This study found that BMP signaling is involved in regulating melanogenesis, pigment transfer, and melanocyte migration, contributing to our understanding of skin pigmentation mechanisms.

This study found that human skin melanocytes with low mutation burdens are smaller, less dendritic, and exhibit stem-like features, often residing in UV-protected hair follicles, suggesting their role in replenishing sun-damaged epidermis.

This research describes methods to activate melanocyte stem cells during hair follicle regeneration and to isolate melanocytes from neonatal mouse skin, with the aim of studying melanogenesis for potential clinical applications.

The human hair follicle can store topical compounds and be targeted for drug delivery with minimal side effects.

This review discusses the isolation, structure, and bioactivity of lignans and neolignans from 2016 to mid-2018, reporting no new clinical results but highlighting their potential protective properties against diseases such as cancer and neurodegeneration.

The FTO gene hinders stem cells in hair follicles from becoming pigment cells.

This study found that Sox2 and BMP signaling may be key regulators of pigmentation and melanocyte migration, as suggested by experiments in mice, human biopsies, and cell co-cultures.

This study suggests that a purified sphingolipid fraction can activate melanocyte stem cells via p38 signalling, potentially offering a non-UV-based treatment for vitiligo, though additional validation is needed.

This review discusses segmental vitiligo as part of the vitiligo clinical spectrum and highlights its role as a model for studying repigmentation, but reports no new clinical results.

This review discusses recent research on melanocyte stem cells and explores the differences between mouse and human skin, but it reports no new clinical results.

Hair graying may help prevent cancer by protecting stem cells.

This review discusses the roles and characteristics of skin stem cells, their niches, and signaling pathways in skin maintenance, aging, and cancer, highlighting their potential in therapeutic applications but presenting no new clinical findings.

This review discusses the biology of hair follicle stem cells and highlights their potential for applications in regenerative medicine, drug, and gene delivery, but reports no new clinical results.

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

This article reviews the process of repigmentation in vitiligo and emphasizes the role of UV light as the most potent stimulus, with no new clinical findings reported.

This article explores the use of monoclonal antibodies to study the presence and distribution patterns of melanocytes in developing human skin, but reports no new clinical results.

This chapter reviews recent developments in vitiligo research, highlighting the role of melanocyte stem cell differentiation and oxidative stress in its management, but reports no new clinical results.

This study reports that hair follicle neural crest stem cells in mice can be differentiated into melanocytes, potentially aiding repigmentation in vitiligo-affected areas.

This study concluded that controlled micro-injury induces hair regeneration and vitiligo repigmentation in mice, potentially through the Wnt/β-catenin pathway.

This manuscript suggests that exogenous hydrogen peroxide is a primary risk factor for higher incidence of cutaneous melanoma in swimmers, with UV radiation playing a secondary role.

This study observed that Langerhans cells and melanocytes migrated to hair follicle sites during human embryogenesis, suggesting that Langerhans cells acquire immunoregulatory properties there.

In this study, different types of catagen in the C57BL/6 mouse model exhibited varying effects on hair follicle melanocytes and melanin distribution, with spontaneous and dexamethasone-induced catagen showing pigment incontinence, while cyclophosphamide-induced catagen retained dendritic melanocytes but increased ectopic melanin.

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.
