Spinal Cord Injury Treatment Status and Improvements after Treatment

Till the end of 2014, our department has treated 3166 patients with sequela of spinal cord injury, including 1452 patients with cervical cord injury, 1193 patients with thoracic cord injury (do not include T12-L1), 216 patients with both cervical cord and thoracic cord injury, and 305 patients with thoracic and lumbar cord injury (mainly T12-L1). We invented CT-guided intraspinal injection in 2006 and stem cell transplantation via endovascular intervention in 2011 to treat sequela of spinal cord injury, which apparently improved the treatment effect. Since 2011, the improvement rate of patients with sequela of spinal cord injury has reached 96%......Read More >>

BUFFALO, N.Y. A discovery, several years in the making, by a University at Buffalo research team has proven that adult skin cells can be converted into neural crest cells (a type of stem cell) without any genetic modification, and that these stem cells can yield other cells that are present in the spinal cord and the brain.

The applications could be very significant, from studying genetic diseases in a dish to generating possible regenerative cures from the patients own cells.

Its actually quite remarkable that it happens, says Stelios T. Andreadis, PhD, professor and chair of UBs Department of Chemical and Biological Engineering, who recently published a paper on the results in the journal Stem Cells.

The identity of the cells was further confirmed by lineage tracing experiments, where the reprogrammed cells were implanted in chicken embryos and acted just as neural crest cells do.

Stem cells have been derived from adult cells before, but not without adding genes to alter the cells. The new process yields neural crest cells without addition of foreign genetic material. The reprogrammed neural crest cells can become smooth muscle cells, melanocytes, Schwann cells or neurons.

In medical applications this has tremendous potential because you can always get a skin biopsy, Andreadis says. We can grow the cells to large numbers and reprogram them, without genetic modification. So, autologous cells derived from the patient can be used to treat devastating neurogenic diseases that are currently hampered by the lack of easily accessible cell sources.

The process can also be used to model disease. Skin cells from a person with a genetic disease of the nervous system can be reprogrammed into neural crest cells. These cells will have the disease-causing mutation in their chromosomes, but the genes that cause the mutation are not expressed in the skin. The genes are likely to be expressed when cells differentiate into neural crest lineages, such as neurons or Schwann cells, thereby enabling researchers to study the disease in a dish. This is similar to induced pluripotent stem cells, but without genetic modification or reprograming to the pluripotent state.

The discovery was a gradual process, Andreadis says, as successive experiments kept leading to something new. It was one step at a time. It was a very challenging task that took almost five years and involved a wide range of expertise and collaborators to bring it to fruition, Andreadis says. Collaborators include Gabriella Popescu, PhD, professor in the Department of Biochemistry in the Jacobs School of Medicine and Biomedical Sciences at UB; Song Liu, PhD, vice chair of biostatistics and bioinformatics at Roswell Park Cancer Institute and a research associate professor in biostatistics UBs School of Public Health and Health Professions; and Marianne Bronner, PhD, professor of biology and biological engineering, California Institute of Technology.

Andreadis credits the persistence of his then-PhD student, Vivek K. Bajpai, for sticking with it.

He is an excellent and persistent student, Andreadis says. Most students would have given up. Andreadis also credits a seed grant from UBs office of the Vice President for Research and Economic Developments IMPACT program that enabled part of the work.

The work recently received a $1.7 million National Institutes of Health grant to delve into the mechanisms that occur as the cells reprogram, and to employ the cells for treating the Parkinsons-like symptoms in a mouse model of hypomyelinating disease.

This work has the potential to provide a novel source of abundant, easily accessible and autologous cells for treatment of devastating neurodegenerative diseases. We are excited about this discovery and its potential impact and are grateful to NIH for the opportunity to pursue it further, Andreadis said.

The research, described in the journal Stem Cells under the title Reprogramming Postnatal Human Epidermal Keratinocytes Toward Functional Neural Crest Fates, was supported by grants from the National Institutes of Health.

From skin to brain: Stem cells without genetic modification - UB News Center

Spinal Cord Stem Cells Comments Off on From skin to brain: Stem cells without genetic modification – UB News Center | March 22nd, 2017

Spinal cord injuries are among the most dramatic and devastating of all injuries, in part because they stem from traumatic accidents but also because there are very few treatment options.

While medical advances have been made in the areas of injury management and improved long-term functioning, for those dealing with spinal cord injuries the sad truth is that researchers have yet to come up with a cure for paralysis.

Victims of spinal cord injuries are left facing a lifelong disability, one that comes not only with a range of personal burdens but which also extracts its toll on the healthcare system studies have shown that the lifetime economic burden of spinal cord injuries in Canada ranges between $1.5 to $3.0 million per individual.

Yet cell therapies represent one area of current research that appears likely to deliver positive results. According to a new study from researchers with the University Health Network and the University of Toronto, the neuroregenerative potential of this approach is promising.

Cell therapy, which in general refers to any procedure involving the implantation of cells, comes in different guises in spinal cord research, depending on the type of cells employed. Clinical research is already being performed using stem cells, which have the ability to self-renew and to differentiate into a variety of specialized cells, and glial cells, which support neural functioning.

