Stem cells are very powerful and can help people with or without Duchenne’s. We all have them. When you’re sick or hurt, these cells identify and repair the damaged tissue. In a lab setting, these cells have the potential to multiply indefinitely.

In the body, adult stem cells may lose their capacity and their speed to multiply as we age. In certain people with degenerative conditions, such as Muscular Dystrophy, stem cells may not be supplied quickly enough to fully repair damaged tissue.

Types of Stem Cells


Proven to be the most effective type of adult stem cell & are found on every single blood vessel in the human body.

While there are many types of stem cells, Coming Together for a Cure is only focused on helping advance research and access to Mesenchymal stem cells. These cells are key for keeping our bodies alive; each person has an innumerable amount throughout their body. Some tissues are particularly rich in MSCs, such as bone marrow and fat, and in tissues that are discarded after a healthy birth, such as the umbilical cord, placenta, and amniotic tissue.

In short, we understand that MSCs control inflammation, modulate the immune system, stimulate regression, and decrease fibrosis and scarring. We believe the advancements of research and the proven effectiveness of MSCs will help to find a cure with many diseases.

Duchenne, the disease Ryan had, is caused by the absence of a functional protein on the mutated gene, called Dystrophin.

Dystrophin is necessary to break down and repair muscle tissue – without it the cells are unable to hold their shape causing fibrous tissue to form in the muscle and increased inflammation throughout the body and immune system.

With Ryan’s therapy, newly injected mesenchymal stem cells honed in on areas of inflammation and identified the cells in his body which lacked the Dystrophin protein. The new mesenchymal stem cells would then repair the cells negatively impacted by his disease and allow them to produce Dystrophin, allowing his body to fight back against the disease for roughly 3-4 months.

After 3 months, the newly injected stem cells would essentially become “used up” causing his improvements to plateau for a couple weeks and then eventually be overtaken by the disease once again.


During youth, the multiplication of stem cells is highly efficient. As we age, this ability to multiply naturally decreases. While in the womb, one stem cell multiplies into one billion new cells every 30 days. By the time you reach your twenties, a single stem cell will produce 32,000 cells in 30 days; at 65 years a single stem cell will only produce 200 new cells.

For those with debilitating injuries or diseases, the naturally decreasing stem cells cannot multiply fast enough to keep up with the physical deterioration. Adult stem cell therapies can help people overcome these conditions by replenishing their dying stem cells and allowing their body to fight back. Because dystrophin is necessary to protect muscle cells, without it, muscle cells are vulnerable to atrophy as there is now a higher concentration of an enzyme that destroys the muscle cells.
