摘要
The genes required for stem cell specification and lineage restriction during embryogenesis also play fundamental roles in adult tissue regeneration and cancer. This "development-regeneration-cancer" axis is exemplified by the vertebrate pigmentation system. Melanocytes exhibit almost unlimited self-renewal capacity during regenerative processes such as mammalian hair recoloration and zebrafish fin regeneration. Melanoma utilizes many regulatory signals and pathways required during ontogeny and regeneration. A discussion of these interconnections highlights how studies of stem cell function in embryonic and regenerative contexts can yield insights into melanoma biology.
