Two directors of the $3 billion
California stem cell agency have popped up in the battle over the
anti-tobacco initiative on tomorrow's ballot in the Golden State.

"The...problem with Proposition 29
is its pigeonholing of the money for cancer research rather than for
immediate needs here in California that are absolutely dire. It’s
all well and good to say that cancer research benefits everyone, but
the real question is whether it should be the absolute top priority
for a state that can’t afford to keep its children fed or offer
them medical care in the here and now. 

"Lansing and Vuori say the fact
that Prop. 29 'fails to provide funding for schools, roads or
affordable housing' is irrelevant, because it was 'was never intended
to solve these problems.'

"In the context of the state’s
needs, this is a rather callous approach to take. Let’s spell out
why, so Lansing and Vuori won’t be so inclined to dismiss these
necessities of life so casually."

"That’s just the beginning of
what might be cut because the state needs money—and won’t be able
to lay its hands on the hundreds of millions of dollars that Lansing,
Vuori, and their research colleagues are angling for. They don’t
want voters to be reminded that there are competing demands for the
tobacco money, and they do so by failing to mention that they exist,
and also by presenting the spending on cancer research as the voters’
only choice. 

"It’s the only choice because
the promoters of Proposition 29 designed it that way. Advocates of
programs like this love to pass them in via voter initiatives because
they leave no room to measure them against alternative needs."

"Organizers argued that the tax would have
less chance of passing if voters thought it would go into the state
coffers, and said that their only goal here was cutting down on
smoking."

Bone Marrow Transplant Milestone

Today is a big day for the Waikato Hospital Haematology Department and equally big for consultant haematologist Dr Humphrey Pullon who established the transplant service there 20 years ago.

The first autologous bone marrow transplant was carried out at Waikato Hospital on 25 June 1992 and was today celebrated with a patient afternoon tea, which about 120 transplant recipients attended.

By the end of the month we will have performed 317 transplants in 301 patients over the past 20 years, said Dr Pullon.

The first patient went down to Wellington to have her stem cells collected and they were then driven back up to be stored here She is still alive, but was unable to attend today.

We did the stem cell collection of the second patient, who is sadly no longer alive, and our third patient was cured of Lymphoma as a result of his transplant.

The third patient was Lloyd Given of Tauranga who attended todays afternoon tea.

I would like to extend my thanks to Waikato Hospital, Humphrey and the oncologist at the time, Grant Trotter, he said.

The autologous bone marrow transplant process is a long and involved one.The cancer patient is treated and goes into remission or gets to a point where the cancer is well controlled.

Bone Marrow Transplant Milestone

Scientists at the UCSF-affiliated Gladstone Institutes have for the first time transformed skin cells with a single genetic factor into cells that develop on their own into an interconnected, functional network of brain cells.

The research offers new hope in the fight against many neurological conditions because scientists expect that such a transformation or reprogramming of cells may lead to better models for testing drugs for devastating neurodegenerative conditions such as Alzheimers disease.

Yadong Huang, MD, PhD

This research comes at a time of renewed focus on Alzheimers disease, which currently afflicts 5.4 million people in the United States alone a figure expected to nearly triple by 2050. Yet thereare no approved medications to prevent or reverse the progression of this debilitating disease.

In findings appearing online today in Cell Stem Cell, researchers in the laboratory of Gladstone Investigator Yadong Huang, MD, PhD, describe how they transferred a single gene called Sox2 into both mouse and human skin cells. Within days the skin cells transformed into early-stage brain stem cells, also called induced neural stem cells (iNSCs). These iNSCs began to self-renew, soon maturing into neurons capable of transmitting electrical signals. Within a month, the neurons had developed into neural networks.

Many drug candidates especially those developed for neurodegenerative diseases fail in clinical trials because current models dont accurately predict the drugs effects on the human brain, said Huang, who is also an associate professor of neurology at UCSF. Human neurons derived from reengineered skin cells could help assess the efficacy and safety of these drugs, thereby reducing risks and resources associated with human trials.