The aim in both cases is to introduce the new cells so as to encourage regrowth of nerve fibres where they have been severed and thereby restore nerve function, a seemingly impossible task, since along with the structural damage caused by spinal cord injury comes a series of secondary events such as scarring and inflammation which, although normal bodily repair processes, can effectively impede the chances at regrowth and reconnection of neural networks.

_________________________________________________________________________________________________________________________________________

_____________________________________________________________________________________________________________________________________________

Reviewing the current state of affairs in spinal cord research, the researchers find that cell therapies, especially those that combine more than one approach, are showing promise but need further study and clinical trials. While combinatorial treatments using cell-coupling, trophic factors, biomaterials, and rehabilitation, may help to improve stem cell effectiveness among a heterogeneous patient population, there is still much research required to optimize their application, say the studys authors.

The researchers found that in early clinical trials, for example, cell therapies have shown modest improvements connected to functional recovery, yet they say that the results are encouraging and that even slight enhancements in sensation and function for those dealing with spinal cord injuries are often quite meaningful. It is clear that a lot remains to be understood in the translation of stem cell therapies, say the studys authors. However, given the significant strides in laboratory work, we should not lose sight of their potential.

The new research is published in the journal Expert Opinion on Biological Therapy.

The primary causes of spinal cord injuries are motor vehicle accidents and unintentional falls, each accounting for a little over 40 per cent of spinal cord injuries. According to Spinal Cord Injury Ontario, there are 1,500 new spinal cord injuries each year and a total of 86,000 Canadians currently living with spinal cord injuries.

Electroacupuncture triggers a neurological response that releases stem cells that can relieve injury-induced pain, and help promote tissue repair, says a study in the journal Stem Cells led by Indiana University School of Medicine.

The school outlined its findings in a media release:

Electroacupuncture is a form of acupuncture that uses a small electrical current to augment the ancient Chinese medical practice of inserting fine needles into the skin at pre-determined points throughout the body.

For the study, a team of more than 40 scientists at institutions in the United States and South Korea was led by four senior authors including IU School of Medicines Maria B. Grant, MD, Marilyn Glick Professor of Ophthalmology and co-corresponding author; Mervin C. Yoder, MD, IU Distinguished Professor, Richard and Pauline Klingler Professor of Pediatrics, associate dean for entrepreneurial research at IU School of Medicine, director of the Herman B Wells Center for Pediatric Research and co-corresponding author; and Fletcher A. White, PhD, Vergil K. Stoelting Chair ofAnesthesia, professor of anesthesia, pharmacology and toxicology.

This work is a classic example of the power of team science, where investigators in different institutions with specific expertise worked together to unravel the complexity of how electroacupuncture works to help the body respond to stressors, said Dr. Yoder.

The researchers performed a series of lab tests involving humans, horses and rodents that follow the effects of electroacupuncture from the stimulus of the needle all the way to the brain, resulting in the release of reparative mesenchymal stem cells (MSCs) into the bloodstream.

Depending on the species, electroacupuncture led to activation of the hypothalamusa part of the brain that controls the nervous system and involuntary bodily functions such as heart rate and digestionwithin nine to 22 minutes. The stem cells were mobilized within two hours.

The acupuncture stimulus were giving these animals has a rapid effect on neuroanatomical pathways that connect the stimulus point in the arm to responsive neurons in the spinal cord and into a region in the brain called the hypothalamus. In turn, the hypothalamus directs outgoing signals to stem cell niches resulting in their release, said Dr. White, who is a neuroscientist at the Richard L. Roudebush VA Medical Center in Indianapolis.

The researchers found electroacupuncture treatments resulted in higher thresholds for injury-induced pain, as well as considerable increases in the presence of a type of collagen that promotes tendon repair and anti-inflammatory cells known to be predictors of faster healing time.

Dr. White said these findings could lead to new strategies for tissue repair and pain management related to injuries.

We could potentially capture the MSCs from an individuals blood following electroacupuncture and save the cells for future re-introduction in the patient post-surgery or to treat chronic pain due to an injury, he said.

The horses used in the study had been injured during training for international dressage competitions, and the six people who took part were healthy volunteers, who still showed activation of their hypothalamus through brain imaging.

Three women suffering from a degenerative eye condition were blindedlikely permanentlyin a clinical trial for stem cell therapy, according to a report published Wednesday in the New England Journal of Medicine.

The women, who were all between the ages of 72 and 88, had a common medical condition called age-related macular degeneration, in which cells in the retina begin to die off, resulting in spotty or blurred vision. Researchers suspected stem cells derived from the patient's own body could regenerate some of the cells lost to the disease. So in the clinical trial, which was conducted in 2015, researchers removed some blood and fat from participants' anesthetized abdomens, treated the cells in a standardized way to make them revert to stem cells, then injected into their eyes. They were instructed to use an eyedrops antibiotic for a few days. The three patients had found the trial listed on the government web site clinicaltrials.gov, and had each paid $5,000 for the procedure. The informed consent form listed that blindness was possible as a result of the procedure.

