Fecha de publicación: | 2015 | Editor: | John Wiley & Sons | Citación: | Pigment Cell and Melanoma Research 28(2): 196-209 (2015) | Resumen: | Dorso-ventral pigment pattern differences are the most widespread pigmentary adaptations in vertebrates. In mammals, this pattern is controlled by regulating melanin chemistry in melanocytes using a protein, agouti-signalling peptide (ASIP). In fish, studies of pigment patterning have focused on stripe formation, identifying a core striping mechanism dependent upon interactions between different pigment cell types. In contrast, mechanisms driving the dorso-ventral countershading pattern have been overlooked. Here, we demonstrate that, in fact, zebrafish utilize two distinct adult pigment patterning mechanisms – an ancient dorso-ventral patterning mechanism, and a more recent striping mechanism based on cell–cell interactions; remarkably, the dorso-ventral patterning mechanism also utilizes ASIP. These two mechanisms function largely independently, with resultant patterns superimposed to give the full pattern | Descripción: | 5 figuras, 14 páginas | Versión del editor: | http://dx.doi.org/10.1111/pcmr.12335 | URI: | http://hdl.handle.net/10261/111801 | DOI: | 10.1111/pcmr.12335 | ISSN: | 1755-1471 | E-ISSN: | 1755-148X |
