A University of Bristol team extracted stem cells from the veins, then used them to stimulate new blood vessel growth in mice, Circulation reports.

The researchers say their findings could bring treatments to repair damaged heart muscle one step closer.

However, a stem cell expert warned that they remained some years away.

Stem cells are attractive to medical researchers because they have the ability to produce many different types of human cell, opening up the possibility of repair or renewal for tissues ravaged by disease or injury (…)

The song “Take another little piece of my heart” by Janis Joplin has new meaning today as doctors in Los Angeles have taken Adult Stem Cells directly from a heart attack patient’s heart and used those stem cells to treat the patient in an adult stem cell research study.

As part of a Phase 1 clinical research study, Dr. Eduardo Marban, of Ceders Sinai Hospital, did a minimally invasive biopsy and took a piece of Kenneth Milles heart muscle after Kenneth had suffered a heart attack.

The piece of his heart was sent to a lab where the Adult Stem Cells were cultivated to produce millions of Kenneth’s heart stem cells. 4 weeks later, the stem cells were implanted back into Kenneth’s heart muscle. The goal to help regenerate the damaged heart tissue from the heart attack.

From the stem cell article:

“We seek to actually reverse the injury that has been caused by the heart attack, by re-growing new heart muscle to at least partially replace the scar that’s formed,” says Dr. Eduardo Marban of Cedars-Sinai Heart Institute.

Doctors are using stem cells, the body’s master cells, because they can transform into different kinds of tissue.

Marban says, “These cells that we’re putting in come from the heart itself, and are predestined to generate heart muscle and blood vessels.”

Other types of stem cells, like bone marrow, have been studied for heart repair, but with mixed results. Animal studies indicate heart stem cells do a better job. The problem is: the heart has so few stem cells that researchers have to grow more.

And they did grow more- doesn’t seem like that big a problem.   Hopefully the money for this problem came from the California taxpayers- at least that would be the first positive that ever came out of their stem cell funding- using heart stem cells to help people.  However, the cynic in me says that is not the case.  I’m guessing it was privately funded.

Kenneth was the first patient treated with this method and the results are not in yet.  However, why wouldn’t it work? The patient’s own Adult Stem Cells are used.  The patient has nothing to lose.

In a bold move that is sure to shake the foundations of the United States FDA, a group of American doctors have published a set of strict clinical guidelines that will allow US doctors to treat patients with their own Adult Stem Cells.

Your Own Stem Cells Are Not a Drug

This move by the American Stem Cell Therapy Association comes in response to the FDA’s position that a person’s own stem cells should be classified as a drug, thus subject to the exact same set of standards that a drug like Viagra or Lipitor or Vioxx would be examined under.

However, these US doctors are correct in believing that adult stem cell therapy with the patient’s own cells is governed under the practice of medicine, not under drug production guidelines.

From the stem cell press release:

Adult stem cells can be processed with the same techniques commonly used in existing in-vitro fertilization (IVF) labs. “Like the human cells and tissue used in IVF, adult stem cells are not drugs,” stated Christopher J. Centeno, M.D., a physician who worked on the guidelines and whose medical practice includes the use of the Regenexx procedure, which uses patients own stem cells to treat orthopedic conditions.

Slowing Progress, Costing Lives- the US FDA at Work

“Making the stem cells in your own body a drug won’t make them safer, will dramatically reduce availability of treatment, and will increase bureaucratic red tape.” stated Dr. Centeno.

Dr. Centeno is absolutely right.  These are your own cells and having the FDA regulate your own body won’t be helping anybody as there is no downside to having your own stem cells implanted.

Let me repeat that- there is no downside to having your own Adult Stem Cells implanted. Either they will help you or they won’t (no effect).  This has been proven in thousands of studies.

Your own stem cells should be an extra tool your doctor should be able to use to help you.  No, adult stem cells are not a cure yet, but they do help in the majority of cases.

Again, your own stem cells should be a tool in your responsible doctor’s tool kit that may or may not be able to help, but should be made available to you as there is no downside.  What does the patient have to lose?  A man in end stage heart failure about to die- give him his own stem cells, they should help. He may not be beating Husain Bolt in a 100 meter sprint, but should improve.  A spinal cord injury victim, give him his own stem cells, they should help.  He/she may not be walking, but it could be beneficial in some ways.  A diabetic, give him his own stem cells- they should improve his insulin levels. And if your own stem cells don’t help- there is no harm done- thousands of studies have proven this.

And what if your own Adult Stem Cells work only 5% of the time for a particular lethal disease and your doctor wants to try to save your life? Hey! It will save 5% more than zero. With no downside, why not? And if the FDA has its way, that 5% will be 0. It is up to all of us to make a stand. And these clinical guidelines are the first step.

If you are a patient of any kind and reading this, I urge you to go to Safe Stem Cells Now, a patient run organization demanding the use of their own stem cells.

