Although ALS has historically been characterized as a motor neuron disease, there is evidence that motor neurons degenerate in a retrograde manner, beginning in the periphery at the neuromuscular junctions (NMJs) and skeletal muscle.

The myotendinous junction (MTJ) is an integrated structure that transduces force across the muscle-tendon boundary, making the region vulnerable to strain injury.

Amyotrophic lateral sclerosis (ALS) is a fatal neuromuscular disease in which patients gradually become paralyzed due to loss of motor function. Many genetically inheritable mutations have been linked to ALS; however, the majority of ALS patients are considered sporadic.

Amyotrophic lateral sclerosis (ALS) is a late-onset neuromuscular disease with no cure and limited treatment options. Patients experience a gradual paralysis leading to death from respiratory complications on average only 2-5 years after diagnosis.

Human induced-pluripotent stem cells are a promising resource for propagation of myogenic progenitors. Our group recently reported a unique protocol for the derivation of myogenic progenitors directly (without genetic modification) from human pluripotent cells using free-floating spherical culture.

Our current research is to apply stem cell technology to disease modeling and therapeutic applications for neuromuscular diseases such as ALS (also known as Lou Gehrig’s disease).

Engineered stem cells carry promising ALS therapy
“The novelty is that this is a combined cell and gene therapy approach,” Suzuki explains, noting that the bone marrow stem cells on their own had a modest effect, possibly by releasing their own protective factors. “But only when we engineered the cells to release GDNF did we see a significant improvement. The cells turned out to be quite an important component. It’s this combination of cells and drug delivery that seems to be so effective.”
DHEA Boosts Growth Rate Of Human Neural Stem Cells
Human neural stem cells, exposed in a lab dish to the steroid DHEA, exhibit a remarkable uptick in growth rates, suggesting that the hormone may play a role in helping the brain produce new cells.
