Abstract

Due to the intrinsically low turnover of neural tissues, regenerative therapies have gained significant interest in the context of degenerative diseases and injury to the central and peripheral nervous systems. Although a range of neuroregenerative strategies involving cell transplants and drugs have been explored, these are often limited by low efficacy and unwanted side effects. Electrical stimulation (ES) is thought to modulate the proliferation and differentiation of neural stem cells (NSCs), and thus it represents a promising strategy for neuroregenerative therapies. However, its influence on the biology of endogenous and exogenous NSCs, and the effect of different stimulation paradigms remains unexplored. Additionally, the variability of stimulation platforms and parameters employed in previous studies prevents reliable and reproducible discoveries. Therefore, there is a need to develop versatile and robust tools to study the effect of electrical stimulation on NSC fate in vitro. This paper outlines the development and functional application of a standardised, electrically stable, and easily reproducible ES platform for in vitro neuroregeneration applications.Clinical Relevance- The elucidation of the cellular and molecular mechanisms underlying the effect of ES paradigms on NSCs proliferation and differentiation holds great potential for the development of neuroregenerative therapies.
