Fig. 7. — Expressions of cleaved caspase-3 and caspase-9 in Achilles tendon. Left panel: photomicrographs of cleaved caspase-3-positive cells and cleaved caspase-9-positive cells. The sections were stained for cleaved caspase-3-positive cells (black arrows) and caspase9-positive cells (red arrows). The scale bar represents 250 μm. Right upper panel: percentage of cleaved caspase-3-positive cells. Right lower panel: percentage of cleaved caspase-9-positive cells. A, control group; B, Achilles tendon injury group; C, Achilles tendon injury and 2 mg/kg PDRN-applied group; D, Achilles tendon injury and 4 mg/kg PDRN-applied group; E, Achilles tendon injury and 8 mg/kg PDRN-applied group. PDRN, polydeoxyribonucleotide. ^*P<0.05 compared with the control group. ^#P<0.05 compared with the Achilles tendon injury group.
