The
adult stem cell marketplace is one of the most dynamic areas in life
science today. There are an incredible number of scientific advancements,
especially since 2008 as a heated pace of research discoveries and
collaborations are underway among commercial companies, institutions
and even a multi-institutional, interdisciplinary network initiative
led by an executive department of the U.S. federal government.
Also, big pharma are beginning to invest heavily into regenerative medicine, and at least one state in the U.S. is proposing a bill that would create a special research consortium to maximize the benefits of adult stem cell research for its citizens.
Non-controversial
adult stem cells hold great hope for successful treatments
and potential cures. In recent years these cells have provided therapeutic
benefits to human patients for 70+ diseases and conditions. Adult
stem
cells exist within the body and have untapped potential to rescue
and heal
tissue and organs that have been injured or diseased. They can be
extracted from many types of tissues such as umbilical cord at birth,
peripheral, bone marrow, adipose (fat) tissue, menstrual-derived blood,
dental pulp, liver, skeletal muscle, placentas, and more.
A
service of the National Institutes of Health called ClinicalTrials.gov
(http://www.clinicaltrials.gov),
a registry of federally and privately
supported clinical trials conducted in the U.S. and around the world,
showed
at the end of March 2009 there were more than 2,300 adult stem cell
clinical
trials in various stages (completed, active, recruiting volunteers,
and not
yet recruiting) investigating these cells use as potential breakthrough
therapies for a myriad of diseases.
We
estimate there are up to 300 firms worldwide engaged in some aspect
of stem cell research and commercialization and the vast majority
of stem cell companies are focused on adult stem cells: allogenic
(taken from a different individual); autulogous (taken from an individual
and transferred back to original donor); or cultured. And it is becoming
increasingly clear that these stem cells can address up to 70 different
clinical indications. Much of what is motivating these early pioneer
patients is an existing
deep-seated demand for these therapies, according to Robin Young,
CFA, CEO of RRY Publications LLC, a market analysis firm in Wayne,
Pa. His analysis and market forecasts (2009 - 2019) were presented
at the 4th Annual Stem Cell Summit on February 17, 2009 in New York.
(Stem Cell Summit Executive Summary; http://www.ryortho.com;

All
three types of stem cells are now firmly in the marketplace. Over
the
course of the last four years, approximately 30,000 patients have
been
treated with allogenic stem cell products in the U.S.; 2,000
3,000 with
autologous stem cell products; and more than 1,000 with cultured stem
cell
products, stated the market report.
Stem cells as commercial products have demonstrable therapeutic value in 15 medical markets, according to Youngs analysis, such as heart muscle repair, nerve regeneration and diabetes treatment. In 2008 in the U.S., there were 35 million patients available for eventual stem cell therapeutic treatment in the 15 markets analyzed. By 2018, we forecast stem cells will be used therapeutically in as many as 2 million annual procedures for an aggregate market penetration of approximately 6%. These products will be generating, we estimate, well over $8 billion in revenue.
Cord
Blood Fastest Growing Therapy Group
Dallas Hextell is living proof of the healing power of adult stem
cells
there. He was diagnosed at eight months with cerebral palsy, which
has no
known cure. Fortunately, Dallas parents had his umbilical cord
blood stored
when he was born. He was accepted in a clinical trial at Duke University
in
July 2007 and was among the first in the country to be intravenously
infused
with his own cord blood stem cells to induce healing in his brain.
Soon
after his procedure Dallas parents began noticing improvements.
Today, with the help of therapists, Dallas is doing things no one
thought possible. He runs, he laughs, and hes beginning to talk.
When
babies are born, the umbilical cord is generally discarded. This is
partly because pregnant women and many of their doctors are unaware
that
life science has demonstrated cord blood cells have immense therapeutic
value. Increasingly families are educating themselves about cryogenic
storage of their childs cord blood because they understand recent
progress
has revealed it is a safe and ethical source of stem cells for therapeutic
use and the technology is evolving rapidly. These cells can be
cryogenically stored for more than 30 years. Its a one-time
opportunity,
said David Koos, Chairman and CEO of San Diego-based Bio-Matrix Scientific
Group, Inc. (OTC Bulletin Board: BMSN; http://www.BMSN.us).
BMSN, an emerging research and development biotechnology company, opened its commercial cryogenic stem cell banking and processing facility in 2008. As of January 2009 BMSN has entered into contractual agreements with private stem cell preservation companies and other entities for the cryogenic banking and processing of stem cells from cord blood and peripheral blood of those companies donors specimens. BMSN does not have any contact with donor clients.
The
Association of Family Cord Blood Banks estimated that about 750,000
cord blood collections are stored in private/family banks in the U.S.,
as of June 2008. The average cost of private cord blood banking in
the U.S. for an individual is approximately $2,000 for the collection
and about $125 per
year for storage, according to industry figures. There are often other
fees
involved.
