Siriraj hospital doctors, that the discovery of stem cells

Faculty of medicine Siriraj hospital hospital said yesterday that succeeded it by creating the world's first pure stem cells from human amniotic fluid.

Dr. Charnchai Wanthanasiri, head of the Department of obstetrics, said that stem cells derived from the human body often have limitations, because researchers are usually able to take so much tissue organs development of cell cultures relevant research.

Dr. Charnchai said the Department provides services to birth and used tissues from umbilical cords and placentas of the delivery process. Provided the Department with suitable material in order to carry out research on stem cells.

Dr. Supakdi Julwichitpong, head of research, stem cell therapy, said that the results will be used to combat disease neuro degenerative conditions such as Alzheimer's and Parkinson 's.

Dr. Thassanee Permthai, a researcher for the breakthrough, said that stem cells from amniotic fluid may be grown on several cell types of the body. Stem cells have a high degree of purity, are very fast and can be stored for a long time. They can be prepared quickly, using a new technique that is more efficient.

Stem cell research shows promise

Now researchers at the New York stem cell Foundation, the laboratory developed a method that can help to recover lost ground.

Embryonic stem cells can generate all the tissues of the body. So if these cells can be developed from the cells of adult patient, it may be possible to make replacement cells for every patient tissue without fear of rejection.

At first it seemed that stem cells can be made of implantation of the nuclei of adult patient in an unfertilized human egg, or oocyte, whose nucleus has been removed. Mysterious factors in the body of the egg to adult cells to lose its specialist nature and back in its infancy where all fate open to him.

However, this method is highly inefficient and will require dozens or hundreds of eggs for each patient. A major step forward was made in 2007, when Shinya Yamanaka found a way to avoid using human eggs.

He guessed oocyte reprograms the inserted nucleus and showed that by injecting protein factors in only four cells of the adult patient, he could make it back to an embryonic State. Cells made by Dr. Yamanaka, called induced pluripotent stem cells, or iPS cells. At first it seemed they are identical as hoped, embryonic cells made using the oocytes.

But as researchers examine them more closely, they found more and more anomalies, making the cells unsuitable for therapeutic use. In particular, iPS cells seem to preserve the memory, in the form of chemical signals in the material, which drives their DNA, their previous personality. This trace memory to prevent them from morphing into other types of cells when needed.

The team led by Scott Noggle and Dieter Egli, New York stem cell Foundation, now back to the basics, trying to improve on an original method of using eggs to create patient-derived embryonic stem cells.

Happy coincidence, as part of the management of the experiment they left the egg nucleus in place when they implanted the adult nucleus. They noticed that in the presence of a nucleus of ova, embryos from adult cell nucleus inserted developed much further than usual. They progressed, in fact, the blastocyst stage, the point at which embryonic stem cells can be collected, researchers report in Wednesday's issue of nature.

With several species including mice and cow cells to easily reach the blastocyst stage, and from there a donor you can clone when the blastocyst is implanted in the uterus. But despite all the worry about the cloning of people, in fact, it was nearly impossible to coax human eggs with the implanted nucleus to move to the stage of blastocysts. New York researchers say that they have not been able to repeat a claim that has been published.

Blastocysts, produced by New York triploidnyj, means that they have a normal diploid genome, or double inserted adults cells plus one oocyte genome. Triploidnyj cells are unstable and potentially cancerous and can never be put into patients. In addition, this process is too inefficient for therapeutic use is 63 oocytes were required to create a single normal set of embryonic cells.

"These cells are not therapeutically appropriate at this time," Dr. Noggle said.

Their relevance for research to study the process of the development of the blastocyst, and in particular to examine why the iPS cells is made by Dr. Yamanaka is reprogrammed. It may be that in addition to the four identified Dr. Yamanaka requires other factors. If these were to be identified, iPS cells can be put back on track as a starting point for therapy. Will remain the many difficult steps, like ensuring that the cells, which are created to restore the patient's tissues are programmed correctly, well behaved and benign.

Dr. Noggle and Dr. Egli also hope to adapt their way of getting useful blastocysts, the patient received. If the core of the human egg too early, it probably does not provide enough of the factors necessary to reprogram the nucleus. If it is after the first cell division, it merges with the inserted nucleus and can not be removed. You may be able to yank it at the last possible minute, when he made enough reprogramming job, and get a normal diploid blastocysts are formed from cells of the patient.

Research stands as a stepping stone to success, "Dr. George q. Daley, a stem cell expert at children's Hospital Boston, writes in a commentary in nature. He also calls "the provocative question," he said, of whether the patient received embryonic cells, made the old-fashioned way with ova can work better than the iPS cells.

