This study found that tribuloside, a flavonoid from Tribulus terrestris L., enhances melanin production in human melanocytes, zebrafish, and human skin samples without causing toxicity, potentially through inhibiting PDE to increase cAMP levels and promote the melanin biosynthesis pathway.

This review summarizes the historical and evolving treatments for vitiligo, highlighting that combining medical and surgical approaches may enhance repigmentation outcomes, though more research and new protocols are needed.

This study observed that melanogenesis in human hair follicles is linked to anagen phases, with melanocyte activity and enzyme expression being region-specific to the nascent bulb.

This review examines cell senescence pathways in melanocytes, highlighting the involvement of telomere attrition, the p16/RB pathway, and cAMP signaling in the context of melanoma development, but reports no new findings.

This study demonstrated that a c-Kit-CreER-driven mouse model confirms melanocyte stem cells as a genuine source of melanoma, paralleling human melanoma in heterogeneity and gene signatures.

This study found that stressed dermal fibroblasts significantly increased dopa oxidase activity in melanocytes from hair, skin, and eyes, suggesting the involvement of fibroblast-derived factors like basic Fibroblast Growth Factor.

A man's scalp hair loss was due to a combined melanocytic nevus and alopecia areata, suggesting a possible link between the two conditions.

This study discovered that the gene Tfap2b identifies a melanocyte stem cell population in zebrafish, essential for regenerating melanocytes with multi-fate potential into adult pigment cells.

This study found that Wnt signaling in the hair follicle is crucial for coordinating the behavior of epithelial and melanocyte stem cells, which drives hair regeneration and melanocyte differentiation in mice.

This review discusses the identification and characteristics of melanocyte stem cells, emphasizing their role in hair pigmentation, greying, and skin repigmentation, but reports no new research findings.

This article describes protocols for isolating and expanding human epidermal neural crest stem cells and discusses their potential for cell-based therapies in regenerative medicine, but reports no new clinical results.

This review discusses melanocyte development, emphasizing the plasticity of melanoblasts and the role of both intrinsic and extracellular signals in their differentiation and migration, with no new clinical results reported.

This study found that ionizing radiation primarily affects keratinocyte stem cells in the hair follicle, suggesting they play a central role in radiation-induced hair graying, rather than melanocyte stem cells.

This study found that gonadal steroid hormones influence alopecia areata in C3H/HeJ mice, with estradiol promoting progression and dihydrotestosterone conferring resistance to disease onset.

This review discusses the interactions between melanocyte stem cells and their niche in hair regeneration and repair, but reports no new results; recent studies on molecular pathways are highlighted.

Repigmentation in vitiligo may come from melanocyte stem cells in the skin.

This article discusses melanocyte development from neural crest cells and reports no new experimental results; the authors suggest a broader range of functions for melanocytes than previously recognized.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This paper provides a comprehensive review of melanocytes' roles in skin biology, focusing on their pigmentation and immune functions, and suggests potential research opportunities for preventing and treating skin disorders.

This review discusses the processes of melanocyte stem cell quiescence and activation, focusing on their interaction with hair follicle stem cells, and highlights current research on hair graying mechanisms; it reports no new results.

This research examined the transcriptional landscape of quiescent melanocyte stem cells (qMcSCs) in adult female mice, revealing significant heterogeneity within this cell population and identifying novel subpopulations that vary in immune privilege regulation, melanocyte differentiation potential, and neural crest potential.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This study found that individuals with alopecia areata showed differences in otoacoustic emissions, suggesting potential links between the condition and auditory dysfunction, with significant gender and age group variations observed in hearing test results.

This study observed that 5α‐dihydrotestosterone increased pigmentation in certain skin areas of male Syrian hamsters, while estradiol decreased melanocyte numbers and counteracted the androgen-induced pigmentation effects.

This study found that Wnt ligands from CD133-positive dermal papilla cells are essential for maintaining hair growth by supporting cell signaling between different hair follicle structures.

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.

In this case study, donor lymphocyte infusions effectively eradicated measurable residual disease in a patient with relapsed acute myeloid leukemia after hematopoietic cell transplantation, while side effects included the development of vitiligo and alopecia areata, likely due to chronic graft-versus-host disease.

This review discusses the classification and diagnosis of pregnancy-related skin conditions and reports no new clinical findings.
