Abstract:
ObjectsOsteoarthritis (OA) is a widespread degenerative joint condition commonly occurring in older adults. Currently, no disease-modifying drugs are available, and safety concerns associated with commonly used traditional medications have been identified. In this review, a significant portion of research in this field is concentrated on cartilage, aiming to discover methods to halt cartilage breakdown or facilitate cartilage repair.MethodsResearchers have mainly investigated the cartilage, seeking methods to promote its repair. This review focuses on peptide-based molecules known for their ability to selectively bind to growth factor cytokines and components of the cartilage extracellular matrix.ResultsChondroinductive peptides, synthetically producible, boast superior reproducibility, stability, modifiability, and yield efficiency over natural biomaterials. This review outlines a chondroinductive peptide design, molecular mechanisms, and their application in cartilage tissue engineering and also compares their efficacy in chondrogenesis in vitro and in vivo.ConclusionsIn this paper, we will summarize the application of peptides engineered to regenerate cartilage by acting as scaffolds, functional molecules, or both and discuss additional possibilities for peptides. This review article provides an overview of our current understanding of chondroinductive peptides for treating OA-affected cartilage and explores the delivery systems used for regeneration. These advancements may hold promise for enhancing or even replacing current treatment methodologies.
