Despite their significant regenerative potential, the clinical application of EVs remains limited by rapid clearance, insufficient local retention, and uncontrolled release following administration. To address these challenges, various extracellular matrix (ECM)-based and ECM-bioinspired scaffolds have been developed as delivery platforms. These scaffolds can provide structural support and enable controlled, localized release of EVs. This narrative review critically evaluates the current evidence regarding scaffold systems as EV delivery platforms for dental pulp regeneration, comparing their biological performance, methodological quality, and translational potential. Across the available studies, scaffold-assisted EV delivery consistently enhanced angiogenesis, odontogenic differentiation, mineralization, and immunomodulation; however, the evidence remains preclinical and is characterized by substantial heterogeneity regarding EV source, isolation and characterization methods, scaffold composition, experimental models, and outcome assessment. Current findings support the feasibility of scaffold-assisted EV delivery for regenerative endodontics, but important challenges remain, including standardization of EV production and characterization, scalable manufacturing, regulatory approval, and demonstration of long-term safety and functional pulp-dentin complex regeneration.

They contain abundant functional metabolites, especially a group of vanillylamide compounds belonging to the family of capsaicinoids, which have been exploited for medicinal, nutritional, agricultural, and cosmetic uses. The demand for capsaicinoid molecules is increasing day by day due to their high economic value and wide range of applications. Therefore, increasing bioactive metabolites, especially capsaicinoids in chilli peppers, is a major priority in the current scenario. Multi-omics approaches such as genomics, transcriptomics, proteomics, and metabolomics have substantially contributed to understanding the complex regulatory networks governing capsaicinoid biosynthesis. Key structural genes, transcription factors, and signaling pathways involved in the phenylpropanoid and branched-chain fatty acid pathways have been identified, providing valuable targets for metabolic engineering in chilli pepper. Despite these advances, the integration of genetic modification approaches for the targeted enhancement of capsaicinoid production remains limited in chilli pepper. Recent developments in biotechnology, particularly CRISPR/Cas-mediated genome-editing, enable the precise genetic modification of metabolic pathways and regulatory networks in plants. Therefore, it can contribute to the precise modification of key genes involved in the capsaicinoid biosynthesis pathway, offering potential strategies to enhance the capsaicinoid content in chilli pepper.
