Seven years ago I stood on a bridge over the M40 doing a "piece to camera" for a report about spinal repair. The aim was to come up with a metaphor for how researchers at University College London were trying to overcome spinal cord paralysis.

It went something like this: "Imagine your spinal cord as a motorway, the cars travelling up and down are the nerve fibres carrying messages from your brain to all parts of the body. If this gets damaged the cars can't travel. The messages are blocked, the patient is paralysed.

"Normally there is no way of repairing a severed spinal cord. But the team at UCL took nasal stem cells, and implanted them into the area of damage. These formed a bridge, along which the nerve fibres re-grew and re-connected."

This is the World-Cup of neurorehabilitation. Our rats have become athletes when just weeks before they were completely paralysed.

The research at the Spinal Repair Unit at UCL involved rats, not humans. In my TV report we showed rats unable to climb a metal ladder after one of their front paws had been paralysed to mimic a spinal cord injury. But after an injection of stem cells, the rats were able to move nearly as well as uninjured animals.

The hope then - and now - is that such animal experiments will translate into similar breakthroughs with patients. Seven years on and the team at UCL led by Professor Geoff Raisman are still working on translating this into a proven therapy for patients. He told me "This is difficult and complex work and we want to ensure we get things right."

So it was with a sense of caution that I approached some Swiss research in the latest edition of the journal Science in which paralysed rats were able to walk again after a combination of electrical-chemical stimulation and rehabilitation training.

The research prompted some newspaper reports talking of "new hope" for paralysed patients. The lead researcher, Professor Gregoire Courtine enthused: "This is the World-Cup of neurorehabilitation. Our rats have become athletes when just weeks before they were completely paralysed."

My colleague James Gallagher has reported on the research and you can read his copy here.

'Hope' for the paralysed?

LONDON Scientists in Switzerland have restored full movement to rats paralyzed by spinal cord injuries in a study that spurs hope that the techniques may hold promise for someday treating people with similar injuries.

Gregoire Courtine and his team at Ecole Polytechnique Federale de Lausanne saw rats with severe paralysis walking and running again after a couple of weeks following a combination of electrical and chemical stimulation of the spinal cord together with robotic support.

"Our rats are not only voluntarily initiating a walking gait, but they are soon sprinting, climbing up stairs and avoiding obstacles," said Courtine, whose results from the five-year study will be published in the journal Science on Friday.

Courtine is quick to point out that it remains unclear if a similar technique could help people with spinal cord damage but he adds the technique does hint at new ways of treating paralysis.

Other scientists agree.

"This is ground-breaking research and offers great hope for the future of restoring function to spinal injured patients," said Elizabeth Bradbury, a Medical Research Council senior fellow at King's College London.

But Bradbury notes that very few human spinal cord injuries are the result of a direct cut through the cord, which is what the rats had. Human injuries are most often the result of bruising or compression and it is unclear if the technique could be translated across to this type of injury.

It is also unclear if this kind of electro-chemical "kick-start" could help a spinal cord that has been damaged for a long time, with complications like scar tissue, holes and where a large number of nerve cells and fibres have died or degenerated.

Nevertheless, Courtine's work does demonstrate a way of encouraging and increasing the innate ability of the spinal cord to repair itself, a quality known as neuroplasticity.

Other attempts to repair spinal cords have focused on stem cell therapy, although Geron, the world's leading embryonic stem cell company, last year closed its pioneering work in the field.

Paralyzed rats walk again in Swiss study

ARLINGTON HEIGHTS, Ill., May 29, 2012 (GLOBE NEWSWIRE) -- Adipose stem cells (ACSs)--stem cells derived from fat--are a promising source of cells for use in plastic surgery and regenerative medicine, according to a special review in the June issue of Plastic and Reconstructive Surgery(R), the official medical journal of the American Society of Plastic Surgeons (ASPS).

But much more research is needed to establish the safety and effectiveness of any type of ASC therapy in human patients, according to the article by ASPS Member Surgeon Rod Rohrich, MD of University of Texas Southwestern Medical Center, Dallas, and colleagues. Dr. Rohrich is Editor-in-Chief of Plastic and Reconstructive Surgery.

Adipose Stem Cells--Exciting Possibilities, but Proceed with Caution

The authors present an up-to-date review of research on the science and clinical uses of ASCs. Relatively easily derived from human fat, ASCs are "multipotent" cells that can be induced to develop into other kinds of cells--not only fat cells, but also bone, cartilage and muscle cells.

Adipose stem cells promote the development of new blood vessels (angiogenesis) and seem to represent an "immune privileged" set of cells that blocks inflammation. "Clinicians and patients alike have high expectations that ASCs may well be the answer to curing many recalcitrant diseases or to reconstruct anatomical defects," according to Dr. Rohrich and co-authors.