Huangs findings build on the work of other Gladstone scientists, starting with Gladstone Investigator, Shinya Yamanaka, MD, PhD. In 2007, Yamanaka used four genetic factors to turn adult human skin cells into cells that act like embryonic stem cells called induced pluripotent stem cells.

Also known as iPS cells, these cells can become virtually any cell type in the human body just like embryonic stem cells. Then last year, Gladstone Senior Investigator Sheng Ding, PhD, announced that he had used a combination of small molecules and genetic factors to transform skin cells directly into neural stem cells. Today, Huang takes a new tack by using one genetic factor Sox2 to directly reprogram one cell type into another without reverting to the pluripotent state.

Avoiding the pluripotent state as Drs. Ding and Huang have done is one approach to avoiding the potential danger that rogue iPS cells might develop into a tumor if used to replace or repair damaged organs or tissue.

Instead we saw the reprogrammed cells integrate into the mouses brain and not a single tumor developed.

This research has also revealed the precise role of Sox2 as a master regulator that controls the identity of neural stem cells. In the future, Huang and his team hope to identify similar regulators that guide the development of specific neural progenitors and subtypes of neurons in the brain.

For the first time, scientists at Gladstone Institute have changed skin cells, imbued with a single genetic factor, into cells that can become a group of interconnecting, functional brain cells. The findings show that there may be options in combating neurological conditions. This transformation of cells would pave the way for better methods in testing drugs for neurodegenerative conditions like Alzheimers disease.

The research follows increased interest in Alzheimers disease. Currently, the disorder affects 4.5 million people in the U.S. and, by 2050, the number will have tripled. There are no medications to prevent or reverse Alzheimers Disease at this time.

The findings are published online at Cell Stem Cell and describe how the team of researchers transfer a single cell, known as Sox2, into mouse and human skin cells. Shortly, the skin cells became early-stage brain stem cells called induced neural stem cells (INSCs). The INSCs were able to self-renew and transmit electrical signals. The neurons were able to become neural networks within a month.

Many drug candidates especially those developed for neurodegenerative diseases fail in clinical trials because current models dont accurately predict the drugs effects on the human brain, commented Gladstone Investigation Dr. Yadong Huang, who is also an associate professor of neurology at the University of California, San Francisco (UCSF), in a prepared statement. Human neuronsderived from reengineered skin cellscould help assess the efficacy and safety of these drugs, thereby reducing risks and resources associated with human trials.

Huangs study was based off work done by Gladstone Investigator Dr. Shinya Yamanaka. Yanaka had four genetic factors become adult human skin cells then into embryonic stem cells, otherwise known as induced pluripotent stem cells (iPS cells). The cells can become almost any type of cell in the body. As well, last year, Gladstone Senior Investigator Dr. Sheng Ding found a combination of small molecules and genetic factors that could change skin cells into neural stem cells. These days, Huang uses one genetic factor, Sox2, to directly reprogram cell types without having to resort back to a pluripotent state.

We wanted to see whether these newly generated neurons could result in tumor growth after transplanting them into mouse brains, explained Karen Ring, UCSF Biomedical Sciences graduate student and the papers lead author, in the statement. Instead we saw the reprogrammed cells integrate into the mouses brainand not a single tumor developed.

The findings of the project have shown that Sox2 acts as a master regulator that maintains the identity of neural stem cells. In the future, Huang and his fellow researchers hope that they can identify similar regulators that can help the development of particular neural progenitors and subtypes of neurons in the brain.

If we can pinpoint which genes control the development of each neuron type, we can generate them in the petri dish from a single sample of human skin cells, noted Huang. We could then test drugs that affect different neuron typessuch as those involved in Parkinsons diseasehelping us to put drug development for neurodegenerative diseases on the fast track.

