This study found that carvone, a plant-derived compound, decreases melanin content and inhibits melanoma cell proliferation through the cAMP pathway, suggesting potential benefits for treating melanomas and other hyperpigmentation disorders.

This study found that administering mesenchymal stem cells to UV-exposed mice reduced melanin levels, although the decrease was not statistically significant.

This study identified a small population of PAX3+/CD34+ cells in human foreskin tissue that may serve as transition cells between melanocyte stem cells and hair follicle stem cells, characterized by specific marker expressions.

This study focused on the ultrastructural and immunohistochemical aspects of dermal mast cells in systemic mastocytosis and their interaction with the epidermal melanin unit.

This study found that melanocyte progenitor cells are present in human subcutaneous adipose tissue and may differentiate into mature melanocytes, suggesting potential applications in treating skin diseases and rejuvenation.

In this study, researchers successfully generated functional and long-lived melanocytes from human embryonic stem cells, demonstrating their biocompatibility and high engraftability in mice, which may aid in developing treatments for pigmentary skin disorders.

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 study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

This study found that when human hair follicles were grafted onto mice, they progressed through dystrophic stages and returned to normal growth, with stem cells aiding in recovery.

In this study, the combination of SCF and ET-1 was found to significantly enhance skin pigmentation and melanin content in human skin xenografts on SCID mice compared to either treatment alone.

In this study, silencing BMAL1 and PER1 genes increased melanogenic activity in follicular and epidermal melanocytes, suggesting that peripheral circadian clocks may regulate melanin pigmentation.

This study found that finasteride decreases melanin levels in melanocyte and melanoma cells by inhibiting MC1R, without causing cytotoxicity, suggesting its potential role in regulating melanogenesis.

In this study, Epimedii Folium extract was found to enhance melanin production and promote pigmentation through mechanisms involving the MAPK/ERK1/2 pathway in both in vitro and in vivo models.

In this study, exosome-like nanoparticles derived from rose stem cell culture were found to enhance skin quality by increasing collagen production, reducing melanin and inflammation, and promoting cell migration in vitro, suggesting potential aesthetic applications.

This study found that ALRN-6924 effectively protected human hair follicles from cyclophosphamide-induced damage in an ex vivo setting, suggesting it may reduce both acute and permanent chemotherapy-induced alopecia.