However, even as the number of studies using ASCs increases, there is continued concern about their "true clinical potential." The reviewers write, "For example, there are questions related to isolation and purification of ASCs, their effect on tumor growth, and the enforcement of FDA regulations."

Dr. Rohrich and co-authors performed an in-depth review to identify all known clinical trials of ASCs. So far, most studies have been performed in Europe and Korea; reflecting stringent FDA regulations, only three ASC studies have been performed in the United States to date.

Many Different Uses, But Little Experience So Far

Most ASC clinical trials to date have been performed in plastic surgery--a field with "unique privileged access to adipose tissues." Plastic surgeon-researchers have used ASCs for several types of soft tissue augmentation, such as breast augmentation (including after implant removal) and regeneration of fat in patients with abnormal fat loss (lipodystrophy). Studies exploring the use of ASCs to promote healing of difficult wounds have been reported as well. They have also been used as a method of soft tissue engineering or tissue regeneration, with inconclusive results.

In other specialties, ASCs have been studied for use in treating certain blood and immunologic disorders, heart and vascular problems, and fistulas. Some studies have explored the use of ASCs for generating new bone for use in reconstructive surgery. A few studies have reported promising preliminary results in the treatment of diabetes, multiple sclerosis, and spinal cord injury. No serious adverse events related to ASCs were reported in either group of studies.

Fat-Derived Stem Cells Show Promise for Regenerative Medicine, Says Review in Plastic and Reconstructive Surgery(R)

Hip replacements for some patients could be a thing of the past after surgeons pioneered a new stem cell procedure to tackle a bone disease that leads to arthritis.

Doctors at Southampton General Hospital are extracting stem cells from the bone marrow of patients in need of hip repair due to osteonecrosis - a condition where poor blood supply causes significant bone damage leading to severe arthritis.

These cells are mixed with cleaned, crushed bone from another patient who has had their own hip replaced and used to fill the hole made by surgeons after dead and damaged tissue has been removed from the joint.

The procedure has been developed by Doug Dunlop, a consultant orthopaedic surgeon at Southampton General Hospital, and Professor Richard Oreffo, a specialist in musculoskeletal science at the University of Southampton.

"Although this work is still ongoing, several patients who have had the procedure have reacted very well and, if we get the results we are hoping for, these patients won't need to have their hip joints replaced - they should be fixed completely," said Mr Dunlop.

Professor Oreffo added: "By using stem cells to send out chemical signals to blood vessels, we hope the body will continue to create new vessels in the hip which supply enough nutrients to maintain bone strength."

Osteonecrosis is on the rise in the UK with around 4,000 cases a year but it is much more widespread in Asia where it is the most common form of arthritis of the hip, the hospital said.

It can also be treated with drugs to help avoid arthritis and usually strikes between 30 and 50 years of age.

Osteonecrosis is one of the three main causes of arthritis alongside osteoarthritis and rheumatoid arthritis.

Arthritis in general affects one in five people in the UK.

Cell therapies for cardiovascular-related conditions is a closely watched, much studied, oft-discussed, and hotly contested segment of the cell therapy industry.


The data to-date are admittedly confusing.  From a clinical perspective, the studies for which we have data have been relatively small involving a mish-mash of indications, endpoints, eligibility criterion, methods and/or route of administration, as well as the time of administration relative to event or disease progression.


Further compounding any interpretation of the data, from a technical perspective, is the fact the products have been widely varied in terms of being autologous vs allogeneic, expanded and not, genetically modified and not, from a plethora of different sources, and utilizing a wide variety of cell types from skelatal myoblasts, cardiomyocytes, mesenchymal stromal cells, mononuclear cells, etc. 


All this makes it extremely difficult to draw any conclusions with respect to what's working and what's not.  We will not attempt to do so.


All we do below is attempt to give a snapshot of the industry-sponsored cell therapy trials currently ongoing for cardiovascular-related conditions.  So here it is:


Commercial:
Pharmicell's Heartcelligram is the only cell therapy to have received regulatory approval for commercial distribution for the treatment of a cardiac-related indication.  Heartcelligram is an autologous cell therapy approved in 2011 by the Korean Food and Drug Administration (KFDA) for the treatment of Acute Mycardial Infarction (AMI).  The price is reportedly $19,000 and the trial data behind the approval has not yet been published in a peer-reviewed journal.


Phase III or II/III:
There are currently only 3 active and recruiting cardiac-related, industry-sponsored cell therapy trials.  Interestingly they all involve autologous products, two involve devices, two involve centralized manufacturing, two involve bone marrow cells as a source, two are only in European clinical sites, and two are targeting ischemic-related conditions.

