Home Health News Mouse teeth shown to hold insight into future stem cell tissue regeneration

The use of stem cells throughout the years has been both a decisive topic and one that holds a lot of promise for potential medical therapy. They are essentially undifferentiated biological cells that havent yet been specialized for a specific purpose. The cells of your heart, stomach, and even your brain have all started out as stem cells, and it wasnt until some point during human development that biological processes channeled them to permanently becoming one type of cell. Scientists and researchers around the globe are always in search of the best way to learn about and harvest these valuable cells, and the latest reports suggest the teeth of rodents are an abundant source.

There are considered two main stem cell types in the body: one is from embryonic development when in the womb, and the other are adult stem cells that exist throughout the body. Harvesting embryonic stem cells has been controversial, as it often seen as unethical, but adult stem cellsfound in organs such as the bone marrow, blood vessel, and liver in mammalsis easier to obtain. Stomach linings, for example, require the constant shedding of their cell linings as the acid wears away at them, and having adult stems cells allows for quick replacement of these sloughed off cells.

Weve all seen mice before, and one of their defining characteristics are their front teeth. What most people arent aware of is that their front teeth, or incisors, constantly grow, as they rely on them to be consistently sharp for burrowing and self-defense, and of course, for eating away at your pantry food. As we grow older our teeth start to wear out, and in nature, once you dont have your teeth anymore, you die. As a result, mice and many other animals from elephants to some primates can grow their teeth continuously. Our labs objective is to learn the rules that let mouse incisors grow continuously to help us one day grow teeth in the lab, but also to help us identify general principles that could enable us to understand the processes of tissue renewal much more broadly, said UC San Franciscos Ophir Klein, MD, Ph.D., a professor of orofacial sciences in UCSFs School of Dentistry and of pediatrics in the School of Medicine.

While not all aspects of this process are fully understood just yet, as the exact signals triggering this process have yet to be identified. It, however, marks an advancement of knowledge in the field, and one that bodes well for the future of stem cell therapy. It may prove beneficial for tissue regeneration to treat everything from severe burns to growing entire organs from scratch.

WHAT: Rummage, bake and vendor sale to benefit area resident Trisha Suits who will be undergoing leukemia treatments at the Cleveland Clinic.

WHEN: From 9 a.m.-4 p.m. Friday and Saturday, May 5-6.

WHERE: Guilford Lake Ruritan Hall, state Route 172.

She was born weighing just a pound and eight ounces. But Trisha Suits is hardly a lightweight.

The courageous 30-year-old Lisbon resident, left virtually blind due to her premature birth, has taken on all comers throughout her life. Despite having only 2 percent vision in her right eye and none in her left, she has been a capable mom in helping to raise her son. She is a 2006 David Anderson High School graduate. Remarkably, she ran as a member of the cross-country team, memorizing her routes. Just putting one foot in front of the other, Trisha quipped, saying never fell. She later served as a Blue Devils assistant coach.

Now she is confronting her biggest challenge. She has been diagnosed with a complex form of leukemia and will be undergoing bone marrow and stem cell transplants at the Cleveland Clinic. Due to ongoing treatments, she will be required to remain in the hospital for six weeks. Then she will need to stay at a nearby housing complex for another 100 days.

Trisha was diagnosed in early March, after passing out from severe blood loss. She spent a month in the Cleveland Clinic getting chemotherapy. But due to genetic mutations, she needs bone marrow and stem cell transplants to combat acute myeloid leukemia a type of cancer that starts in the blood-forming cells of marrow.

According to her aunt, Melody Hobbs of Salem, her lengthy stay at the housing complex the Transplant House of Cleveland will cost about $75 per day for just the lodging. A donor has been found. Transplant treatments are expected to begin May 11.

To help offset the costs, a combination rummage, bake and vendor sale for Trisha will be held this Friday and Saturday, May 5-6, from 9 a.m. to 4 p.m. each day at the Guilford Ruritans Hall off of state Route 172.

We just need people to come, Hobbs said. We are trying to raise awareness to get more people out there. All the money raised will pay for Trishas lodging and transportation.

Trishas ordeal is and will continue to be grueling. Admittedly, she gets bitter, angry and frustrated. The uncertainty is overwhelming.

The really hard part of it will be being in Cleveland away from her son and family, said Hobbs.

Indeed, Trishas said her hobby is being the best mom she can be for her son. Six-year-old Landon is a McKinley Elementary School student.

I love my mommy, he offered. Its not just my moms fight, its our fight.

Trisha and her son lives with her parents, Rick Joy and Alice Loy. Her sister, Summer Burkholder, is a co-organizer of this weekends benefit.

The transplants offer a possible cure. Without them, it would be dire.

God only gives me what I can handle, said Trisha who has spent her entire life combating challenges. But I am scared about what this is going to do to my body.

An artist's impression of a reprogrammed stem cell.

Ella Marushchenko

In a curious confluence of the information technology industrys favourite word and scientists weakness for punning acronyms, researchers in St Louis, Missouri, in the US, have created what have been dubbed SMART cells.

SMART, in this case, stands for Stem cells Modified for Autonomous Regenerative Therapy, and their creation by a team based jointly at the Washington University School of Medicine and Shriners Hospital for Children promises a novel treatment for arthritis and other chronic conditions.

The team, led by Washington Universitys Farshid Guilak, reasoned that much of the pain and discomfort endured by arthritis suffers arises from inflammation caused by damaged cartilage. Reducing that inflammation, therefore, is an important therapeutic outcome.

To test this the team used mice. First, they harvested skin cells from tails, then turned them into stem cells. Next, using CRISPR gene-editing technology they excised a gene associated with inducing inflammation and replaced it with one that dampens it.

The resulting cells were then induced to grow into cartilage cells in cultures. The tissue thus produced was found to be free of inflammation.

In a clever move perhaps making the stem cells doubly smart Guilak and his colleagues further modified the stem cells so that they would light up when experiencing inflammation, making them easy to spot.

The research is published in in the journal Stem Cell Reports, and includes the news that research has now commenced using live mice.

Should the SMART cells eventually be found to be a viable avenue for human treatment, the results promise to be both more effective and better focused than existing arthritis drugs.

Pharmacological approaches to arthritis treatment mainly target the inflammation-promoting molecule called tumor necrosis factor alpha. The problem, however, is that they all do so on a system-wide basis, weakening the immune system and making patients more liable to infection.

We want to use our gene-editing technology as a way to deliver targeted therapy in response to localised inflammation in a joint, as opposed to current drug therapies that can interfere with the inflammatory response through the entire body, says Guilak.

Study co-author Jonathan Brunger says the most pleasing aspect of the teams CRISPR-based approach is that it effectively highjacks the inflammatory pathway and turns it into a protective mechanism.

The ability to build living tissues from smart stem cells that precisely respond to their environment opens up exciting possibilities for investigation in regenerative medicine, he adds.

Irish cardiologists have found a way to repair damaged cardiac muscle and reduce the risk of future heart failure by injecting a growth promoter into the hearts of heart attack sufferers. Photograph: Getty Images

A team of Irish cardiologists have shown that injecting an insulin-like growth promoter into the hearts of patients who have suffered a severe heart attack can repair damaged cardiac muscle and reduce the risk of future heart failure.

Prof Noel Caplice, Chair of Cardiovascular Sciences at University College Cork, and his cardiologist colleagues at Cork University Hospital successfully tested the growth factor in a clinical trial involving 47 patients who presented at the Cork hospital after experiencing heart attacks.

