Article Abstract
The clinical need for effective bone regeneration in compromised conditions continues to drive demand for innovative solutions. Among emerging strategies, extracellular vesicles (EVs) have shown promise as an acellular approach for bone regeneration. However, their efficacy is hindered by rapid sequestration and clearance when administered via bolus injection. To address this challenge, EV-functionalized scaffolds have recently been proposed as an alternative delivery strategy to enhance EV retention and subsequent healing efficacy. This review aims to consolidate recent advancements in the development of EV-functionalized scaffolds for augmenting bone regeneration. It explores various sources of EVs and different strategies for integrating them into biomaterials. Furthermore, the mechanisms underlying their therapeutic effects in bone regeneration are elucidated. Current limitations in clinical translation and perspectives on the design of more efficient EVs for improved therapeutic efficacy are also presented. Overall, this review can provide inspiration for the development of novel EV-assisted grafts with superior bone regeneration potential.

Background: Bone infection induces a strong inflammatory response and leads to impaired bone regeneration, in which macrophages sense mechanistic signals and modulate immune responses in the inflammatory microenvironment through Piezo1. Nonetheless, the regulatory role of Piezo1 in macrophages during bone infection remains elusive.
Methods: Rat models of infected bone defects were established for bulk RNA sequencing and single-cell RNA sequencing.

In recent years, the incidence of orthopedic diseases has increased significantly, while traditional treatments often face limitations such as limited efficacy and pronounced side effects. The development of nanomedicine technology provides novel strategies for orthopedic disease treatment. As an emerging two-dimensional (2D) nanomaterial, black phosphorus nanosheets (BPNS) demonstrate remarkable potential in treating orthopedic diseases due to their unique physicochemical properties, superior biocompatibility, and the fact that their degradation product-elemental phosphorus-constitutes an essential component of bone tissue.

This review concentrates on the electroactive ceramic biointerfaces inspired by bone piezoelectricity for advanced ceramic biomaterials. Bone generates electrical potentials through the piezoelectric properties of collagen fibrils and apatite minerals under mechanical loading. These electrical signals influence osteoconductivity and regenerative capacity by osteogenic cells.

Background: Sjögren's syndrome (SS) is a chronic autoimmune disease delineated by excessive lymphocyte infiltration to the lacrimal or salivary glands, leading to dry eye and dry mouth. Exosomes secreted from mesenchymal stem cells (MSC) are known to have anti-inflammatory and tissue regeneration abilities. This study endeavored to demonstrate the effect of MSC-derived exosomes on the clinical parameter of dry eyes and associated pathology in SS mouse model.