Stem
cell treatments from umbilical cord blood are one of the fastest
growing therapy groups, and proven clinically effective for conditions
including cancers, leukemia, and sickle cell anemia. In fact, stem
cell
transplantation recently has overtaken bone marrow cell transplantation
in
total number of treatments, Young reported. As these therapies
become
more publicized, more effective, and more wide-reaching, the demand
for stem cells will grow from two primary factors: increasing numbers
of transplant patients, and increasing numbers of parents banking
cord blood as a sort of biological insurance. Young
also noted integral in the growth of the cord blood banking industry
is BioE Inc.s PrepaCyte-CB product line, a new standard for
cord blood processing, (http://www.bioe.com),
which is positioned to become the dominant and default cord blood
stem cell
processing technology.
Research
Validates New Direction for Storage
An important discovery announced on March 25, 2009 by researchers
at the National Institutes of Health (NIH; http://www.nih.gov),
which has
implications for Leukemia treatment and artificially culturing blood
cells,
validates a new direction for cryogenic stem cell storage facilities
that
meet rigid state and federal regulatory requirements. The researchers
deciphered a key sequence of events governing whether the stem cells
that
produce red and white blood cells remain anchored to the bone marrow,
or
migrate into the circulatory system a key discovery that will
advance
understanding of how blood cells and immune cells are generated.
The
findings of NIH researchers have implications for culturing
infection-fighting immune cells outside the body, where they could
be
temporarily held in storage during chemotherapy and other treatments
which
suppress the immune system. This discovery confirms a new trend for
commercial cryogenic storage facilities for research and treatment
of
diseases, and their important role in public and private stem cell
research
efforts now and into the future, said BMSNs Koos. Describing
BMSN as a
conservative player in the stem cell industry, he pointed
out that the
company is developing a unique niche within the stem cell industry
as a
place for stem cell companies to store blood specimens for research
and
treatment of diseases.
While
the concept of private cord blood banking started in the U.S. about
20
years ago, there has been tremendous growth worldwide in recent years.
A
useful global educational web site dedicated to informing expectant
parents
with unbiased and current information about how to choose a bank,
and all
the issues involved, is Parents Guide to Cord Blood (http://www.parentsguidecordblood.org),
based in Brookville, MD. The site
includes listings and snap-shot histories of each U.S. private and
public
cord blood bank. There are also descriptions of 150 cord blood banks
located worldwide.
According
to Youngs forecast: Worldwide estimates show the market
for cord blood processing and banking will grow by 25% over the next
five years (approaching $450 million annually for cord blood processing),
driven by surging demand in the U.S. and Western Europe (where an
estimated
one-quarter of all newborns will have banked cord blood) and exploding
demand in India, China and Latin America where processing is
just
beginning to take off.
Department
of Defense Creates AFIRM
Research is well underway among participating institutions since the
U.S.
Department of Defense announced in April 2008 the creation of a new
$250
million institution focused on research called the Armed Forces Institute
of
Regenerative Medicine (AFIRM). The virtual organization is a
multi-institutional, interdisciplinary network working to develop
advanced
treatment options over the next five years for severely wounded service
men
and women. AFIRM is managed and funded through the U.S. Army Medical
Research and Materiel Command (USAMRMC), with additional funding from
the U.S. Navy, U.S. Air Force, the National Institutes of Health,
the Veterans
Administration and local public and private matching funding.
AFIRM
has been designed to speed the delivery of regenerative medicine
therapies to treat the most critically injured service members from
around
the world, but in particular those coming from theaters of operation
in Iraq
and Afghanistan. There are five major programs: Limb Repair, Craniofacial
Repair, Burn Repair, Scarless Wound Repair and Compartment Syndrome
Repair.
AFIRM
is made up of two civilian research consortia working with the U.S.
Army Institute for Surgical Research (USAISR) in Fort Sam, Houston,
Texas.
One consortium is lead by Rutgers, The State University of New Jersey,
and
the Cleveland Clinic and the other is led by Wake Forest University
Institute for Regenerative Medicine and The McGowan Institute for
Regenerative Medicine at the University of Pittsburgh. Each of these
civilian consortia is itself a multi-institutional network. There
are a
total of 28 civilian institutions involved.
"Our
researchers are continuing to pursue promising avenues, such as tissue
regeneration of fingertips," said AFIRM Investigator William
Wagner, Ph.D., Deputy Director of the McGowan Institute for Regenerative
Medicine. "We are also testing in animal models materials that
could replace damaged abdominal wall muscles, and we might soon embark
on a novel strategy that uses muscle-derived stem cells to heal severely
injured tissue."
(http://www.mirm.pitt.edu)
Dozens
of commercial interests are expressing a willingness to work with
the
AFIRM consortia as commercialization partners. The medical device
industry has taken a keen interest in speeding these important new
therapies to market, not just for injured service members, but for
civilian patients as well. AFIRM believes this participation ultimately
will lead to better
healthcare options for all Americans.
