Figure 3 Acute endurance exercise promotes dynamic secretion of exosomes from skeletal muscle
Figure 3 | Acute endurance exercise promotes dynamic secretion of exosomes from skeletal muscle. C57BL/6 mice (male; 3 months old; n = 6 per group) were divided into sedentary (SED) and acute exercise groups, with the latter subjected to acute endurance exercise (acute END; 15 m/min for 90 min on a motorized treadmill). Animals were immediately sacrificed after exercise and soleus muscle was fixed in 4% paraformaldehyde. Representative immunofluorescence images of ALIX (exosomal marker protein; red) and DAPI (nuclei; blue) in soleus from sedentary and acute exercised mice are shown. An appreciable and stark decrease in ALIX staining after exercise is seen, signifying the release of exosomes from muscle. A similar effect was observed in all mice used in the study (A. Safdar, A. Saleem and M. A. Tarnopolsky, unpublished work).
