Effect of aging on recruitment of tenogenic progenitor during tendon-to-bone healing in a rat rotator cuff repair model

Although elderly patients have a higher rate of retear afterrotator cuff (RC) repair, the effects of aging on the tendon-to-bone healingprocess remain unclear. We previously reported that scleraxis (Scx)-positivetenogenic cells may form tough, tendon-like tissue in a rat RC healing model.Here, we aimed to investigate the effects of aging on the recruitment oftenogenic cells and the mechanical strength at the repair site during tendon-tobonehealing after RC repair in rats.
