University of Washington researchers may have found a key to helping people with degenerative blindness restore their sight.

UW Medicine researchers, working with researchers at the University of California and the University of Munich, say they have discovered a chemical that temporarily restores some vision to blind mice.

Theyre now working on an improved version that may someday work on people with retinitis pigmentosa, a genetic disease that is the most common inherited form of blindness, as well as age-related macular degeneration, the most common cause of acquired blindness in the developed world.

Researchers say because the chemical eventually wears off, it may offer a safer alternative to other experimental approaches for restoring sight, such as gene or stem cell therapies, which permanently change the retina. It is also less invasive than implanting light-sensitive chips in the eye.

The findings appear in the July 26th issue of the journal Neuron.

UW discovery could be cure for some blindness

MANILA, Philippines - Former President Gloria Macapagal-Arroyo might undergo stem cell therapy to improve her health, according to the alternative medicine facility in Tagaytay City that the Pampanga lawmaker visited Thursday.

Arroyo came to the facility complaining of difficulty in swallowing because of a bulge in her throat, according to a statement from the Green 8 Young Health & Wellness Center.

Her voice has also changed and she is losing weight because she can't swallow solid food. She also has angina, the center said.

Arroyo also complained of continuing neck and back pain.

"Our center is accepting her for possible stem cell therapy," the alternative medicine facility said. "The stem cell therapy is... strongly considered."

It said the Arroyo can undergo such therapy in the Tagaytay center while her physical therapy will continue at the Veterans Memorial Medical Center 4 times a week.

The Pampanga lawmaker is seeking treatment at the center through her sister, Cielo Macapagal-Salgado.

The center said Salgado was previously diagnosed with a cancerous lump in her breast.

"She consulted several doctors and was subsequently subjected to a myrad of treatment procedures. These, however, did not produce the desired results. When she came to our center she was cured of her cancer," it claimed.

Arroyo might undergo stem cell therapy

STEM cell therapy is being eyed to cure the neck and back pains and other illnesses of former president and now Pampanga Rep. Gloria Arroyo, alternative medicine doctor Antonia Park said yesterday.

Arroyo went to Parks Green and Young Health and Wellness Center in Tagaytay City yesterday morning for cleansing and alternative healing.

A guard at the La Vista Subdivision in Quezon City, who requested anonymity, said Arroyo left the subdivision at around 7:30 a.m., accompanied by a few staff and a personal nurse. She rode a white Nissan Patrol and her convoy included a gray Toyota Land Cruiser and a police escort.

Arroyo was granted bail Wednesday by a Pasay City court after finding that the electoral sabotage case against her was weak. She posted a P1-million cash bond.

Stem cell treatment involves the introduction of new adult stem cells into the damaged tissue in order to treat a disease or injury. The ability of new cells to regenerate is seen as having significant potential to replace diseased areas of the body, with minimal risk of rejection and side effects.

Park, in a statement distributed to the media, said Arroyo complained of difficulty in swallowing with choking due to her bulge along the posterior pharyngeal wall, together with a change of her voice and losing weight due to her difficulties of swallowing the food (solid) and angina as well as continuous neck and back pain.

Thats why our center is accepting her for possible stem cell therapy and another treatment of pain management and giving natural food by means of fresh fruit and vegetable juices for which management is warranted and which the stem cell therapy is contemplated and strongly considered, she said.

She said the stem cell therapy can be given by her clinic in Tagaytay while Arroyo can continue her physical therapy at the Veterans Memorial Medical Center four times a week.

Park said Arroyo can to go her district, referring to the second district of Pampanga, over the weekend provided she takes care to wear a brace and avoid talking too much so as to protect the bulging interior of the throat, and provided she resumes physical therapy as soon as possible.

Doctors say a County Monaghan teenager who made medical history by using his own stem cells to rebuild his throat is making a successful recovery.