Prof Caplice said 20 per cent of people who suffer heart attacks have severe ongoing difficulties because of lasting damage to heart muscle even after the best current therapies.

After you have a heart attack, regardless whether you treat it with a stent or whatever, about 20 per cent of patients go on to have poor remodelling heart muscle cells die, you get scar tissue forming and the heart tends to expand and dilates, a bit like a balloon, and you get thinned-out heart muscle.

With that poor remodelling of the heart, the heart as a structure performs much worse, it doesnt work very well in terms of its function that leads to a substantial number of those patients going on to suffer heart failure with an increased risk of death, he said.

However, 10 years ago, Prof Caplice and his team began looking at using stem cells as a means of repairing damaged tissue and they found a protein within the stem cells, IGF 1, previously used to treat congenital dwarfism and growth problems, was leading to the repair of damaged heart muscle.

IGF 1 acts differently to insulin in that it acts on a different receptor in the body and when we inject it, it gets into the heart tissue and it basically stimulates receptors on the surface of the cardiac cells and in about 30 minutes, it sends a survival signal to the heart muscles cells, he said.

What we discovered from the stem cell study was that the concentration of the factor was extremely low so what we did was that we took the purified factor and in studies with pigs we injected them in the context of a heart attack and we found these major remodelling benefits.

Those animal tests were funded by Science Foundation Ireland but four years ago the Health Research Board came on board and the two bodies provided a 1 million grant to allow the treatment be trialled on humans.

Working with a 25-strong team incorporating cardiologists, radiologists, MRI specialists and nurses, Prof Caplice was able to incorporate the IGF 1 trials into the treatment of patients attending CUH with severe cardiac events and over the past three years have trialled it on 47 patients.

Patients received two different low-dose preparations of insulin-like growth factor or placebo in a randomised double-blinded clinical trial, with results showing those who received the higher dose had improved remodelling of their heart muscle in the two-month follow-up after their heart attack.

Prof Caplice said the CUH trials, the results of which he will present at a European Society of Cardiology conference in Paris on Saturday, were the first use of IGF 1 in human hearts and part of its attractiveness was its low dosage ensuring minimal side effects while improving cardiac structure.

Among the beneficiaries was John Nolan from New Ross who suffered a heart attack in December 2014. I feel I was blessed to be asked to be involved; I had confidence that good would come from it, in terms of how they explained it to me. Looking back on it now, I feel it was the right choice.

For Prof Caplice, the challenge now is to expand the trials to several hundred patients possibly across different countries and different healthcare systems to see if the IGF 1 treatment is globally applicable which, if proven to be the case, could lead to regulatory approval within five years.

Irish researchers 'cut risk of heart failure with one injection' - Irish Times

Few things could start out so simple and yet maybe lead you to save a life. But one woman's firsthand experience led precisely down that road, and now she's getting more people on board.

Be the Match is a program offering free kits for people to submit their DNA through mouth swabs to see if they might one day be a match to donate to someone with blood cancers or other blood-based diseases.

And getting that opportunity is about to become even easier for those in the Roaring Fork Valley this coming First Friday (May 5) and then on Dandelion Day (May 13) in Carbondale.

Erica Borum, who works as a civil engineer for the White River National Forest, is setting up a Be the Match booth at these events, where she'll have registry kits with mouth swabs ready to be used and sent off.

This first step is simple. If you're between 18 and 44 you can participate, but this first step doesn't mean that you're automatically going to be donating to someone.

Your mouth swab puts you on a DNA registry. Once your DNA is on the list, that information is available to doctors looking for donors who match with patients in need for stem cells or bone marrow.

According to Be the Match, each year about 14,000 patients are down to one option for a cure: a transplant from someone outside their family.

Borum is pushing this effort in Carbondale after her own experience a little more than a year ago donating to a man with Hodgkin's lymphoma. She wants to give people this opportunity by bringing the kits to them, but she's also on a mission to demystify the process.

"When people are first addressed with it, it's strange and weird and not something that would be of interest," she said. "I'd like to help make it not so foreign."

Borum first heard about this donation process through a friend, who knew of someone needing a bone marrow transplant for leukemia. The patient was down to her last option, but in the end the procedure worked out for her.

Borum got online and started doing her research on the organization Be the Match.

The chances that you'll be selected are actually quite slim. This isn't as simple as finding a person with matching blood type. Because doctors are looking for someone with highly specific blood markers and other characteristics to give the patient the best shot possible for a good transfer, only about one in 430 people end up being suitable match, she said.

There are two types of transfers: a transfer of peripheral blood stem cells or a bone marrow transplant. Ultimately, the patient's doctor choses which route to go, so donors need to be willing to do either.

Donating blood stem cells, which is what Borum did, is a bit like an extended blood draw.

"The first thing to know is my phobia is needles," said Borum. "But knowing that phobias are completely illogical, I went ahead and sent off my swabs. And there wasn't a great chance that I would be a match anyway.

"The prospect of going through a process that's a little uncomfortable for the benefit of saving someone, it's kind of overwhelming," she said. "To be honest, I didn't give it a second consideration, despite the phobia."

She joined the registry in 2013. The mouth swab process took only about 10 minutes, she said.

A little more than two years later, Borum got that call that she was a preliminary match. Did she want to proceed with the process?

Even agreeing at this point isn't the final say in whether you end up donating. First, Borum had her blood drawn and sent off to reinforce that, yes, she was a match. And after that was confirmed she had to get a physical and undergo some pathogen testing, a chest X-ray and some additional testing to make sure she was healthy.

During this process, the identity of the patient is guarded. All Borum was told was that the patient was a 56-year-old man with Hodgkin's lymphoma.

From there it was a repeated process of "test and we'll let you know, test and we'll let you know," she said.

'ONE POKE AT A TIME'

And as each of those came back good, they check to see if you want to proceed. The donor can pull out at any time. But while the donor is going through this process, the patient is going through a parallel preparation of intensive chemotherapy trying to kill as much of the cancer as possible before the transplant.

This is a critical stage for the patient, and if the donor opts out now, it could be life-threatening for the patient, she said.

"I took it one needle poke at a time."

Leading up to the final blood draw, Borum was given several injections of a drug to boost her cell count to help doctors withdraw the stem cells they were looking for.

On the long end, physicians say the blood draw process could take up to six hours. That was their prediction for Borum, who is more petite. During that draw, they run the first samples to a lab to confirm they're getting the right concentration. Borum's body reacted well to the blood cell-boosting drug, and the final process ended up only taking four hours.

To explain her motivation to go through with this procedure, Borum said it's part of her spiritual practice.

"I did it as part of the practice, and recognizing that a lot of things we do are self-referential and self-serving. And I don't think there's a ton of benefit in that, for myself and for others.

"I think the quote from the Dalai Lama goes: If you want others to be happy, have compassion; if you want to be happy, have compassion.

"And it's all a matter of statistics. If there are more people in the registry, it's more likely someone will have a match. If I can benefit one person, it's little effort on my end to try to boost the numbers."

Because of the statistically low chances of finding a match, getting more people on the registry is essential. And the first month or two after the final transplant is a time critical to find out whether their new blood stem cells are working. This doesn't always have a happy ending, said Borum.

But in her case, it did.

BUILDING A BOND

Her transfer was a little more than a year ago. About two months afterward she got word that her cells were successfully making the patient's blood and he had no sign of cancer cells. The patient, who Borum learned lives in New York, sent her a thank you card a few months later, and recently they've exchanged emails.

And in those exchanges, she got her first glimpses into his life.

