Investigating nanoparticle's utilization in stem cell therapy for neurological disorders.

Abstract

Stem cell therapy is a promising area of regenerative medicine, offering potential treatments for various life-threatening disorders. Stem cells are classified based on their differentiation potential into totipotent, pluripotent, and multipotent stem cells. Among them, mesenchymal stem cells (MSCs) are widely used in regenerative medicine due to their tissue regeneration capabilities and ability to differentiate into multiple cell types. Stem cells are being explored for treating neurodegenerative disorders like Parkinson's, Alzheimer's, Huntington's, and amyotrophic lateral sclerosis (ALS). These conditions result from progressive neuronal degeneration, leading to irreversible damage. Challenges such as cell survival, immune rejection, tumor formation, and ethical concerns related to embryonic stem cells need to be addressed. Nanotechnology is emerging as a tool for enhancing stem cell therapy, improving targeted delivery and effectiveness. Nanoparticles possess the ability to create microenvironments as substrates, facilitate targeted administration, and enable real-time, precise imaging of stem cells. This review explores the integration of stem cells and nanotechnology as regenerative medicine tool for neurodegenerative disease treatment, analyzing current strategies and therapeutic approaches. Integrating nanotechnology with stem cell therapy may significantly improve targeted delivery and enhance regenerative outcomes for neurodegenerative disorders.