Ciaran Finn-Lynch, 13, from Castleblayney, made medical history as the first child in the world to undergo the pioneering tracheal transplant.

He was born with a condition called Long Segment Tracheal Stenosis which meant he found it difficult to breathe.

Doctors say he has grown 11 centimetres in height and returned to school.

The surgery was a desperate attempt to save his life after earlier treatment failed.

Since the operation, Ciaran has been able to live a normal life free from medication to prevent his immune system rejecting the transplant.

He underwent the procedure at London's Great Ormond Street Hospital in March 2010.

It involved seeding stem cells taken from Ciaran's bone marrow into the collagen "skeleton" of a donor windpipe stripped of its own cells.

Once the structure was implanted, the stem cells were allowed to mature in his body, rather than the usual laboratory "bioreactor".

Boy's windpipe transplant success

The family immediately agreed and the operation took place at Great Ormond Street Hospital in March 2010.

Since then Ciaran, from County Down in Northern Ireland, has grown almost four-and-a-half inches (11cm) and he has returned to school. He has also been able to develop his musical interest as a drummer. A medical update is published in The Lancet today.

His family has declined to be interviewed, but at the time of the operation his mother Colleen said she and her husband Paul had got our boy back.

The procedure involved taking a windpipe from a 30-year-old Italian woman who had died and stripping it of living cells down to the inert collagen scaffold.

Four weeks later, Ciarans windpipe was removed. Sections of its lining were taken off and kept and the rest discarded. Bone marrow from Ciaran was harvested and the stem cells isolated.

The same day, the donor windpipe was inserted into Ciarans neck and his stem cells sprayed on to it.

Tiny sections of lining from his original windpipe were patched on to the replacement. These prompted the stem cells to turn into the right kind of tissue and kick-started growth of the windpipe lining.

Finally, the graft was injected with proteins to stimulate cell growth and differentiation, called cytokines.

The operation was the first attempt to grow stem cells in place in the body of a child, rather than growing an organ in a laboratory bioreactor.

It came only two years after the first windpipe replacement using stem cells in an adult, although in that case, carried out in Barcelona, the organ was grown in the lab.

It's official: stem cells are drugs. At least, that's the opinion of the US district court in Washington DC, which has ruled that the Food and Drug Administration (FDA) has the authority to regulate clinics offering controversial stem cell therapies.

Treatments in which stem cells are harvested from bone marrow and injected straight back into the same patient are deemed part of routine medical practice - not regulated by the US government. But if the cells are subjected to more than "minimal manipulation", the FDA maintains that the therapy becomes a "drug", which must be specifically approved for use.

It was on this basis that in 2008 the FDA began moves to shut downRegenerative Sciences, a clinic in Broomfield, Colorado, that treats orthopaedic problems using a stem cell therapy called Regenexx.

Regenerative Sciences challenged the FDA's authority to regulate its activities, setting the stage for a legal fight. In 2010, the FDA sought an injunction to take Regenexx off the market. This has now been granted in the court's ruling.

Christopher Centeno, medical director of Regenerative Sciences, vows to appeal. "This is really round one," he says. "Our position remains that a patient's cells are not drugs."

Regenexx consists of mesenchymal stem cells, which give rise to tissues including bone and cartilage, taken from a patient's bone marrow and grown in culture for about two weeks. Centeno has published a series of case reports describing its use to treat joint problems - but no controlled clinical trials.

"I think it's a good ruling, and I'm glad to see that that the FDA has exercised its muscle on the case," says Christopher Scott, who heads the Program on Stem Cells in Society at Stanford University in California.

Scott hopes that the FDA will now step up its efforts to regulate other clinics offering unproven stem cell therapies. These include Celltex of Sugar Land, Texas, which rose to prominence after Texas governor Rick Perry was injected with stem cells supplied by the company to aid his recovery from back surgery.

Last month, the Houston Chronicle revealed that FDA inspectors had found multiple violations of good manufacturing practice at Celltex.