"I am a husband of 28 years and the father of two boys and was facing a difficult future," he wrote in April of last year. "I am overwhelmed beyond words with this gift you have given me. Please know that I will live the rest of my life with the warmth of your generosity and will do my best to extend it to others in need."

"His email said that he's now been healthy for one year and two months," said Borum. He's also offered to come to Colorado to meet Borum and thank her in person.

His sickness had taken him to a point where walking was a very difficult task, but now he's running again.

The whole process, they say, is about 20 to 30 hours of your time, usually spread over about four to six weeks, according to Be the Match.

"I think that's a small sacrifice to potentially save someone," said Borum.

The patient in this case wasn't available for this article but for pretty much the best reason ever.

Borum said that after being too sick for so long, he was finally leaving for a long-awaited vacation.

A study from scientists at the Francis Crick Institute, the Max-Delbrck Center for Molecular Medicine, Berlin and the University of Edinburgh sheds new light on the cells that form spinal cord, muscle and bone tissue in mammalian embryos.

This discovery paves the way for generating these tissues from stem cells in the laboratory and could lead to new ways of studying degenerative conditions such as motor neuron disease and muscular dystrophy.

In embryos, the spinal cord, muscle and skeleton are produced from a group of cells called NMPs (neuro-mesodermal progenitors). These cells are few in number and exist only for a short time in embryos, despite giving rise to many tissues in the body. Their scarcity and inaccessibility has made studying NMPs challenging. Now, by using the latest molecular techniques, the research team has for the first time deciphered gene activity in NMPs. They used an advanced technique called single-cell transcriptional profiling, which analyses individual cells to provide a detailed picture of gene activity in every cell.

The technique allowed the team to establish a molecular signature of NMPs and to show that NMPs produced from stem cells in petri dishes in the laboratory closely resemble those found in embryos. This enabled the team to use lab-grown NMPs to learn more about these cells and how they make spinal cord, muscle and bone tissue. By manipulating the cells in petri dishes and testing the function of specific genes, the researchers re-constructed the regulatory mechanism and formulated a mathematical model that explains how NMPs produce the appropriate amounts of spinal cord and musculoskeletal cells.

Dr James Briscoe, who led the research from the Francis Crick Institute said:

"For embryonic development to progress smoothly, NMPs must make the right types of cells, in the right numbers at the right time. Understanding how cells such as NMPs make decisions is therefore central to understanding embryonic development. Single cell profiling techniques, including the ones we used in this study, are giving us unprecedented insight into this problem and offering a new and fascinating view of how embryos produce the different tissues that make up adults."

First author of the study Dr Mina Gouti, from the Max-Delbrck Center for Molecular Medicine, Berlin said:

"Improving our understanding of NMPs doesn't only answer an important developmental biology question but also holds great promise for regenerative medicine. It takes us a step closer to being able to use tissue from patients with diseases that affect muscles and motor neurons in order to study the causes and progress of these diseases. Being able to grow cells in the laboratory that faithfully resemble those found in the body is crucial for this."

Whether your adult mesenchymal stem cells come from bone marrow or from fat probably does not make a difference in terms of clinical results. Although some centers claim that bone marrow derived cells are superior to fat derived cells, there is no evidence to substantiate that. Recent studies show that fat derived cells make bone tissue much better than the bone marrow derived cells. Some studies are showing different outcomes but it is important to realize that these studies are all done in petri dishes and may not relate to living organism. Also, it is important that one is not mislead in some marketing materials by the word bone in bone marrow, possibly implying that since this is an orthopedic source it must be better for treating orthopedic conditions such as cartilage regeneration. In fact, the bone marrow is part of the reticulo-endothelial system (makes blood cells) and just happens to be found in the center of bone. The truth is, both bone marrow derived and stromal (from fat) derived stem cells are both effective for regenerative therapy and both have the potential to differentiate into mature functional cartilage. However, stem cells from fat are 100 to 1000 times more plentiful and this makes same day procedures (allowed in the US) much more effective with fat derived cells. The higher numbers of cells in fat leads to better clinical outcomes. Also, the quality of bone marrow declines with age and it has less numbers of cells and less healthy cells compared to the fat. The diminution in quantity and quality of bone marrow cells related to age and chronic illness is well documented. Last but not least, the ease of removing fat from under the skin using a mini-liposuction under local anesthetic is much less invasive and MUCH LESS painful than undergoing bone marrow aspiration to obtain bone marrow cells.

Researchers at University of California, Irvine (UCI) have developed a method that can transform human skin cells into brain cells. With this amazing feat, scientists may be able to better understand what role inflammation plays in the progression of Alzheimers disease. And this knowledge could lay the groundwork towards developing more effective treatments and therapies to manage the condition.

Before this breakthrough, scientists relied mostly on mice microglia to study the immunology of Alzheimers. Microglia sometimes referred to as Hortega cells are a special kind of cell that can be found in the human brain and spinal cord. The primary role of these cells is to protect the brain and the spine from infections, disease and any invading microbe. They provide immune support for the entire central nervous system by removing dead cells, damaged cells and other debris.

Along this line, microglial cells also help keep healthy cells from degenerating managing inflammation as well as developing and maintaining the integrity of neural networks which is why they are believed to play a special role in delaying the progression of neurodegenerative conditions like Alzheimers.

While studying brain cells from mice is useful, studying the real thing is, of course, more preferable. And the method developed by the UCI team is a step in this direction.

Using skin cells donated by UCI Alzheimers Disease Research Center patients, the UCI team led by Edsel Abud, Mathew Blurton-Jones and Wayne Poon made use of a genetic process to reprogram the skin cells and turn them into induced pluripotent cells (iPSCs) adult cells that are modified to act like embryonic stem cells which can turn into any kind of cell or tissue. The iPSCs were then exposed to a series of differentiation factors which mimicked the developmental origin of microglia. This exposure resulted in cells that are pretty much like human microglial cells.

Instead of continuing to rely on mice microglial cells, scientists now have a more realistic model for studying human disease in order to develop new and better therapies. And they have now started on this new path. They are using the microglial-like cells in 3D brain models so they can study how these cells interact with other brain cells and understand how this interaction impacts the progression of Alzheimers and the development of other neurological conditions.

As explained by Professor Blurton-Jones in a statement they issued: Microglia play an important role in Alzheimers and other diseases of the central nervous system. Recent research has revealed that newly discovered Alzheimers-risk genes influence microglia behavior. Using these cells, we can understand the biology of these genes and test potential new therapies.

This latest breakthrough is once again proving how important stem cells are in helping understand biological processes, both under normal conditions and under disease-related conditions. Eventually, scientists are bound to stumble on that ultimate discovery that can hopefully be instrumental in combating diseases right at their source, so we can stop dealing with devastating diseases, especially those that affect the brain and threaten a persons life.

The study was recently published in the journal Neuron.

A quick glance at your calendar will reveal that we're now in 2017. 2017, you may recall, is the year when contraversial surgeon Sergio Canavero has promised to perform the world's first human head transplant.

But just how feasible is a human head transplant? Is it the stuff of science fiction, or does it have a basis in current sceintific thinking? Read on for everything you need to know about 2017 most alarming scientific development.

A human head transplant is exactly what it sounds like taking one living head and putting it onto a new body.

But actually, thats a little misleading. In real terms, its a body transplant, as the head will be gaining a new body to control. However, as the term whole body transplant is already used to mean transferring the brain between bodies, calling it a head transplant makes it clear that the whole head is to be switched, brain included.

Until recently, a head transplant seemed totally implausible, but the Italian scientist Dr Sergio Canavero believes its possible, and intends to conduct the first surgery in 2017.

