What are expanded stem cells?

Louis A. Cona M.D.

A brief description of cell expansion and why it is legal to administer in the Cayman Islands.

What is stem cell expansion?

Stem cell therapy involves the implanting of stem cells into the body via IV or site injection. These stem cells can be autologous (originating from the patient's own tissue) or allogeneic (originating from an outside source, such as umbilical cord tissue), however the process is the same. What differs between these types is the amount of cells that can be extracted naturally.Samples taken from bone marrow or fat tissue can yield cell numbers in the 500,000 to 1 million range, while cord tissue can provide even higher numbers of stem cells. In the United States, it is currently considered legal to extract stem cells from sources such as these, and reintroduce them into the body as a form of treatment.

The issue becomes whether such low cell counts can have a significant impact on severe conditions, such as MS, Parkinson's, neurological damage, etc. These low-power treatments often have little impact on a patient's quality of life.

The answer to this problem is cell expansion. Cell expansion is the process of taking cells extracted from tissue, culturing them in the lab and encouraging them to reproduce. The reproduced cells are identical to the source cells, but this process allows the original few million to be grown out to over a billion cells. Treatments can then be crafted with cell numbers of 150-300 million per therapy.  This cell count provides the effectiveness necessary to see meaningful results in the body, especially in those with progressive conditions.Treatments using expanded cells are currently illegal in the US. The FDA currently does not allow cellular therapies using "manipulated" cells. The term "manipulated" refers to anything more than extracting cells from tissue samples and immediately introducing them back into the body. The process of expansion, although not changing the cells in any way besides number, is considered "manipulation". It is for this reason that many travel abroad to receive these treatments. While many cellular therapies are available in the US, few are legally able to provide effective treatment for those seeking relief.

Tyler explains his experience at DVC Stem in the Cayman Islands.

Tyler is optimistic that he will see positive results post treatment.

"The cool thing about the Cayman Islands besides being beautiful, it was an opportunity to get some rest and relaxation allowing my body to heal and restore. I'm back in the US now and feel like I am ready to conquer the world."

2 weeks post treatment, MS patient Tyler is beginning to see amazing progress. He has been wheelchair bound for the last year and has not been able to move his legs unassisted before now.


Tyler updates about his progress, explaining the amazing response he has been receiving from his friends and family.

"People coming up to me saying I am moving, talking and smiling so much better. They are noticing a lot of things that have improved over the course of 3 months."

"This morning I was able to do things that I was unable to do before, I was able to stand up and lift my leg higher than I ever have before."


5 months post treatment Tyler sends us an update on his progress.

"I'm able to smile better, I have more control over the left side of my face."

"I have an increased ability to grip, lift my legs higher and higher which has gone well."

Tyler is optimistic and on the right track to recovery. We are ecstatic to see his progress and look forward to more updates from him.

"I have an increased ability to grip, lift my legs higher and higher which has gone well."

David Lyons

Multiple Sclerosis

Although David Lyons was able to successfully fight Multiple Sclerosis through a strict regimen of diet and exercise, he wanted to ensure he was doing everything he could to stay fit. Multiple Sclerosis can be managed with treatment, but there is currently no cure for the disease. For that reason, David came to DVC Stem years ago to use the regenerative and anti-inflammatory attributes of stem cells to aid in his fight for fitness.

The positive results he experienced enabled David to stay strong in the gym, now into his 60s, and that is why he continues to support our clinic to this day.
