Among various MSC sources, Wharton's Jelly-derived MSCs (WJ-MSCs) are emerging as a promising candidate due to their superior proliferative capacity and ethical advantages. However, a critical challenge in stem cell-based therapies is the need for robust, non-invasive quality assessment methods to ensure biosafety and bioefficacy. Traditional evaluation techniques, such as enzyme-linked immunosorbent assay (ELISA) and liquid chromatography-mass spectrometry (LC-MS), offer limited real-time detection and require complex sample processing. Surface Plasmon Resonance (SPR) biosensors provide a real-time, label-free alternative for assessing MSC secretomes, particularly the quantification of key bioactive molecules such as hepatocyte growth factor (HGF) and c (VEGF). This review explores the design, application, and challenges of SPR-based biosensing for secretome analysis in WJ-MSC quality assessment. The principles of SPR, key biosensor design parameters, and the role of HGF and VEGF are also discussed as critical biomarkers in evaluating the therapeutic potential of WJ-MSCs. Future research should focus on optimizing ligand immobilization strategies, improving sensitivity for low-concentration secretomes, and aligning SPR-based assessments with regulatory guidelines to facilitate its adoption in regenerative medicine.</p>","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":" ","pages":"e02045"},"PeriodicalIF":9.6,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145237499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lyophilization has emerged as a promising alternative approach; however, suboptimal outcomes remain owing to the challenge of lyoprotectant delivery into EVs. Here, the atypical transport property of the EV membrane is unraveled, and lyoprotective trehalose is delivered into EVs by combining substantial hypotonicity (below intravesicular colloid osmolality) and mild heat shock (42 °C). Consequently, the lyophilization of trehalose-laden EVs is notably enhanced, with less EV loss, more RNA and protein retention, and superior therapeutic efficacy. Moreover, the EVs can be co-reconstituted and co-lyophilized with hyaluronic and methylcellulose (HAMC) hydrogel carriers, yielding excellent preservation outcomes and controlled EV release. Lyophilized EVs or HAMC-EVs maintain Treg cell regulation in vitro and experimental autoimmune encephalomyelitis disease treatment in vivo.

Herein, this study introduces a photothermally activated pyroelectric-enhanced self-powered wound dressing designed to overcome this limitation through a synergistic tri-modal mechanism integrating photothermal, pyroelectric, and piezoelectric effects. The wound dressing comprises a dual-layer architecture: an outer layer of hydrophobic poly(vinylidene fluoride) (PVDF)/cotton-based electrostimulation film and an inner hydrophilic self-adhesive hydrogel layer. Upon NIR irradiation, the hydrogel layer undergoes localized photothermal heating, dynamically reducing interfacial impedance (≈10× increase in conductivity) and facilitating efficient charge migration across the interface. Concurrently, the NIR-induced photothermal effect activates pyroelectric polarization in the PVDF layer, which synergistically couples with piezoelectric output to generate an enhanced endogenous electric field (≈1.5× the electric field of piezoelectric-only effects). In vitro and in vivo studies showed that this dressing significantly promoted wound healing. Compared with the control group (on the 7th day), the inflammatory chemokine density reduced by 99.36×, the capillary density increased by 3.85×, resulting in a 2.59× enhancement in the wound healing rate.