MoreIt's Shockingly Easy To Buy Unregulated Stem Cell Treatments

A few days after the patients received the injected stem cells, the participants ended up in the hospital with vision loss, detached retinas, and hemorrhage. The patients lost vision; subsequent checkups led doctors to conclude that they would likely never regain their sight.

Despite the fact that the participants found the procedure on clinicaltrials.gov, the informed consent forms do not mention that it is in fact a clinical trial. "The patients paid for a procedure that had never been studied in a clinical trial, lacked sufficient safety data, and was performed in both eyes on the same day," the study authors write. Injecting something experimental into both eyes is both not safe and not typical, they continue.

Recently researchers have been testing lots of different medical uses for stem cells, from treating multiple sclerosis to spinal cord injuries. With the passage of the 21st Century Cures Act in December, Congress cleared the way for faster regulatory approval for promising treatments based on stem cells. At least 13 clinical trials were registered to treat AMD alone as of November 2016, the article authors write.

But anecdotes like these bolster those who counsel restraint when it comes to stem cells. "Although numerous stem-cell therapies for medical disorders are being investigated at research institutions with appropriate regulatory oversight, many stem-cell clinics are treating patients with little oversight and with no proof of efficacy," the article authors write.

Jeffrey Goldberg, a professor of ophthalmology at Stanford University and one of the authors of the article, calls this a "call to awareness for patients, physicians and regulatory agencies of the risks of this kind of minimally regulated, patient-funded research," according to a press release.

Xue-Jun Li spends her days studying motor neurons, the cells that send signals from the brain to the body's voluntary muscles.

Motor neuron diseases are degenerative, which means that the muscles don't stop working all at once. When the motor neurons begin to fail, one slowly loses control of the arms and legs, the ability to swallow and, eventually, to breathe.

Scientists know very little about the human nervous system and what causes the motor neurons to stop functioning. Li has published more than 37 peer-reviewed manuscripts and has developed human stem cell models for spastic paraplegias and spinal muscular atrophy, which is the leading genetic cause of death for infants.

Li joined the University of Illinois College of Medicine at Rockford as an associate professor in the Biomedical Sciences Department last May. Her research is supported by the National Institute of Health and ALS Association, among others.

I love the satisfaction of new discoveries, new ideas you get from working in the lab, the interaction with students, she said. But any breakthrough you make is a collaboration.

Her stem cell research is concerned with, among other things, an attempt to better understand microtubule defects that disrupt signals from the brain to motor neurons along the spinal cord. Mitochondrial defects the mitochondria are the energy factories of the cells are another focus.

This fall, Li will teach a class that's a first for the university: stem cells and regenerative engineering.

-NSI-566 Achieved Robust Engraftment and Long-Term Survival After Transplantation-

- Data Published in Journal of Neurotrauma-

GERMANTOWN, Md., March 09, 2017 (GLOBE NEWSWIRE) -- Neuralstem, Inc. (Nasdaq:CUR), a biopharmaceutical company focused on the development of nervous system therapies based on its neural stem cell technology, announced the recent publication of preclinical data on NSI-566 spinal cord-derived neural stem cells in Journal of Neurotrauma. These data showed robust engraftment and long-term survival of NSI-566 post transplantation in a rat model of penetrating ballistic-like brain injury (PBBI). NSI-566 is Neuralstems lead stem cell therapy candidate.

The study entitled, Amelioration of penetrating ballistic-like brain injury induced cognitive deficits after neuronal differentiation of transplanted human neural stem cells," was led by Ross Bullock, M.D., Ph.D., The Miami Project to Cure Paralysis, University of Miami School of Medicine. These are the first data from the 4-year proof-of-concept research program, funded by the United States Department of Defense, for NSI-566 in traumatic brain injury.

These data on NSI-566 are encouraging, particularly since researchers have long been challenged to achieve durable engraftment and survival of neural stem cells after transplantation, said Dr. Bullock. No long-term treatment beyond physical therapy is currently available to restore cognition after a traumatic brain injury. Transplantation of stem cells into the injured brain may allow a unique replacement therapy and fill a significant medical need.

Researchers transplanted NSI-566 into rats 7-10 days after PBBI. The rats were immunosuppressed to enable survival of NSI-566 neural stem cells. Robust engraftment with evidence of prominent neuronal differentiation was observed after 4 months, and axons from grafted cells extended a significant distance from the graft site along host white matter tracts.

These data continue to support our research and development platform. The results provide additional insight into our proprietary regionally specific stem cells and their potential benefits in nervous system disorders, said Karl Johe, Ph.D., Chief Scientific Officer, Neuralstem. We look forward to additional preclinical data from this collaboration with Dr. Bullocks group to support the potential use of NSI-566 in traumatic brain injury.

About Neuralstem Neuralstems patented technology enables the commercial-scale production of multiple types of central nervous system stem cells, which are being developed as potential therapies for multiple central nervous system diseases and conditions.

Neuralstems technology enables the discovery of small molecule compounds by systematic screening chemical compounds against its proprietary human hippocampal stem cell line. The screening process has led to the discovery and patenting of molecules that Neuralstem believes may stimulate the brains capacity to generate new neurons, potentially reversing pathophysiologies associated with certain central nervous system (CNS) conditions.

