CEDAR SINAI – EDITING THE TRUTH

In BUSINESS OF STEM CELLS on February 14, 2012 at 3:37 pm

I commented on the recent Cedar Sinai heart stem cell story and received an interesting response.  The Cedar Sinai story used the following erroneous quote”

“This is the first instance of therapeutic regeneration”

I took issue with this and sited the many years of trials, studies and patients treated to illustrate its inaccuracy.  See my comment below and then that of the Health Care reporter from KPCC, Stephanie O’Neill, …

…………………

Comment by StemCellBlogger, Stem cell writer, author, patient advocate.
7 long years. It has taken 7 years for the US medical system to CATCH UP to the rest of the world.

This article, though pro-adult stem cell, uses the same tired, B.S.
lines like: “This is the first instance of therapeutic regeneration”
This article blatantly ignores the thousands of of studies, trials and
patients successfully treated over the last 7 years.

Sadly, we won’t see stem cell treatments readily, commonly and
commercially available in the US for a long time. Many people will
offer comments on these developments…
The uninformed will say: “first time ever!”
The optimists will say: “better late than never”
The realists will say: “10 years before US patients will have access to these treatments”
The families of those who have died over the past 7 years will say: “if only the US woke up sooner”

Stem cell treatments are available NOW outside of the United States at
some of the most modern and advanced hospitals and clinics in the
world. Maybe, just maybe, the families of those who WILL die from heart
disease over the NEXT 10 years will say: “NOW is the time to go where
they have been treating heart disease with stem cells for over half a
decade”

Comment by Stephanie O’Neill, Health Care reporter, KPCC:
For the record: The line quoted in the comment was in neither of my stories – online or broadcast versions. Thank you, Stephanie O’Neill, Health Care reporter, KPCC.

……………………………..

WHAT THIS MEANS:

I applaud Stephanie O’Neill (not the author of the original article) for understanding that the quote, “This is the first instance of therapeutic regeneration,” is wrong and further, not wanting her article and her reporting associated with inaccurate quotes.

Reporting on stem cells is like tap dancing through a  mine field.  There is so much misinformation out there and so many conflicting agendas and interests, it is very difficult to print the truth, the whole truth and nothing but the truth.  We have a responsibility to the patients to try to disseminate the information truthfully and in a manner they can be readily understood.

Stephanie, thanks for doing your part!  You have definitely earned a gold star from The Stem Cell Blog today!

Patient's own stem cells help heal heart, early research shows

Patient’s own stem cells help heal heart, early research shows

A patient’s own heart cells can be used to regrow new heart tissue and help undo damage caused by a heart attack, according to early research published on Monday.

Scientists at Cedars-Sinai Medical Center in Los Angeles and Johns Hopkins University in Baltimore were able to treat 17 heart attack patients with cells grown from their own heart tissue and not only show the procedure was safe, but also that the cells can help reduce scarring and even cause new heart muscle to grow.

When a person suffers a heart attack, he or she is often left with huge areas of scarring in the heart. Scarred heart muscle doesn’t pump blood as well as it used to, putting stress on other parts of the heart to make up for the deficit. The damaged area also doesn’t conduct electric current as well, leading to an abnormal heart rhythm, which can cause more problems. Heart attack patients often go on to develop heart failure.

“This is the first instance of therapeutic regeneration,” says Dr. Eduardo Marbán, director of the Cedars-Sinai Heart Institute. He says while nature abounds with examples of spontaneous regeneration of limbs or tissues – like a salamander’s new tail or a human liver regrowing to full size if partially damaged – doctors have not been able to help patients regrow heart tissue. This could change in the future if larger clinical trials and longer patient outcomes confirm the results of this early research published Monday in the journal The Lancet.  Marbán and his colleagues first presented this research at an American Heart Association conference in November…

ELIZABETH TAYLOR DIES – CONGESTIVE HEART FAILURE – aged 79

Elizabeth Taylor dies of congestive heart failure!!

