Hydrogel, a polymer material with three-dimensional structure, has considerably expanded in research across multiple fields lately. However, the lack of comprehensive review integrating status hydrogel diverse hindered development hydrogel. This bibliometric analysis reviewed hydrogel-related over past decades, emphasizing evolution, status, and future directions within multitude fields, such as materials science, chemistry, engineering, physics, biochemistry molecular biology, pharmacology pharmacy, cell biotechnology applied microbiology, etc. We encapsulated applications potential wound healing, drug delivery, encapsulation, bioprinting, tissue electronic products, environment applications, disease treatment. study integrated current matrix system characteristics hydrogels, aiming to offer cross-field reference for researchers promote advancement research. Furthermore, we proposed novel reproducible paradigm, which can provide more trends trajectory field.

Spinal cord injury (SCI) is a devastating event for the central nervous system (CNS), often resulting in loss of sensory and motor functions. It profoundly affects both physiological psychological well-being patients, reducing their quality life while also imposing significant economic pressure on families healthcare system. Due to complex pathophysiology SCI, effective treatments promoting recovery remain scarce. Mesenchymal stem cell-derived exosomes (MSC-Exos) offer advantages such as low immunogenicity, good biocompatibility, ability cross blood-spinal barrier (BSCB). In preclinical studies, they have progressively shown efficacy SCI repair functional recovery. However, yield insufficient targeting MSC-Exos limit therapeutic efficacy. Currently, genetic engineering other preprocessing techniques are being employed optimize properties exosomes, thereby enhancing potential. Therefore, this paper provides an overview biogenesis exosomes. summarizes current approaches optimizing exosome performance. Additionally, it details mechanisms through which optimized provide neuroprotection explores potential combined involving hydrogels.

Objective: Because of the evolving nature tissue engineering scaffolds in treatment spinal cord injury (SCI), current study was carried out to evaluate research productivity SCI. Methods: Studies published from 2000 2025 were retrieved Web Science core collection with topics and scaffolds. The data analyzed visualized using VOSviewer network analysis software. Results: Among 1542 articles analyzed, annual publications surged 2019, stabilizing thereafter. U.S., China, Canada led productivity, Northwestern University Biomaterials journal being top contributors. Keyword revealed hotspots such as functional recovery, axonal regeneration, stem cells, hydrogels. Notably, hydrogels embedded genetically engineered cells emerged a pivotal trend, reflecting shift toward biomimetic combinatorial therapies. Collaboration networks highlighted intensified partnerships between Chinese North American institutions, signaling global interdisciplinary efforts. Conclusions: This provides first bibliometric roadmap for SCI, identifying key trends, influential entities, underexplored areas. rise international collaborations underscores opportunities targeted research. These findings guide researchers prioritizing high-impact journals, fostering partnerships, advancing novel scaffold designs bridge translational gaps SCI treatment.

Spinal cord injury (SCI) is a serious neurological disease with an extremely high disability rate. Most patients show loss of motor and sensory functions below the level injury. Current treatment protocols are based on early surgical decompression pharmacotherapy. However, efficacy these interventions suboptimal. Due to its complex pathophysiological mechanisms difficulty central nervous system (CNS) regeneration, exploring effective therapeutic remains daunting. Flavonoids secondary metabolites unique plants that have attracted attention in recent years for their potential now commonly used inflammation, tumors, other diseases. For SCI, related studies still exploring; some compounds, such as quercetin, fisetin, hesperetin, shown good anti-inflammatory anti-apoptotic properties, which help restore function injured spinal cord. flavonoids exhibit certain disadvantages, including poor solubility, low bioavailability, inability achieve long-term controlled release. Some proposed drug delivery strategies-including nanoparticles, hydrogels, collagen scaffolds-to enhance efficacy. In this paper, we summarize strategies SCI by searching relevant literature propose future research directions provide new ideas multimodal SCI.