Canavero outlines the procedure in detail here, but these are the basics of the process. Remember: dont try this at home, kids.

The donor body and the head to be attached are first cooled down to 12-15C to ensure that the cells last longer than a few minutes without oxygen. The tissue around the neck is then cut, with the major blood vessels linked with tiny tubes. The spinal cord on each party is then severed cleanly with an extremely sharp blade.

"Post coma, Canavero believes the patient would immediately be able to move, feel their face and even speak with the same voice."

At this point, the head is ready to be moved, and the two ends of the spinal cord are fused using a chemical called polyethylene glycol, encouraging the cells to mesh. This chemical has been shown to prompt the growth of spinal cord nerves in animals, although Canavero suggests that introducing stem cells or olfactory ensheathing cells into the spinal cord could also be tried.

After the muscles and blood supply are successfully connected, the patient is kept in a coma for a month to limit movement of the newly fused neck, while electrodes stimulate the spinal cord to strengthen its new connections.

Following the coma, Canavero anticipates that the patient would immediately be able to move, feel their face and even speak with the same voice. He believes physiotherapy would allow the patient to walk within a year.

He explains his suggested methods in the TED talk below.

Sceptical would be a nice way of putting it. Horrified would, in most cases, be more accurate.

Dr Hunt Batjer has attracted headlines for being particularly blunt: I would not wish this on anyone. I would not allow anyone to do it to me as there are a lot of things worse than death.

Dr Jerry Silver witnessed the 1970s monkey head transplant experiment more on which later and describes the procedure as bad science, adding that just to do the experiments is unethical. This is a particular blow to Canavero, as he states that Silvers own work in reconnecting rats spinal cords should give hope to the human head transplant. Silver dismisses this: To sever a head and even contemplate the possibility of gluing axons back properly across the lesion to their neighbours is pure and utter fantasy in my opinion.

Dr Chad Gordon, professor of plastic and reconstructive surgery and neurological surgery at Johns Hopkins University, agrees that Canaveros claims are scientifically implausible. He told BuzzFeed: Theres no way hes going to hook up somebodys brain to someones spinal cord and have them be functional.

On the conservative side, were about 100 years away from being able to figure this out, he continued. If hes saying two, and hes promising a living, breathing, talking, moving human being? Hes lying.

Dr Paul Myers, associate professor of biology at the University of Minnesota at Morris, puts it even more explicitly: This procedure will not work... Try it with monkeys first. But he cant: the result would be, at best, a shambling horror, an animal driven mad with pain and terror, crippled and whimpering, and a poor advertisement for his experiment. And most likely what hed have is a collection of corpses that suffered briefly before expiring.

Others wonder whether Canavero might simply be enjoying the limelight with a PR stunt, including Dr Arthur Caplan, director of ethics at the NYU Langone Medical Centre. Describing the doctor as nuts, he explained to CNN: Their bodies would end up being overwhelmed with different pathways and chemistry than theyre used to, and theyd go crazy.

"We'll probably see a head on a robot before we see it on [another] body," he told Live Science.

Dr John Adler of Stanford University's school of medicine is slightly more optimistic... but not much more. "Conceptually, much of this could work, but the most favourable outcome will be little more than a Christopher Reeve level of function," he told Newsweek.

Canavero is aware of this criticism, claiming that silently hes received a lot of support from the medical community. Of Dr Batjers comments that the surgery would be a fate worse than death, Canavero is scathing. Hes a vascular surgeon. A vascular surgeon of the brain, yes, but he knows nothing, he argued. How can you say such a thing? Its incredible.

"The world is moving, the critics are dwindling. Of course, there will always be critics. Science teaches us that when you propose something groundbreaking, you must be confronted by criticism. If no critics really step forward, you are saying nothing special," he told Medical News Today.

Dr Canavero also believes that the operation could essentially be used to revive the dead, if brains were suitably frozen and stored. In an interview with German magazine Ooom, Canavero said: "We will try to bring the first of the company's patients back to life, not in 100 years. As soon as the first human head transplant has taken place, i.e. no later than 2018, we will be able to attempt to reawaken the first frozen head.We are currently planning the world's first brain transplant, and I consider it realistic that we will be ready in three years at the latest."

No-one has ever attempted a human head transplant before, and attempts on animals have to put it charitably had limited success.

The photo above really does show a dog with two heads and its not a fake. This was the work of Soviet scientist Vladimir Demikhov, and for four days the hybrid of two dogs lived as normally as such a scientific horror could be expected to. Then they died.

Demikhov tried the experiment more than 24 times, but was unable to find a way of avoiding the dogs dying shortly after surgery. Although the results are horrifying to see, Demikhovs research did pave the way for human organ transplants.

"For four days this hybrid of two dogs lived as normally as such a scientific horror could be expected to. Then they died."

But back to the topic of head transplants. The first time a straight swap was successful, was by Dr Robert White, in an experiment on a rhesus monkey in 1970. I feel the need to qualify the word successful with quotation marks, because although the monkey did live, he didnt live very long. Eight days, to be exact, and as the spinal cord wasnt attached to its new body, the monkey was paralysed for its remaining days. However, it could indeed see, hear, smell and taste before the body rejected the foreign head.

According to Canavero in his paper on human head transplants, the monkey lived eight days and was, by all measures, normal, having suffered no complications. However, Dr Jerry Silver who worked in the same lab as Dr White has more haunting memories. He toldCBS: I remember that the head would wake up, the facial expressions looked like terrible pain and confusion and anxiety in the animal. The head will stay alive, but not very long. It was just awful. I dont think it should ever be done again.

More recently, Chinese doctor Xiaoping Ren claims to have conducted head transplants on more than 1,000 mice. The Wall Street Journal reports to have witnessed a mouse with a new head moving, breathing, looking around and drinking. But, crucially, none of these mice have lived longer than a few minutes.

Still, Dr Rens studies continue, and the latest reports are said to be promising, offering a possible answer to the risk of severe blood loss (or brain ischemia) during transplantation. The experimental method that we have described can allow for long-term survival, and thus assessment of transplant rejection and central nervous system recovery, bringing us one step closer to AHBR in man, the researchers wrote.

Ren himself has not ruled out taking part in the first human head transplant operation, according to the Daily Mail. "A human head transplant will be a new frontier in science. Some people say it is the last frontier in medicine. It is a very sensitive and very controversial subject but if we can translate it to clinical practice, we can save a lot of lives," he said.

"Many people say a head transplant is not ethical. But what is the essence of a person? A person is the brain not the body. The body is just an organ," he added.

In January 2016, Canavero told New Scientist that a head transplant had been successfully completed on a monkey in China, although details were sparse. "The monkey fully survived the procedure without any neurological injury of whatever kind," he said, although the article notes that the monkey only kept alive for 20 hours after the surgery for "ethical reasons," limiting its use as a comparison somewhat.

In September 2016, Canavero revealeda further trial of the head transplant on dogs.New Scientisthas seen video footage of a dog appearing to walk three weeks after its spinal cord was severed, with Canavero claiming that the outcome is the result of the same techniques he plans to use on Spiridonov next year.

However, speaking to a number of scientists for their view on the new evidence, New Scientistcould find few sceptics converted. "These papers do not support moving forward in humans," said Jerry Silver a neuroscientist at Cape Western Reserve University in Ohio.

"The dog is a case report, and you cant learn very much from a single animal without controls. They claim they cut the cervical cord 90 per cent but theres no evidence of that in the paper, just some crude pictures," added Silver.

