This study found that the HoxC gene cluster plays a critical role in the development of ectodermal organs, including hair and nails, with mammalian-specific enhancers increasing transcription levels during development.

This review discusses various nonfollicular scalp conditions causing secondary scarring or permanent alopecia and highlights the importance of specific diagnoses and treatments but reports no new results.

In this case report, the authors suggest an association between prolonged finasteride use and anterior subcapsular cataracts, as observed in a 43-year-old man, marking the first reported instance.

This study found that the progression of fetal skin development, marked by key features like the appearance of hair follicles and eccrine sweat glands, can help determine fetal age and predict congenital skin diseases.

This source reports findings from a case study detailing hair loss in two female patients, published in the JDDG: Journal der Deutschen Dermatologischen Gesellschaft, emphasizing that specific diagnostic outcomes or treatment results are not included in the summary.

This case report highlights a 17-year-old female with Kartagener's syndrome and ectodermal anomalies, such as alopecia and dental issues, suggesting a possible novel syndromic variant, with genetic testing recommended to distinguish it from a dual diagnosis.

This article discusses hair and nail research contributions in dermatology but reports no new clinical findings.

This study discusses the effects of collagen hydrolysates and the dipeptide Pro-Hyp on gene expression related to hair and epidermis development in mouse skin and reports no new clinical results.

This mini-review discusses human hair follicle development and summarizes genetic disorders linked to abnormalities in hair follicle morphogenesis, structure, or regeneration, but reports no new experimental results.

This review discusses recent advances in molecular genetics and their impact on the accuracy and understanding of diagnosing inherited skin diseases but reports no new results.

In this case report, a 45-year-old Jordanian woman was diagnosed with Clouston syndrome, an autosomal-dominant disorder characterized by alopecia and nail dystrophy due to a mutation in the GJB6 gene, though she lacked the typical palmoplantar keratoderma.

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

This study found that the Wnt inhibitor Dkk4 may play a role in regulating hair follicle development through a feedback loop with canonical Wnt signaling pathways.

This study identified a missense variant in the EDA gene of a male cat, which likely caused hypohidrotic ectodermal dysplasia, characterized by hair and teeth abnormalities; this represents the first report of such a genetic condition in cats.

This study found that loss-of-function mutations in the HOXC13 gene cause autosomal-recessive pure hair and nail ectodermal dysplasia, emphasizing its role in hair and nail development.

In this study on Drosophila wings, researchers identified 435 genes with significant expression changes during wing hair morphogenesis, and found new phenotypes for 9 genes through functional validation.

This article reviews Cronkhite-Canada syndrome as a distinct condition from Peutz-Jeghers syndrome and familial polyposis, with cases showing gastrointestinal polyposis, skin, hair, nail abnormalities, and hypoproteinemia.

This review examines the roles of Hedgehog and Gli proteins in mouse embryonic mammary development and suggests that Gli3-repressor-mediated off-state of Hedgehog signaling determines mammary fate over hair follicle fate.

This study found that combining a human acellular amniotic membrane with iPSC-derived epithelial stem cells effectively repaired skin defects and promoted hair follicle formation in nude mice.

This review discusses recent advances in developmental tissue engineering for regenerating ectodermal appendages like teeth and glands, emphasizing biomaterial selection and cell culture strategies, but reports no new experimental results.

This study identified a gene expression signature in mouse embryonic dermal fibroblasts that depends on Wnt/β-catenin activity, potentially influencing dermal fibroblast identity and function.

This study indicates that transient Msx2 expression is critical for wound-induced hair follicle neogenesis, with distinct phases in the healing process essential for epidermal competence and hair regeneration.

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

Children's hair loss can be caused by many factors, including autoimmune diseases, emotional stress, genetics, and infections, with treatment and prognosis varying.

This review summarizes major growth factors that promote hair follicle growth, but it reports no new experimental findings.

This article reviews common scalp and hair disorders in children and adolescents and outlines diagnostic approaches, but reports no new clinical findings.

This report describes a unique case of Schöpf–Schulz–Passarge syndrome in a Taiwanese man linked to a previously unreported homozygous WNT 10A mutation, underscoring its role in ectodermal dysplasia.
