Migration of melanocytic lineage-derived cells

Au cours du développement embryonnaire chez les vertébrés, la migration des mélanocytes et de leurs précurseurs, les mélanoblastes, le long de l’axe dorso-latéral et le franchissement de la membrane basale séparant le derme de l’épiderme permettent leur localisation au niveau des zones interfolliculaires et folliculaires des poils. La transformation néoplasique convertit les mélanocytes en cellules de mélanome fortement invasives pouvant adopter deux modes de migration interconvertibles. Cette revue décrit comment les mutants naturels de souris, les modèles générés par ciblage génique et les systèmes de culture in vitro, ont permis l’identification des gènes, des voies de signalisation et des mécanismes qui régulent la migration des cellules normales et pathologiques du lignage mélanocytaire.
Abstract
During development, neural crest cells-derived melanoblasts migrate along the dorso-lateral axis into the dermis, then cross the basal layer to reach the epidermis and differentiate into melanocytes. They finally colonize the hair follicles to become resident pigmented cells. Neoplastic transformation converts melanocytes into highly invasive melanoma cells, which can adopt two modes of interconvertible migration (mesenchymal and amoeboid). Through analysis of the coat color phenotype of natural mouse mutants and genetically modified animals, many of the genes regulating migration were identified. Deciphering of cell membrane protrusions and signaling molecules involved in melanoma cell motility was further achieved through 2D and 3D culture systems. Here, we summarize how these data allow a better understanding of the complex mechanisms controlling migration of normal and pathological cells of the melanocytic lineage.