A single genetic tweak is all that is needed to turn ordinary skin cells into functioning brain cells, scientists have shown

A single genetic tweak is all that is needed to turn ordinary skin cells into functioning brain cells, scientists have shown.

The research could help to treat Alzheimers, Parkinsons and other brain diseases.

Working in the laboratory, US scientists transferred a single gene called Sox2 into both mouse and human skin cells.

Within days the cells transformed themselves into early-stage brain stem cells.

These induced neural stem cells (iNSCs) then began to self-renew and mature, eventually becoming neurons capable of transmitting electrical signals.

In less than a month the cells had developed neural networks. Transplanted into mouse brains, they functioned without any adverse side effects, such as tumour growth.

Lead researcher Dr Yadong Huang, from the Gladstone Institutes in San Francisco, California, said: Many drug candidates, especially those developed for neurodegenerative diseases, fail in clinical trials because current models dont accurately predict the drugs effects on the human brain.

A unique form of carbon dating, made possible by the Cold War, suggests that new neurons rarely survive in the human olfactory bulb after birth

The human body is a tireless gardener, growing new cells throughout life in many organsin the skin, blood, bones and intestines. Until the 1980s most scientists thought that brain cells were the exception: the neurons you are born with are the neurons you have for life. In the past three decades, however, researchers have discovered hints that the human brain produces new neurons after birth in two places: the hippocampusa region important for memoryand the walls of fluid-filled cavities called ventricles, from which stem cells migrate to the olfactory bulb, a knob of brain tissue behind the eyes that processes smell. Studies have clearly demonstrated that such migration happens in mice long after birth and that human infants generate new neurons. But the evidence that similar neurogenesis persists in the adult human brain is mixed and highly contested.

A new study relying on a unique form of carbon dating suggests that neurons born during adulthood rarely if ever weave themselves into the olfactory bulb's circuitry. In other words, peopleunlike other mammalsdo not replenish their olfactory bulb neurons, which might be explained by how little most of us rely on our sense of smell. Although the new research casts doubt on the renewal of olfactory bulb neurons in the adult human brain, many neuroscientists are far from ready to end the debate.

In preparation for the new study, Olaf Bergmann and Jonas Frisn of the Karolinska Institute in Stockholm and their colleagues acquired 14 frozen olfactory bulbs from autopsies performed between 2005 and 2011 at the institute's Department of Forensic Medicine. To determine whether the neurons were younger than the people they came fromwhich would mean the cells were generated after birththe researchers needed to isolate the cells' DNA. First, they dissolved the brain tissue into a kind of soup, which they spun at high speeds so that the dense cell bodies and nuclei containing DNA sank to the bottom of the flasks. Using Y-shaped proteins called antibodies, which were hitched to fluorescent markers, the researchers tagged nuclei from both neurons and from glia, non-neuronal brain cells. After a laser-equipped cell-sorting machine identified and separated the nuclei, the researchers isolated and purified the DNA within.

Skin cells reprogrammed into brain cells

A team of scientists has discovered what could be a novel source for researching and potentially treating Alzheimer's disease and other conditions involving the destruction of brain cells.

Researchers at the University of California San Francisco-affiliated Gladstone Institutes converted skin cells from mice and humans into brain stem cells with the use of a protein called Sox2. Using only this protein to transform the skin cells into neuron stem cells is unusual. Normally, the conversion process is much more complex.

Neuron stem cells are cells that can be changed into the nerve cells and the cells that support them in the brain. The neuronal stem cells formed in this study are unique because they were prepared in a way the prevented them from becoming tumors, which is what often happens as stem cells differentiate, explained David Teplow, professor of neurology and director of the Easton Center for Alzheimer's Disease Research at UCLA. Teplow was not involved in the study, but is familiar with this type of research.

These immature brain stem cells then developed into different types of functional brain cells, which were eventually able to be integrated into mouse brains.

The idea that these cells can become fully functioning brain tissue is significant, the authors explained, because by becoming part of the brain, the cells can replace the cells killed off by the disease process.

