Figure 1: Satellite cell number differs between muscles and with age.
From: Muscle stem cells contribute to myofibres in sedentary adult mice
(a–g) Representative cross-sections showing Pax7+ satellite cells in the EDL, TA, gastrocnemius, plantaris, soleus, diaphragm and EOM muscles at 12 and 20 months in control Pax7+/+;RosaDTA/+ mice. Scale bar, 100 μm. Mean number of Pax7+ satellite cells per volume (mm3) of muscle at 12 months (dark blue, n=6 EDL, TA, n=7 other muscles) and 20 months (light blue, n=3 EDL, n=5 other muscles). Data are expressed as mean±1 s.e.m. for all graphs. Two-tailed student t-test, *P≤0.05.