• Baxter Therapeutics' Auto-CD34+ cells
• phase III trial actively recruiting
• Indication:  refractory angina and chronic myocardial ischemia
• Estimated enrollment:  444
• Estimated primary completion: June 2016 
• Cytori
• phase II/III trial actively recruiting
• Indication: ST-elevation acute myocardial infarction
• Estimated enrollment: 360
• Estimated primary completion: July 2014

• Miltenyi Biotec
• phase III trial actively recruiting
• Indication: myocardial ischemia or coronary artery disease
• Estimated enrollment: 142
• Estimated primary completion: July 2012

In the last couple of weeks, two
well-respected Los Angeles Times columnists have visited what
might be called the "Son of CIRM" initiative on the
June ballot in California. It is aimed at fighting cancer by spending
$800 million or so annually on research with the money coming from a
$1-a-pack tax on cigarettes.

"Prop. 29 would increase cancer
research. Reduce smoking. Save lives. Hurt the lying tobacco
companies. Good plan."

"Proposition 71, you may recall, was sold to a gullible
public via candy-coated images of Christopher Reeve walking
again and Michael J. Fox cured of Parkinson's.
The implication was that these miracles would happen if voters
approved a $3-billion bond issue for stem cell research. Who could be
against that? 

 "As it turned out, the stem cell
measure created an unwieldy bureaucracy and etched conflicts of
interest into the state Constitution. By last count about 85% of the
$1.3 billion in grants handed out by the program, or some $1.1
billion, has gone to institutions with representatives on the stem
cell board. The program is virtually immune to oversight by the
Legislature or other elected officials. For these reasons and others,
it has grappled with only mixed success with changes in stem cell
science and politics that have called its original rationale into
question."

"Proposition
29, similarly, places most spending from the tobacco tax in the hands
of a nine-member board that must comprise one cardiovascular
physician affiliated with a California academic medical center; the
chancellors of UC Berkeley, UC San Francisco and UC
Santa Cruz; two representatives of lobbying groups devoted to
tobacco-related illness (including one who has been treated for such
a disease); and three representatives from National Cancer
Institute-designated cancer centers in the state. There are
10 of the latter, including five UC campuses and the City of Hope.
Plainly, every member of the board will represent an employer that
thinks it's in line for some of the money."

"The anti-29 side is hitting this
hard: that the research money generated in California could be spent
out of state. And the politest thing possible to say about that claim
is that it's disingenuous. It's stretching something that's
conceivable into a virtual certainty."

"The anti-29 camp charges that
(the structure of the board) would allow a conflict of interest in
awarding contracts. But there are state laws that protect against
such conflicts.

"Anyway, the tobacco crowd can't have it
both ways: complaining that the money could be spent outside
California and also griping when the system is set up to practically
guarantee that it will be spent in California."

"Gov. Brown's latest budget
proposal calls for cuts of $1.2 billion in Medi-Cal and
$900 million in CalWorks (a relief program for families with
children) and steep cuts in financial aid for college students and in
court budgets. The University of California and Cal State systems are
becoming crippled by 20 years of cutbacks in state funding,
leading to soaring tuition charges. Tobacco-related illnesses create
some of the burden on Medi-Cal and other public healthcare programs,
yet a minimal portion of Proposition 29 revenue, if any, would go to
helping taxpayers carry that burden. 

"With the overall state budget gap
approaching $16 billion, how can anyone make the case for diverting a
huge chunk of $800 million a year in new revenue to long-term
scientific research, whether in California or not? Even if you
believe that case can be made, the proper place to make it is in the
Legislature, where all these demands on the budget can be weighed and
balanced against one another — not at the ballot box, where the
only choice is to spend it the way the initiative's drafters choose
or not to raise it at all."

“It’s not so much that [stem cell

as it’s the other avenues of research have grown and multiplied and

In a move that was long overdue, the $3
billion California stem cell agency last week hired a director of
information technology to straighten out key problems ranging from
its grants management system to how it handles its website.

Bill Gimbel

 "Integration
of website content management has not been an integral part of the
GMS (grants management system) development process, which could
result in suboptimal operational efficiency and effectiveness.

"Grants management system
development is effectively managed at a tactical level, but it lacks
dedicated, strategic governance and oversight, which has resulted in
an elongated development process and requirements conflicts."

"The new grants management system
intellectual property module, currently under development, does not
include provisions to address commercialization activity."

"CIRM board members and senior
management do not receive regularly updated, enterprise-level
performance information. The ability to evaluate performance against
strategic goals is critical to effective leadership and program
monitoring, evaluation, and reporting. CIRM does not currently have a
formal performance reporting program."

"Data and document access are
inefficient as a result of CIRM operating without a document
management system.....In most cases, CIRM staff cannot access
information without human interface. Information is stored in
multiple locations, which are not linked or indexed."