All
of the research now being funded will use adult-derived stem cells
taken
from the patient or from another consenting adult. AFIRM has stated
adult
stem cells and progenitor cells are an integral part of normal wound
healing
and the formation of all new tissues. Many of the strategies being
developed by AFIRM seek to improve wound healing and tissue repair
by
increasing the number or improving the function of adult stem cells.
A
patients own cells, or in some cases, cells from another adult,
are used in
conjunction with special drugs called bioactive factors, or with advanced
biomaterials that serve as scaffold for growth of new tissues.
The
vision of the future is that before soldiers go off on operations
they
will have their own stem cells harvested through liposuction and stored
for
use if they get wounded. That way while a casualty is being stabilized
overseas, we will be in the U.S. growing them muscle, skin or bone
ready for surgery, Sgt. Glen Rossman of USAISR told Soldier
magazine (March 2009 issue).
Project
Director Col. Bob Vandre also commented: AFIRMs research
is very exciting news and should be very reassuring to soldiers. Some
day we will be able to fix a lot of things. We currently have 12 clinical
trials ready
to roll and that is a sign that AFIRM has arrived and is very much
for
real.
Big
Pharma Enter Arena
In what represents a major shift in the field, Pfizer announced in
November
2008 it would spend $100 million over five years to develop therapies
from
stem cells with the launch of Pfizer Regenerative Medicine
(http://www.pfizer-regenerativemedicine.com),
a global unit based in
Cambridge, MA and Cambridge, the UK.
The
U.S. unit is focusing on using stem cells to develop therapies for
cardiac disorders and cancer through in-house research and a vast
array of alliances and collaborations, and will grow its team to 20
scientists. The
U.K. arm will grow to 60 scientists over the next two years with a
focus
predominately on age-related and degenerative disorders with particular
interest in common cellular mechanisms and disorders of the central
and
peripheral nervous system.
Pfizer
Regenerative Medicine is operating as an independent research unit
and is basing its stem cell research and drug discovery efforts on
a full
set of drug discovery capabilities.
Earlier
in 2008, Pfizer invested $3 million with La Jolla, CA-based startup
EyeCyte, Inc. (http://www.eyecyte.com)
to develop treatments for
diabetes-induced retinal damage, a leading cause of blindness, using
patient blood and bone marrow-derived progenitor cells.
In
addition, Epistem Plc (http://www.epistem.co.uk),
the UK-based
biotechnology and research services company, announced in March 2009
that it had signed a research and development collaboration with Novartis
to
identify new drug targets and therapeutics across a variety of disease
areas. Epistem, which is focused on the regulation of adult stem cells
located in epithelial tissue, is commercializing its expertise in
the areas
of oncology, gastrointestinal and dermatological diseases.
Texas
Bill Would Create Research Consortium
To further adult stem cell research on the state level, Texas Senator
Jane
Nelson (R-Lewisville) and Chair of the Senate Health and Human Services
Committee, has authored Senate Bill 73 that would create the Adult
Stem Cell Research Consortium, which would encourage collaboration
between researchers at Texas universities and cord blood banks. This
body would oversee funding for adult stem cell research received from
both public and private sectors.
If
passed, the bill would move Texas beyond the debate about whether
it is
appropriate or inappropriate to destroy human embryos into the realm
of
adult stem cell research and treatments without ethical concerns.
It is
estimated that more than 1.2 million Texans are afflicted with chronic
degenerative conditions and can benefit from this research that could
lead
to the discovery of successful treatments and potential cures.
During
March 2009 Texas Medical Association physician leader James T.
Willerson, MD, who is President and Medical Director of Cardiology
Research, and Codirector of the Cullen Cardiovascular Research Laboratories
at Texas Heart Institute in Houston, and other authorities in the
states adult stem cell field testified before senators at the
Texas Senate Health and Human Services Committee meeting in Austin
in support of Senate Bill 73.
Cord
Blood Advancements Since 1st Transplant
In cord blood technology, 2008 marked the 20th anniversary of the
first cord
blood transplantation in the world, carried out by Eliane Gluckman,
MD,
Ph.D. The recipient of that pioneering effort, Matthew Farrow, now
26 years
old, continues in good health. He was born with a rare blood disorder
and
was expected to die before the age of 10. When he was five his parents
took part in a pioneering experiment in France to use stem cells from
his sisters umbilical cord when she was born.
Since
then, cord blood stem cells have been used in more than 14,000
transplants worldwide to treat more than 70 diseases in both adults
and
children and are now showing great promise for regenerative medicine
applications, including treatment for type 1 diabetes, brain injury,
cerebral palsy and hearing loss, according to Cord Blood Registry
(http://www.cordblood.com),
the worlds largest stem cell bank.
As
a result of pioneering work and the tremendous progress over the years,
for many families cord blood banking is the best option for treating
and curing disease, especially as they understand the importance of
umbilical cord donations for advancing the science, said Koos
of Bio-Matrix
Scientific Group.
