The Technical System, Clinical Application and Future Prospects of Pluripotent Stem Cells (ESC/iPSC) Mediated Nerve Regeneration

Abstract

This review systematically outlines the technological framework and clinical applications of neural regeneration mediated by pluripotent stem cells (ESCs/iPSCs). The article first compares the fundamental differences between the two: ESCs face ethical controversies regarding their embryonic origin and challenges related to immune rejection; while iPSCs support autologous transplantation, their reprogramming process may lead to genomic abnormalities, and the presence of residual undifferentiated cells poses a tumorigenic risk. The article traces the trend of directed differentiation technologies evolving from two-dimensional culture to three-dimensional organoids and details their practical applications in diseases such as stroke, Alzheimer's disease, and spinal cord injury—particularly in spinal cord injury models, where transplanted cells have achieved long-distance axonal regeneration and circuit reconstruction. Addressing core bottlenecks currently facing the field—such as low differentiation efficiency, difficulties in functional integration, and tumorigenicity—this paper explores breakthrough pathways through cutting-edge technologies including gene editing, organoids, and AI-enabled approaches. Finally, it compares the clinical advantages and disadvantages of ESCs and iPSCs, noting that while challenges remain, the deep integration of interdisciplinary technologies is accelerating the translation of stem cell therapies into standard clinical treatments, bringing revolutionary hope to patients with neurological diseases.

Environmental Risk Assessment and Confinement of Genetically Engineered Trees with an Emphasis on Vegetative Reproduction.

Genetic engineering (GE) and gene editing may endow traits to trees such as increased biomass and the production of novel biomaterials. Long-lived organisms such as trees might be subject to biotechnology-related risks that could be different than those of annual row crops. Those risks could be relevant to production in engineered plantations and beyond plantations to natural forests. Therefore, appropriate risk regulation is important to assure biosafety of commercialized engineered trees. In addition to gene flow via sexual reproduction, vegetative reproduction might play an additional role in environmental "exposure" risk relative to transgene dispersal in GE tree plantations. While vegetative reproduction is beneficial for preserving desired genetic traits during tree propagation, it may lead to proximal clonal spread in the field. Although the environmental risks associated with vegetative reproduction of GE trees are recognized in commercial forestry, there are few field-based environmental risk assessment (ERA) studies on dispersal risks of self-propagated GE trees. GE or gene editing of target genes involved in the vegetative propagation processes may be useful to mitigate environmental risks of clonal spread through vegetative reproduction. This review provides updates for recent field test results of GE and gene edited trees. Gene candidates related to vegetative reproduction including adventitious shooting (AS) and adventitious rooting (AR) are discussed herein as a means to mitigate unintended clonal spread from GE tree plantations.