The company has completed Phase 1a and 1b trials evaluating NSI-189, a novel neurogenic small molecule product candidate, for the treatment of major depressive disorder or MDD, and is currently conducting a Phase 2 efficacy study for MDD.

Neuralstems stem cell therapy product candidate, NSI-566, is a spinal cord-derived neural stem cell line. Neuralstem is currently evaluating NSI-566 in three indications: stroke, chronic spinal cord injury (cSCI), and Amyotrophic Lateral Sclerosis (ALS).

Neuralstem is conducting a Phase 1 safety study for the treatment of paralysis from chronic motor stroke at the BaYi Brain Hospital in Beijing, China. In addition, NSI-566 was evaluated in a Phase 1 safety study to treat paralysis due to chronic spinal cord injury as well as a Phase 1 and Phase 2a risk escalation, safety trials for ALS. Subjects from all three indications are currently in long-term observational follow-up periods to continue to monitor safety and possible therapeutic benefits.

News: A global licensing agreement between Seattle Genetics (SGEN) and Immunomedics, worth over $2 billion, has been put on hold by a Delaware judge, following an injunction filed by venBio Select Advisor LLC, the largest shareholder of Immunomedics, to block the deal.

The license agreement between Seattle Genetics and Immunomedics was signed last month, and it involves antibody-drug conjugate, Sacituzumab govitecan, or IMMU-132.

Sacituzumab Govitecan (IMMU-132) is Immunomedics' lead investigational drug. As part of the agreement, Seattle Genetics is responsible for initiating phase III clinical trials of IMMU-132 in patients with metastatic triple-negative breast cancer (TNBC) and will be responsible for submitting the initial Biologics License Application to the FDA for accelerated approval.

VenBio is seeking to thwart the deal saying it undervalues the potential of IMMU-132. Now that a temporary restraining order has been placed on the deal, maybe there is an opportunity for a better deal.

Spinal Cord Stem Cells Comments Off on Gainers & Losers Of Mar.9: CBAY, IMMU, TGTX, NSPR, TNDM… – RTT News | March 10th, 2017

Stem cell therapy is a quickly advancing treatment being used across the country. Now, its becoming more prevalent in eastern North Carolina to those living with chronic pain an alternative to surgery. The minimally invasive procedure is showing results in alleviating back, knee, hip and shoulder pain. Though stem cell therapy is classified by the Food and Drug Administration as experimental, patients say theyre finding relief. Meet New Bern resident and a local endodontist Dr. Donnie Luper. He was skeptical of the procedure at first.

How did you know what those stem cells were going to differentiate into? I mean was I going to grow a foot out of my shoulder or something like that?

Luper tore his rotator cuff 25 years ago during a tubing incident on the Trent River. A subsequent fall during a golf trip in 2015 sent him to a specialist.

I went to see a shoulder surgeon in Richmond. He told me that he didnt think it was a complete tear of my rotator cuff, that I could probably have a minor surgical procedure done and I asked him about stem cell.

After talking with a friend who opted for stem cell treatment for her knee pain, Luper decided to find out more.

My option was if I would have had that shoulder surgery and they had do that bicep tendon repair, I mean I would have been in a sling for six weeks and probably not working for three months.

According to the Food and Drug Administration, stem cells sometimes called the bodys master cells - have the ability to divide and develop into many different cell types. Each new cell has the potential to remain a stem cell or become another type of cell, such as a nerve cell, a skin cell, or a red blood cell. They may also help repair the body by dividing to replenish cells that are damaged by disease, injury or normal wear. Parkinsons disease, spinal cord injuries, damaged organs and cancer could all be possibly treated with the use of stem cells, but more research is needed. Dr. Angelo Tellis is the owner/physician of Aegean Medical, which provides stem cell therapy to patients in Cary, Jacksonville, Morehead City and New Bern.

The adult stem cells we call multipotent stem cells so they can only differentiate into very specific or certain kinds of tissue. Whereas the embryonic stem cells we call pluripotent and can become a variety, almost any tissue. But I only deal with adult stem cells, theyre found to be more useful in clinical applications.

Dr. Tellis says adult stem cells are more responsive to growing tissue in very specific locations. When patients go into Dr. Tellis office for the two hour procedure, he starts by numbing an area of the abdomen and performing liposuction to collect one or two syringes of body fat.

Stem cells can be found in a lot of different tissues throughout the body, but theyre actually in one of the highest concentrations in your own body fat.

The stem cell sample is combined with platelet rich plasma or PRP collected through a blood draw.

That has a lot of the chemical signals and messengers that activate stem cells. So Ill typically combine that with some of the stem cells collected from the body fat and then go under x-ray guidance and put it exactly in the targeted location where we want to create that healing process.

Soreness and stiffness can be expected immediately following the procedure and for about a week after. Dr. Tellis says the results tend to improve with time, taking about three to six months for full recovery. This was Lupers experience in 2016.