You could say so, though Canavero doesn't see it quite like that. In fact, controversially he sees it more as a failure of other types of medicine, telling Medical News Today, "It will be about curing incurable neurological disorders for which other treatments have failed big time, so gene therapy,stem cells- they all just came to nothing. We have failed despite billions of dollars being poured into this sort of research."

"So actually, head transplant or body transplant, whatever your angle is, is actually a failure of medicine. It is not a brilliant success, a brilliant advancement to medical science. When you just haven't tackled biology, you don't know how to treat genes, you don't really understand, and you really need to resort to a body transplant, it means that you've failed. So this must not be construed as a success of medical research," he added.

A research misconduct investigation of a prominent stem cell lab by the Harvard Universityaffiliated Brigham and Womens Hospital (BWH) in Boston has led to a massive settlement with the U.S. government over allegations of fraudulently obtained federal grants. As Retraction Watch reports, BWH and its parent health care system have agreed to pay $10 million to resolve allegations that former BWH cardiac stem cell scientist Piero Anversa and former lab members Annarosa Leri and Jan Kajstura relied on manipulated and fabricated data in grant applications submitted to the U.S. National Institutes of Health (NIH).

A statement from the U.S. Attorneys Office for the District of Massachusetts released today notes that it was BWH itself that shared the allegations against Anversas lab with the government. The hospital had been conducting its own probe into the Anversa lab since at least 2014, when a retraction published in the journal Circulation revealed the ongoing investigation. The hospital has not yet released any findings.

In 2014, Anversa and Leri sued Harvard and BWHalong with BWH President Elizabeth Nabel and Gretchen Brodnicki, Harvards dean for faculty and research integrityfor launching and publicizing the investigation that they claimed wrongfully damaged their careers. In their complaint, they acknowledged fabricated data in the Circulation paper and altered figures in a 2011 paper for whichThe Lancethas published an expression of concern. But they claimed that Kajstura had altered data without their knowledge. (Anversa and Leris recent papers list their institution as Swiss Institute for Regenerative Medicine, Retraction Watch notes.)

In July 2015, a federal district court judge dismissed the lawsuit, ruling that the plaintiffs had to first air their grievances with the federal Office of Research Integrity, which handles misconduct investigations at NIH-funded labs.

Grant fraud cases against universities rarely involve research misconduct, and most are brought by whistleblowers who stand to claim a share of any returned funds. Despite the high penalty, BWH gets praise from the Department of Justice in todays announcement for self-disclosing the allegations and for taking steps to prevent future recurrences of such conduct.

But the result is confusing and potentially discouraging, says Ferric Fang, a microbiologist at the University of Washington in Seattle, who has published several analyses of retractions, misconduct, and the scientific enterprise. It sounds as if the researchers themselves were found to have engaged in improper practices, but the institution is on the hook for the settlement. The decision deserves greater clarification, he says, or it could discourage other institutions from being as forthcoming in the future.

Ten years ago, the bones currently in your body did not actually exist. Like skin, bone is constantly renewing itself, shedding old tissue and growing it anew from stem cells in the bone marrow. Now, a new technique developed at Caltech can render intact bones transparent, allowing researchers to observe these stem cells within their environment. The method is a breakthrough for testing new drugs to combat diseases like osteoporosis.

The research was done in the laboratory of Viviana Gradinaru (BS '05), assistant professor of biology and biological engineering and a Heritage Medical Research Institute Investigator. It appears in a paper in the April 26 issue of Science Translational Medicine.

In healthy bone, a delicate balance exists between the cells that build bone mass and the cells that break down old bone in a continual remodeling cycle. This process is partially controlled by stem cells in bone marrow, called osteoprogenitors, that develop into osteoblasts or osteocytes, which regulate and maintain the skeleton. To better understand diseases like osteoporosis, which occurs when loss of bone mass leads to a high risk of fractures, it is crucial to study the behavior of stem cells in bone marrow. However, this population is rare and not distributed uniformly throughout the bone.

"Because of the sparsity of the stem cell population in the bone, it is challenging to extrapolate their numbers and positions from just a few slices of bone," says Alon Greenbaum, postdoctoral scholar in biology and biological engineering and co-first author on the paper. "Additionally, slicing into bone causes deterioration and loses the complex and three-dimensional environment of the stem cell inside the bone. So there is a need to see inside intact tissue."

To do this, the team built upon a technique called CLARITY, originally developed for clearing brain tissue during Gradinaru's postgraduate work at Stanford University. CLARITY renders soft tissues, such as brain, transparent by removing opaque molecules called lipids from cells while also providing structural support by an infusion of a clear hydrogel mesh. Gradinaru's group at Caltech later expanded the method to make all of the soft tissue in a mouse's body transparent. The team next set out to develop a way to clear hard tissues, like the bone that makes up our skeleton.

In the work described in the new paper, the team began with bones taken from postmortem transgenic mice. These mice were genetically engineered to have their stem cells fluoresce red so that they could be easily imaged. The team examined the femur and tibia, as well as the bones of the vertebral column; each of the samples was about a few centimeters long. First, the researchers removed calcium from the bones: calcium contributes to opacity, and bone tissue has a much higher amount of calcium than soft tissues. Next, because lipids also provide tissues with structure, the team infused the bone with a hydrogel that locked cellular components like proteins and nucleic acids into place and preserved the architecture of the samples. Finally, a gentle detergent was flowed throughout the bone to wash away the lipids, leaving the bone transparent to the eye. For imaging the cleared bones, the team built a custom light- sheet microscope for fast and high-resolution visualization that would not damage the fluorescent signal. The cleared bones revealed a constellation of red fluorescing stem cells inside.

The group collaborated with researchers at the biotechnology company Amgen to use the method, named Bone CLARITY, to test a new drug developed for treating osteoporosis, which affects millions of Americans per year.

"Our collaborators at Amgen sent us a new therapeutic that increases bone mass," says Ken Chan, graduate student and co-first author of the paper. "However, the effect of these therapeutics on the stem cell population was unclear. We reasoned that they might be increasing the proliferation of stem cells." To test this, the researchers gave one group of mice the treatment and, using Bone CLARITY, compared their vertebral columns with bones from a control group of animals that did not get the drug. "We saw that indeed there was an increase in stem cells with this drug," he says. "Monitoring stem cell responses to these kinds of drugs is crucial because early increases in proliferation are expected while new bone is being built, but long-term proliferation can lead to cancer."

The technique has promising applications for understanding how bones interact with the rest of the body.

"Biologists are beginning to discover that bones are not just structural supports," says Gradinaru, who also serves as the director of the Center for Molecular and Cellular Neuroscience at the Tianqiao and Chrissy Chen Institute for Neuroscience at Caltech. "For example, hormones from bone send the brain signals to regulate appetite, and studying the interface between the skull and the brain is a vital part of neuroscience. It is our hope that Bone CLARITY will help break new ground in understanding the inner workings of these important organs."

In my opinion, one of the hardest things to accept is a new type of medical treatment, particularly when it changes the philosophy, parameters and overall results that we are expecting and basically used to receiving. Stem cells are undoubtedly no exception to this rule.

About six weeks ago, Eduardo K (a Cuban doctor with a Masters Degree from the University of Pittsburg in internal medicine and nephrology), brought his wife Maria to our institute, in order to assess the possibility of using stem cells to cure the severe chronic pain in her ankle; a pain so severe that it was basically hindering her ability to walk. Dr. K also expressed his extreme hesitation and concerns about having his wife involved in an invasive ankle surgery at this stage of her adult life.