These cells also offer a potential way to learn about the mechanisms behind neurodegenerative disorders as well as lead to research into new drugs, explained Dr. Yadong Huang, a study co-author and associate investigator at the Gladstone Institute of Neurological Disease.

"The next step is, we are trying to get these skin cells from patients with this disease so we can reprogram and convert the diseased cells into these neuron stem cells and develop those into neurons in culture," he said.

After that, researchers can study how these diseases develop based on what's observed in culture dishes.

"It's really hard to get neurons from human brains for research, and now, we can generate them," Huang said. "Secondly, we can do some drug screening. If we have patient-specific neurons in culture, we can test some or develop some drugs to see how they work on these neurons."

Skin Cells Turned Into Brain Cells

MADISON, Wis., June 7, 2012 /PRNewswire/ --Cellular Dynamics International, Inc. (CDI), the world's largest commercial producer of human induced pluripotent stem (iPS) cell lines and tissue cells, today announced the launch of its MyCell Services. These services include novel iPS cell line reprogramming, genetic engineering and differentiation of iPS cells into commercially available iCell terminal tissue cells (for example, heart or nerve cells).

"CDI's mission is to be the top developer and manufacturer of standardized human cells in high quantity, quality and purity and to make these cells widely available to the research community. Our MyCell Services provide researchers with unprecedented access to the full diversity of human cellular biology," said Bob Palay, CDI Chief Executive Officer. "The launch of MyCell Services furthers CDI founder and stem cell pioneer Jamie Thomson's vision to enable scientists worldwide to easily access the power of iPSC technology, thus driving breakthroughs in human health."

Over the past 2 years, CDI has launched iCell Cardiomyocytes, iCell Neurons and iCell Endothelial Cells for human biology and drug discovery research. MyCell Services leverage CDI's prior investment in building an industrial manufacturing platform that can handle the parallel production of multiple iPSC lines and tissue cells, manufacturing billions of cells daily.

Chris Parker, CDI Chief Commercial Officer, commented, "Not all studies requiring human cells can be accomplished by using cells from a limited set of normal, healthy donors. Researchers may need iPS cells or tissue cells derived from specific ethnic or disease populations, and MyCell Services enable them to take advantage of our deep stem cell expertise and robust industrial manufacturing pipeline to do so. Previously, scientists had to create and differentiate iPS cells themselves. Such activities consume significant laboratory time and resources, both of which could be better applied to conducting experiments that help us better understand human biology. CDI's MyCell Services enable scientists to re-direct those resources back to their experiments."

CDI pioneered the technique to create iPS cells from small amounts of peripheral blood, although iPS cells can be created from other tissue types as well. Additionally, CDI's episomal reprogramming method is "footprint-free," meaning no foreign DNA is integrated into the genome of the reprogrammed cells, alleviating safety concerns over the possible use of iPS cells in therapeutic settings. These techniques have been optimized for manufacture of over 2 billion human iPS cells a day, and differentiated cells at commercial scale with high quality and purity to match the research needs.

Modeling Genetic Diversity

CDI has several projects already underway using MyCell Services to model genetic diversity of human biology. The Medical College of Wisconsin and CDI received a $6.3M research grant from the National Heart, Lung, and Blood Institute (NHLBI), announced July 2011, for which CDI's MyCell Services will reprogram an unprecedented 250 iPS cell lines from blood samples collected from Caucasian and African-American families in the Hypertension Genetic Epidemiology Network (HyperGEN) study. In addition, MyCell Services will differentiate these iPS cells into heart cells to investigate the genetic mechanisms underlying Left Ventricular Hypertrophy, an increase of the size and weight of the heart that is a major risk factor for heart disease and heart failure.

