MYF5 and Cachexia: Compared to LC-cachexia mice, in muscles of LC-cachexia and unloaded rodents, numbers of activated (Pax-7+ and Myf-5+) satellite cells (only in LC 30-days + 15-day I) were significantly reduced (−29% change), while no significant modifications in quiescent/regenerative potential (Pax-7+ and Myf-5-) cells or total satellite cell numbers were detected (Figure 6B and Figure 7A–C).
