Mesenchymal stem cell (MSC) therapy has emerged as a promising approach for treating Amyotrophic Lateral Sclerosis (ALS) due to its regenerative and neuroprotective properties. While research continues, several mechanisms explain the potential benefits of MSC treatment:

How MSCs Benefit ALS Patients

1. Anti-Inflammatory Action – MSCs regulate immune cell responses, reducing inflammation in the central nervous system, which is a key factor in ALS progression.
2. Neurotrophic Support – MSCs secrete growth factors like BDNF and VEGF, promoting neuron survival, growth, and neuroprotection.
3. Oxidative Stress Reduction – MSCs possess antioxidant properties that help reduce oxidative damage in motor neurons, preventing further injury.
4. Immune System Modulation – MSCs regulate immune activity by suppressing harmful immune responses and promoting protective regulatory cells, creating a favorable environment for neuron repair.
5. Paracrine Effects – MSCs release bioactive factors that enhance tissue repair, angiogenesis, and the formation of new blood vessels, improving the microenvironment for motor neuron survival.

Therapeutic Benefits Observed in ALS Studies

1. Slowing Disease Progression – MSC treatment has shown potential in delaying ALS progression by improving disease markers and motor function.
2. Extended Survival – Studies indicate that ALS patients who receive MSC therapy may experience prolonged survival compared to those who do not.
3. Improved Motor Function – MSC therapy is linked to better muscle strength, motor coordination, and functional capacity, enhancing quality of life.
4. Reduced Neuroinflammation – MSCs’ anti-inflammatory properties may help slow ALS progression by preserving motor neurons and reducing inflammation.