ScienceDaily (July 25, 2012) With an eye to the future, the results will let cells be obtained in the laboratory that can be transplanted into leukemia patients with no compatible donors.

Researchers from IMIM (Hospital del Mar Medical Research Institute) have deciphered the function executed by a protein called -catenin in generating blood tissue stem cells. These cells, also called hematopoietic, are used as a source for transplants that form part of the therapies to fight different types of leukemia. The results obtained will open the doors to produce these stem cells in the laboratory and, thus, improve the quality and quantity of these surgical procedures. This will let patients with no compatible donors be able to benefit from this discovery in the future.

The study, executed jointly with the Erasmus Medical Center Stem Cell of Rotterdam and published in the Journal of Experimental Medicine, analyzed a chain of molecular reactions that are produced inside some embryonic cells and that play a role in the creation of a hematopoietic stem cells. 'Our study contributes to deciphering the code that makes a precursor cell that is only found in the embryo become a hematopoietic stem cell. In order for that to happen, the -catenin protein must be activated for a while and with a specific dosage' explains Dr Anna Bigas, head of the IMIM Stem Cells & Cancer Group and lead researcher.

This protein also plays a fundamental role in the cells that originate and maintain some types of leukemia. 'The parallelisms between normal and leukemia stem cells prove to us that the molecular pathways that regulate both populations are the same. For this reason, our work will help us understand the origin of these diseases', argues Dr Bigas.

In addition to embryonic stem cells, each of our body's organs has another type of stem cell that has the capacity to regenerate all the cells for the tissue in question. However, they are only formed in the embryonic stage and are maintained for the rest of our lives. hematopoietic stem cells are part of the blood and, when they are transplanted, they are the inception for all of this tissue's cells.

At present, transplanting these cells is dependent on the availability of compatible donors. Nonetheless, there is still a high percentage of patients with no donors and that, therefore, cannot be submitted to this procedure. The results of this article lay the foundations so that, in the future, these patients can benefit from a source of laboratory-generated hematopoietic stem cells created from compatible embryonic cells or other types of expressly transformed cells.

Key function of protein discovered for obtaining blood stem cells as source for transplants

25 July 2012 Last updated at 21:04 ET By James Gallagher Health and science reporter, BBC News

The first child to have pioneering surgery to rebuild his windpipe with his own stem cells is doing well and is back in school.

Ciaran Finn-Lynch, who is now 13, had the ground-breaking surgery at London's Great Ormond Street Hospital in 2010.

Using Ciaran's own cells meant his immune system would not reject, and attack, the organ.

His surgeons said things were going well so far and that Ciaran could live the life of a normal teenager.

He was born with long-segment tracheal stenosis, which causes breathing difficulties. His lungs collapsed on the day he was born and he had major surgery to reconstruct his airways when he was six days old.

Metal tubes were used to hold his airways open, but in 2009 one caused huge amounts of bleeding when it damaged the main blood vessel coming out of the heart.

It was at this stage surgeons tried a pioneering operation. Instead of growing a new windpipe, they took a donor windpipe and stripped it of all the donor's cells. What was left was a three-dimensional web of collagen fibres which was transplanted into Ciaran.

Meanwhile, stem cells, which can become any other type of cell, from nerve to skin cells, were taken from Ciaran's bone marrow. These were then sprayed onto the newly transplanted windpipe.

The surgery had been tried once before in Spain, in 2008, on a 30-year-old woman, but Ciaran was the first child.

Stem-cell op child 'doing well'

MOBILE, Alabama -- Adult stem cells extracted during liposuction can be used to grow healthy new small-diameter blood vessels for use in heart bypass surgery and other procedures, new research shows.

The findings were presented today at the American Heart Association's Basic Cardiovascular Sciences 2012 Scientific Sessions in New Orleans.

The reason that's important, health officials said, is because millions of cardiovascular disease patients are in need of small-diameter vessel grafts for procedures requiring blood to be routed around blocked arteries.

