This study found that UVB exposure led to visible tanning and distinct DNA methylation changes in pigmentation genes in tan-capable skin but not in non-tan skin, highlighting GNAS as a potentially UVB-responsive gene.

This review suggests that melasma may be a photoaging skin disorder affecting genetically predisposed individuals, which could significantly influence its treatment and prevention strategies.

This study found that the patchwork mutation in mice affects melanocyte survival in hair follicles, leading to a variegated coat pattern without partially pigmented hairs due to a community effect among melanoblasts.

In this study, the researchers optimized a method for culturing melanocyte precursors from hair follicles and found that 1,25-dihydroxyvitamin D3 significantly promotes their differentiation and melanin synthesis.

This study reports that the side population technique can isolate melanocyte stem cells from human hair follicles, potentially allowing them to be used for skin pigmentation repopulation.

This review discusses the causes and diagnostic process for facial hypermelanosis, emphasizing the need to rule out systemic disorders like Addison's disease; it reports no new clinical findings.

This study found that silencing clock genes BMAL1 or PER1 in human hair follicles increased melanin content and melanocyte activity, suggesting these genes influence pigmentation.

This article discusses how the balding scalp's exposure to UV and near-infrared light may accelerate aging, with changes detectable under ultraviolet light; it presents no new clinical findings.

The book discussed in this abstract is a comprehensive guide to hair analysis, detailing the latest methods and applications across various fields such as toxicology and drug monitoring, designed for both newcomers and experts in the field.

This case study highlights Erythromelanosis follicularis faciei et colli as an easily overlooked pigmentary disorder characterized by a distinctive triad requiring precise diagnosis for effective patient counseling and cosmetic management.

This study found that pimecrolimus enhances melanin synthesis and promotes melanocyte migration, possibly by increasing MITF protein expression, which may explain its effectiveness in repigmenting vitiligo.

This study confirms that human CD34+ melanocyte stem cells can be differentiated into melanin-producing cells, suggesting potential for cellular therapy in treating skin degenerative diseases.

In this study, researchers discovered two new signaling pathways that regulate how melanocytes establish pigment patterns in reconstituted hair-bearing skin, offering insights that could inform strategies to prevent hair greying.

This review explores recent findings on the roles of melanocyte and melanocyte stem cells in the hair follicle, highlighting their importance for skin health and potential applications in regenerative medicine, but reports no new clinical results.

This review discusses the genetic and metabolic factors influencing hair pigmentation, as well as conditions leading to hypo- or depigmented hair, and reports no new experimental findings.

This review discusses various aspects of hair color, including its formation and evolutionary variations, based on research presented at the 4th Intercontinental Meeting of Hair Research Societies 2004, without providing new experimental results.

This study suggests that different melanocyte subpopulations in hair follicles have varying patterns of apoptosis and survival during the catagen phase, which may inform models for modulating melanocyte behavior in vivo.

This article discusses melatonin's role in mammalian coat color and its potential in melanoma treatment when used with chemotherapy, but reports no new clinical results.

This study suggests that the structure and function of mouse melanocytes in the epidermis and hair bulb are influenced by genetic factors and local tissue environment, including hormones and growth factors.

This review explored the therapeutic potential of Bhangra (Eclipta alba) for treating premature greying of hair, noting the plant's melanogenic, antioxidant, and revitalizing properties, but highlighted the need for further research to scientifically support its effectiveness.

This study found that combining platelet-rich plasma with 4% hydroquinone was more effective in reducing melasma symptoms than using hydroquinone alone.

This study suggests that holes found in mature hair fibers may be linked to daily hair care actions and the removal of extractable substances.

In this study, researchers examined chicken feather follicle tissues from differently colored chickens and found that the genes SLC45A2 and GPNMB are involved in promoting melanin deposition, which enriches understanding of the genetic mechanisms affecting feather color.

This study found that a novel hydrogel scaffold, cGEL, significantly increased melanin production and melanotic gene expression in human melanocytes compared to other graft materials, suggesting its potential as a superior carrier for skin grafting.

This review examines the differential aging of melanocytes in hair follicles and skin, and reports no new findings; the authors suggest further research is needed to understand these processes.

This review discusses the role of the MC1R gene in human pigmentation and its genetic variants, reporting no new results; the authors highlight its forensic applications for phenotypic prediction.

This study introduced a novel in vitro assay for tracking melanosome transfer between melanocytes and keratinocytes, facilitating the quantification of melanin transfer and supporting the role of filopodia as a conduit.

This case report describes a rare instance of melanocytic matricoma, a benign pigmented papule found in sun-damaged skin of an elderly individual, highlighting its distinct clinical and pathological features.

In this study, researchers found that exosomes derived from Pinctada martensii mucus can effectively inhibit melanin production in melanoma cells and zebrafish without adverse effects, potentially offering a promising therapeutic strategy for treating pigmentary disorders by modulating the NF-κB signaling pathway.

This study describes how feather pigmentation in birds is regulated by melanocyte distribution, differentiation, and patterned agouti expression, contributing to diverse and adaptive color patterns.
