Scientists have replicated one of the most significant accomplishments in stem cell research by creating human embryos that were clones of two men.

The lab-engineered embryos were harvested within days and used to create lines of infinitely reproducing embryonic stem cells, which are capable of growing into any type of human tissue.

The work, reported Thursday in the journal Cell Stem Cell, comes 11 months after researchers in Oregon said they had produced the world's first human embryo clones and used them to make stem cells. Their study, published in Cell, aroused skepticism after critics pointed out multiple errors and duplicated images.

In addition, the entire effort to clone human embryos and then dismantle them in the name of science troubles some people on moral grounds.

The scientists in Oregon and the authors of the new report acknowledged that the clones they created could develop into babies if implanted in surrogate wombs. But like others in the field, they have said reproductive cloning would be unethical and irresponsible.

The process used to create cloned embryos is called somatic cell nuclear transfer, or SCNT. It involves removing the nucleus from an egg cell and replacing it with a nucleus from a cell of the person to be cloned. The same method was used to create Dolly the sheep in 1996, along with numerous animals from other species.

Human cloning was a particular challenge, in part because scientists had trouble getting enough donor eggs to carry out their experiments. Some scientists said SCNT in humans would be impossible.

Dr. Robert Lanza, the chief scientific officer for Advanced Cell Technology Inc. in Marlborough, Mass., has been working on SCNT off and on for about 15 years. He and his colleagues finally achieved success with a modified version of the recipe used by the Oregon team and skin cells donated by two men who were 35 and 75.

After swapping out the nucleus in the egg cell, both groups used caffeine to delay the onset of cell division a technique that has been called "the Starbucks effect." But instead of waiting 30 minutes to prompt cell division, as was done in the Oregon experiment, Lanza and his team waited two hours.

After years of failed attempts, researchers have finally generated stem cells from adults using the same cloning technique that produced Dolly the sheep in 1996.

A previous claim that Korean investigators had succeeded in the feat turned out to be fraudulent. Then last year, a group at Oregon Health & Science University generated stem cells using the Dolly technique, but with cells from fetuses and infants.

In this case, cells from a 35-year-old man and a 75-year-old man were used to generate two separate lines of stem cells. The process, known as nuclear transfer, involves taking the DNA from a donor and inserting it into an egg that has been stripped of its DNA. The resulting hybrid is stimulated to fuse and start dividing; after a few days the embryo creates a lining of stem cells that are destined to develop into all of the cells and tissues in the human body. Researchers extract these cells and grow them in the lab, where they are treated with the appropriate growth factors and other agents to develop into specific types of cells, like neurons, muscle, or insulin-producing cells.

Reporting in the journal Cell Stem Cell, Dr. Robert Lanza, chief scientific officer at biotechnology company Advanced Cell Technology, and his colleagues found that tweaking the Oregon teams process was the key to success with reprogramming the older cells. Like the earlier team, Lanzas group used caffeine to prevent the fused egg from dividing prematurely. Rather than leaving the egg with its newly introduced DNA for 30 minutes before activating the dividing stage, they let the eggs rest for about two hours. This gave the DNA enough time to acclimate to its new environment and interact with the eggs development factors, which erased each of the donor cells existing history and reprogrammed it to act like a brand new cell in an embryo.

The team, which included an international group of stem cell scientists, used 77 eggs from four different donors. They tested their new method by waiting for 30 minutes before activating 38 of the resulting embryos, and waiting two hours before triggering 39 of them. None of the 38 developed into the next stage, while two of the embryos getting extended time did. There is a massive molecular change occurring. You are taking a fully differentiated cell, and you need to have the egg do its magic, says Lanza. You need to extend the reprogramming time before you can force the cell to divide.

While a 5% efficiency may not seem laudable, Lanza says that its not so bad given that the stem cells appear to have had their genetic history completely erased and returned to that of a blank slate. This procedure works well, and works with adult cells, says Lanza.

The results also teach stem cell scientists some important lessons. First, that the nuclear transfer method that the Oregon team used is valid, and that with some changes it can be replicated using older adult cells. It looks like the protocols we described are real, they are universal, they work in different hands, in different labs and with different cells, says Shoukhrat Mitalopov, director of the center for embryonic cell and gene therapy at Oregon Health & Science University, and lead investigator of that study.