These liposuction-derived vessels, grown in a lab, could help solve major problems associated with grafting blood vessels from elsewhere in the body or from using artificial blood vessels that are not living tissue, said Matthias Nollert, Ph.D., the lead author of the study, in a written statement.

Now, Nollert said, "small-diameter vessel grafts carry an inherent risk of clotting, being rejected or otherwise failing to function normally."

Nollert said the engineered blood vessels have good mechanical properties and "we believe they will contract normally when exposed to hormones. They also appear to prevent the accumulation of blood platelets -- a component in blood that causes arteries to narrow."

Here's how it works:

In the study, according to the American Heart Association, adult stem cells derived from fat are turned into smooth muscle cells in a laboratory, and then "seeded" onto a very thin collagen membrane.

As the stem cells multiplied, the researchers rolled them into tubes matching the diameter of small blood vessels. In three to four weeks, they grew into usable blood vessels.

Creating blood vessels with this technique has the potential for "off-the-shelf" replacement vessels that can be used in graft procedures, Nollert said.

In a Tissue-Engineering First, Doctors Think the Boy's New Windpipe Could Grow

July 25, 2012 -- Ciaran Finn-Lynch is an accidental medical pioneer. With his life in danger, doctors used the 13-year-old's own stem cells to grow him a new windpipe, and they did it inside his body -- a feat that's never been accomplished before.

"It's a really heroic story," says Harald C. Ott, MD, an instructor of medicine at Harvard Medical School in Boston. "They really saved this kid's life."

Ott worked out some of the science that made the procedure possible but was not directly involved in Ciaran's treatment.

Two years after the surgery, doctors say Ciaran (pronounced KEER-an) is living the life of a normal teen. He's grown more than 4 inches and gone back to school. Best of all, he has no need for an expensive and complicated regimen of anti-rejection drugs.

What doctors are learning from his case could help thousands of children born each year with life-threatening birth defects.

Ciaran was born with a windpipe so small and deformed that it caused his lungs to collapse.

Doctors managed to hold his airway open using metal tubes. But eventually the tubes eroded into his aorta, the large vessel that carries blood out of the heart. He was rushed to the hospital with massive bleeding. Twice.

The second time, the bleeding stopped on its own. That gave his doctors a small window of time to look for other options.

Two years earlier, scientists had devised a new way to create organs using a patient's own stem cells. Though the technique had only been tried in adults, they thought the same method might work for Ciaran.

Scientists have turned back the hands of a biological clock to rejuvenate ageing and damaged human heart cells.

Using stem cells, they reset a molecular mechanism that determines the rate at which cells age.

Although the work on human cells was confined to the laboratory, the same technique has been successfully tested in mice and pigs.

Researchers in the US managed to get new heart tissue to grow in the animals in just four weeks.

They hope the advance will lead to new treatments for heart failure, which often follows a heart attack.

'Modifying aged human cardiac cells from elderly patients adds to the cell's ability to regenerate damaged heart muscle, making stem cell engineering a viable option,' said lead scientist Dr Sadia Mohsin, from San Diego State University in California.

During heart failure the damaged heart is not strong enough to pump blood around the body efficiently, leading to rapid exhaustion.

In the laboratory studies, Dr Mohsin's team worked on heart tissue surgically removed from elderly patients.

Stem cells from the samples were treated with a growth protein called PIM-1.

The effect was to boost activity of an enzyme called telomerase, which has a direct impact on ageing.

The finding involves the cancer gene RhoC, which has previously been shown to promote metastasis of many types of cancer. RhoC levels increase as breast cancer progresses and high levels of RhoC are associated with worse patient survival.

Cancer stem cells are the small number of cells within a tumor that are believed to fuel the tumor's growth and spread. Researchers believe traditional chemotherapy and radiation treatments often become ineffective because they do not kill the cancer stem cells, and that the key to future treatments is to develop drugs that target and kill these cells.