Really didnt have to take any pain medications. The joint was really sore over the weekend just because of the injection of the fluid there and after that, I had a small amount of discomfort, but nothing I really had to take medication for.

After three months, Luper says he felt 90 percent better. But he decided to get a second opinion from a shoulder surgeon.

And he told me he thought the stem cells had done a lot but that I still had one little bone spur that was rubbing against the muscle and constantly tearing the little bit of the muscle.

After surgery, Luper says his left shoulder started feeling significantly better in about a month. He was also able to return to one of his favorite pastimes golf. While surgery helped eliminate all of his pain, Luper believes stem cells helped regenerate tissue that was damaged years ago.

He said my rotator cuff muscle didnt even look like it had been torn. I actually tore that, Im sixty now, and I actually tore that when I was 34, 35 tubing on the river and I had to do physical therapy for about three months, but he said he saw absolutely no evidence that Id ever had a rotator cuff tear.

Even though some have found relief and possibly a cure through stem cell therapy, the Food and Drug Administration has not approved any stem cell-based products for use, other than HEMACORD (HE-muh-cord). According to their website, the use of stem cells raises safety concerns such as excessive cell growth, the development of tumors as well as cells migrating from the site of administration and differentiating into inappropriate cell types. And then, theres the cost of the procedure, which is not covered by insurance. The price for the treatment ranges from $2,500 to $5,000. But for those who want to avoid major surgery and the downtime associated with recovery, the risk and cost may be worth it.

If Id have surgery, my deductible would have been that because I have an out-of-pocket max. And I would want to do anything to avoid surgery, especially something that would keep me out of work for three months.

The FDA recommends that consumers interested in stem cell therapy should start a conversation with their doctor about the potential risk to benefit ratio. In addition to Aegean Medical, Advanced Health and Physical Medicine in Greenville and Regenerative Medicine Clinic of Wilmington also provide stem cell therapy in eastern North Carolina.

Stem Cell Therapy An Option For ENC Patients | Public Radio East - Public Radio East

Spinal Cord Stem Cells Comments Off on Stem Cell Therapy An Option For ENC Patients | Public Radio East – Public Radio East | March 7th, 2017

A U.S. biotech company is preparing to start experiments using stem cells to try to stimulate 20 brain-dead patients back to life. And no, this isn't an elevator pitch for a sci-fi horror film.

The Mind Unleashed reports the company Bioquark will be trying to use stem cells to regrow and stimulate neurons to bring the patients back from brain death. It works like this: They implant stem cells in the patient's brain while also infusing the spinal cord with chemicals typically used to try and wake up coma patients. Then, hopefully, brain activity is essentially 'jump-started.' The technique is untested, so these experiments will go a long way toward proving (or disproving) the viability of the process.

Bioquark CEO Ira Pastor said they hope to see some results within 2-3 months after treatment begins, with the long-term goal being to develop techniques for brain-dead patients to eventually be able to make a full recovery. Which is certainly a heady, and ethically tricky, goal. You know, and also kind of scary. Ambitious and potentially live-saving, but still a little freaky.

What do you think of the technique? Is this going to revolutionize brain recovery or be the first step toward the T-virus?

Spinal Cord Stem Cells Comments Off on Suicide Switch for Transplanted Stem Cells – The Scientist | March 2nd, 2017

Notes This is a 7-day-old embryo that scientists kept alive in a laboratory dish. If it developed further, the clusters in green would become cells that shape the body and the red/purple cells would form the placenta.

Ali Brivanlou slides open a glass door at the Rockefeller University in New York to show off his latest experiments probing the mysteries of the human embryo.

"As you can see, all my lab is glass just to make sure there is nothing that happens in some dark rooms that gives people some weird ideas," says Brivanlou, perhaps only half joking.

Brivanlou knows that some of his research makes some people uncomfortable. That's one reason he has agreed to give me a look at what's going on.

His lab and one other discovered how to keep human embryos alive in lab dishes longer than ever before at least 14 days. That has triggered an international debate about a long-standing convention (one that's legally binding in some countries, though not in the U.S.) that prohibits studying human embryos that have developed beyond the two-week stage.

Ali Brivanlou's research team at Rockefeller University in New York was one of two groups internationally that figured out how to keep human embryos alive in lab dishes beyond the 14-day stage of development. Rob Stein/NPR hide caption

And in other experiments, he's using human stem cells to create entities that resemble certain aspects of primitive embryos. Though Brivanlou doesn't think these "embryoids" would be capable of developing into fully formed embryos, their creation has stirred debate about whether embryoids should be subject to the 14-day rule.

Brivanlou says he welcomes these debates. But he hopes society can reach a consensus to permit his work to continue, so he can answer some of humanity's most fundamental questions.

"If I can provide a glimpse of, 'Where did we come from? What happened to us, for us to get here?' I think that, to me, is a strong enough rationale to continue pushing this," he says.

For decades, scientists thought the longest an embryo could survive outside the womb was only about a week. But Brivanlou's lab, and one in Britain, announced last year in the journals Nature and Nature Cell Biology that they had kept human embryos alive for two weeks for the first time.

