Umbilical Cord
Blood & Cord Blood Stem Cell
Therapy: Is Something Amiss? By Anthony
G. Payne, Ph.D.
One of the
most frequent complaints I hear when chatting with folks about the promise and
limitations of umbilical cord stem cells in addressing various non-blood borne
human maladies is the seeming intransigence of “the feds” (NIH and FDA) when it
comes to allowing doctors to employ these cells in hospitals and medical offices
here in the United States. Many
resent the fact they must travel to Mexico, Thailand, Holland and other
countries to get what they perceive is a fundamentally safe though admittedly
experimental treatment for conditions such as chronic stroke, cerebral palsy,
ALS, multiple sclerosis, macular degeneration and a host of other human
afflictions.
The FDA, as we all know, has a mandate to make sure that the
pharmaceuticals, surgical techniques, medical devices and biologic agents and
vaccines that reach the medical consumer are safe and effective. In this regard they have had a great
deal of success and their fair share of failures such as the fenfluramine-dexfenfluramine
(Fen-Phen) Celebrex® and Vioxx® drug
scandals. And their ranks are certainly not immune to corporate influence and
even corruption, as we all learned when it was revealed that a great many
researchers at the NIH were being paid handsome consultancy fees from major
pharmaceutical companies.
Reform is
obviously needed and is in fact underway. Senior NIH officials are no longer
allowed to take consultancy fees from private firms and limitations were imposed
on regular staff as well. But is this enough? Many of the people I speak with
feel that something is amiss at the NIH and FDA, and they point to cord blood
itself as a prime example. Yes, these are typically individuals who have a stake
in being able to have cord blood or cord blood stem cell treatments done on
themselves or a relative or friend. But even so, these folks are not blind or
stupid; they have more-often-than-not done their homework in terms of scouring
and analyzing the scientific literature and a great many report seeing a
disturbing pattern: In-a-word, they see the guardian of public health -- the FDA
-- seemingly intent on standing in the way of progress. They also detect a kind
of tunnel vision within the scientific community as well. Is this perception
merely a species of “conspiratorial thinking” or post 9-11 paranoia? Or is there
indeed something amiss going on? And if there is something amiss, what should be
done about it? The use of
cord blood in the American medicine goes back at least 20 years. Scientists
found that the stem cells in cord blood could be used to create a whole new bone
marrow system in people whose own marrow was defective in some way. For example,
in many folks with leukemia it was found that eradicating the patient’s bone
marrow with chemotherapy or radiation, then infusing cord blood often led to the
genesis of healthy, cancer free marrow. Other blood borne and some immune system
applications followed. Today no credible expert disputes the therapeutic power
cord blood stem cells hold when it comes of addressing diseases and disorders
that arise because of some defect in bone marrow function. Recently, advanced
multiple sclerosis patients have the option of having their bone marrow replaced
in a fashion not unlike that of leukemia victims. As this is highly
experimental, patients must cough up $100,000 or more the many centers that do
this procedure typically charge. As MS is, at least in part, an autoimmune
disease in which immune cells generated in bone marrow attack the myelin sheath
that insulate nerves in the patient’s central nervous system, it makes sense
that this approach might work. And there are patients on record so treated whose
progressive MS is now in remission. This body of
clinical application and the research underlying it leaves little doubt but that
cord blood and cord blood stem cells have imminent utility in ameliorating and
in some instances curing some bone marrow-spawned or related diseases and
disorders plus various immune system-related disorders. But what of non-blood
borne diseases and disorders? According to
many mainstream researchers and stem cell experts, cord blood and cord blood
stem cells will have little if any salutary effect in neurologic, eye,
circulatory and other conditions. Since embryonic stem cells do have
demonstrated plasticity, which is to say the ability to form the multitude of
tissues and such that make up the human body, this has become the focus of much
stem cell related research and state, federal and private funding here in the
States. But in the rush to lay hold of the promise inherent in embryonic stem
cells have many mainstream scientists and the NIH and FDA prematurely written
off the potential for cord blood and cord blood stem cells to significantly
improve or in some instances turnaround many non-blood borne conditions? Have
one or more of these players intentionally or unintentionally placed bias above
scientific curiosity and openness? Many scientists and a great many laypeople
think so. ____________________________________ Excerpted
section from a government sponsored paper -- What one scientist says about
umbilical cord stem cells: David
A. Prentice, Ph.D.
Use
of umbilical cord stem cells has seen increasing interest, as the cells have
been recognized as a useful source for hematopoietic transplants similar to bone
marrow stem cell transplants, including for treatment of sickle cell
