Articular cartilage tissue engineering with stem cells implanted onto nanoscaffolds and platelet-rich plasma

Abstract

<p class="abstract">Musculoskeletal medicine targets both cartilage regeneration and healing of soft tissues. Articular cartilage repair and regeneration is primarily considered to be due to its poor regenerative properties. Cartilage defects due to joint injury, aging, or osteoarthritis have low self-repair ability thus they are most often irreversible as well as being a major cause of joint pain and chronic disability. Unfortunately, current methods do not seamlessly restore hyaline cartilage and may lead to the formation of fibro- or continue hypertrophic cartilage. Deficiency of efficient modalities of therapy has invited research to combine stem cells, scaffold materials and environmental factors through tissue engineering. Articular cartilage tissue engineering aims to repair, regenerate, and hence improve the function of injured or diseased cartilage. This holds great potential and has evoked intense interest in improving cartilage therapy. Platelet-rich plasma (PRP) and/or stem cells may be influential for tissue repair as well as cartilage regenerative processes. A great promise to advance current cartilage therapies toward achieving a consistently successful modality has been held for addressing cartilage afflictions. The use of stem cells, novel biologically inspired scaffolds and, emerging nanotechnology may be the best way to reach this objective via tissue engineering. A current and emergent approach in the field of cartilage tissue engineering is explained in this review for specific application. In the future, the development of new strategies using stem cells seeded in scaffolds and the culture medium supplemented with growth factors could improve the quality of the newly formed cartilage<span lang="EN-IN">.</span></p>
