Satellite cells are resident stem cells of skeletal muscle; they are normally quiescent but upon post-trauma activation start to proliferate and fuse with damaged fibers contributing to muscle regeneration. In this study the effect of the bioactive sphingolipid sphingosine 1-phosphate (S1P) on the proliferative and migratory response of murine satellite(More)
Insulin-like growth factor-1 (IGF-1) is the most important physiological regulator of skeletal muscle progenitor cells, which are responsible for adult skeletal muscle regeneration. The ability of IGF-1 to affect multiple aspects of skeletal muscle cell biology such as proliferation, differentiation, survival and motility is well recognized, although the(More)
Sarcopenia represents a major health problem highly prevalent in elderly and age-related chronic diseases. Current pharmacological strategies available to prevent and reverse sarcopenia are largely unsatisfactory thus raising the need to identify novel targets for pharmacological intervention and possibly more effective and safe drugs.

Regulation of the motility of skeletal muscle precursor cells, such as satellite cells, is critically important for their proper recruitment at the site of tissue damage, and ultimately for its correct repair. Here we show that lysophosphatidic acid (LPA), which is well-recognized as a powerful bioactive agent, strongly stimulates cell migration of(More)
