A scoping review of stem cell models of leukodystrophies: advances in understanding pathophysiological mechanisms

Leukodystrophies are a diverse group of genetic disorders affecting the central nervous system white matter. Since their initial identification over a century ago, significant advancements have been made in understanding their genetic and clinical profiles. Yet, disease modifying therapies are limited, despite significant clinical impact characterized by progressive neurological decline leading to severe disability and early mortality. This underscores the need for advanced disease models to facilitate the understanding of disease mechanisms and the development of early therapeutic interventions. Stem cells have emerged as a transformative tool in leukodystrophy research, enabling the generation of patient-specific cells otherwise inaccessible for study. We have conducted the first scoping review of stem cell-based disease modeling in leukodystrophies, highlighting recent developments, challenges, and future directions in leveraging these models to enhance our understanding and aid in the development of therapies for these debilitating disorders.