Researchers Clone Cells From Two Adult Men

Tissue engineering has been used to construct natural oesophagi, which in combination with bone marrow stem cells have been safely and effectively transplanted in rats. The study, published in Nature Communications, shows that the transplanted organs remain patent and display regeneration of nerves, muscles, epithelial cells and blood vessels.

The new method has been developed by researchers at Karolinska Institutet in Sweden, within an international collaboration lead by Professor Paolo Macchiarini. The technique to grow human tissues and organs, so called tissue engineering, has been employed so far to produce urinary bladder, trachea and blood vessels, which have also been used clinically. However, despite several attempts, it has been proven difficult to grow tissue to replace a damaged esophagus.

In this new study, the researchers created the bioengineered organs by using oesophagi from rats and removing all the cells. With the cells gone, a scaffold remains in which the structure as well as mechanical and chemical properties of the organ are preserved. The produced scaffolds were then reseeded with cells from the bone marrow. The adhering cells have low immunogenicity which minimizes the risk of immune reaction and graft rejection and also eliminates the need for immunosuppressive drugs. The cells adhered to the biological scaffold and started to show organ-specific characteristics within three weeks.

The cultured tissues were used to replace segments of the esophagus in rats. All rats survived and after two weeks the researchers found indications of the major components in the regenerated graft: epithelium, muscle cells, blood vessels and nerves.

"We believe that these very promising findings represent major advances towards the clinical translation of tissue engineered esophagi," says Paolo Macchiarini, Director of Advanced center for translational regenerative medicine (ACTREM) at Karolinska Institutet.

Tissue engineered organs could improve survival and quality of life for the hundreds of thousands of patients yearly diagnosed with esophageal disorders such as cancer, congenital anomalies or trauma. Today the patients' own intestine or stomach is used for esophageal replacements, but satisfactory function rarely achieved. Cultured tissue might eliminate this current need and likely improve surgery-related mortality, morbidity and functional outcome.

Regenerated esophagus transplanted in rats

Beverly Hills, CA (PRWEB) April 14, 2014

Top Los Angeles and Beverly Hills orthopedic surgeon, Dr. Raj, is now working with R3 Stem Cell at his Beverly Hills Orthopedic Institute to offer comprehensive regenerative medicine treatment. The stem cell procedures for shoulder, knee, and hip conditions typically work great for degenerative arthritis, tendonitis, and ligament injuries. For more information and scheduling with the top stem cell clinic in LA and Beverly Hills, call (310) 438-5343.

Dr. Raj treats athletes, celebrities, executives, grandparents, and everything in between. Oftentimes, the stem cell procedures are able to help athletes heal tendon and ligament injuries quickly, without surgery and get back to competition quickly. In addition, the stem cell procedures work well the majority of the time for degenerative arthritis of the hip, knee, and shoulder.

The stem cell material is either bone marrow derived from the patient or comes from amniotic fluid. The bone marrow derived stem cell injections are performed as an outpatient procedure. The bone marrow is harvested from the patient, immediately processed, and then injected into the problem area. The processing concentrates the stem cells and growth factors to increase the potential for repair and regeneration.

The amniotic fluid derived stem cells have been used tens of thousands of times around the world with no adverse events being reported, with the fluid being processed at an FDA regulated lab. The fluid contains stem cells, hyaluronic acid and growth factors to help repair damaged cartilage and injured tendons and ligaments. This can help patients avoid surgery for rotator cuff tendonitis and tears, elbow tendonitis, achilles tears, knee injuries and joint arthritis.

Dr. Raj is Double Board Certified and sees patients from the greater Los Angeles and Beverly Hills area. Numerous times, he has been named one of Los Angeles top orthopedic doctors, while also acting as an ABC News Medical Correspondent.

'This is groundbreaking for the entire field and offers a new outlook that the spinal cord, even after a severe injury, has great potential for functional recovery'

PARIS, France Scientists on Tuesday, April 8 reported progress in a technique to stimulate the lower spinal cord in paraplegics to help them recover lost nerve function.

Cautiously tested on a single patient 3 years ago, the technique has been trialed on 3 other young men who had been paraplegic for at least two years after road accidents, they said.

