In this study, topical inhibition of casein kinase 1 in mice was found to enhance melanocyte precursor migration and eumelanin production, suggesting potential applications for treating vitiligo and graying hair through KitL/c-Kit signaling pathway activation.

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 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.

This study found that stable regeneration of pigmented hairs in mice after severe wounding can occur when the wound is made during the anagen stage, influenced by Wnt and Kit signaling pathways.

This study found that transfecting alpaca melanocytes with miR-5110 altered gene expression related to pigmentation, specifically identifying pathways like MAPK and Wnt as involved in melanogenesis regulation, providing insights into miR-5110's role in pigmentation processes.

This review provides an in-depth analysis of the structure and function of c-kit activation, and its role in both normal physiological and pathological conditions, with no new research findings reported.

SPRY1 deficiency in skin cells causes stem cells to move to the skin surface, leading to increased pigmentation.

This study found that non-cutaneous melanocytes in mice are less sensitive to Kit signaling compared to cutaneous melanocytes, showing dependence on ET3 and HGF signaling.