Dr. Amit Patel of the University of Utah is reporting that 3 out of 3 heart disease patients have improved in the initial stages of his stem cell research trial in which the cardiomyopathy patients had their own Adult Stem Cells injected back into their heart in a minimally invasive surgical procedure.

Dr. Patel presented the initial data at the International Society for Cellular Therapy (ISCT) annual meeting in San Diego, California.  The clinical research trial is treating heart patients with both ischemic cardiomyopathy and non-ischemic dilated cardiomyopathy and then injecting them with their own Adult Stem Cells.  There is a control group in the study as well. Translation-  some patients are not getting the benefit of the stem cells and receive a placebo.

Initial Data of Patients Treated with Adult Stem Cells

Here are the results so far (from the stem cell article)-

• 3 cardiomyopathy patients who received their own stem cells were followed up at 3 months.  They all improved on their New York Heart Failure Classes- all 3 going from a Class III to a Class II.  In contrast 2 out of the 3 who didn’t get stem cells , did NOT improve.
• Overall quality of life scores (Minnesota Living with Heart Failure Questionnaire) improved in all 3 patients who received the stem cell therapy.  The physical and emotional well-being of all the patients who received the treatment also improved.  There was no consistent trend in the control group (the group that didn’t get the stem cells)

Millions Would Benefit With Use of Own Stem Cells

While these are positive results and I am happy for these patients, there are thousands of cardiomyopathy patients who are not able to receive this stem cell treatment.  Dr. Kit Arom of Vescell in Thailand, a former associate of Dr. Patel, is now treating these exact same patients with their own stem cells and none of these dilated cardiomyopathy and heart attack patients are in a “control” group ie. they are getting the exact same procedure and getting their own Adult Stem Cells that Dr. Patel’s trial is doing (sucessfully).

Dr. Kit Arom has been treating heart disease patients in Thailand since 2005 with this exact same procedure- and the USA has just done 3??? Is something wrong here?

The Debate on Stem Cell Research – A Smokescreen?

While there is the endless debate on Embryonic Stem Cell research vs. Adult Stem Cell research, is the debate just some  clever smokescreen thrown up by the drug companies, FDA, and cardiologists, none of whom will benefit from heart (or name your disease)  patients using their own Adult Stem Cells to help themselves?  Is this stem cell debate just a means to slow down the use of the patient’s own cells?  Remember, there are no side effects from using your own stem cells, either they help (most of the time) or they don’t (no harm done).

Are people getting so caught up on the stem cell research issue that we are ignoring the patients who are in need of help right now?  Are we so intent on 100% “cures” that we ignore stem cell treatments that are not “cures”, but do indeed help improve the quality of lives of the majority of patients right NOW.   I’m sure the patients who improved in the stem cell heart study above are very happy with their results.  Are their hearts 100% perfect now?  No,  it wasn’t a “cure”.  Does that mean it isn’t good enough?

Why do we have to go for the homerun on every at bat, when a patient would be grateful for a single or double?  Would Michael J Fox be happy if his Parkinson’s symptoms subsided for 5 years like this gentleman?  Or, I’m sure the heart patients are pleased that instead of getting short of breath from getting the mail, that they are probably now able to walk around their local mall with their loved ones.

I see endless articles and letters to the editor that support this research or that research, but rarely do I see an article or letter promoting USING the only treatment that works now- Adult Stem Cells.  In the end, with all this hoopla, we end up forgetting about what should be the reasons for the debates and research in the first place- the patients.

For patients who suffer a major heart attack, get treatment at the hospital but are left with a damaged heart, Dr. Roger Gammon of the Heart Hospital of Austin is testing a new process to reverse that damage.

Just as a Houston hospital is investigating stem cells to repair the brains of stroke patients (see yesterday’s blog), the Heart Hospital is trying out a new stem cell therapy to fix the hearts of patients who suffered their first attack.
It is one of the nation’s first hospitals to test the new therapy.

Gammon, an interventional cardiologist, is leading the clinical trial in which patients are injected with donated adult stem cells from the bone marrow of others. The stems cells are purified by Osiris Therapeutics, Inc., which markets them as a product called Prochymal. Osiris is financing the research project, which is being done in the gold-standard way: Half of the patients are getting stem cells, and half are getting a placebo (a harmless product that looks the same). The researchers and patients don’t know which patients are getting the stem cells and which one aren’t.

Not all stem cells are ‘good’ at aiding the heart in repairing itself after a heart attack. Apparently, ‘baby cells’ present in human fat are the best equipped to perform this task and could be used in human testing by the end of 2009. “ We have seen that a simple stem cell transplant into a heart after a heart-attack is not sufficient. There are different types of stem cells that are better adapted to aiding the heart in the healing process. Instead of hematopoietic stem cells used in initial studies, mesenchymal stem cells are now being used.