Researchers are also using CDI's MyCell Services to generate iPS cells and liver cells from individuals with drug induced liver injury (DILI), toward an eventual goal of identifying genetic factors linked to idiosyncratic liver toxicity. "The most problematic adverse drug event is sudden and severe liver toxicity that may occur in less than one in one thousand patients treated with a new drug, and thus may not become evident until the drug is marketed. This type of liver toxicity is not predicted well by usual preclinical testing, including screening in liver cultures derived from random human donors," said Paul B. Watkins, M.D., director of with The Hamner - University of North Carolina Institute for Drug Safety Sciences. "The ability to use iPS cell technology to prepare liver cultures from patients who have actually experienced drug-induced liver injury, and for whom we have extensive genetic information, represents a potential revolution in understanding and predicting this liability."

Screening Human Disease

While most diseases are multi-systemic, focus typically centers on only one organ system. For example, congenital muscular dystrophy (CMD) is a group of rare genetic diseases with a focus on skeletal muscle, yet other systems, including heart, eye, brain, diaphragm and skin, can be involved. Understanding the molecular mechanisms underlying complex disease phenotypes requires access to multiple tissue types from a single patient. While some systems are readily accessible for taking a biopsy sample, for example skin, other organs are not.

SAN DIEGO, CA--(Marketwire -06/07/12)- Bio-Matrix Scientific Group, Inc. (BMSN) (BMSN) announced today that its wholly owned subsidiary Regen BioPharma, Inc. has executed an exclusive option agreement which grants Regen BioPharma an option to license Patent #6,821,513 which patents methods of stimulating blood production in patients with deficient stem cells. The patent, as well as data licensed with the patent, covers methods of stimulating the bone marrow to generate new blood cells. The patent and option agreement are disclosed in the Company's most recent 8K filed with the US Securities and Exchange Commission on June 6, 2012.

"The technology has broad applicability to help cancer patients recover faster following chemotherapy, as well as for recipients of bone marrow and cord blood transplants. Currently, new blood cell production is stimulated by expensive drugs such as Neupogen and Neulasta which replicate the body's growth factors but can cause side effects and rely upon the diminished recuperative powers of an immune compromised patient," stated J. Christopher Mizer, President of Regen BioPharma.

David Koos, Chairman & CEO of Bio-Matrix Scientific Group, added, "We are excited to get this therapy into the clinic. Based on peer-reviewed published animal data, it has the potential to restore immune function faster and more effectively than the existing standard of care."

The licensed technology covers the use of a naturally-occurring cell type for stimulation of bone marrow stem cells. By utilizing cells as opposed to drugs, Regen BioPharma believes it possesses a substantial advantage to existing approaches in terms of safety and economics of production. Currently the market for growth factors that stimulate blood making stem cells is more than $4.84 billion per year (www.wikinvest.com/stock/Amgen).

It's always troubling to see a misunderstanding concerning a recent scientific discovery. The latest concerns an Israeli team of scientists, led by Lior Gepstein, that converted skin cells from two patients with heart attack into stem cells and then heart cells.

SourceFed, one of my favorite channels on YouTube, proclaimed that Gepstein's study means that a cure for heart disease is "10, 15 years out." Similar statements were also circulated by The Guardian, The Los Angeles Times, CBS News, and others.

However, the claims that SourceFed and other news outlets have made are not true. If anything, the field of heart regeneration is moving away from what the study did. If there is a cure for heart attack in 10 to 15 years, it will not be because of this study.

Generating stem cells from skin cells is relatively old news. This feat was first performed in 2006 for mice (2007 for humans) concurrently by two teams of scientists led by Shinya Yamanaka in Japan and James Thomson in the United States, respectively. Since then, the technology has evolved so fast that generating heart cells from stem cells is truly nothing new.

Stem cells often differentiate into heart cells, or cardiomyocytes, without much technical intervention. Even I, a mere undergraduate student, have generated beating heart cells several times without much trouble, from mice and rat skin cells. And I'm not even in the field of heart regeneration. I work with stem cells in neurobiology.

