摘要:

胞外囊泡(EVs)是不同细胞间及多种组织间信号交流的重要途径,广泛参与组织发育、稳态维持和再生修复等过程。间充质干细胞(MSCs)分泌的EVs含有丰富的生物活性物质,是MSCs发挥促组织再生作用的重要分泌性成分之一。近年来,MSCs分泌的EVs(MSC-EVs)在牙及颌面组织修复再生中的研究取得快速进展。MSC-EVs已被证实可以有效促进牙及颌骨中干细胞和前体细胞的增殖、分化、存活、迁移,并加快血管神经再生,从而可应用于牙髓、牙周、颌骨、颞下颌关节及颌面软组织的再生。因为EVs具备免疫原性低、作用途径广、可规模化制备等优势,其临床应用潜力巨大。随着对EVs作用机理的深入探索和标准化制备及检测体系的建立,MSC-EVs治疗有望成为牙及颌面部组织再生的重要策略。

Abstract:

Extracellular vesicles (EVs) are the essential mediators of communication between different cells or tissues. EVs participate in the development, homeostasis, repair, and regeneration of tissues. Mesenchymal stem cells(MSCs) secrete a range of bioactive factors, which are important in MSC-mediated tissue regeneration. Great progress has been made in the research of EVs derived from MSCs (MSC-EVs) in the regeneration of dental and maxillofacial tissues. Emerging evidence confirmed that MSC-EVs can efficiently modulate the proliferation, differentiation, survival, and migration of stem or progenitor cells and stimulate the regeneration of the neurovascular system. MSC-EVs have been used in regenerating dental pulp, periodontium, jawbone, temporomandibular joint, and maxillofacial soft tissues. Having the advantages of low immunogenicity, versatile function, and suitability for large-scale production, EVs have excellent clinical application prospect. Along with investigations on molecular mechanisms of action and development of standard manufactory and testing systems, therapies u-sing MSC-EVs are promising strategies for regenerating dental and maxillofacial tissues.