However, while conducting our usual examining process, reviewing her medical records and MRIs and thoroughly discussing my overall recommendations about a potential stem cell transplant, I quickly realized that Dr. K was not a true believer in Stem Cell therapies, since he thought that there was not much medical evidence of their actual effectiveness and he ultimately also confessed that his wife had basically dragged him to accompany her to this particular appointment.

As always, I respectfully explained the reality that stem cells actually repair the damaged cartilage in a microscopic type fashion and thus, while this repair process would not be clearly reflected immediately on future X-rays, I assured them that the pain she was suffering from will soon subside and possibly even completely disappear. In addition, I expressed that I was extremely confident that she would also regain her mobility skills after the procedure, even if this improvement could not be easily detected via a radiological image.

Since Marias options were somewhat limited, added to the fact that months of traditional physical therapy, injections, medications and previous surgeries had completely failed her, Dr. K finally agreed to grant his wifes wishes to have her stem cell transplant (from her own bone marrow and fat) performed, although he was still very skeptical about the process and was showing little enthusiasm.

This morning, both of them attended our follow up appointment (six weeks after the procedure) and surprisingly, Maria and Dr. K happily confirmed that she felt at least 60 percent better, something that no previous traditional medical treatments had been able to accomplish. It was then that I explained to them that her stem cells had acted much faster than expected (something that possibly taught Dr. K an interesting lesson).

As we began to say our goodbyes, the doctor told me (first in English, then in Spanish) that: in spite of my skepticism about stem cell therapies, I can personally attest that the successful results seen on my wife have been irrefutable, and with a smile on both of their faces, they gratefully thanked my staff and I for this amazing improvement.

As I continued to replay the words expressed by this doctor over and over in my mind, I quickly realized how truly incredulous human beings tend to be, with most of us often needing to fail several times at accomplishing something before being able to realize and accept that we were truly mistaken in the first place!

ow you see it, now you dont: Scientists have used a chemical technique to make mouse bones turn transparent. The technique has been used in the past to make brains and kidneyssee-through, but this marks the first time its been used in hard tissues.

The ability to see within a bone couldhave implications for research into bone diseases, by letting researchers get a more accurate picture of bones internal structure.

The technique is called CLARITY, and since 2013, when it was first described, it has been deployed on a wide variety of mammalian tissues and inplants. Caltech neuroscientistViviana Gradinaru, an original developer of the technique, even cleared an entire mouses body in 2014 (except for its bones, which were unaffected, she said).

advertisement

The approach works by chemically locking proteins and DNA in place with a hydrogel, after which researchers wash away fats within the tissue. Lipids refract light, so this washing step makes CLARITY-treated tissues transparent.

Flexible 3-D printed scaffolds could mend broken bones

In this case, Gradinaruwanted to look at bone marrow and count the number of stem cells that could ultimately produce new bone cells.

Bone is not a static organ. It iscontinuously changed. The bones we have in our body, we didnt have them 10 years ago, she explained. Acontinuous process of bone cell death and bone cell growth ishappening, spurred by progenitor cells in a bones soft, spongy marrow.

But looking for these cells can bechallenging. There arent that many progenitor cells, soextrapolating the number and distribution based ona small sample isnt ideal. Researchers can slice the bone, but cuttingcan damage the edges. Putting images of the sliced bones back together into a coherent, 3-D picture is very difficult, too.A clear bone avoidsslicing altogether.

Doug Richardson, director of imaging at the Harvard Center for Biological Imaging, said the paper represented a step forward in bone clearing. (Richardson was not involved in this research.)

This technique has the potential to monitor bone health or disease progression over larger volumes with greater accuracy, he said.

Gradinarus team has already demonstrated one possible application. They found that a drug for osteoporosis, currently being developed by Amgen, triggered an increase in the number of stem cells in CLARITY-treated bone.Some Amgen scientists were coauthors of the paper.

Using CLARITY let the team more effectively measure the rate of this increase.This is very important, because you want a controlled increase too much of an increase can lead to tumors, Gradinarusaid.

Other uses could be on the horizon. Being able to make a mouse or rat skull see-through could be useful for Gradinarus fellow neuroscientists who use implants in their research and want to establish the exact position of the impact after experiments are done.

Theres still more work to be done. For instance, finding a way to tagthe samples with antibodies without having to cut a bone in half, as researchers did in this paper would be ideal.Gradinaru also wouldnt mind some speed improvements:In this case, the CLARITY process took nearly a month.

Its not a fast method, by any means, Gradinaru said. However, the result theres no substitute for getting 3-D access to the intact bone marrow.

Caroline, 11, Elizabeth, 3, Jon Thomas, 13 and James Christopher Allums, 20, do everything as a family. James Christopher and Elizabeth both have a rare medical condition. Their mother, Ellen Allums, said they all go through the process together and support each other with faith and love.(Photo: Courtesy)

Learning that your child has a rare, life-threatening illness is difficult for any family. Everything changes. One family learned that two of their children share the same rare blood disorder.

"That news that we heard was the worst news that we could hear, but it was the best thing that's ever happened to us. It really changed our perspective. It changed our priorities," Chris Allums said.

"We're no longer the same people we were," Ellen Allums said.

Ellen and Chrishave four childrenJames Christopher, 20,Jon Thomas, 13,Caroline,11, andElizabeth, 3.

James Christopher and Elizabeth have Fanconi anemia, a disease that affects the bone marrow's ability to produce blood. Bone marrow or blood stem cell transplants are considered the best treatments, andthey have not yet found a match for either child.

James Christopher was diagnosed 12 years ago and told he had about 18 monthsto live. The family was told he must received a bone marrow transplant.

"We immediately decided that, first of all, we're going to pray and expect a miracle and grow our faith, and next, we're going to try and see if we can find him a bone marrow match and help others along the way, see how many lives that we can affect, that we can save both spiritually and physically," Ellen said.

More than 16,000 people have been added to the worldwide bone marrow registry as a result of drives held on behalf of the Allums. Ellen said they know of at least 41 lives that have been saved because of those efforts, and they're asking more people to commit to donate.

'Looking for a double miracle'

Ellen said a doctor said someone with FA can be like a duck gliding on the water the surface appearance is calm, but people can't see all the effort that goes into staying in motion.

It has a variety of symptoms such as fatigueand can lead to bone marrow or organ failure. Ellen and Chris said FA patients are 500 times more likely to develop some cancers, such as leukemia. James Christopher is subject to constant screenings.

The disease is genetic. According to the National Organization for Rare Disorders, the incidence rate is 1 in 136,000 births. Ellen said her children are two ofsix in Louisiana affected by FA.

Elizabeth's blood counts have been OK, but doctors have said James Christopher has an immediate need for a transplant. DNA needs to be close to an exact match, and many families find a relative who can donate.Elizabeth is a 100 percent match, but she's ineligible because of her FA.

One donor, once found, could help both.A bone marrow transplant won't cure someone with FA, but it can help prolong life.

"Just because you're having to wait doesn't mean the miracle's not going to come. We've been waiting 12 years, but we still have faith that that miracle's coming. Just because it hasn't happened doesn't mean it's not going to. The timing needs to be right," Ellen said. "In our lives, we're looking for an even greater miracle because we're looking for a double miracle, with two children."

FA patients can require blood and platelet transfusions, after which they may become dependent and need additional rounds, which would require a bone marrow transplant quickly.

James Christopher received his first blood transfusion three weeks ago.

"Chris gave. His daddy gave blood to him, and we felt like it was his heavenly father and his earthly father that gave him that blood, and now we're praying and believing that he never has to receive it again," Ellen said.

