The debilitating effects of rotator cuff tears and the high incidence of failure associated with current grafts underscore the clinical demand for functional solutions for tendon repair and augmentation. To address this challenge, we have designed a poly(lactide-co-glycolide) (PLGA) nanofiber-based scaffold for rotator cuff tendon tissue engineering. In addition to scaffold design and character...

Introduction: Poly lactic co- glycolic acid (PLGA) and poly caprolacton (PCL) are highly applicable polymers in the field of drug delivery and tissue engineering scaffolds. Therefore, this study aimed to design an insulin-loaded PCL/PLGA hybrid nanofiber scaffold in order to be applied in attachment and growth of chondrocytes. Moreover, it can provide a vehicle for the controlled release of a...

Tissue engineering techniques using novel scaffolding materials offer potential alternatives for managing tendon disorders. An ideal tendon tissue engineered scaffold should mimic the three-dimensional (3D) structure of the natural extracellular matrix (ECM) of the native tendon. Here, we propose a novel electrospun nanoyarn network that is morphologically and structurally similar to the ECM of...