That enabled the scientists to study living human embryos at a crucial point in their development, a time when they're usually hidden in a woman's womb.

"Women don't even know they are pregnant at that stage. So it has always been a big black box," Brivanlou says.

Gist Croft, a stem cell biologist in Brivanlou's lab, shows me some samples, starting with one that's 12 days old.

"So you can see this with the naked eye," Croft says, pointing to a dish. "In the middle of this well, if you look down, there's a little white speck it looks like a grain of sand or a piece of dust."

Under a microscope, the embryo looks like a fragile ball of overlapping bubbles shimmering in a silvery light with thin hairlike structures extending from all sides.

Croft and Brivanlou explain that those willowy structures are what embryos would normally extend at this stage to search for a place to implant inside the uterus. Scientists used to think embryos could do that only if they were receiving instructions from the mother's body.

"The amazing thing is that it's doing its thing without any information from mom," Brivanlou says. "It just has all the information already in it. That was mind-blowing to me."

The embryos they managed to keep alive in the lab dish beyond seven days of development have also started secreting hormones and organizing themselves to form the cells needed to create all the tissues and organs in the human body.

The two scientists think studying embryos at this and later stages could lead to discoveries that might point to new ways to stop miscarriages, treat infertility and prevent birth defects.

"The only way to understand what goes wrong is to understand what happens normally, or as normally as we can, so we can prevent all of this," Brivanlou says.

The 14-day cutoff

But Brivanlou isn't keeping these embryos alive longer than 14 days because of the rule.

A long-standing rule prohibits scientists from keeping human embryos alive more than two weeks, after which the central nervous system starts to develop. The 14-day rule was developed decades ago to avoid raising too many ethical questions about experimenting on human embryos. It's a law in some countries, and just a guideline in the U.S.

"The decision about pulling the plug was probably the toughest decision I've made in my scientific career," he says. "It was sad for me."

The 14-day rule was developed decades ago to avoid raising too many ethical questions about experimenting on human embryos.

Two weeks is usually the moment when the central nervous system starts to appear in the embryo in a structure known as the "primitive streak."

It's also roughly the stage at which an embryo can no longer split into twins. The idea behind the rule is, that's when an embryo becomes a unique individual.

But the rule was initiated when no one thought it would ever be possible to keep embryos growing in a lab beyond two weeks. Brivanlou thinks it's time to rethink the 14-day rule.

"This is the moment," he says.

Scientists, bioethicists and others are debating the issue in the U.S., Britain and other countries. The rule is law in Britain and other countries and incorporated into widely followed guidelines in the United States.

Insoo Hyun, a bioethicist at Case Western Reserve University, advocates revisiting the rule. It would allow more research to be done on embryos that are destined to be destroyed anyway, he says embryos donated by couples who have finished infertility treatment.

"Given that it has to be destroyed," Hyun says, "some would argue that it's best to get as much information as possible scientifically from it before you destroy it."

But others find it morally repugnant to use human embryos for research at any stage of their development and argue that lifting the 14-day rule would make matters worse.

"Pushing it beyond 14 days only aggravates what is the primary problem, which is using human life in its earliest stages solely for experimental purposes," says Dr. Daniel Sulmasy, a Georgetown University bioethicist.

The idea of extending the 14-day rule even makes some people who support embryo research queasy, especially without first finding another clear stopping point.

Hank Greely, a Stanford University bioethicist, worries that going beyond 14 days could "really draws into question whether we're using humans or things that are well along the path to humans purely as guinea pigs and purely as experimental animals."

Embryo alternative: "Embryoids"

So as that debate continues, Brivanlou and his colleagues are trying to develop another approach. The scientists are attempting to coax human embryonic stem cells to organize themselves into entities that resemble human embryos. They are also using induced pluripotent stem (iPS) cells, which are cells that behave like embryonic stem cells, but can be made from any cell in the body.

Embryoids like this one are created from stem cells and resemble very primitive human embryos. Scientists hope to use them to learn more about basic human biology and development.

Brivanlou's lab has already shown that these "embryo-like structures" or "embryoids" can create the three fundamental cell types in the human body.

But the scientists have only been able to go so far using flat lab dishes. So the researchers are now trying to grow these embryonic-like structures in three dimensions by placing stem cells in a gel.

"Essentially, we're trying to, in a way, to re-create a human embryo in a dish starting from stem cells," says Mijo Simunovic, another of Brivanlou's colleagues.

In early experiments, Simunovic says, he has been able to get stem cells to "spontaneously" form a ball with a "cavity in its center." That's significant because that's what early human embryos do in the uterus.

Simunovic says it's unclear how close these structures could become to human embryos entities that have the capability to develop into babies.

"At the moment, we don't know. That's something that's very hot for us right now to try to understand," Simunovic says.

Simunovic argues the scientists are not "ethically limited to studying these cells and studying these structures" by the 14-day rule.

There's a debate about that, however.

"At what point is your model of an embryo basically an embryo?" asks Hyun, especially when the model seems to have "almost like this inner, budding life."

"Are we creating life that, in the right circumstances, if you were to transfer this to the womb it would continue its journey?" he asks.