After the patients were given an implant to stimulate nerve bundles in the lower spine, they were able to voluntarily flex their knees and shift their hips, ankles and toes, the team reported in a published study.

The 4 were not able to walk but could bear some weight independently -- a key phase towards this goal -- and experienced a "dramatic" improvement in wellbeing, they added.

Claudia Angeli of the University of Louisville's Kentucky Spinal Cord Injury Research Center (KSCIRC) said two of the men had been diagnosed not only as paralysed in the legs, but also lacking lower-body sensation, with no chance of recovery.

"This is groundbreaking for the entire field and offers a new outlook that the spinal cord, even after a severe injury, has great potential for functional recovery," Angeli said in a press release.

Paralysis comes from damage to the spinal cord down which the brain sends electrical signals along nerve fibers to instruct limb movement.

Decades of experimental effort have been devoted to reconnecting severed fibers through surgery or regrowing them through drugs or stem cells.

A new way to artificially control muscles using light, with the potential to restore function to muscles paralyzed by conditions such as motor neuron disease and spinal cord injury, has been developed by scientists at UCL and King's College London.

The technique involves transplanting specially-designed motor neurons created from stem cells into injured nerve branches. These motor neurons are designed to react to pulses of blue light, allowing scientists to fine-tune muscle control by adjusting the intensity, duration and frequency of the light pulses.

In the study, published this week in Science, the team demonstrated the method in mice in which the nerves that supply muscles in the hind legs were injured. They showed that the transplanted stem cell-derived motor neurons grew along the injured nerves to connect successfully with the paralyzed muscles, which could then be controlled by pulses of blue light.

"Following the new procedure, we saw previously paralyzed leg muscles start to function," says Professor Linda Greensmith of the MRC Centre for Neuromuscular Diseases at UCL's Institute of Neurology, who co-led the study. "This strategy has significant advantages over existing techniques that use electricity to stimulate nerves, which can be painful and often results in rapid muscle fatigue. Moreover, if the existing motor neurons are lost due to injury or disease, electrical stimulation of nerves is rendered useless as these too are lost."

Muscles are normally controlled by motor neurons, specialized nerve cells within the brain and spinal cord. These neurons relay signals from the brain to muscles to bring about motor functions such as walking, standing and even breathing. However, motor neurons can become damaged in motor neuron disease or following spinal cord injuries, causing permanent loss of muscle function resulting in paralysis

"This new technique represents a means to restore the function of specific muscles following paralysing neurological injuries or disease," explains Professor Greensmith. "Within the next five years or so, we hope to undertake the steps that are necessary to take this ground-breaking approach into human trials, potentially to develop treatments for patients with motor neuron disease, many of whom eventually lose the ability to breathe, as their diaphragm muscles gradually become paralyzed. We eventually hope to use our method to create a sort of optical pacemaker for the diaphragm to keep these patients breathing."

The light-responsive motor neurons that made the technique possible were created from stem cells by Dr Ivo Lieberam of the MRC Centre for Developmental Neurobiology, King's College London.

"We custom-tailored embryonic stem cells so that motor neurons derived from them can function as part of the muscle pacemaker device." says Dr Lieberam, who co-led the study. "First, we equipped the cells with a molecular light sensor. This enables us to control motor neurons with blue light flashes. We then built a survival gene into them, which helps the stem-cell motor neurons to stay alive when they are transplanted inside the injured nerve and allows them to grow to connect to muscle."

Dr. Jeffrey Adler, New York podiatrist and Owner/Medical Director of Adler Footcare New York, will be interviewed by radio personality Laura Smith and taking live calls on New York talk show 77 WABC about the use of stem cells to treat chronic foot pain.

Adler Footcare New York uses live birth stem cells to help treat patients with chronic foot problems such as: Plantar fasciitis, Osteoarthritis, Achilles tendonitis and torn soft tissue. The stem cell treatment is proving to be much more effective than traditional treatments like physical therapy or orthotic therapy.

Stem cells have the ability to replicate themselves or change into the cell type that is needed to repair damaged tissue. The therapy works by directly introducing live stem cells into the affected area causing pain. Its approved by the FDA and consistently reviewed by medical professionals to remove the potential of any communicable diseases.

Dr. Adler often travels to other states to share his knowledge with other doctors in his profession. His latest research on stem cell therapy has gained much interest among his peers in the medical industry.