This new study, which appears online in PLoS ONE, suggests a new way to get at the cancer stem cells.

"Targeting the specific molecular cogs driving the cancer stem cell machinery responsible for the cancer spreading has potential for future treatments. Eliminating cancer stem cells may ultimately be necessary to cure certain cancers, but in the meantime, we may be able to manage the cancer stem cell population and the invasive behaviors of these cells by disrupting the molecular machinery, using RhoC as a target," says senior study author Sofia D. Merajver, M.D., Ph.D., professor of internal medicine and epidemiology at the University of Michigan and scientific director of the breast oncology program at the U-M Comprehensive Cancer Center.

The researchers looked at breast cancer cell lines that were highly metastatic and cell lines from normal breast tissue. By inhibiting or overexpressing RhoC, they found that RhoC expression is necessary to cause metastasis in both cell lines, and that RhoC overexpression alone can cause metastasis. The researchers also tested this in mice and had similar results.

Merajver's lab, in conjunction with other U-M researchers, is studying a novel small molecule drug to inhibit RhoC, which has shown promising initial results in the laboratory. The researchers are continuing to develop this inhibitor, which will require several years of additional testing in the laboratory before potentially advancing to clinical trials.

Researchers find driver of breast cancer stem cell metastasis

NEW ORLEANS, July 23 (UPI) -- U.S. scientists said they modified stem cells that rejuvenated damaged and aged heart tissue in older heart failure patients.

Sadia Mohsin, a postdoctoral research scholar at San Diego State University's Heart Institute, said the finding could one day lead to new treatments for heart failure patients.

Modified human stem cells helped the signaling and structure of the heart cells, which were biopsied from elderly patients, Mohsin explained.

The researchers modified the stem cells in the laboratory with PIM-1 -- a protein that promotes cell survival and growth, Mohsin said.

Cells were rejuvenated when the modified stem cells enhanced activity of the enzyme telomerase, which elongates telomere length. Telomeres are "caps" on the ends of chromosomes that facilitate cell

replication. Aging and disease results when telomeres break off.

"There is no doubt that stem cells can be used to counter the aging process of cardiac cells caused by telomere degradation," Mohsin said in a statement.

The technique increased telomere length and activity, and increased cardiac stem cell proliferation, all vital steps in combating heart failure, Mohsin told the American Heart Association's Basic Cardiovascular Sciences scientific sessions.

ScienceDaily (July 24, 2012) Researchers at the University of Michigan Comprehensive Cancer Center have found that a cancer gene linked to aggressive spread of the disease promotes breast cancer stem cells. The finding implies a new way to target the behavior of these lethal cells.

StemCells Inc. hopes a clinical trial of its proprietary stem cells in rodents will lead to a clinical trial with Alzheimer's patients.

Neurosphere: StemCells is testing neuronal stem cells, which form floating aggregates when grown in culture, as a treatment for Alzheimers disease, spinal cord injury, and other neurological conditions. StemCells Inc.

Last week, a California biotech company announced that its human stem cells restored memory in rodents bred to have an Alzheimer's-like conditionthe first evidence that human neural stem cells can improve memory.

The company, called StemCells, is betting that its proprietary preparation of stem cells from fetal brain tissue will take on many different roles in the central nervous system. The company and its collaborators have already shown that its stem-cell product has potential in protecting vision in diseased eyes, acting as brain support cells, or improving walking ability in rodents with spinal cord injury.

This metamorphic ability is not so surprisingthey are stem cells, after all. But experts say the quality of scientists involved in StemCells and the interesting properties of its cells sets the company apart. "They've really been steadfast in their work to get these cells into clinical trials. That is a tough road and they've done it," says Larry Goldstein, a neuronal stem-cell researcher and director of UC San Diego's stem-cell program.