Dr. George Daley, the dean of the Harvard Medical School and a leading stem cell researcher, says scientists have been preparing for the day when stem-cell research might raise such questions.

"I think what prospects people are concerned about are the kinds of dystopian worlds that were written about by Aldous Huxley in Brave New World," Daley says. "Where human reproduction is done on a highly mechanized scale in a petri dish."

Daley stresses scientists are nowhere near that, and may never get there. But science moves quickly. So Daley says it's important scientists move carefully with close ethical scrutiny.

The latest guidelines issued by the International Society for Stem Cell Research call for intensive ethical review, Daley notes.

Brivanlou acknowledges that some of his experiments have produced early signs of the primitive streak. But that's a very long way from being able to develop a spinal cord, or flesh and bones, let alone a brain. He dismisses the notion that the research on embryoids would ever lead to scientists creating humans in a lab dish.

"They will not get up start walking around. I can assure you that," he says, noting that full human embryonic development is a highly complex process that requires just the right mix of the biology, physics, geometry and other factors.

Nevertheless, Brivanlou says all of his experiments go through many layers of review. And he's convinced the research should continue.

"It would be a travesty," he says, "to decide that, somehow, ignorance is bliss."

Human 'Embryoids' And Other Embryo Research Raises Concern ... - NPR

Spinal Cord Stem Cells Comments Off on Human ‘Embryoids’ And Other Embryo Research Raises Concern … – NPR | March 2nd, 2017

The mystery of what controls the range of developmental clocks in mammals -- from 22 months for an elephant to 12 days for a opossum -- may lie in the strict time-keeping of pluripotent stem cells for each unique species.

Developmental clocks are of high importance to regenerative medicine, since many cells types take long periods to grow to maturity, limiting their usefulness to human therapies. The regenerative biology team at the Morgridge Institute for Research, led by stem cell pioneer and UW-Madison professor James Thomson, is studying whether stem cell differentiation rates can be accelerated in the lab and made available to patients faster.

In a study published in February online editions of the journal Developmental Biology, Morgridge scientists tested the stringency of the developmental clock in human stem cells during neural differentiation. First, they closely compared the differentiation rates of the cells growing in dishes compared to the known growth rates of human cells in utero. Second, they grew the human stem cells within a mouse host, surrounded by factors -- such as blood, growth hormones and signaling molecules -- endemic to a species that grows much more rapidly than humans.

In both cases -- lab dish or different species -- the cells did not waver from their innate timetable for development, without regard to environmental changes.

"What we found remarkable was this very intrinsic process within cells," said lead author Chris Barry, a Morgridge assistant scientist. "They have self-coding clocks that do not require outside stimulus from the mother or the uterus or even neighboring cells to know their pace of development."

While the study suggests that cellular timing is a stubborn process, the Thomson lab is exploring a variety of follow-up studies on potential factors that could help cells alter their pace, Barry said.

One aspect of the study that's immediately valuable across biology is the realization that how stem cells behave in the dish aligns almost precisely with what happens in nature.

"The promising thing is that we can take species of stem cells, put them in tissue culture, and more confidently believe that events we're seeing are probably happening in the wild as well," Barry said. "That is potentially great news for studying embryology in general, understanding what's going on in the womb and disease modeling for when things can go wrong."

It also opens up potential avenues in embryology that would have been inconceivable otherwise -- for example, using stem cells to accurately study the embryology of whales and other species with much longer (or shorter) gestation rates than humans.

In order to accurately compare development timing across species with wildly different gestation rates -- nine months compared to three weeks -- the team used an algorithm called Dynamic Time Warping, originally developed for speech pattern recognition. This algorithm will stretch or compress the time frame of one species to match up with similar gene expression patterns in the other. Using this process, they identified more than 3,000 genes that regulate more rapidly in mice and found none that regulate faster in human cells.

The impact of solving the cell timing puzzle could be enormous, Barry said. For example, cells of the central nervous system take months to develop to a functional state, far too long to make them therapeutically practical. If scientists can shorten that timing to weeks, cells could potentially be grown from individual patients that could counteract grave diseases such as Parkinson's, Multiple Sclerosis, Alzheimer's, Huntington's disease and spinal cord injuries.

"If it turns out these clocks are universal across different cell types," said Barry, "you are looking at broad-spectrum impact across the body."

Stem cells fiercely abide by innate developmental timing, study ... - Science Daily

Spinal Cord Stem Cells Comments Off on Stem cells fiercely abide by innate developmental timing, study … – Science Daily | March 1st, 2017

SAN CARLOS, Calif., March 1, 2017 /PRNewswire/ --Natera (NTRA), a leader in genetic testing, today announced the upcoming launch of Evercord; a new offering being made commercially available in the second quarter of 2017 that enables expectant parents to collect, store and potentially retrieve their newborn's cord blood and tissue for therapeutic use in transplantation and regenerative medicine applications. Natera aspires to build a different type of national cord blood company, by combining best-in-class cord blood cryopreservation with the company's ability to provide timely information about genetic disease risk; potentially expanding families' stem cell treatment options in the future. Natera will offer Evercord through its leading direct sales channel in the United States.