When compared to traditional treatments, stem therapy is proving to be more successful and longer lasting, Dr. Adler said. We are seeing patients heal much quicker and return to their normal activities much sooner.

To learn more about stem cell replacement therapy or to schedule a consultation with a New York podiatrist at Adler Footcare, call (212) 704-4310 or visit http://www.mynycpodiatrist.com.

About Adler Footcare New York Dr. Jeffrey L. Adler, Medical/Surgical Director and owner of Adler Footcare New York has been practicing podiatric medicine since 1979 and has performed thousands of foot and ankle surgeries. Dr. Adler is board certified in Podiatric Surgery and Primary Podiatric Medicine by the American Board of Multiple Specialties in Podiatry. Dr. Adler is also a Professor of Minimally Invasive Foot Surgery for the Academy of Ambulatory Foot and Ankle Surgeons. As one of only several in the country who perform minimally invasive podiatric surgery, Dr. Adlers patients enjoy significantly reduced recovery times.

Viruses were traditionally thought to be malicious nanoscopic bearers of death and destruction. But modern science has suggested that while that is sometimes the case, the relationship between viruses and living organisms is a complicated one, as is the question of whether viruses can be truly considered "living" organisms. I. Viruses Can Actually be Useful, Sometimes In case newly discovered mega-viruses -- which rival small bacteria in size, function, and genetic complexity (and are sometimes "infected" by other viruses) -- aren't mind-warping enough, recent evidence suggests that as much of 8 percent of the genetic material found in higher organisms such as humans may be "borrowed" from viral genomes. These pieces of DNA are identifiable, if you know what you're looking for, but long ago lost their ability to depart and jump to new hosts. In that regard, mankind can be viewed as similar in some ways to lichen -- as a collection of multiple fused "organisms" living as one -- as modern man's genetic code consists of virus and traditional eukaryotic genes functioning side by side. The latest wild discovery comes courtesy of Montreal, Quebec, Canada's McGill University.

Professor Bourque states in an interview with National Geographic:

[Acquiring useful genes from viruses] can be faster than just relying on random mutations to get something that might work.

[These genes should be examined] to see if they have also evolved new functional roles, like HERV-H did in stem cells. We suspect that these genes may play important roles in other cell types as well, such as liver, kidney, and brain.

When someone has chronic venous insufficiency, it means that because of faulty valves in their leg veins, oxygen-poor blood isn't able to be pumped back to their heart. The George Washington University's Dr. Narine Sarvazyan has created a possible solution, however a beating "mini heart" that's wrapped around the vein, to help push the blood through.

The mini heart takes the form of a cuff of rhythmically-contracting heart tissue, made by coaxing the patient's own adult stem cells into becoming cardiac cells. When one of those cuffs is placed around a vein, its contractions aid in the unidirectional flow of blood, plus it helps keep the vein from becoming distended. Additionally, because it's grown from the patient's own cells, there's little chance of rejection.

So far, the cuffs have been grown in the lab, where they've also been tested. Soon, however, Sarvazyan hopes to conduct animal trials, in which the cuffs are actually grown on the vein, in the body.

"We are suggesting, for the first time, to use stem cells to create, rather than just repair damaged organs," she said. "We can make a new heart outside of ones own heart, and by placing it in the lower extremities, significantly improve venous blood flow."

Scientists at Germany's Fraunhofer Institute for Manufacturing Engineering and Automation are also working on a treatment for chronic venous insufficiency, although their approach has been to create artificial venous valves that could be used to replace the defective natural ones.

A paper on Sarvazyan's research was recently published in the Journal of Cardiovascular Pharmacology and Therapeutics. One of the mini hearts can be seen beating away, in the video below.

Researchers have grown embryonic-like stem cells from patients with bipolar disorder and transformed them into brain cells that are already answering questions about the condition.

The cells, which carry the precisely tailored genetic instructions from the patients own cells, behave differently than cells taken from people without the disorder, the researchers report.

Already, we see that cells from people with bipolar disorder are different in how often they express certain genes, how they differentiate into neurons, how they communicate, and how they respond to lithium," Sue O'Shea, a stem cell specialist at the University of Michigan who led the study, said in a statement.

