Heterogeneous muscle gene expression patterns in patients with massive rotator cuff tears - Fig 1

<p>(A) MRI demonstrating the approximate biopsy region, where only regions of apparent muscle were targeted. (B) Representative H&E image of a muscle-containing biopsy, with high levels of muscle degeneration. (C) Representative H&E image of a biopsy that did not contain muscle, demonstrating high cellularity and presence of larger vascular structures.
