This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

In this study, researchers observed that loose anagen hair syndrome is an autosomal dominant disorder characterized by abnormal hair follicle structure and premature keratinization, possibly due to signaling and desmosomal component disturbances.

This study used integrated single-cell chromatin and transcriptomic analyses in developing mouse skin to uncover gene networks involved in skin lineage specification and identified Mef2c+ upper fibroblasts as potential precursors to certain muscle-like structures, with cross-species findings in human skin.

This report describes a child and his father with hereditary hypotrichosis simplex, an uncommon isolated form of hair loss, with no other ectodermal or systemic abnormalities noted.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

This article discusses the anatomical structure and physiological functions of the skin without reporting new research findings.

Understanding hair follicle structure and techniques improves hair restoration outcomes.

This review covers the structure, development, cycle, and molecular regulation of hair follicles but does not report new results, aiming to offer insights for addressing hair follicle-related diseases.

This paper reviews different types of hair shaft dysplasias and does not report any new clinical findings.

Metabolic disorders can cause hair structure defects and growth issues, but amino acid levels in hair remain normal.

This review discusses the physiology of hair follicles, their disorders, and the principles behind developing treatments, reporting no new results.

This review examines the potential of K18 as a diagnostic and prognostic marker in epithelial-derived tumors, highlighting its specific expression in tumor tissues and interaction with proteins involved in tumor progression, without reporting new clinical findings.

This review covers hair anatomy, common hair diseases, diagnostic approaches, management, and hair care, but reports no new clinical findings; the authors highlight the importance of proper hair care knowledge.

Keratin 17 is important for hair and nail structure and affects pachyonychia congenita symptoms.

This study found that the absence of Sostdc1 in mice alters mammary gland and hair follicle development, particularly by increasing vibrissae numbers and causing unusual nipple-like structures.

Monilethrix involves multiple genes affecting hair structure, including DSG4 mutations.

This study mapped gene expression in different skin structures of dogs, finding similarities to humans that support using dogs as models for human skin diseases.

This study diagnosed a group of six girls with various ectodermal abnormalities, identifying cranio-skeletal malformations consistent with focal dermal hypoplasia (Goltz syndrome), and found heterozygous mutations in the PORCN gene in two children.

This article reviews the composition and structure of mammalian hard keratins, focusing on the filamentous and nonfilamentous protein content, and reports no new experimental results.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

This review explores recent insights into the diverse cell populations involved in skin development, homeostasis, wound healing, and cancer progression but reports no new results.

In this study, researchers discussed how specific protein interactions in reptile skin allow for the development of protective structures like scales and scutes, which facilitated reptiles' adaptation to terrestrial environments.

In this study, researchers propose that different vertebrate skin appendages, such as hair, feathers, and scales, evolved in parallel from a shared ancestral cell structure associated with teeth, dating back approximately 420 million years ago.

Trichoscopy is a useful non-invasive method for diagnosing different hair loss conditions.

This review discusses the strategies and progress in developing bioengineered organ replacement therapies but reports no new clinical results, highlighting the potential for future regenerative solutions.

This study found that zebrafish and sticklebacks, despite differences in their tooth regeneration structures, share a similar genetic program during tooth regeneration, suggesting a conserved "successional dental epithelium" in vertebrates.

This review discusses various environmental and chemical factors that contribute to hair shaft disorders, such as fractures, and highlights the potential roles of cysteine and glutamine in hair health, but reports no new results.
