From Dish to Trial: Building Translational Models of ALS

Area of Science:

• Neuroscience
• Stem Cell Biology
• Genetics

Background:

• Amyotrophic lateral sclerosis (ALS) is a progressive motor neuron disease with significant challenges in modeling and treatment due to its heterogeneity.
• Induced pluripotent stem cells (iPSCs) have become crucial for understanding ALS pathogenesis and developing therapeutic strategies.
• Three-dimensional (3D) modeling systems, such as organoids and ALS-on-chip platforms, enhance the study of cell interactions and tissue-level disease phenotypes.

Purpose of the Study:

• To review advances in iPSC technology for ALS research.
• To highlight iPSC-based studies, particularly for sporadic ALS.
• To discuss iPSC-informed therapeutic strategies and associated translational challenges.

Main Methods:

• Review of iPSC technology and its application in ALS modeling.
• Analysis of key iPSC-based studies in sporadic ALS.
• Examination of emerging iPSC-informed therapeutic approaches.

Main Results:

• iPSCs have significantly advanced the understanding of ALS pathogenesis.
• 3D iPSC models better recapitulate complex cellular interactions and tissue phenotypes.
• Large iPSC cohorts, quantitative phenotyping, and patient stratification are improving translational research.

Conclusions:

• Despite challenges, iPSC technology offers a promising avenue for developing effective ALS therapies.
• Improved clinical trial design and robust iPSC models are essential for therapeutic translation.
• Continued research integrating iPSC-derived insights with clinical studies is vital for overcoming ALS.