anemia.164 Cord blood shows
decreased graft-versus-host reaction compared to bone marrow,165 perhaps due to high
interleukin-10 levels produced by the cells.166 Another
possibility for the decreased rejection seen with cord blood stem cell
transplants is decreased expression of the beta-2-microglobulin on human cord
blood stem cells.167 Cord blood can be
cryopreserved for over 15 years and retain significant
functional potency.168 Cord blood
stem cells also show similarities with bone marrow stem cells in terms of their
potential to differentiate into other tissue types. Human cord blood stem
cells have shown expression of neural markers in vitro,169 and intravenous
administration of cord blood to animal models of stroke has produced functional
recovery in the animals.89,170 Infusion of
human cord blood stem cells has also produced therapeutic benefit in rats with
spinal cord injury,171 and in a mouse
model of ALS.172 A recent report
noted establishment of a neural stem/progenitor cell line derived from human
cord blood that has been maintained in culture over two years without loss of
differentiation ability.173 Several
reports also note the production of functional liver cells from human cord blood
stem cells.174 Additional
differentiative properties of human umbilical cord
blood stem cells are likely to be discovered as more investigation proceeds on
this source of stem cells. From

What is known about adult stem cell differentiation? Adult
stem cell plasticity and transdifferentiation.
A number of experiments have suggested that certain adult stem cell types are
pluripotent. This
ability to differentiate into multiple cell types is called plasticity or transdifferentiation. The following list offers examples of
adult stem cell plasticity that have been reported during the past few
years. •
Hematopoietic
stem cells may differentiate into: three major types of brain cells (neurons,
oligodendrocytes, and astrocytes); skeletal muscle cells; cardiac muscle cells;
and liver cells. •
Bone
marrow stromal cells may differentiate into: cardiac
muscle cells and skeletal muscle cells. •
Brain
stem cells may differentiate into: blood cells and skeletal muscle cells.
Current
research is aimed at determining the mechanisms that underlie adult stem cell
plasticity. If such mechanisms can be identified and controlled, existing stem
cells from a healthy tissue might be induced to repopulate and repair a diseased
tissue http://stemcells.nih.gov/info/basics/basics4.asp
____________________________________ This
sounds all fine and good. On the one hand we have Dr. Prentice’s statement that
cord blood and cord blood stem cells has improved stroke, spinal cord injury and
ALS in animal models. On the other, we see that adult stem cells including
hematopoietic (bone marrow and cord blood) progenitor/stem cells can be
transformed into non-blood and immune related cells such as neurons, cardiac
muscle and liver cells CORD BLOOD STEM CELL
PLASTICITY,
although admittedly we need to understand more about the mechanisms that bring
this about so that we can control it and target repair in the human body.
But
what of the merit, if any, of cord blood or cord blood stem cells that are
simply infused, injected or implanted in people? That is, put in without being
primed or differentiated outside (ex
vivo) the recipient’s body? Shouldn’t we expect salutary effects in at least
some non-blood borne conditions given what has been seen in rats and other lab
animals? Doesn’t it make sense that if these cells can be given to an animal –
not provoke rejection or any appreciable adverse reaction – and bring about
repairs in brains ravaged by induced strokes or spinal cord injury or ALS --
that this scenario might hold true in humans also? Well,
this is exactly what researchers at Steenblock Research Institute have been
documenting since early 2003.* While their evidence to-date is tentative and far
from qualifying as rigorous in the hard science sense, they feel there are
sufficient specific repetitive post-stem cell treatment improvements in various
medical conditions to warrant pursuing formal randomized clinical trials. For
example: Three
(3) children with cortical blindness due to optic nerve atrophy or hypoplasia experienced partial resolution of this within 90
days following a single infusion of 1.5 million CD34+/CD133 umbilical cord stem
cells (in One
of these children, Adam Susser, was not only
cortically blind prior to hUCSC therapy, but could not
get about well or speak either. Four stem cell treatments later he is doing all
three. Adam’s father, consumer affairs attorney Gary Susser, has set up the ADAM SUSSER FOUNDATION devoted to
helping children like his son. A
5 minute Sinclair Broadcast Group video on Adam can be readily access online by
going to STEM CELL THERAPIES.ORG Click the
“Resources” link – drop down to #12 – and click the “Watch Stem Cell Video
Link”. Also: At
least 5 children with intractable seizures are reported to have experienced a
significant reduction in frequency and intensity following hUCSCT (Injected and IV). Many became seizure free within
months following their treatment. Many
adults with visual impairment due to stroke or macular degeneration have
experienced partial recovery of their ability to see following catheter
infusions of various kinds of cord blood derived stem cells, e.g., CD34+/CD133,
mesenchymals, CD34-/45+, primitive neurogenic progenitors, etc. During 2004
SRI took part in a pilot study conducted by Fernando Ramirez, MD in