 "CIRM’s
information system needs have been met by a variety of tools,
including in-house developed applications, off-the-shelf
applications, databases, and spreadsheets, most of which are not
integrated," the audit stated.

Rachel Denny Clow/Caller-Times Cristina Rodriguez sits with her dogs Coby (left) and Flower at her home Thursday. Rodriguez, who has non-Hodgkin lymphoma, is having a Zumba benefit on Sunday and inviting people to register to donate bone marrow. Rodriguez is a former Zumba instructor.

CORPUS CHRISTI Had Cristina Rodriguez's cancer been more aggressive, had it penetrated her bones, things might have been different.

And while she has had chemotherapy, she has lost her hair and needs a stem cell treatment, but she doesn't need a bone-marrow transplant.

And for that, she's lucky.

Hispanics needing bone marrow have a harder time finding matching donors than do other ethnicities because few Hispanics have registered to donate.

"That could've easily been me," Rodriguez said.

That's why Rodriguez, 31, is trying to raise awareness about the importance for Hispanics to give bone marrow. The former Zumba instructor is hosting a Zumba event Sunday afternoon that partly is a fundraiser for her ongoing cancer treatments and partly a campaign to encourage more people to become donors.

Among the 8 million people signed up as bone marrow donors, 800,000 or 10 percent, identify themselves as Hispanic or Latino. Though Hispanics comprise more than one-third of Texas' population, only 17 percent of registered bone marrow donors in the state are Hispanic.

Overall, Hispanics have a 72 percent chance of finding a bone marrow donor, compared with whites, who have a 93 percent chance, according to the donor program. Only blacks fare worse, with a 63 percent likelihood of finding a donor.

This achievement is significant, as it opens up the prospect of treating heart failure patients with their own, human-induced pluripotent stem cells (hiPSCs) to fix their damaged hearts.

Furthermore, the cells would avoid being rejected as foreign as they would be derived from the patients themselves. The study is published in the European Heart Journal. However, the researchers state that it could take a minimum of 5 to 10 years before clinical trials could start due to the many obstacles that must be overcome before using hiPSCs in humans is possible.

Although there has been advances in stem cell biology and tissue engineering, one of the major problems scientists have faced has been lack of good sources of human heart muscle cells and rejection by the immune system. Furthermore, until now, scientific have been unable to demonstrate that heart cells created from hiPSCs could integrate with existing cardiovascular tissue.

"What is new and exciting about our research is that we have shown that it's possible to take skin cells from an elderly patient with advanced heart failure and end up with his own beating cells in a laboratory dish that are health and young - the equivalent to the stage of his heart cells when he was just born," said Professor Lior Gepstein, Professor of Medicine (Cardiology) and Physiology at the Sohnis Research Laboratory for Cardiac Electrophysiology and Regenerative Medicine, Technion-Israel Institute of Technology and Rambam Medical Center in Haifa, Israel, who led the study.

In the study, Professor Gepstein, Ms Limor Zwi-Dantsis, and their colleagues retrieved skin cells from two male heart failure patients, aged 51 and 61 years, and reprogrammed the cells by delivering 3 transcription factors (Sox2, Oct4, and Klf4) in addition to a small molecule called valproic acid, to the cell nucleus. The team did not include a transcription factor called c-Myc as it is a known cancer-causing gene.

Professor Gepstein said:

In addition, the team used an alternative strategy involving a virus transferred reprogramming data to the cell nucleus. However, the team removed the virus after the information had been transferred in order to avoid insertional oncogenesis.

IT'S current preservation for future regeneration - and now umbilical cord tissue is going on ice in Australia for the first time.

Usually discarded after birth, umbilical tissue from newborn babies is being collected and cryogenically frozen to be used one day for regenerative and stem cell medicine. And it doesn't just have potential for the babies involved, either. Experts say stem cells could also be used for family members who are genetically compatible.

It is hoped the cells will eventually be able to be used to repair damaged tissues and organs, with researchers investigating its uses for treating diseases like multiple sclerosis, cerebral palsy and diabetes, as well as for bone and cartilage repair.

Although cord blood storage has been available for many years, Cell Care Australia has added cord tissue storage in anticipation of new discoveries in the regenerative medicine field.

Cell Care Australia medical director associate professor Mark Kirkland said the storage process - already popular in the US, Europe and Southeast Asia - was long overdue for Australian shores.

"The science is developing around the world and we're really behind the rest of the world in providing parents the option to store these cells and we thought it was about time it was brought here," he said.

"It's finding a way to take what would otherwise be waste tissue and turning it into something of potential future value for not only your child but also potentially for other family members.'

Parramatta couple Tim and Padma Vellaichamy are among the first to use the service in Australia.

Mr Vellaichamy, 31, said he heard of the technology while working as a dentist in India and decided to store their daughter's cord cell tissue after birth three weeks ago.