She said they've dealt with some scary bleeding issues "like Niagara Falls," and James Christopher has almost lost his life a few times. His parents call him a survivor, a warrior. He gets up and stays active daily, even with low blood counts that doctors thinkwould cause fatigue.

"I love to prove doctors wrong. If they give me a boundary, I want to cross it, definitely, when it comes to that," he said. He likes to tell people "keep calm and carry on," like the World War II posters.

Every bump, scratch, scrape and bruise for the siblings is noteworthy, and the whole family works to avoid germs. A simple cough or cold could be devastating, so they're all in tune to notice illness.They're very aware of the importance of handwashing and staying home if ill. Chris said during cold and flu season, they often come in, shower and change clothes before interacting with the others.

Ellen said they respect people who choose not to vaccinate, but all of her children have been vaccinated because measles or chicken pox can kill someone with FA.

All the children home school to help prevent illness. When James Christopher was diagnosed, doctors said it could help him live longer. Chris said all four have excelled fromthe one-on-one time, and they've enjoyed getting to know other families inthe Christian Homeschool Association.

The Allums know their lives are different than those of many other families, but they are running their own race.

"I have to tell you that we have a wonderful life. Sure it's full of hard work, but it's wonderful because of what the Lord has done with it," Chris said.

Joy in the journey

The couple did their homework on hospitals that specialize in the disease and settled on Memorial Sloan Kettering Hospital's cancer center in New York. It had the best survival rates, and they've been going for 12 years.

James Christopher's and Elizabeth's immunity is low, the family cannot travel with the general public. They either have to make the almost 20-hour drive or arrange for a private plane. Ellen said they've had to go there, at times, every three to six months.

The whole family travels to medical appointments.

"Although they don't have the disease, they go through it with them," Ellen said of Jon Thomas and Caroline. She said all of her children have gone to hospitals and played with and prayed for children were facing terminal diagnoses. It's been a blessing to them and a ministry to others.

James Christopher said they try to find fun in the journey. Ellen said they do something fun every time they go to the hospital and embrace John 10:10Jesus came that we might have life and have it abundantly.

What happens if there's a match?

"We would be moving to New York for six to eight months for the bone marrow transplant," Ellen said.

Ellen said the a bone marrow recipient with FA will have to go through chemotheraphy for two weeks to kill off the patient's natural bone marrow.

"When the cells are dead, then they receive someone else's bone marrow. It's a liquid, it looks just like an IV, and they lie there and you just pray to God that it's going to take," she said.

After the transplant, the patient is in isolation for 30-40 days. They stay at the transplant hospital for six to eight months and keep a medical mask on for one year. Chris said you hope graph vs. host disease isn't an issue.

Saving lives

She said she used to look at missions that dig wells in other countries and wish they could go save lives, but, after prayer, she realized they are saving people. With the help of family and friends, efforts to add bone marrow donors have helped dozens of people.

"I like to tell people 'You could be the reason someone lives.' ... And I think those words are pretty powerful" Ellen said.

She said the process to donate blood stem cells, which is the most common donation method, involves a needle in each arm for four to six hours.

"It's not even a surgery. It's not like giving a kidney or a lung or a heart, even, but the benefits are that strong. It can truly save a life, but yet all you have to do is like giving blood," Ellen said.

To test for a match, she said, it's even less of a commitment. It takes about five minutes to fill out paperwork and provide a swap from inside the cheek. Anyone 18-55 in good health can register.

The community has come together to help organize a drive for May 1, National Fanconi Anemia Day. A massive drive will take place at more than a dozen locations across northeastern Louisiana, and CenturyLink will be registering employees on-site.Anyone anywhere can order testing kitsonline atdkms.orgorbethematch.org.

A month after testing, people will get a phone call to confirm their position on the registry. Ellen said they pray people will make the commitment.Previous drives for the Allumshave set national records for most registered in one day. Over three days, they tested 5,000 people.

"When people come, we want to educate them on the processin hopes thatwhetherthey are a match in a month or a match in 20 yearsthat they will be committed to beingon that registry to help somebody," Chris said.

They heard of a woman who registered with her family at a previous event andlater developed leukemia. Her sister was found as an instant bone marrow match because theyalreadyhad been tested.

Ellen and Chris said knowing that 41 lives were saved as a result of their family'sefforts makes it all worth it, even though it hasn't been easy.

"But we believe that God is going to heal them both because He told us He would, and we believe that. We hold on to those promises of God. ... and we focus on that. That gives us strength," Ellen said.

Family seeks 'miracle' for siblings, saves lives in the process - Monroe News Star

Using human skin cells, University of California, Irvine neurobiologists and their colleagues have created a method to generate one of the principle cell types of the brain called microglia, which play a key role in preserving the function of neural networks and responding to injury and disease.

The finding marks an important step in the use of induced pluripotent stem (iPS) cells for targeted approaches to better understand and potentially treat neurological diseases such as Alzheimer's. These iPS cells are derived from existing adult skin cells and show increasing utility as a promising approach for studying human disease and developing new therapies.

Skin cells were donated from patients at the UCI Alzheimer's Disease Research Center. The study, led by Edsel Abud, Wayne Poon and Mathew Blurton Jones of UCI, used a genetic process to reprogram these cells into a pluripotent state capable of developing into any type of cell or tissue of the body.

The researchers then guided these pluripotent cells to a new state by exposing the cells to a series of differentiation factors which mimicked the developmental origin of microglia. The resulting cells act very much like human microglial cells. Their study appears in the current issue of Neuron.

In the brain, microglia mediate inflammation and the removal of dead cells and debris. These cells make up 10- to 15-percent of brain cells and are needed for the development and maintenance of neural networks.

"Microglia play an important role in Alzheimer's and other diseases of the central nervous system. Recent research has revealed that newly discovered Alzheimer's-risk genes influence microglia behavior. Using these cells, we can understand the biology of these genes and test potential new therapies," said Blurton-Jones, an assistant professor of the Department of Neurobiology & Behavior and Director of the ADRC iPS Core.

"Scientists have had to rely on mouse microglia to study the immunology of AD. This discovery provides a powerful new approach to better model human disease and develop new therapies," added Poon, a UCI MIND associate researcher.

Along those lines, the researchers examined the genetic and physical interactions between Alzheimer's disease pathology and iPS-microglia. They are now using these cells in three-dimensional brain models to understand how microglia interact with other brain cells and influence AD and the development of other neurological diseases.

"Our findings provide a renewable and high-throughput method for understanding the role of inflammation in Alzheimer's disease using human cells," said Abud, an M.D./Ph.D. student. "These translational studies will better inform disease-modulating therapeutic strategies."

The DMC reviewed all of the accumulated safety data to date. The review included the safety data from six complete cervical injury (AIS-A) patients dosed with 10 million AST-OPC1 cells in Cohort 2, each of whom have completed at least six months of follow-up, as well as initial safety data from the currently enrolling Cohorts 3 and 4. Cohort 3 is enrolling AIS-A patients dosed with the highest dose of 20 million cells; Cohort 4 is testing 10 million cells in patients with less severe AIS-B incomplete cervical spinal cord injuries. In addition, the DMC reviewed the ongoing long-term safety data from the study's initial cohort of three patients dosed with 2 million cells, all of whom completed 12 months of follow-up in 2016.

As specified in the SCiStar study protocol, the DMC meets on a regular basis to review data from the ongoing trial. The DMC is comprised of an independent group of medical and scientific experts and is responsible for reviewing and evaluating patient safety and efficacy data for safeguarding the interest of study participants.

