This study observed that unpigmented keratinocytes saturate quickly with foreign substance uptake compared to pigmented melanocytes, where melanin significantly enhances binding.

Vitiligo causes white skin patches and is linked to autoimmune issues.

This review examines current understanding of hair graying and suggests it may be caused by depletion of melanocyte stem cells due to genotoxic stress or dysfunctional melanocytes from oxidative stress.

This review discusses the types, causes, and treatments for skin pigmentation disorders, examining clinically tested options including 25 plants, four marine species, and 17 medications.

This study found that PDGF-BB affects human melanocytes differently depending on their differentiation stage, stimulating melanoblast proliferation but inhibiting melanocyte proliferation while promoting their differentiation.

In this study, researchers explored the heterogeneity of pigment cells in the human scalp anagen hair follicle bulb and discovered unexpected subpopulations of melanocytes, including immature SOX10-negative cells, highlighting potential non-melanogenic roles or transitional migratory functions that require further investigation.

This study observed unexpected heterogeneity among pigment cells in human scalp hair follicles, identifying immature melanocyte populations outside traditional pigment production zones, raising questions about their potential roles beyond melanin synthesis.

This case report describes a rare instance of reversible melasma-like hyperpigmentation linked to vitamin B12 deficiency due to pernicious anemia, and explores possible mechanisms for this association.

This review discusses how hair follicle light sensitivity is linked to mesenchymal remodeling and suggests that this connection influences photoepilation outcomes and optimal treatment strategies, reporting no new clinical results.

In this report, two cases of melanocytic matricoma, a rare benign hair follicle lesion that mimics melanoma and basal cell carcinoma, were described and successfully treated with complete surgical excision. Histological analysis was crucial for differentiation from similar malignant lesions.

This review discusses Becker's Melanosis and Hypertrichosis in young males, summarizing cases observed in Melbourne with clinical and histological analyses, but reports no new clinical findings.

This review discusses the clinical manifestations and genetic basis of pigmentary mosaicism, highlighting its varied phenotypic expressions, but reports no new clinical results.

In this study, 7-10-year-old Polish children showed a significant increase in skin pigmentation levels, with girls exhibiting this change more prominently than boys, suggesting an early sign of puberty.

The researchers observed that vitiligo-affected skin shows a selective depletion of NTRK2+ melanocyte subpopulations with progenitor features, which may contribute to poor treatment responses.

This study explored the immune environment of the hair follicle's bulge region and suggested that its unique signaling may prevent melanoma formation by lacking necessary proinflammatory signals for full oncogenic transformation, indicating potential strategies for melanoma prevention by replicating this immune-privileged environment.

This letter to the editor shares a case study of lentiginous melanoma that appears clinically malignant but histopathologically benign, involving the BRAFV600R mutation.

This study reported that in men with androgenic alopecia, a distinct subclinical hyperpigmentation pattern was observed in the scalp, associated with baldness severity and possibly linked to local melanin production by pilosebaceous units.

This review suggests that dermatological cosmetic procedures can be safely performed on dark-complexioned skin with appropriate treatment adjustments, highlighting the need for careful consideration to prevent adverse effects.

This study found that non-cutaneous melanocytes in mice are less sensitive to Kit signaling compared to cutaneous melanocytes, showing dependence on ET3 and HGF signaling.

In this study, chitosan membranes enhanced melanocyte proliferation and survival by supporting both cell-cell and cell-substrate interactions, unlike polyvinyl alcohol membranes which only facilitated cell-cell interactions.

This study found that extracts from Hom Thong banana peels, rich in phenolic compounds, may inhibit melanin production in human and mouse melanoma cells, showing potential as anti-melanogenic agents comparable to standard treatments like arbutin and kojic acid.

This study found that certain proteins linked to immune suppression and melanogenesis are associated with repigmentation in vitiligo patients undergoing standard treatment, suggesting these proteins and their pathways play roles distinct from merely reversing skin lesions.

This research discusses a zebrafish model showing that nicastrin deficiency leads to tyrosinase-dependent depigmentation and melanophore cell death, suggesting implications for studying skin depigmentation disorders.

This study observed that injecting mice with α-MSH resulted in black hair regrowth in shaved and plucked areas, suggesting a potential link to the agent darkening hair in animals with a specific pituitary tumor.

The researchers reported that mouse keratinocyte-specific deletion of laminin γ1 led to delayed coat pigmentation due to impaired melanocyte migration and differentiation, linked to altered laminin composition in the basement membrane.

This article reports a rare combination of rapid-onset halo nevi, nonsegmental vitiligo, and premature scalp hair graying.

This study found that patients with the MITF p.E318K variant are more likely to develop multiple primary melanomas and dysplastic nevi with uncommon dermoscopic patterns compared to non-carriers.

The girl's regrown brown hair had less of certain pigments than her original black hair.