addition, some of the children who participated in this study have had their
stories showcased in “Umbilical

Stem
Cell Therapy”
(Basic Health Publications, 2006) by David A. Steenblock, M.S., D.O. & Anthony G. Payne, Ph.D. This
book is probably the first book on cord blood stem cell therapy ever written for
laypeople. Similar
case histories are being reported by clinics and hospitals that do cord blood
stem cell therapy in Even
cord blood itself has shown efficacy in ameliorating some non-blood born
disorders. One example is a body of
separate lab experiments carried out by Dr. Normal Ende ( And

The
Response of the NIH, Federal Regulatory Agencies & Mainstream
Researchers
In
the world of biomedicine, the question of whether a particular drug or procedure
is effective or not is settled in the arena of science – namely, well designed
and executed clinical studies. One doesn’t dismiss a treatment or procedure that
has a rational foundation (i.e., doesn’t violate established scientific laws or
principles) a priori – which is to
say, before conducting tests. But this has been exactly what many experts in
stem cell biology have done when it comes to the observations and data collected
and reported by SRI. Rather than suggest the need for controlled studies to
determine whether or not the clinically significant improvements reported in
scores of patients treated with purified cord blood stem cells in This
is not the kind or degree of informed open-mindedness one would expect of highly
placed researchers in major institutes and universities. The
level of cautious open-mindedness among officials in many federal regulatory
agencies appears similarly lacking or compromised. Drs. Ghen and Cosgrove’s use of cord blood infusions to treat ALS
(cited above) provides one such example:
As
was mentioned previously, there were improvements in some of the ALS patients
treated, while others saw little or nothing or seemed to progress. There were
also side effects reported: Three
of Dr. Ghen’s patients reported passage of dark urine
starting a few hours after infusion and continuing for 24 hours or so.
Persistent dark urine can signal hemolytic anemia and/or kidney damage.
Additionally, one patient had heart palpitations that occurred for 30 seconds
about three to four times a day and lasted one week after the treatment.
But
perhaps because there were salutary results and no discernable permanent harm
done, the FDA expressed a willingness to allow individual patients to be treated
with cord blood on an individual basis. Treating physicians would apply for an
Emergency IND – something often granted to terminally ill patients who want to
receive an experimental drug or procedure. So
far, so good. However,
when Dr.
Nizar
Souayah,
personal
physician to ALS sufferer and decorated war veteran, Major Michael Donnelly
(ret) – a man who’d received a cord blood treatment and had a good response --
applied for an IND, it was turned down. The intervention of four congressmen and
a “ALS
patient Major Michael Donnelly (ret.), a decorated fighter pilot from Desert
Storm, received cord blood in 2002 through the kind assistance of the White
House Office for Veteran's Affairs. His first treatment, which led to partial
reversal of paralysis, was attended and approved by the V.A.'s Surgeon General.
Today, 18 months since the FDA stopped his treatments, Major Donnelly cannot
speak, breathe, eat, or move at all except to blink.” Some
patient advocates I have spoken with concerning the actions of the NIH and FDA
think there is something sinister afoot, indicative of corruption or even
conspiracy to keep cord blood stem cell research on the proverbial back burner.
In this writer’s opinion, the events and actions that have played out against
cord blood and cord blood stem cells do not reflect a conspiracy but, rather, a
way of doing business; a mechanism that works but which can lead to blind spots,
tunnel vision and bottlenecks. Case in point: Dr. Kathy Mitchell, a researcher
at the University of Kansas-Laurence and Harvard scientist Dr. Denise Faustman. Both of these accomplished scientists have
conducted research that points to the potential of cord blood stem cells for
treating kidney disease, stroke and diabetes. Although the NIH did fund their
basic research – Petri dish work – when it came time to get additional grants to
cover animal studies, doors that were once wide open were closed. The scientists
who were charged with reviewing Mitchell and Faustman’s grant applications ignored the wealth of data
that these two scientists furnished and instead awarded money to embryonic stem
cell research projects. Interestingly, these peer reviewers were also competing
against Dr. Faustman for different
grants. "The review
is totally different than every other segment of the economy," Faustman says. "If every time you wanted to open a dry
cleaners you had to go to 90 percent of your competitors and get a consensus,
what would be the chance you'd be able to open a profitable
business?" "I think
people who want embryonic stem cells just don't want [alternatives] to
work," Faustman said. [Quotes from “Miracle Cells,” February 8, 2005,
World Magazine MIRACLE
CELLS] Have
things changed since Mitchell and Faustman ran
head-long into the NIH’s funding turn
down? You tell me: A NIH clinical
trials database search done on May 13th – “using “cord blood” as the key word –
produced 98 trials, only one of which appears to be for a non-blood born disorder (Diabetes):