A devastating loss to American and World culture, film and screen and one of the most cherished and greatest characters of our time.  What strikes me as particularly troubling is that perhaps it could have been avoided.  Elizabeth Taylor suffered from congestive heart failure since 2004.  Congestive heart failure has been treated successfully outside the USA since 2004…and I’ll bet she and her loved ones (all multiple millions of them)  had no idea that there were other options out there. Adult stem cell treatments can lower a congestive heart failure patient from stage 3 or 4 to stage 1 or 2, can double Ejection Fractions and can do so in about 70% of patients.  A tragic loss. -dg

Isolation and expansion of functionally-competent cardiac progenitor cells directly from heart biopsies.

Abstract

The adult heart contains reservoirs of progenitor cells that express embryonic and stem cell-related antigens. While these antigenically-purified cells are promising candidates for autologous cell therapy, clinical application is hampered by their limited abundance and tedious isolation methods. Methods that involve an intermediate cardiosphere-forming step have proven successful and are being tested clinically, but it is unclear whether the cardiosphere step is necessary.

Accordingly, we investigated the molecular profile and functional benefit of cells that spontaneously emigrate from cardiac tissue in primary culture. Adult Wistar-Kyoto rat hearts were minced, digested and cultured as separate anatomical regions. Loosely-adherent cells that surround the plated tissue were harvested weekly for a total of five harvests. Genetic lineage tracing demonstrated that a small proportion of the direct outgrowth from cardiac samples originates from myocardial cells.

This outgrowth contains sub-populations of cells expressing embryonic (SSEA-1) and stem cell-related antigens (c-Kit, abcg2) that varied with time in culture but not with the cardiac chamber of origin. This direct outgrowth, and its expanded progeny, underwent marked in vitro angiogenic/cardiogenic differentiation and cytokine secretion (IGF-1, VGEF).

In vivo effects included long-term functional benefits as gauged by MRI following cell injection in a rat model of myocardial infarction. Outgrowth cells afforded equivalent functional benefits to cardiosphere-derived cells, which require more processing steps to manufacture. These results provide the basis for a simplified and efficient process to generate autologous cardiac progenitor cells (and mesenchymal supporting cells) to augment clinically-relevant approaches for myocardial repair.

High doses of antioxidant supplements induce stem cell genetic abnormalities

High doses of antioxidant supplements induce stem cell genetic abnormalities

May 4, 2010

High doses of antioxidant nutritional supplements, such as vitamins C and E, can increase genetic abnormalities in cells, which may predispose supplement-takers to developing cancer, according to a new study from the Cedars-Sinai Heart Institute.

The study, led by Eduardo Marbán, M.D., Ph.D., director of the Cedars-Sinai Heart Institute, was published online today in the medical journal Stem Cells. The study also will appear in the journal’s July printed edition.

Marbán and his team accidentally discovered the danger of excessive antioxidant doses while seeking a way to reduce the genetic abnormalities that occurred naturally when the scientists sought to multiply human cardiac stem cells.

Marbán stressed that the study’s finding applies only to excessive and not to foods that are rich in antioxidants, such as milk, oranges, blueberries and peanuts. In recent years, multiple studies have touted the benefits of foods rich in antioxidants.

“Taking one multivitamin daily is fine, but a lot of people take way too much because they think if a little is good, a lot must be better,” said Marbán, who is also the Mark Siegel Family Professor at Cedars-Sinai. “That is just not the case. If you are taking 10 or 100 times the amount in a daily multivitamin, you may be predisposing your cells to developing cancer, therefore doing yourself more harm than good.”

In laboratories, stem cells are often grown in a Petri dish culture than is composed of 20 percent oxygen, whereas cells growing inside human tissue are exposed to just 3 to 5 percent oxygen. But Marbán’s team of researchers became frustrated because the higher concentration of oxygen in lab-grown stem cells resulted in 9 percent of the cells being rejected because of genetic abnormalities.

