NANOSTRUCTURED SCAFFOLDS FOR BIOLOGY AND TISSUE ENGINEERING

Cartilage defects remain one of the most challenging musculoskeletal tissues to treat owing to its poor healing capacity. The lack of sufficient clinical treatments has led to a drive in tissue engineering advancements that combine chondrogenic cells with scaffolds to aid in cartilage regeneration. Nanoscale materials are commonly used in scaffold synthesis because of their ability to mimic the size of extracellular matrix (ECM). This review focuses on the use of nanostructured scaffolds in combination with cells for cartilage tissue engineering. We detail the fabrication methods and materials used to produce nanostructured scaffolds, with a focus on nano fibers and their role in modulating cell biology. Lastly, we discuss various techniques that further functionalize the nanostructured scaffolds to enhance cellular responses.
