Myogenesis and hormonal control of muscle growth
Résumé
This chapter summarizes current research on the molecular, genetic and cellular bases of skeletal muscle development and growth in the trout [i]Oncorhynchus mykiss[/i]. The myogenic transcriptional network is examined in relation with the transient sub-compartmentalization of the early somites that results in the formation of distinct myogenic cell populations involved in distinct phases of myogenesis. The importance of the endocrine and paracrine regulation of muscle growth is also discussed with special reference to the influence of environmental factors ont the GH-IGF system. Insights from [i]in vitro[/i] models ares also provided.
