Embryonic and cord tissue-derived stem cells

Explaining the difference between embryonic and cord tissue-derived stem cells.

Stem cells have been studied for decades, but the methods that were used caused much controversy in politics and religion. In the early years, stem cells were sourced from human embryos, which required the destruction of the embryo. This was quick to cause widespread ethical disputes and concerns over whether stem cell medicine should be pursued. However, in recent years, other stem cell sources have emerged that are less harmful. For instance, stem cells can now be sourced from fat tissue, bone marrow, and umbilical cord tissue after birth, at no harm to the baby. Even with these advancements, the stem cell field has struggled to shake its controversial reputation.

Embryonic Stem Cells

Stem cells are undeveloped cells that have not yet been specialized in the body. They have the potential to become many different types of cells in the body. This is how embryos develop from a group of cells, into a fully grown human with functioning organs. Early researchers discovered that these stem cells could be sourced from embryos and used for studies and the creation of treatments. These powerful cells could be used to grow new tissue as they were designed to do, such as organs, bones, and more. It was also possible to use these cells to clone humans and animals. However, as previously mentioned, this introduced a number of questions on their ethical uses, and many were opposed to the practice. This quickly led to legislation in the United States, banning many treatments with the use of stem cells.

Embryonic stem cells are still used today, but new techniques have been developed to extract the cells without harming the embryo. While still remaining controversial, this practice has largely been relegated to specialized research projects, and not for the production of standard stem cell therapies found today. DVC Stem does NOT use embryonic stem cells.


With more recent discoveries in stem cell medicine, researchers began to uncover other sources for stem cells. These sources, such as cord tissue, bone marrow, and fat tissue, provided similar strength stem cells and were completely nondestructive or morally questionable. By sourcing stem cells from these alternatives, researchers could still use the cells to form new therapies, but the practice would be much more ethically sound. Additionally, stem cells from these sources cannot be used for cloning, which was another moral hurdle overcome.

The most effective source and the source we use for our stem cell therapies is donated umbilical cord tissue. After childbirth, the umbilical cord is often discarded as medical waste. However, studies have discovered that there is a large number of highly potent mesenchymal stem cells within the cord tissue. This has led to a booming industry of stem cell banks that offer parents the ability to extract and store their cord tissue cells for potential use at a later date. Additionally, parents are given the option to simply donate their cord tissue to companies that source them out to stem cell laboratories for expansion. This is how our partner laboratory, Vitro Biopharma, acquires their stem cells. With this practice, we are able to offer highly effective stem cell therapies, without causing any harm to anyone.

DVC Stem

DVC Stem is a stem cell therapy pioneer, offering stem cell therapies for years and has become a cornerstone of the medical tourism industry. Located in the tropical paradise of Grand Cayman in the Western Caribbean, we offer patients a nearby alternative to traveling long distances and to less ideal locations. Our protocols are IRB approved, and our cells come from regulated, U.S. based, FDA compliant laboratories. We seek to offer the highest quality products, the latest available treatments for a variety of conditions, all combined with a world-class setting and service.


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.

"I'm on a path of progression and I'm getting better and better each day."

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."

"This is exciting stuff, god bless"

Matthew Murry - MS Patient


Matthew experiences sensation in the bottom of his feet after receiving a simple nerve test.

His left foot did not experience any sensation or move at all, but what happened to his right foot is extremely exciting!

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.
