Description

Significant advancements are evident in neural tissue engineering for repairing the central nervous system, involving various strategies like biomaterials, cell-based therapies, and growth factors [1]. These approaches are crucial for promoting axonal regrowth, myelination, and functional recovery after injury to the Central Nervous System (CNS) [1]. Concurrently, current strategies for repairing peripheral nerve injuries encompass microsurgical techniques, nerve grafts, artificial nerve conduits, and the application of diverse biomaterials and cell therapies to enhance axonal regeneration and functional recovery [2]. Challenges persist in developing more effective treatments for these complex injuries, prompting continuous innovation and research into future directions [2]. The goal remains to create more effective and sustained regenerative environments for both the CNS and Peripheral Nervous System (PNS) [1].

Recent advancements specifically in biomaterials tailored for neural tissue engineering and regeneration highlight crucial design principles, fabrication techniques, and functionalization processes [3]. These materials, including hydrogels, scaffolds, and nanoparticles, are engineered to precisely mimic the native neural microenvironment, which is essential for guiding nerve repair and achieving functional restoration [3]. Functional biomaterials are developed to possess specific bioactivities such as conductivity, biodegradability, and the capacity to release therapeutic agents in a controlled manner [7]. Such properties are vital for enhancing their overall efficacy in promoting nerve repair and ultimately restoring lost functions following neural damage [7].

The application of 3D printing technology has emerged as a key tool for creating neural scaffolds applicable in both central and peripheral nervous system regeneration [6]. Discussions around this technology involve the careful selection of suitable biomaterials and various design considerations crucial for optimizing scaffold architecture [6]. These advanced engineered constructs are designed to facilitate nerve repair by providing robust structural support and effectively guiding cellular growth [6]. Furthermore, micro- and nanotechnologies play an increasingly important role in advancing neural regeneration [4]. They are utilized to create precise scaffolds, deliver therapeutic agents with high specificity, and modulate cellular behavior at the microscale, thereby offering novel and highly targeted approaches for repairing damaged nervous tissue and improving functional outcomes [4].

Cell-based therapies, particularly those involving stem cell-derived exosomes, show immense therapeutic potential for neural regeneration, especially in treating central nervous system diseases [5]. These minute vesicles are crucial for carrying bioactive molecules capable of modulating inflammation, promoting neurogenesis, and supporting axonal sprouting, suggesting a significant paradigm shift in regenerative medicine approaches [5]. Comprehensive tissue engineering approaches involve a review of various biomaterials and techniques, emphasizing the critical role of scaffold design, cell encapsulation, and sophisticated growth factor delivery systems [8]. These elements are paramount in mimicking the native extracellular matrix, promoting neuronal survival, guiding axonal development, and ensuring functional integration post-injury [8].

Recent progress in biomaterials development for neural regeneration encompasses different classes, including natural polymers, synthetic polymers, and composites [9]. Key modifications focus on enhancing biocompatibility, improving neurotrophic factor delivery, and creating conductive pathways essential for effective nerve repair [9]. Specifically for the peripheral nervous system, the integration of stem cells and neurotrophic factors into designed and functionalized nerve guidance conduits is reviewed [10]. These specific techniques are vital for promoting successful axonal regrowth and achieving functional recovery following peripheral nerve injury [10].

Conclusion

Neural regeneration research is making significant strides in repairing both the central and peripheral nervous systems, focusing on a multifaceted array of strategies. A central theme involves the development and application of advanced biomaterials, including hydrogels, intricate scaffolds, and nanoparticles. These materials are meticulously designed to closely mimic the native neural microenvironment, offering crucial structural support and guiding nerve repair. These engineered biomaterials often possess specific functional properties, such as conductivity, controlled biodegradability, and the capacity for targeted delivery of therapeutic agents like growth factors and various neurotrophic factors. Alongside biomaterials, cell-based therapies are gaining prominence. This includes the exploration of stem cells and particularly stem cell-derived exosomes, recognized for their promising therapeutic potential to modulate inflammation, promote neurogenesis, and actively support axonal sprouting following injury. Cutting-edge technologies like micro- and nanotechnologies are pivotal, enabling the creation of exceptionally precise scaffolds and facilitating highly targeted drug delivery systems. Simultaneously, 3D printing technology is instrumental in fabricating complex neural scaffolds, which are vital for guiding cellular growth and ensuring proper tissue integration. Specific strategies for Peripheral Nervous System (PNS) repair frequently involve advanced microsurgical techniques, nerve grafts, and carefully designed nerve guidance conduits. For the Central Nervous System (CNS), the research focuses on overcoming inherent regeneration challenges to foster robust axonal regrowth and effective myelination. Ultimately, the emphasis lies on combining these multidisciplinary approachesâ??integrating sophisticated biomaterials, various cell-based treatments, and advanced engineering techniques. This holistic strategy aims to cultivate effective and sustained regenerative environments, thereby significantly improving functional recovery and outcomes after neural injury.
