This study observed two cases of pigmented epithelioid melanocytoma suggesting potential differing origins: one from a hair follicle's outer root sheath and another from an intradermal nevus.

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

This review discusses how the CRH/POMC systems may regulate human hair follicle pigmentation and highlights the concept of "self-similarity" in melanocortin systems at both local and systemic levels, without presenting new experimental results.

This study reports that the side population technique can isolate melanocyte stem cells from human hair follicles, potentially allowing them to be used for skin pigmentation repopulation.

This study describes how feather pigmentation in birds is regulated by melanocyte distribution, differentiation, and patterned agouti expression, contributing to diverse and adaptive color patterns.

This study demonstrates that stem cells from human foreskins, which lack hair follicles, can differentiate into melanocytes and migrate to the epidermis, potentially altering our understanding of pigmentation disorders.

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

This review discusses the biology and development of skin melanocytes, but reports no new clinical findings.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

Fibroblasts can be turned into melanocytes for potential skin treatments.

This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

In this case report, a rare melanotrichoblastoma tumor was identified in a 51-year-old female following the histological and immunohistochemical analysis of a lesion on the pubo-inguinal area, presenting with strong epithelial marker positivity and a low proliferative index.

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 found that p21 is much more highly expressed in normal melanocytes compared to melanoma cells, suggesting a potential target for preventing melanoma progression through cell cycle repair processes.

In this study, all-trans retinoic acid was found to promote differentiation and inhibit proliferation of amelanotic melanocytes from human hair follicles, suggesting a potential role in melanogenesis.

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 non-pigmented hair follicles have significantly lower expression of nucleotide excision repair genes, which may be associated with reduced melanin production capacity in these follicles.

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 oxidative stress in hair follicle melanocytes contributes to premature aging and apoptosis, providing insights into graying as a model for studying aging and testing antiaging therapies.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This review discusses melanocyte biology and its genetic and molecular basis, highlighting its relevance in understanding diseases like vitiligo and albinism, and reports no new findings.

This study reported successful and cosmetically acceptable repigmentation of leukoderma in three patients using minigrafts of normally pigmented, autologous skin.

This study found that human iPSC-derived melanocytes from vitiligo patients successfully integrated into mouse hair follicles and epidermis, demonstrating potential for personalized therapy for depigmentation.

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 study found that minoxidil accumulated in pigmented hair follicle cells more than in unpigmented ones, but this targeting by pigmentation did not affect hair growth.

This study found that in chimaeric mice models, the pigment distribution and pattern were influenced by the sash genotype, demonstrating the melanocyte-autonomous nature of the beige and leaden loci.

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

This review discusses transplantation of melanocyte stem cells for vitiligo treatment and reports no new clinical results; it suggests the procedure could be effective in reactivating melanocyte precursors for repigmentation.

This study utilized a pigmented human epidermal equivalent model to incorporate melanocytes into the epidermis and found enhanced differentiation potential compared to conventional in vitro systems, reflecting in vivo cellular trajectories and highlighting melanocyte-to-keratinocyte communication pathways.
