Intercellular Sciences Releases New Case Study on Stem Cell Treatment and its Effects on Strokes

Share Article

In one of Intercellular Sciences’ most recent patients, the effects of stem cells had an unexpected impact on their recovery from a stroke.

stem cell and heart disease.

John and Karen. John received stem cell treatment by Intercellular Sciences.

Since these stem cells are the body’s natural healing cells, some of those stem cells go to other parts of the body and start to repair damage, says Dr. Zannos G. Grekos.

Karen Anderson was hoping that her husband John, 62, would see an improvement in his damaged heart following stem cell treatment in the Dominican Republic, and he did. His heart function improved and he was able to return to how he was before his heart went bad.

What Karen didn’t expect was that his stroke would get better too. So much better that he can now drive for the first time since his stroke. “John’s response to the stem cell treatment has just been amazing, nothing short of a miracle,” Karen says. John had been struggling with severe deficits since his stroke two and a half years ago. He could not finish a sentence, do simple math, write words or even say his wife’s name correctly. Now he can carry on conversations, add up the tip on a restaurant bill and most impressively – safely drive the family car, which became very important when Karen broke her foot and John had to drive her around.

“I never thought our roles would reverse and John would be taking care of me, but thanks to his stem cell therapy he is returning back to the man he was.” Karen’s big smile says it all.

Strokes are usually blood clots that travel to the brain, block an artery and cause loss of brain function and paralysis. Stroke is a leading cause of death in the United States, killing nearly 130,000 Americans each year—that’s 1 of every 18 deaths. This is devastating to not only the patient but also to their family.

John C. (age 62, Dickson, TN), has had Cardiomyopathy (weak heart) since he was a young man. First diagnosed while in college, he has had to adjust his life style, adapting it to his weak heart function. His doctors recommended a defibrillator a few years ago and he has been dependent on it ever since. Then, in 2010, he suffered a massive stroke which left him quite disabled. His heart symptoms also rapidly worsened. Due to severe shortness of breath and fatigue, he had to stop many of his activities; even walking up his driveway had become impossible. John’s heart ejection fraction (the percent of pumping of the heart) had dropped to under 10%. His doctors were not optimistic. He and his wife Karen refused to accept such a grim fate and searched for alternative treatment. They soon found an option: adult stem cell therapy.

Zannos Grekos MD, MAAC, FACC, chief science officer of Intercellular Sciences and a Florida-based pioneer in the field of adult stem cell therapy describes how stem cells from the patient are extracted and activated in a laboratory. These cells we call Regenocytes.” Dr. Zannos G. Grekos explains how, in this groundbreaking treatment, cardiologist Doctor Hector Rosario, Chief of Interventional Therapy for Intercellular Sciences, inserts a catheter into the patient’s heart similar to a heart catheterization to inject the stem cells. The process of tissue repairing the damaged heart begins almost immediately. “Since these stem cells are the body’s natural healing cells, some of those stem cells go to other parts of the body and start to repair damage. When this happens we can see some amazing improvement in areas we hadn’t targeted. Things like arthritis or diabetes get better, even stroke symptoms like in this patient” says Grekos, who has been treating patients with stem cells since 2006.

“I have much more energy now,” said John after his treatment. “I’m back to walking the perimeter of my 6 acre property and back at cardiac rehab. I have even started bowling again which I had stopped.” An echocardiogram performed by his cardiologist 3 months after his treatment showed that his heart function had doubled.


Dr. Zannos Grekos is an Interventional Cardiologist and specialist in stem cell research and treatment. Dr. Grekos has extensive experience in the field of stem cell therapy. In collaboration with major treatment and research centers, he has developed many of the protocols used for adult stem cell therapy throughout the world. Dr. Zannos Grekos also trains physicians in the evaluation and treatment of patients receiving stem cell therapy. He was appointed to the Science Advisory Board of the United States' Repair Stem Cell Institute. Dr. Zannos Grekos was invited to Washington, DC to brief the United States Senate Health Advisory staff in 2007. Dr Grekos lectures and educates both nationally and internationally on the current clinical status of stem cell therapy.

Dr. Zannos Grekos and the Intercellular Sciences medical team continue to research the impact of adult stem cell therapy on disease. Intercellular Science specializes in heart disease treatment and lung diseases treatment as well as stem cell treatment for neurologic disease.
