This review discusses the role of epidermal differentiation complex genes and epigenetic mechanisms in skin development and certain diseases, emphasizing their potential for improving drug development and delivery systems but provides no new experimental results.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

This review discusses the role of cholesterol homeostasis in hair follicle biology and its potential connections to various hair disorders, but it reports no new findings.

This study found that the absence of sebaceous glands may be an early factor in the development of keratosis pilaris, leading to hair shaft and skin barrier abnormalities, independent of filaggrin mutations.

This study found that male pattern hair loss may be associated with differences in serum levels of androstenedione, cortisol, 17 beta-estradiol, and luteinizing hormone, compared to controls.

Local skin glucocorticoid production is crucial for healthy skin, and its disruption can lead to skin diseases.

This study found that while a nanostructured lipid carrier improved drug delivery in conventional skin models, excess sebaceous content hindered its effectiveness in targeting hair follicles.

This study reports a new association of follicular mucinosis occurring in a patient with Sézary syndrome.

This study found that sulfur mustard affects hair follicles and sebaceous glands in the skin by causing cellular damage, inflammation, and disrupting wound healing processes in hairless mice.

In this study, melatonin administration enhanced various cellular and structural features of the scrotal skin in Soay rams, including increased thickness, cell count, and gland activity.

This review discusses the clinical presentations of alopecia areata, introduces guidelines for treatment studies, and explores potential changes in cutaneous innervation, but reports no new clinical results.

This review highlights the occurrence of yellow dots, a trichoscopic finding, in several scalp conditions beyond alopecia areata and reports no new clinical results.

This study found that young C57BL/6 and BALB/c mice exhibit distinct regenerative patterns during ear wound healing, with greater wound closure but less regeneration in middle-aged C57BL/6 mice.

This study found that transplanted cultured epithelium from adult rat sole keratinocytes can respond to growth signals from dermal papillae and form follicular structures, especially with dermis support.

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 TRH modulates specific keratins in human scalp tissue, suggesting its potential influence on hair growth and the need for further exploration of neuroendocrine controls in keratin expression.

This study found that COX-2 expression in normal rat skin is linked to the hair cycle, with varying levels observed in different skin structures during anagen, catagen, and telogen phases.

This study demonstrates that Tp63-expressing epithelial stem cells from non-skin tissues can respond to skin morphogenetic signals and contribute to the formation of hair follicles, sebaceous glands, and epidermis.

This article discusses the importance of oral and maxillofacial surgeons understanding the pathogenesis and treatment of acne vulgaris, but it presents no new research findings.

The side gland of Suncus murinus is a good model for studying human sebaceous glands.

This study found that mutations in the hairless gene disrupt normal hair follicle development by impairing Wnt/β-catenin signaling, affecting hair keratinocyte differentiation in both mice and humans.

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.

This study identified a high-risk allele in the PLCD1 gene associated with hereditary trichilemmal cyst formation, proposing a monoallelic two-hit mechanism as the underlying genetic pathogenesis.

This study reports the first documentation of mural, mucinotic, isthmus folliculitis alopecia in Norwegian puffin dogs, noting that ciclosporin treatment led to remission while other treatments were less effective.

This study found that Epstein pearls and Mongolian spots are the most common skin lesions in newborns in India, influenced by interracial, environmental, and hormonal factors.

Flamena, a liposomal mix, helps skin heal better after a chemical burn.

This review summarizes the link between acne pathogenesis and skin barrier dysfunction, noting that more severe acne correlates with greater skin barrier damage, but reports no new clinical results.

In this study, isotretinoin treatment significantly increased p53 expression in the skin of acne vulgaris patients, correlating with reduced acne severity and suggesting mechanisms for sebum suppression and side effects.

The document explains how hair follicles develop, their structure, and how they grow.

Understanding skin structure and development helps diagnose and treat skin disorders.
