... heterogeneous angles? Our own cyclopamine-treated embryos closely recapitulate the appearance of the original U-mutants; they lack muscle pioneers in early segmentation stages and they exhibit U-shaped myotomes at larval stages. However, the surprising observation of transient chevron shapes that mimic...

...Emmanuelle Dumont; Cecile Rallière; Pierre-Yves Rescan SUMMARY The external cell layer that surrounds the fish primary myotome provides the myogenic precursors necessary for muscle growth, suggesting that this epithelium is equivalent to the amniote dermomyotome. In this study we report...

... adaptations augmenting the delivery, transfer and utilization of O 2 by the red myotomal muscle (RM), which powers continuous swimming. Tuna swimming performance is enhanced by a unique anterior and centrally positioned RM (i.e. closer to the vertebral column) and by structural features (relatively small...

...Hélène Alami-Durante; Pierre Bergot; Michèle Rouel; Geoffrey Goldspink ABSTRACT A study was conducted on common carp ( Cyprinus carpio L.) to determine the effects of environmental temperature experienced by embryos and larvae on the development of myotomal white muscle. Eggs from one female were...
