This review discusses changes in keratin structure or gene expression that result in various skin disorders and reports no new clinical findings.

This article reviews the current literature on rosacea, focusing on the new subtype classification system and the main theories of its pathogenesis, but reports no new clinical results.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

This review summarizes the roles of matricellular proteins in skin stem cell niches, highlighting their contribution to stem cell fate, self-renewal, and potential implications for wound healing and aging.

This research reports that the polyG fragment within the Hoxc13 protein alters its gene regulatory functions, which could have influenced mammalian hair evolution by affecting pathways related to hair follicle development.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This review discusses the expanding understanding of TRPV3's role in pain and skin pathology, while highlighting the need for further pharmacological research to fully resolve its functions.

This review explores the complex interactions between hair follicle stem cells and surrounding structures that are essential for understanding hair regeneration, reporting no new experimental results.

This genome-wide association study identified 20 genetic signals at 15 risk loci related to severe acne, revealing new insights into its genetic predisposition, particularly affecting skin structure and maintenance.

This study found that α-MSH administration before skin wounding in adult mice reduced inflammation and scar area, suggesting a potential pathway to more regenerative healing.

This study mapped the safety profile of EGFR-TKIs by analyzing FDA adverse event reports, highlighting unexpected reactions like intestinal obstruction and hypokalaemia with gefitinib and erlotinib.

This study describes a mouse model for Marie Unna Hereditary Hypotrichosis, identifying mutations in the hairless gene that result in sparse or absent hair and cyst-like hair follicles.

This study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

This review article highlights recent advances in microneedle technology for wound healing and tissue regeneration, discussing various cargo types, structural designs, and fabrication methods, and suggesting guidelines for designing microneedle systems tailored to specific applications.

This chapter defines skin integrity as a blend of intact structural elements and adaptable functional capacity, highlighting its importance in maintaining skin health across various conditions but reports no new research findings.

This study found that the systemic wrinkled skin phenotype in Xiang pigs involves gene expression changes and genetic variations associated with oxidative stress and extracellular matrix components, resembling features seen in Shar-Pei dogs.

This review discusses the effects of vacuum massage on skin structures and concludes that there is insufficient evidence for its efficacy in treating burn scars, suggesting more research is needed on its potential benefits and mechanisms.

This study found that deleting FoxN1 in specific thymic epithelial cells disrupted the 3D thymic structure and led to age-dependent formation of 2D epithelial cysts, highlighting FoxN1's critical role in thymic morphogenesis.

In this study, the researchers reported the detailed anatomical structure of horse skin, including the composition and organization of the epidermis, dermis, and associated glands and follicles.

This study suggests that using sebaceous glands from rat tail skin samples may effectively capture hair follicle stem cells, potentially aiding skin regenerative medicine when available tissue is limited.

This study found that by using an automated system to analyze skin histology, 108 structural features were significantly affected by age, and it identified four new aging biomarkers and notable sex-based differences in skin aging.

In this study, researchers observed that mice with the naked gene showed frequent absence of hair cuticle and cortical cells during follicle growth, with abnormal keratin deposition also noted.

This study reported that albino Wistar rats exposed to chemical hair straighteners showed significant hair fiber damage and scalp skin deterioration, which worsened with repeated and prolonged application, highlighting the cytotoxic potential of these products and potential systemic risks.

In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.

This study revealed key cellular dynamics and interactions during early embryonic mouse skin development, highlighting complex transitions from precursor states to diverse multilayered structures.
