Cell of Origin Contributes to Melanoma Diversity

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 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 found that epidermal melanocytes can regenerate hair follicles, whereas non-cutaneous or dermal melanocytes cannot, suggesting two distinct melanocyte lineages with potential implications for melanocyte-related diseases.

This review examines the differential aging of melanocytes in hair follicles and skin, and reports no new findings; the authors suggest further research is needed to understand these processes.