The company discovered the technique to isolate these cells from brain tissue in 1999 and has since spent some $200 million improving the technology. "Now we are really in the exciting phase, because now we are looking at human clinical data, as opposed to just small animals," says StemCells CEO Martin McGlynn.

His company is not the only group bringing stem cells into the clinic. While much attention was paid to Geron's departure from the world's first embryonic stem cell trial (see "Geron Shuts Down Pioneering Stem-Cell Program"), many other groups have continued to push their non-embryonic stem-cell therapies forward for leukemia, colitis, stroke, and more. Meanwhile, Advanced Cell Technology continues its U.K.-based embryonic stem-cell therapy trials for blindness. Non-embryonic stem cells can come from a variety of sourcesbone marrow, blood, as well as donated aborted fetal tissue, as is the case with StemCells and Neuralstem, another company focused on neuronal stem cells. In recent years, scientists have also developed methods for turning normal adult cells into stem cells (so-called induced pluripotent stem cells), but their safety has yet to be tested in humans.

So while StemCells is not a lone wolf, it may well be a pack leader. One of StemCells' first human studies involved a small trial of young children with a rare and fatal neurodegenerative disease called Batten disease. In 2006, the company began the first U.S. Food and Drug Administration-authorized trial of human neural stem cells at Oregon Health and Science University. Through small boreholes in the skull, a neurosurgeon implanted as many as a billion neural stem cells into different locations of the brains of six Batten patients.

The trial has since suggested that the cells are safe and integrate into the brain. At first, the children received immune system-suppressing drugs to prevent their body from rejecting the cells. But after a year, that treatment was stopped. "A big question that we had, that science had, that the FDA had, was what happens to these cells when you withdraw immunosuppression?" says McGlynn.

The treatment, however, did not rescue the children from the effects of the disease, and some have since succumbed to the disorder. Some of the parents of the children who passed away gave permission for an autopsy, enabling the scientists to see that even after one and a half years with no immunosuppression, the transplanted cells had survived. The company wanted to try the cellular therapy in children at an earlier stage of the disease, but was unable to find eligible patients at such a point in the disease course and canceled the trial.

Human Stem Cells Found to Restore Memory

WALTHAM, Mass.--(BUSINESS WIRE)--

Regenerative medicine company Histogenics Corporation, announced today the completion of a $49 million round of financing. The syndicate was led by Sofinnova Ventures with participation from additional new investors Split Rock Partners, BioMed Ventures and FinTech GIMV Fund, L.P. Existing investors ProChon Holdings BV, Altima Partners, Foundation Medical Partners, Inflection Point Capital and Boston Millennia Partners also participated in the financing. Proceeds will be used to complete the ongoing Phase 3 clinical program for lead product candidate NeoCart, which is currently enrolling patients. NeoCart is an autologous neocartilage tissue implant that utilizes the patients own cells to regenerate cartilage in patients suffering from cartilage lesions in the knee. Funds will also support efforts to obtain regulatory clearance in the European Union for product candidate VeriCart, a single-step, cell-free collagen scaffold uniquely designed to be used in conjunction with the patients own stem cells, to repair small cartilage defects frequently observed in meniscal and anterior cruciate ligament repair procedures. Garheng Kong, MD, PhD of Sofinnova Ventures and Josh Baltzell of Split Rock Venture Partners will join Histogenics Board of Directors. Arnold Freedman of Boston Equity Advisors served as the exclusive placement agent.

Patrick ODonnell, President and Chief Executive Officer of Histogenics, commented, We believe the quality of the investors and the significant level of commitment demonstrated in this financing speak to the potential of our product candidates to transform the treatment of cartilage injury with the goal of returning patients to their pre-injury level of activity. Each year, 1.8 million active adults and elite athletes undergo arthroscopy for the diagnosis and treatment of painful cartilage defects in the knee. With continued positive clinical results, we believe our Phase 3 product candidate, NeoCart, has considerable potential as a much-needed treatment alternative for a significant portion of these patients. The successful completion of this financing fully funds the Company to reach key clinical and commercial milestones for NeoCart and VeriCart and allows us to focus our full attention on continued successful clinical and regulatory execution.