The Market Potential of Cord Blood Stem Cells Newborn stem cells sourced from umbilical cord blood are known to contain hematopoietic stem cells (HSCs) that can potentially differentiate and regenerate healthy blood and immune systems. Unfortunately, out of the roughly four million births each year in the United States, more than 95% of the cord blood from those births is currently discarded as waste;1 highlighting a significant opportunity both for families who could benefit from cord blood, and for Natera, as it enters the cord blood and tissue banking market. Published data also suggests that one in three people in the United States, or 128million people, could potentially benefit from regenerative medicine applications which, if proven effective, expands the possible therapeutic use of cord blood stem cells.2 More than 300 studies are currently underway, including clinical trials focused on current and new cord blood stem cell therapies in regenerative medicine.3 These trials hold promise for a growing list of conditions, including Alzheimers disease, cerebral palsy, diabetes (Type I/II), spinal cord injury, cartilage and bone repair, and heart defects. More than 30,000 cord blood stem cell treatments have been conducted worldwide and Natera's prenatal tests, including its carrier test, Horizon, currently screen for 35 of the nearly 80 diseases where cord blood stem cell treatment has been administered. Considering the research advances in stem cells and regenerative medicine, it is anticipated that number will, more than likely, continue to grow.

Introducing EvercordThe launch of Evercord is part of a partnership with Bloodworks Northwest, one of the oldest and most reputable public umbilical cord blood banks in the country. Evercord's service will offer expectant families the opportunity to bank their baby's umbilical cord blood and tissue for potential medical use by the child or related family member. Under the terms of the agreement between Natera and Bloodworks, Bloodworks will perform processing and testing services on cord blood samples submitted by Evercord customers and will cryo-preserve the banked cord blood and tissue at its Seattle, Washington-based best-in-class cord blood cryopreservation storage facility. The companies also plan to build a new facility in anticipation of future growth.

The relationship offers several other competitive advantages. Evercord leverages Bloodworks' 20 years of experience processing and banking cord blood; the lab has a strong track record of successfully releasing nearly 1,000 cord blood samples for transplant, more than other leading private cord blood banks.

Once Evercord is commercially launched, it will expand Natera's existing portfolio of women's reproductive health products, further diversifying Natera's revenue base and adding a traditionally high yield business into its product mix. Evercord will also be well positioned to immediately take advantage of Natera's well-established commercial capabilities, including: patient and healthcare provider digital services through Natera's Patient Portal and Natera Connect, and a specialized salesforce that already calls on the nation's busiest obstetrics and gynecology offices and fertility centers.

"At Natera, we believe adding cord blood and tissue banking to our product offerings is a natural extension of our commitment to family health and beyond," said Matt Rabinowitz, CEO and founder of Natera. "Evercord builds on our excellence as a genetic testing company and our mission to transform the diagnosis and management of genetic diseases. Cord blood stem cells have demonstrated regenerative capabilities that medicine is just beginning to learn how to harness; offering a unique opportunity to potentially generate complete genetic information on a human being at the moment of birth. Many of the genetic diseases that cord blood treats today are also conditions that our tests screen for, which could enable us to offer a far more extensive service offering in the future than those offered by leading 'storage-only' cord blood banks today."

About Bloodworks Northwest's Public Cord Blood ProgramBloodworks Northwest partners with hospitals across the region to recover and store umbilical cord blood from new mothers -- an important source of stem cells for use in cancer treatment, metabolic or immune system disorders, and research. Bloodworks Northwest created the first and only public umbilical cord blood bank in the Northwest of the United States and has program partnerships with 15 hospitals across Washington, Oregon and Hawaii providing nearly 50 units per month to the national cord bloodregistry.

About NateraNatera is a genetic testing company that develops and commercializes non-invasive methods for analyzing DNA. The mission of the company is to transform the diagnosis and management of genetic disease. In pursuit of that mission, Natera operates a CAP-accredited laboratory certified under the Clinical Laboratory Improvement Amendments (CLIA) in San Carlos, CA, and it currently offers a host of proprietary genetic testing services primarily to OB/GYN physicians and fertility centers, as well as to genetic laboratories through its cloud-based Constellation software system.

Product offerings include the Spectrum pre-implantation genetic test for embryo selection during IVF; the Anora miscarriage test to understand the genetic causes of a pregnancy loss; the Horizon carrier test to detect inherited mutations; the Panorama non-invasive prenatal test (NIPT) to identify common chromosomal anomalies in a fetus as early as nine weeks of gestation; and Evercord, a cord blood and tissue banking service offered at birth to expectant parents.

Each test described has been developed and its performance characteristics determined by the CLIA-certified laboratory performing the test.

These tests have not been cleared or approved by the U.S. Food and Drug Administration (FDA). Although FDA does not currently clear or approve laboratory-developed tests in the U.S., certification of the laboratory is required under CLIA to ensure the quality and validity of the tests.

Natera is also applying its unique technologies to develop non-invasive screening and diagnostic tools for earlier detection and improved treatment of cancer. These tests have not been cleared or approved by the U.S. Food and Drug Administration.
