This review highlights the diverse roles of melanocytes in pigmentation, immunity, and hearing among other functions, their involvement in disorders, and their emerging potential in regenerative medicine, including applications in disease modeling and therapy development using advanced technologies.

This study found that CD34- melanocyte stem cells regenerated pigmentation more efficiently, while CD34+ cells showed potential for neuron myelination, suggesting different therapeutic applications for each population.

This study suggests that melanoma tumor cells exhibit intrinsic plasticity, challenging the applicability of the cancer stem cell model to this malignancy.

This review discusses the impact of melatonin and its metabolites on skin aging, summarizing how they may serve as "aging neutralizers" through their anti-oxidative and anti-inflammatory properties, but reports no new clinical results.

This review highlights the possibility of safely altering hair color through innovative cosmetics by targeting key biological processes in hair follicles, using insights from mammalian pigmentation studies and drug-induced hair color changes as potential pathways.

This study examined aging hair follicle stem cells in mice and found that inflammation reduction in dermal white adipose tissue can stimulate regenerative behavior, highlighting its role in hair follicle aging.

This review examines the genetic factors influencing coat color in horses and donkeys, highlighting key genes like MC1R, TYR, MITF, ASIP, and KIT, and discusses implications for selective breeding and the relationship between coat color and specific equine diseases.

In this study, researchers identified key genes such as EDNRB2, GPNMB, TRPM1, TYR, and DCT that regulate melanin deposition in the breast muscles of black-boned chickens, contributing to their unique pigmentation during embryonic development.

Genetic studies on hair traits can improve understanding of health and disease.

This review outlines evidence-based strategies for diagnosing pediatric hypopigmented disorders and emphasizes distinguishing vitiligo from self-limiting conditions through a systematic clinical approach; no new results are reported.

This review discusses forensic DNA phenotyping and its potential applications, particularly for human identification in Latin American populations, but notes challenges due to genetic diversity and reports no new results.

This paper discusses forensic DNA phenotyping, emphasizing its ability to infer visible traits from biological samples without reference samples, but notes ethical and legal concerns related to its use.

This study found that while genetic variants contribute minimally to predicting hair greying in a Polish population, age remains the primary predictor, underscoring the complexity of hair greying as a genetic trait.

This study identified genomic regions and genes associated with wool, live weight, body condition, and reproduction traits in Uruguayan Merino sheep, highlighting potential genetic factors influencing these characteristics.

This study examined the Spanish Merino breed's wool quality, identifying 74 genetic variants linked to key wool traits like fiber diameter and staple length, which could help restore the breed's potential for producing high-quality wool.

This study investigated how keratinocytes in the skin respond to different iron levels and found they play a significant role in regulating iron homeostasis by storing iron, affecting epidermal differentiation, and influencing inflammation-related gene expression in mice.

This study applied a machine learning-based genomic analysis to identify genetic markers associated with wool traits in Central Anatolian Merino sheep, successfully highlighting loci relevant to fiber diameter, staple length, and greasy fleece yield, which could inform breeding programs to enhance wool quality and yield.

In this review, researchers explored how various cell types and molecular mechanisms contribute to wound-induced hair follicle neogenesis, highlighting its potential as a therapeutic approach for regenerating hair follicles and minimizing scar formation after injury.

This review discusses the role of Ysc84/SH3yl1 proteins in linking actin regulation to membrane morphology changes but reports no new experimental results.

This study concluded that dilated cardiomyopathy in Ctsl-deficient mice is mainly due to the lack of cathepsin L in cardiomyocytes, with additional heart stress from the fur defect.

In this study, two unrelated Honduran patients with Sjögren-Larsson syndrome had the same genetic mutation but displayed different disease severities, suggesting that factors beyond the ALDH3A2 mutation influence clinical outcome.

This study concludes that dietary L-serine supplementation shows promise as a long-term therapy for hereditary sensory and autonomic neuropathy type 1, reducing neurotoxic 1-deoxysphingolipid levels and improving symptoms in severe cases.

This study demonstrated that de novo designed bifunctional proteins can target and degrade BCL-xL, leading to cell apoptosis, suggesting a new approach to targeted protein degradation therapy.

This study identified five mutations in the gene LSS in individuals with unexplained hypotrichosis simplex, highlighting a potential role of mislocalized LSS proteins in disrupting hair follicle biology.

This study identified a novel SCF mRNA splice variant in white merino sheep skin, which may play a role in hair follicle melanogenesis.

This study identifies mutations in the SRD5A3 gene as a cause of a new type of congenital disorder of glycosylation, impacting mental, ophthalmologic, and cerebellar functions.

This research found that deleting the SLC3A2 gene in hair follicle stem cells disrupts their maintenance and proper differentiation, leading to hair follicle growth defects and altered skin regeneration through a YAP/Taz-dependent pathway.