The work, described in the journal Translational Psychiatry, helps fulfill one of the big promises of stem cells research using a patients own cells to study his or her disease.

Mental illness is especially hard to study. Getting into a living persons brain is almost impossible, and scientists cant deliberately cause it in people in order to study it.

Creating animals such as mice with what looks like human mental illness is imprecise at best.

The University of Michigan team turned instead to what are called induced pluripotent stem cells, or iPS cells. These are ordinary skin cells taken from a patient and tricked into turning back into the state of a just-conceived embryo.

These cells, grown from skin cells taken from people with bipolar disorder, arose from stem cells and were coaxed to become neural progenitor cells -- the kind that can become any sort of nervous system cell. The research showed differences in cell behavior compared with cells grown from people without bipolar disorder.

They are pluripotent, meaning they can become any type of cell there is. In this case, the Michigan team redirected the cells to become neurons the cells that make up much of the brain. "This gives us a model that we can use to examine how cells behave as they develop into neurons, OShea said.

Bipolar disorder, once called manic-depression, is very common, affecting an estimated 3 percent of the population globally. It runs in families, suggesting a strong genetic cause, and is marked by mood swings from depression to feelings of euphoria and creativity thats considered the manic phase.

Children being treated for blood cancer at Medical University Hospital will get a taste of hope Thursday.

A 5k run to raise awareness of the need for bone marrow donations is set for Saturday. The children are not strong enough to participate in that. So a Tot Run will be held on their hospital floor Thursday morning.

Several dozen children, their families and staff will run around the oncology floor as they are able from 11 a.m. to noon, said Ashley Collier, community representative for Be The Match, the state's bone marrow bank.

"It's a way the children to be involved," she said.

For every child that gets a bone marrow transplant, two more don't get one because a matching donor can't be found, Collier said.

The Match to Marrow 5K Run starts at 9 a.m. Saturday at Wannamaker County Park in North Charleston. The entry fee is $25. Representatives will also be on hand to explain how to donate blood from which stem cells for bone marrow are harvested.

Newswise MADISON, Wis. Desperate patients are easy prey for unscrupulous clinics offering untested and risky stem cell treatments, says law and bioethics Professor Alta Charo of the University of Wisconsin-Madison, who is studying stem cell tourism.

Stem cells are cells that can form many types of cells in the body, and that makes them inherently promising and dangerous. Stem cell tourism refers to people traveling, both within the U.S. and abroad, in pursuit of advertised stem cell therapies to purportedly treat a variety of medical conditions.

The evidence for therapeutic use of stem cells is very limited, except for bone marrow stem cells, but patients all over the world are convinced stem cells will cure their disease, says Charo. While there are some very promising results in the early clinical trials for stem cell therapies using embryonic and other kinds of stem cells, the treatments being advertised by these clinics are dubious, mostly ineffective, and sometimes positively harmful.

Patients are being hoodwinked, but there are dilemmas about tackling (the treatments) at regulatory or political levels.

The outrage over failures in stem cell tourism is limited, Charo says. Patients may pay tens of thousands of dollars for procedures that may carry no promise of success or carry grievous risks of failure. Most people have no reason to pay attention, and those who are paying attention are sick, so they are focused on trying anything, Charo says. If it does not work, they are already in a bad position with plenty to think about.

During a search for stem cell therapies on the web, Charo found products that supposedly enhance the natural formation of stem cells in the skin alongside approved and unapproved treatments in the United States, and stem cell clinics outside the United States, like a stem cell treatment for spinal conditions that might be innocuous, but is probably useless.

Some American operators are trying to slip through Food and Drug Administration regulation, says Charo, who served as senior policy advisor in the Office of the Commissioner of the FDA between 2009 and 2011. The FDA regulates medical devices, tissue transplants and drugs, but not organ transplants or the way medicine is practiced.

To sell a product that can heal without claiming it is a drug, some clinics remove stem cells from a patient, grow them with minimal manipulation, and then reinsert the resulting cells back to the same patient. There has been a long-running battle over whether that is a tissue transplant akin to organ transplantation and thus the practice of medicine, or a tissue transplant that is acting like drug, Charo says. If the latter, then what you do is subject to FDA [regulation], so you have to prove that your product is safe and effective, which almost always requires expensive clinical trials.
