Clinical Study of Induced Pluripotent Stem Cells Derived Motor Neuron Precursor Cell Therapy for Amyotrophic Lateral Sclerosis (ALS)

Amyotrophic lateral sclerosis (ALS) is a severe neurodegenerative disease in the human motor system characterized by the selective involvement of spinal cord anterior horn cells, brainstem motor nuclei, and the corticospinal tract. It predominantly presents as concurrent damage to upper and lower motor neurons. Induced pluripotent stem cells (iPSCs) are a type of induced pluripotent stem cell derived from autologous or allogeneic cell sources. They can differentiate into various functional cell types, including specific motor neuron cells. iPSCs are used for stem cell replacement therapy. iPSCs hold significant clinical potential for ALS treatment. The iPSC database with human leukocyte antigen characteristics may represent a promising technology. This technology has the potential to obtain high-quality cell products and reduce the risk of graft rejection. Moreover, human iPSCs have demonstrated a certain degree of efficacy in the transplantation of neural stem/progenitor cells derived from ALS rodent models. The potential mechanisms of iPSC therapy for ALS include: the differentiated motor neuron precursor cells can replace damaged motor neurons, and restore motor conduction function; by secreting neurotrophic factors, they protect neurons; through immune regulation, they inhibit inflammatory reactions, and slow the progression of ALS. Xellsmart Biomedical (Suzhou) Co., Ltd. is developing an injectable solution for ALS treatment using human iPSC-derived motor neuron precursor cells to address the pressing need for ALS therapy.