Asterias previously reported on positive early efficacy data from Cohort 2 (AIS-A; 10 million cells) of the SCiStar study. Patients from this cohort showed improvement in upper extremity motor function at 3-months following administration of AST-OPC1 and maintained or further increased this improvement at 6-months and 9-months. The results suggest a meaningful and favorable difference to date in recovery of arm, hand and finger function in patients treated with the 10 million cell dose of AST-OPC1 as compared to the level of expected rates of spontaneous recovery shown from historical control data of a closely matched patient population. Asterias expects to report additional efficacy and safety data for Cohort 2, as well as for the currently-enrolling Cohorts 3 and 4, later this year.

About the SCiStar Trial

The SCiStar trial is an open-label, single-arm trial testing three sequential escalating doses of AST-OPC1 administered at up to 20 million AST-OPC1 cells in as many as 35 patients with sub-acute, C-5 to C-7, motor complete (AIS-A or AIS-B) cervical SCI. These individuals have essentially lost all movement below their injury site and experience severe paralysis of the upper and lower limbs. AIS-A patients have lost all motor and sensory function below their injury site, while AIS-B patients have lost all motor function but may retain some minimal sensory function below their injury site. AST-OPC1 is being administered 14 to 30 days post-injury. Patients will be followed by neurological exams and imaging procedures to assess the safety and activity of the product.

The study is being conducted at six centers in the U.S. and the company plans to increase this to up to 12 sites to accommodate the expanded patient enrollment. Clinical sites involved in the study include the Medical College of Wisconsin in Milwaukee, Shepherd Medical Center in Atlanta, University of Southern California (USC) jointly with Rancho Los Amigos National Rehabilitation Center in Los Angeles, Indiana University, Rush University Medical Center in Chicago and Santa Clara Valley Medical Center in San Jose jointly with Stanford University.

Asterias has received a Strategic Partnerships Award grant from the California Institute for Regenerative Medicine, which provides $14.3 million of non-dilutive funding for the Phase 1/2a clinical trial and other product development activities for AST-OPC1.

Additional information on the Phase 1/2a trial, including trial sites, can be found at http://www.clinicaltrials.gov, using Identifier NCT02302157, and at the SCiStar Study Website (www.SCiStar-study.com).

About AST-OPC1

AST-OPC1, an oligodendrocyte progenitor population derived from human embryonic stem cells, has been shown in animals and in vitro to have three potentially reparative functions that address the complex pathologies observed at the injury site of a spinal cord injury. These activities of AST-OPC1 include production of neurotrophic factors, stimulation of vascularization, and induction of remyelination of denuded axons, all of which are critical for survival, regrowth and conduction of nerve impulses through axons at the injury site. In preclinical animal testing, AST-OPC1 administration led to remyelination of axons, improved hindlimb and forelimb locomotor function, dramatic reductions in injury-related cavitation and significant preservation of myelinated axons traversing the injury site.

In a previous Phase 1 clinical trial, five patients with neurologically complete, thoracic spinal cord injury were administered two million AST-OPC1 cells at the spinal cord injury site 7-14 days post-injury. They also received low levels of immunosuppression for the next 60 days. Delivery of AST-OPC1 was successful in all five subjects with no serious adverse events associated with AST-OPC1. No evidence of rejection of AST-OPC1 was observed in detailed immune response monitoring of all patients. In four of the five patients, serial MRI scans indicated that reduced spinal cord cavitation may have occurred. Based on the results of this study, Asterias received clearance from FDA to progress testing of AST-OPC1 to patients with complete cervical spine injuries, which represents the first targeted population for registration trials.

Piero Anversa

Brigham and Womens Hospital and its parent healthcare network have agreed to pay $10 million to the U.S. government to resolve allegations it fraudulently obtained federal funding.

The case, which involves three former Harvard stem cell researchers, dates back several years. In 2014, Circulation retracted a paper by Piero Anversa, Annarosa Leri, and Jan Kajstura, among others, amidst a university investigation into misconduct allegations. Anversa and Leri whose lab was described as filled with fear by one former research fellow later sued the hospital for notifying journals of that investigation. They lost.

In the agreement announced today by the Department of Justice (DOJ), Partners Healthcare and Brigham and Womens Hospital have agreed to pay the government $10 million to settle allegations that the researchers fraudulently obtained funding from the National Institutes of Health:

The settlement resolves allegations that Dr. Anversa, along with Dr. Annarosa Leri and Dr. Jan Kajstura, knew or should have known that their laboratory promulgated and relied upon manipulated and falsified information, including confocal microscope images and carbon-14 age data for cells, in applications submitted for NIH research grant awards concerning the purported ability of stem cells to repair damage to the heart. The government alleges that problems with the work of the laboratory included improper protocols, invalid and inaccurately characterized cardiac stem cells, reckless or deliberately misleading record-keeping, and discrepancies and/or fabrication of data and images included in applications and publications. The government contends that, at the direction of these BWH scientists, the Anversa laboratory included false scientific information in claims to NIH in order to obtain and use funds from NIH grants.

John Thomas, a partner with Gentry Locke who represents whistleblowers who raise allegations of misconduct, told us that other cases have settled for large amounts such as a recent settlement with Columbia University for $9.5 million. But there are other elements that make this latest announcement noteworthy, he said.

Specifically, most settlements involve some black and white failure in research administration, such as misrepresenting a researchers qualifications on a grant, misreporting effort, or conducting the research at a different facility (such as the Columbia case), said Thomas. The latest decision, in contrast, goes to the science itself.

As a result, he said:

This demonstrates the government is still willing to step in even when its not an administrative issue, even when it goes to the merits of the actual misconduct allegations. I think it shows that when the government awards grants, one of the things its intending to get is good and honest science. The science matters.

We reached out to Anversa and Levi; in response, we received a statement from their attorney:

It is outrageous that BWH has sought to unfairly tarnish the reputations of Drs Anversa and Leri, scientists who have pioneered groundbreaking work in cardiac stem cell reproduction and who have litigation pending against BWH and its president, Betsy Nabel.

Neither Dr. Anversa nor Dr. Leri was involved in the settlement process. BWH self-reported allegations in its own way for its own purposes. It has long been known that Drs. Anversa and Leri relied on the work of a senior scientist in the lab in presenting data for grants and in publications. No one has ever shown that either Dr. Anversa or Dr. Leri participated in the fraud or was aware of it at the time.

BWHs allegations and settlement cannot take away from Drs. Anversa and Leris contributions to the science of stem cell replication. There are Phase II trials being conducted by NIH currently on stem cell treatments based on their work. Taxpayer money was rightly used to further the fight against heart disease, a leading cause of death in this country.

According to the U.S. Attorneys Office, Brigham and Womens Hospital brought the allegations to the governments attention:

After learning of the allegations of research misconduct in the Anversa laboratory, BWH investigated the allegations, disclosed its concerns to the U.S. Department of Health and Human Services, Office of the Inspector General (OIG) and Office of Research Integrity, and then worked cooperatively with OIG and the Department of Justice to explain the bases for the allegations.

The three researchers Anversa, Leri, and Kajstura are no longer based at Brigham and Womens Hospital. Earlier this year, Anversa and Leri published a paper about cardiac progenitor cells that lists an affiliation at the Swiss Institute for Regenerative Medicine.

In todays statement, Acting U.S. Attorney William D. Weinreb said:

Individuals and institutions that receive research funding from NIH have an obligation to conduct their research honestly and not to alter results to conform with unproven hypotheses.