The technique to generate heart cells from skin-derived stem cells (or induced pluripotent stem cells) has existed for a long time. After a brief search on Google Scholar, I found a paper published in 2008 detailing how to generate heart cells from skin cells. This may not seem like a long time ago, but in the stem-cell world, that's almost an eon.

So if we have been able to generate heart cells for such a long time, why has no one actually successfully transplanted heart cells into patients? One of the reasons is that there are so many different problems with not only transplanting heart cells onto a beating heart but also with the induced pluripotent stem cells that are derived from skin cells.

When a heart is damaged, scar tissues grow over the damaged part of the heart. The scar tissue does not function like regular heart cells. Instead of beating, the scar tissue just sits there, not doing anything and getting in the way of the beating heart. It's just like a scab on your arm from a scrape. The only difference is that the scab eventually comes off, because your skin is constantly making new cells, but the scar on your heart doesn't, because heart cells rarely regenerate, if at all.

Transplanting new heart cells without removing the scars is like putting a new layer of skin over the old scab and expecting the scab to go away. The old scab doesn't go away. More likely, the transplanted tissue will just die off.

As a result, instead of trying to transplant new tissue, the field of heart regeneration is now trying to transform the cells in scar tissue into beating heart cells. Though there are also problems with this new direction, it opens up ways of solving a whole host of other problems that plague heart-cell transplantation.

A local veterinary clinic recently added a cuttingedge treatment.

Dr. Tina Gemeinhardt, owner of Tsawwassen Animal Hospital, is excited to be offering stem cell therapy to animals suffering from arthritis and joint issues.

"I'm excited about trying to bring some relief to dogs that are living in pain," she said.

The therapy, which uses stem cells harvested from fat that is surgically removed from the dog, is, in most cases, able to offer relief from the pain and stiffness associated with

Gemeinhardt said once it's determined the therapy is the right course of treatment for an animal, body fat is surgically removed and sent to a lab in California where the stem cells are harvested. The harvested stem cells are then sent back to the vet clinic within 48 hours and injected into the joints in question.

Gemeinhardt, who added the treatment to the clinic's list of services earlier this year, said it's not quite clear exactly how the stem cells work.

"Stem cells seem to inherently know what needs to be done in that area," she said.

The treatment is not a cure-all - the arthritis is still there but the symptoms are lessened - and it does not work instantly. The vet said most animals start to notice a difference in a month or so, and some might require follow up injections.

She said about 85 per cent of animals receiving stem cell therapy have had a beneficial response, while 15 per cent saw no response.

Beatrice, a seven-yearold chow chow, has seen remarkable results. Owner Rose McClelland said Beatrice had been having problems with arthritis in her hips for years and medication wasn't working any more.

A drug that stops the body from rejecting bone marrow transplants in cancer patients could be ready for human trials in three years time.

The latest development comes after more than a decade of research unlocking the function of a protein called perforin, which kills rogue cells in the body.

Australian researchers involved in unravelling perforin's molecular structure, a discovery published in the journal Nature in 2010, are now working towards developing a safe drug to block the protein.

Perforin plays a key role in the body's immune response by punching holes in, and killing, cells which have been hijacked by viruses or cancer to rid the body of disease.

However, the protein is problematic for bone marrow transplant patients because it can cause the body to reject the treatment.

For this reason, a project led by the Peter MacCallum Cancer Centre in Melbourne is developing a drug to inhibit the protein in bone marrow stem cell transplant patients to help their recovery.

The drug works in mouse models, but a $6.8 million grant from the UK's Wellcome Trust will allow the drug to be fine-tuned for human trials.

'In the mouse models we use, we know the inhibitors are effective,' project leader Professor Joe Trapani, executive director of cancer research at Peter Mac, told AAP.

'They actually help stem cells survive when they would otherwise be rejected.'

The Peter Mac team is working with New Zealand chemist Prof Bill Denny to refine the drug, along with Monash University and Queensland Institute of Medical Research scientists.
