Lipid content is not altered in tenotomized supraspinatus at 2D or 15D. a Axial sections of in vivo magnetic resonance imaging (MRI) of a rat 15 days after unilateral RTC tear. When fat suppression is turned off, the white signal represents fat (note the obvious white signal from subcutaneous fat, red arrow). Fat was not detected in any axial sections in the torn supraspinatus (outlined by white dotted line). A longer (> 2 h), more detailed MRI scan of supraspinatus muscles ex vivo corroborated this finding. b Neutral lipids were stained in cross-sections from the mid-belly of the supraspinatus using Bodipy-493/503 and quantified (c) using ImageJ. No differences in intramyocellular lipid at 2D and 15D were found compared to controls. Scale bar represents 50 μm. All data are presented as mean ± SD, p < 0.05
