Images and histological changes in mid/distal regions of flexor digitorum tendons. A Bonar scoring system was used to rate the histological findings. a-e Representative images of forearm flexor digitorum tendons at the level of the wrist. Inset in Panel c shows a different TASK-Tx rat’s mid flexor digitorum tendon. f-i Tendon scores of cell shape, cellularity, collagen organization and presence of immune cells, respectively. j-l Epitendon of thickness, cellularity, and presence of immune cells. Scale bars in each image = 50 μm. Abbreviations: Epi = epitendon; N = a median nerve branch. Symbols: *: p < 0.05 and **: p < 0.01, compared to TASK-Tx group; &: p < 0.05 and &&: p < 0.01, compared to a control group as shown. Mean ± 95% CI shown
