In this study, collagen I decellularized scaffolds enhanced the growth and melanotic properties of hair follicle melanocytes, suggesting their potential as effective carriers for transplantation in vitiligo treatment.

This study observed that fetal hair follicle melanocytes varied in morphology and development stages, with melanosomes undergoing degradation into irregular pigment particles within keratinocytes.

The researchers reported that protocatechuic acid reduced melanin synthesis and enhanced antioxidant activity in cultured human hair follicle melanocytes, indicating potential for skin whitening applications.

This study adapted a method for culturing melanocytes from human hair follicles to horses, successfully creating partially melanotic equine melanocytes, potentially advancing hair follicle biology research across species.

This review discusses melanocytes' role in pigmentation, their clinical significance in conditions like vitiligo and hair graying, and highlights current research on hair follicle regeneration without reporting new clinical results.

In this study, Dguok deficiency in mice led to premature hair greying due to a loss of melanocyte stem cells and mature melanocytes, with increased oxidative stress and cell death; treatment with an antioxidant mitigated these effects, suggesting DGUOK's importance in hair pigmentation maintenance.

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 study concluded that lenalidomide significantly induces the proliferation and migration of melanocyte stem cells, enhancing their differentiation into functional melanocytes in a mouse model.

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 laboratory study found that collagen matrices with high-sulfated hyaluronan may enhance the cultivation of human keratinocytes and melanocytes from hair follicles for epidermal graft development.

In this study, researchers found that deleting the Bmi1 gene in murine melanocytes caused premature hair greying and loss of melanocyte lineage cells, highlighting BMI1's role in protecting melanocyte stem cells from stress and oxidative damage.

Hair follicle-derived melanocyte transplant could effectively treat vitiligo by restoring skin color.

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 found that stress-induced inactivation of the enzyme Dicer in melanocytes can cause premature hair greying by preventing proper melanocyte placement and melanin transfer in mice, suggesting the Dicer-miR92b-ItgaV pathway as an important link between stress and grey hair.

This study found that co-culturing adipose-derived stem cells with hair follicle-derived melanocytes, combined with narrowband UVB, significantly improved pigmentary response in treating stable, resistant vitiligo compared to non-UVB treatments.

This study found that betamethasone increased tyrosinase activity and melanin content in amelanotic melanocytes from human hair follicles, suggesting a potential mechanism for glucocorticoid treatment in vitiligo.

COL17A1 is crucial for preventing hair graying and loss by supporting hair and pigment stem 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 role of intrinsic skin signals, rather than serum signals, in regulating melanin synthesis and hair pigmentation, but reports no new experimental data.

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 study found that quercetin increased melanin production in hair follicle tissues from C3H/HeN Jel mice, correlating with higher levels of tyrosinase protein and TRP-2 protein expression.

This study found that endothelin-1 increases adhesion and chemotaxis of amelanotic melanocytes on fibronectin, laminin, and collagen IV, potentially through changes in the actin cytoskeleton.

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

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 identified exosomal miR-199a-3p as a key factor in the regulation of melanogenesis by dermal papilla cells, finding that it enhances melanocyte proliferation and melanin production, suggesting potential therapeutic targets for pigmentation disorders.

This study observed that albino rats, despite not producing melanin, have melanocytes localized in specific skin areas of their hair matrix, suggesting that gene expression analysis of their skin should consider regional differences in melanocyte presence.

In this murine study, researchers found that topical treatment with Philippine stingless bee propolis increased folliculogenesis, epidermal thickness, and melanogenesis, but not hair length, potentially supporting hair follicle regeneration and melanocyte function in chemotherapy-induced alopecia models.

This study observed that melanocytes in the outer root sheath of fetal scalp hair follicles may act as stem cells, showing rapid proliferation but immature function and morphology in culture.

This study found that stem cell factor combined with fibronectin and type IV collagen promotes migration of amelanotic melanocytes, which may help explain their movement during vitiligo repigmentation.

This article discusses recent findings on hair graying involving melanocyte stem cell maintenance and key regulatory molecules, and reports no new experimental results.
