HSA-rtTA transgene drives robust myofiber expression of tetracycline-responsive H2B-GFP transgene. a Representative single fiber images of hind limb muscles taken from HSA-GFP mice (n = 4) treated with doxycycline. Single fiber images show robust myonuclear GFP expression in muscles composed of slow- and fast-twitch fibers. b Quantification of GFP+ myonuclei of single fibers from hind limb skeletal muscles (plantaris, gastrocnemius, soleus, tibialis anterior (TA), and extensor digitorum longus (EDL)) of HSA-GFP mice showed greater than 95% of all DAPI+ myonuclei within a fiber were GFP+. The gray bar represents the average percentage of GFP-positive myonuclei (n = 4) for each muscle
