introduces a novel instance of long-term cutaneous neoplastic degeneration following artificial hair implantation, a previously unreported complication in such procedures.

This study found that previously undescribed WNT10A mutations are a prominent cause of various forms of ectodermal dysplasia, including OODD and Schöpf-Schulz-Passarge syndrome, with gender-specific phenotypic effects noted.

This study found that maintaining a low level of Wnt/β-catenin activity is crucial for mammary gland development, as excessive activity inhibits branching and promotes characteristics of hair follicles instead, highlighting its role in skin appendage identity decisions.

This study found that Prss53-mutated rabbits exhibited curved hair and skeletal dyskinesia, suggesting a link between Prss53 loss and these traits, potentially involving disrupted calcium metabolism.

In this review, the researchers detailed how the p63 transcription factor influences epithelial stem cell activities such as self-renewal, differentiation, and proliferation, highlighting the role of TAp63 and ΔNp63 isoforms in both normal tissue development and cancer pathogenesis.

This review discusses the role of keratins in epithelial cell stress protection and cancer, highlighting their potential as multifunctional regulators and diagnostic markers, without presenting new research findings.

This study found that transgenic mice expressing human keratin K8 in the epidermis showed increased progression of skin lesions toward malignancy, suggesting a role for K8 in the development of invasive skin cancer.

This review examines the role of P-cadherin in skin and hair biology, emphasizing its importance in human hair growth, cycling, and pigmentation, and reports no new research findings.

Lichen Planus is a less common condition affecting skin and mucous membranes, with various types and associated risk factors, challenging to diagnose, significantly impacts life quality, and may have a risk of cancerous changes in oral lesions.

This study found that Plakophilin 1 regulates innate immune responses in keratinocytes by controlling RNA helicase activity, balancing inflammation during epidermal immune challenges.

This review discusses the incidence, prevalence, and risk factors for epidermal cancer and premalignant epidermal neoplasia, and it reports no new clinical findings.

This review evaluates existing research on Keratin 15 to assess its validity as a marker for epidermal stem cells, reporting no new results.

This study found that HPV16 oncogene expression in multipotent epithelial stem cells led to abnormal mobilization, altering their quiescence without affecting other stem cell markers, suggesting a distinct stem cell compartment.

This study found that macrophages near hair follicles contribute to the activation of skin epithelial stem cells in mice, suggesting a novel role for macrophages in regulating hair growth.

This review discusses the role of mechanical forces in skin homeostasis and disease development, including their impact on conditions like keloids, androgenetic alopecia, and acral melanoma, and reports no clinical results; the authors propose modifying these forces as a potential therapeutic strategy.

This study found that HPV-150 and HPV-151 are rare genotypes with a preference for skin tissue, detected in some cases of skin lesions with generally low viral loads.

This review discusses the relationship between ectodermal alterations and immunodeficiencies, particularly the roles of hyper-IgE syndrome, ectodermal dysplasia, and FOXN1 gene mutations, but it presents no new research findings.

This study found that lineage-restricted loss of p63 in murine thymic epithelial cells resulted in severe thymic hypoplasia and absence of hair follicles, indicating p63's critical role in thymic and hair follicle development.

This article provides a detailed analysis of immunosuppressive medications in transplant patients and discusses the increased risk of skin cancer, but it reports no new experimental results.

In this study, researchers found that the expression of vimentin, desmin, and laminin in rat skin contributes to cell structure and tissue integrity, with varying reactions across different cell types.

This study found that the combination of docetaxel, cisplatin, and 5-fluorouracil is active and feasible for treating squamous cell carcinoma of the head and neck, with dose level I recommended for further testing.

This entry contains only a placeholder abstract with no research findings described or summarized.

This book reviews actinic keratosis from a multidisciplinary perspective, covering topics such as epidemiology, immunology, and clinical manifestations, but reports no new research results.

This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

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 index of Harper's Textbook of Pediatric Dermatology, Fourth Edition, provides no clinical results or new findings.

This article reviews the complex signaling pathways between epithelial and mesenchymal cells crucial for hair follicle morphogenesis, highlighting the Wnt pathway's role as a master regulator without reporting new experimental findings.