“We sought to counter that oxidation problem by adding high doses of antioxidants directly to the cells,” Marbán said. “That’s when we made the serendipitous discovery that there is a danger zone for the cells exposed to antioxidants to develop genetic abnormalities that predispose to cancer.”

Marbán is leading an ongoing, groundbreaking clinical trial in which heart attack patients undergo two minimally-invasive procedures in an effort to repair and re-grow healthy muscle in a heart injured by a heart attack. First, a biopsy of each patient’s own heart tissue is used to grow specialized heart stem cells. About a month later, the multiplied are then injected back into the patient’s heart via a coronary artery.

The two-step procedure was completed on the first patient in June 2009. The results of the trial are expected in early 2011.

Recently, Marbán received a $5.5 million grant from the California Institute for Regenerative Medicine to continue developing cardiac stem cell therapies.

California’s Proposition 71 Failure

Posted 01/12/2010 06:36 PM ET

Bioethics: Five years after a budget-busting $3 billion was allocated to embryonic stem cell research, there have been no cures, no therapies and little progress. So supporters are embracing research they once opposed.

California’s Proposition 71 was intended to create a $3 billion West Coast counterpart to the National Institutes of Health, empowered to go where the NIH could not — either because of federal policy or funding restraints on biomedical research centered on human embryonic stem cells.

Supporters of the California Stem Cell Research and Cures Initiative, passed in 2004, held out hopes of imminent medical miracles that were being held up only by President Bush’s policy of not allowing federal funding of embryonic stem cell research (ESCR) beyond existing stem cell lines and which involved the destruction of embryos created for that purpose.

Five years later, ESCR has failed to deliver and backers of Prop 71 are admitting failure. The California Institute for Regenerative Medicine, the state agency created to, as some have put it, restore science to its rightful place, is diverting funds from ESCR to research that has produced actual therapies and treatments: adult stem cell research. It not only has treated real people with real results; it also does not come with the moral baggage ESCR does.

To us, this is a classic bait-and-switch, an attempt to snatch success from the jaws of failure and take credit for discoveries and advances achieved by research Prop. 71 supporters once cavalierly dismissed. We have noted how over the years that when funding was needed, the phrase “embryonic stem cells” was used. When actual progress was discussed, the word “embryonic” was dropped because ESCR never got out of the lab.

Prop 71 had a 10-year mandate and by 2008, as miracle cures looked increasingly unlikely, a director was hired for the agency with a track record of bringing discoveries from the lab to the clinic. “If we went 10 years and had no clinical treatments, it would be a failure,” says the institute’s director, Alan Trounson, a stem cell pioneer from Australia. “We need to demonstrate that we are starting a whole new medical revolution.”

The institute is attempting to do that by funding adult stem cell research. Nearly $230 million was handed out this past October to 14 research teams. Notably, only four of those projects involve embryonic stem cells.

Among the recipients, the Los Angeles Times reports, is a group from UCLA and Children’s Hospital in Los Angeles that hopes to cure patients with sickle cell disease by genetically modifying their own blood-forming stem cells to produce healthy red blood cells. Researchers at Cedars-Sinai Medical Center will use their grant to research injecting heart-attack patients with concentrated amounts of their own cardiac stem cells that naturally repair heart tissue.

Dr. Bernadine Healy, director of the National Institutes of Health under Bush 41, wrote in her U.S. News & World Report column recently that “embryonic stem cells, once thought to hold the cure for Alzheimer’s, Parkinson’s and diabetes, are obsolete.”

Even worse, they can be dangerous.

They are difficult to control, to coax into the specific type of tissue desired. Unlike adult stem cells taken from a patient’s own body, ES cells require the heavy use of immunosuppressive drugs. Their use can lead to a form of tumor called a teratoma.

.

…It is ESCR researchers who have politicized science and stood in the way of real progress. We are pleased to see California researchers beginning to put science in its rightful place.