Garheng Kong, MD, PhD, General Partner of Sofinnova Ventures added, NeoCart has the potential to dramatically change the way knee cartilage injuries are treated. Current treatments for knee cartilage damage frequently do not produce the lasting effects that individuals need to avoid serious knee pain and improve functionpreventing them from getting back to their active, daily lives. Published data have shown that patients treated with NeoCart experienced a very durable response that is sustained throughout a period of four years or more. Sofinnova is pleased to support Histogenics efforts to receive approval for NeoCart and address this unmet clinical need.

About NeoCart NeoCartis an autologous bioengineered neocartilage grown outside the body using the patients own cells for the regeneration of cartilage lesions. NeoCart recently entered a Phase 3 clinical trial after reporting positive Phase 2 data, in which all primary endpoints were met, and NeoCart was found to be generally well tolerated.

About VeriCart VeriCart is a single step, off-the-shelf, cell-free collagen scaffold, specifically designed for cartilage applications, which when reconstituted with the patients own bone marrow or augmenting marrow stimulation procedures, is intended for the improved repair of cartilage tissue. VeriCart is currently in development.

About Histogenics Histogenics is a leading regenerative medicine company that combines cell therapy and tissue engineering technologies to develop highly innovative products for tissue repair and regeneration. In May of 2011, Histogenics acquired Israeli cell-therapy company ProChon BioTech. Histogenics flagship products focus on the treatment of active patients suffering from articular cartilage derived pain and immobility. The Company takes an interdisciplinary approach to engineering neocartilage that looks, acts and lasts like hyaline cartilage. It is developing new treatments for sports injuries and other orthopedic conditions, where demand is growing for long-term alternatives to joint replacement. Histogenics has successfully completed Phase 1 and Phase 2 clinical trials in which the NeoCart autologous tissue implants effectiveness is compared to that of standard microfracture surgery.

New Rochelle, NY, July 24, 2012A naturally occurring line of immunodeficient pigs can support the growth of human tumors injected under their skin, offering a promising new large animal model for studying human cancers and testing new drugs and treatment strategies. The ability of human melanoma cells and pancreatic carcinoma cells to grow in these pig models is described in an article in BioResearch Open Access, a new bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc. (http://www.liebertpub.com). The article is available free online at the BioResearch Open Access website (http://www.liebertpub.com/biores).

Mathew Basel and colleagues, Kansas State University (Manhattan, KS) and Iowa State University (Ames), highlight the advantages that pig disease models offer, as they are anatomically and physiologically more closely related to humans than traditional rodent animal models. As a result, findings from studies in large animal models such as pigs are more likely to translate into similar outcomes in humans. The authors present their findings in the article "Human Xenografts Are Not Rejected in a Naturally Occurring Immunodeficient Porcine Line: A Human Tumor Model in Pigs" (http://online.liebertpub.com/doi/full/10.1089/biores.2012.9902).

"This novel animal model has the potential to become a highly useful model in cancer research studies, in addition to providing significant opportunities for drug discovery and other translational applications," says Editor-in-Chief Jane Taylor, PhD, MRC Centre for Regenerative Medicine, University of Edinburgh, Scotland.

Despite having to negotiate a more challenging regulation process biotech companies have continued to show investors strong gains in 2012. The FDA Amendments Act of 2007 forced regulators to increase standards for approvals of new drugs, introducing mandatory risk evaluation and mitigation strategies. According to a Pharmaceuticals & Biotechnology report from IMAP, several pharmaceutical firms have altered their drug portfolios from primary care driven blockbusters towards specialties such as oncology, immunology and inflammation, where the medical need is "so high that prices are more easily accepted by the regulators."
