Recent work in teleosts has renewed interest in the dermomyotome, which was initially characterized in the late 19th century. We review the evidence for the teleost dermomyotome, comparing it to the more well-characterized amniote dermomyotome. We discuss primary myotome morphogenesis, the relationship between the primary myotome and the dermomyotome, the differentiation of axial muscle, appendicular muscle, and dermis from the dermomyotome, and the signaling molecules that regulate myotome growth from myogenic precursors within the dermomyotome. The recognition of a dermomyotome in teleosts provides a new perspective on teleost muscle growth, as well as a fruitful approach to understanding the vertebrate dermomyotome.
硬骨鱼的近期研究重新引发了人们对肌节的兴趣,肌节最初是在19世纪末被描述的。我们回顾了硬骨鱼肌节的相关证据,并将其与特征更为明确的羊膜动物肌节进行比较。我们讨论了初级肌节的形态发生、初级肌节与肌节之间的关系、轴肌、附肢肌和真皮从肌节的分化,以及调节肌节中肌源性前体细胞生长的信号分子。硬骨鱼中肌节的发现为硬骨鱼肌肉生长提供了新的视角,也为理解脊椎动物肌节提供了富有成效的方法。
