Busting 4 Myths About Stem Cell Research

Scientist in lab

Remember stem cell research? In the mid-2000s, it became one of the biggest hot-button topics in medical research.

The debate has grown quieter since then. But don’t mistake silence for a lack of activity. Stem cell research is alive, well and as full of possibilities as ever.

Below are a few common myths about this research — and the facts that debunk them.

Myth 1: Stem cell research is illegal

Not so. In fact, stem cell research — including hotly debated embryonic stem cell research — is legal and flourishing in the United States.

The National Institutes of Health funded nearly $1.3 billion worth of stem cell research in 2013. And the state of Ohio has contributed more than $25 million to the National Center for Stem Cell and Regenerative Medicine, a collaboration among Cleveland Clinic, Case Western Reserve University, University Hospitals Case Medical Center, Athersys Inc., and The Ohio State University. It’s the fifth-largest stem cell research institute in the country.

Myth 2: All stem cells are the same

When you hear “stem cells,” you probably think of embryonic stem cells. But a lot of research focuses on other types.

Embryonic stem cells are powerful because they are pluripotent. They can develop into any type of cell in your body. But they’re often controversial because of their origin.

In contrast, almost every organ in your body has its own “adult” stem cells. These cells help grow and maintain your body’s organs as you age. They can’t develop into as many cell types as embryonic stem cells, but they are still promising for patient treatment.

The “tool box” is growing, too. Researchers have successfully used umbilical cord stem cells — taken from a newborn’s cord blood — to treat leukemia and other blood disorders. In 2012, researchers transformed them into other types of cells for the first time. This breakthrough could open the door to treating multiple diseases.

Induced pluripotent stem cells (iPS) show promise, too. These adult cells are genetically reprogrammed to act like embryonic stem cells. Researchers create them directly from a patient’s cells, so they provide an exact genetic match. In the future, iPS cells could provide therapy for everything from Parkinson’s to cardiovascular disease. There’s a hurdle to clear first, though. iPS cells sometimes become cancer cells — making them too dangerous for patient therapy now.

Myth 3: Adult stem cells are better than embryonic stem cells

In truth, researchers invest time and hope in embryonic stem cells for a reason: flexibility. With the right techniques, doctors can direct them to become virtually any type of cell needed for treatment.

For example, Jan Jensen, PhD, of the Lerner Research Institute has created insulin-producing pancreatic cells in the lab. Now, he is working with Beta02 Technologies to move his research forward. If successful, his work would offer not only a treatment but also a cure for type 1 diabetes.

Adult stem cells are powerful, but they come with more drawbacks. They age with you, so they may accumulate genetic mutations from the environment or the natural aging process.  In addition, adult stem cells can trigger a strong immune response that causes people to reject transplants without drugs to suppress the immune system. Embryonic cells don’t come with that concern.

Myth 4: Stem cells only help patients with Parkinson’s or spinal cord injuries

Research has moved far beyond a handful of diseases. Dr. Jensen’s work on type 1 diabetes is a good example, and other work is even further along.

Cleveland Clinic’s Jeff Cohen, MD, is leading a study that uses stem cells purified from bone marrow to treat patients with multiple sclerosis. And the Multistem system, developed by Cleveland-based Athersys Inc., makes adult stem cells more viable for treating diseases. The product is currently in clinical trials to treat stroke patients.

The list goes on. Stem cells could one day heal ailing hearts, repair damaged muscles, reduce inflammatory bowel disease symptoms and improve transplant outcomes. Researchers are also looking in unexpected places for stem cells — such as discarded hip joints after replacement surgery and in fat cells removed after liposuction.

The stream of discoveries has turned into a river that is rushing toward the clinic.

    Oh dear Lord, my daughter is 30 years young, has 3 small children, her husband is active duty military and is gone around 7 months out of a year on a submarine. She was just diagnosed with this in 2014. She has lived in extreme pain due to serious spine problems and the ordeal she has been through with that alone is horrific!! I can’t loose my baby girl, please tell me this is not going to take her life! She is on 3 different kinds of blood medicine with one being an emergency prescription that she has to take regularly because her BP is always very high even being on all this medication.

      jmama – we would love to see your daughter at the Cleveland Clinic for an evaluation – but if she is unable to travel – I would suggest a second opinion in a large heart center that treats many patients with this condition. You may also be interested in web chats we do with our physicians – you can ask them questions – you can see a calendar of events at http://chat.clevelandclinic.org/ Your daughter can also talk to our nurses at http://www.clevelandclinic.org/heartnurse Hope this helps – betsyRN

      Whole foods plant based no oil could work for her–Eat to Live by Dr Joel Fuhrman is worth checking out.

    Thank you for discussing this great topic. I have had a high sed rate for the last 3 years, no doctor has been able to tell me why… all other test such as rhumatoid factor, etc are normal. The Sed rate is between 50 – 78 (that’s in the last 3 years).
    I’m telling them that I’m not feeling my normal self, no doctor listens.
    I am 43 F… no blood pressure, no diabetes, thyroid normal.
    Please advise, what should I do?

      Do you have a virus? Viruses will cause ESR to run high. Thick blood will too. Dehydration can contribute.

      • Looking for diagnosis

        None of that.

          There are viruses we have no test for …
          Unfortunately conventional medicine does not have all the answers. Lifestyle modification, in the meantime, can help buffer your body from the effects of inflammation.

      I have had high sed rate and crp for almost 5 years. My sed at the higest was 114, crp is also elevated. I went to Clev Clinic had every blood test known, exploratory surgery, bone marrow biosopsies. Cat scans Mri , pet scans. I have lost approx. 15-20 lbs, little appetite. Have taken Kineret and Aleve daily, Illaris also. Very tired and hight fevers. All the Drs can tell me is I have an inflammation. RA test are negative. There just are no answers.
