[A dermomyotome in fish?].
The dermomyotome is a transient epithelial sheet that forms from the dorsal aspect of the somite. The dermomyotome gives rise to a variety of tissues, most importantly myotomal muscle and dermis. Despite the central importance of the dermomyotome in the development of amniotes, the question of its existence in lower vertebrates has been lastingly eluded. The combination of single-cell lineage tracing and gene expression analysis has recently led to the identification in fish of a somitic sub-domain that exhibits structural and functional features of the amniote dermomyotome.
