Compared to unloaded animals, in muscles of mice with the two conditions (LC-cachexia and unloading), a significant decrease in the number of activated (Pax-7+ and Myf-5+) satellite cells (only in LC 30-days + 15-day I, −32% change) was observed, while counts of quiescent/regenerative potential (Pax-7+ and Myf-5-) cells and of total satellite cells did not significantly differ (Figure 6A,B and Figure 7A–C). Here, MYF5 is linked to Cachexia.