Researchers from the New York stem cell Foundation, has the advantage of access to abundant oocytes because they worked with Columbia University program, which pays donors $ 8000. Many ethicists fear that payments to donors will lead to a market in organs, and they hoped that enough oocytes will be donated for free. The National Academy of Sciences has published guidelines for stem cell research, saying that donors should not be paid.

But oocyte donation is a difficult process, and stem cell researchers in many countries have been unable to find enough volunteers for their experiments to proceed. Starting in 2009, the State of New York has allowed donors to receive reasonable compensation for eggs donated for stem cell research.

Artificial cornea gives the gift of vision

AppId is over the quota
AppId is over the quota
corner top left block corner top right October 05, 2012

Blindness is often caused by corneal diseases. The established treatment is a corneal transplant, but in many cases this is not possible and donor corneas are often hard to come by. In the future, an artificial cornea could make up for this deficiency and save the vision of those affected.

Our eyes are our window to the world. Thousands of people have lost their eyesight due to damages to the cornea, such as trauma, absent limbal stem cells or diseases. Transplantation of a donor cornea is the therapy of choice for a great number of those patients. Let alone the issue of scarce donor material, a sub-group of patients do not tolerate transplanted corneas, necessitating the employment of an alternative means of restoring eye sight. In Germany alone, around 7,000 patients are waiting to be treated. In close cooperation with the Aachen Centre of Technology Transfer, Dr. Storsberg and his team from the Fraunhofer Institute for Applied Polymer research IAP in Potsdam, are attempting to improve the situation by developing an artificial cornea. Scientific partners in the "ART CORNEA" project include the Martin Luther University of Halle-Wittenberg, ACTO e. V. and the Ophthalmic Clinic Cologne-Merheim.

"We are in the process of developing two different types of artificial corneas. One of them can be used as an alternative to a donor cornea in cases where the patient would not tolerate a donor cornea, let alone the issue of donor material shortage," says IAP project manager Dr. Joachim Storsberg. The scientist has considerable expertise in developing and testing of next-generation biomaterials. Between 2005 and 2009 he collaborated with interdisciplinary teams and private companies to successfully develop an artificial cornea specifically for patients whose cornea had become clouded - a condition that is extremely difficult to treat. Such patients are unable to accept a donor cornea either due to their illness or because they have already been through several unsuccessful transplantation attempts. Dr. Storsberg was awarded the Josef-von-Fraunhofer Prize 2010 for this achievement. "A great many patients suffering from a range of conditions will be able to benefit from our new implant, which we've named ArtCornea®. We have already registered ArtCornea® as a trademark," reports Storsberg.

Ultima ratio patients regain vision

ArtCornea® is based on a polymer with high water-absorbent properties. Dr. Storsberg and his team have added a new surface coating to ensure anchorage in host tissue and functionality of the optic. The haptic edge was chemically altered to encourage local cell growth. These cells graft to the surrounding human tissue, which is essential for anchorage of the device in the host tissue. The researchers aimed to enlarge the optical surface area of the implant in order to improve light penetration beyond what had previously been possible - a tall order. "Once ArtCornea® is in place, it is hardly visible, except perhaps for a few stitches. It's also easy to implant and doesn't provoke any immune response," says Storsberg, highlighting the merits of this new development.

The specialists have also managed to make a chemically and biologically inert base material biologically compatible for the second artificial cornea, ACTO-TexKpro. Dr. Storsberg achieved this by selectively altering the base material, polyvinylidene difluoride, by coating the fluoride synthetic tissue with a reactive molecule. This allows the patient's cornea to bond together naturally with the edge of the implant, while the implant's inner optics, made of silicon, remain free of cells and clear. The ACTO-TexKpro is par-
ticularly suitable as a preliminary treatment, for instance if the cornea has been destroyed as a consequence of chronic inflammation, a serious accident, corrosion or burns.

The experiments were carried out in collaboration with Dr. Norbert Nass and Dr. Saadettin Sel, Senior consultant ophthalmologist at Martin-Luther-University Halle-Wittenberg. How well TexKpro and ArtCornea® are accepted by clinicians as an additional tool at their disposal was first tested by the doctors in the laboratory thereafter in vivo in several rabbits. After a six month healing process, the implanted prostheses were accepted by the rabbits without irritation, clearly and securely anchored within the eye. Tests carried out following the operation showed that the animals tolerated the artificial cornea well. Prof. Dr. Norbert Schrage will take charge of clinical trials that will soon commence at the Eye Clinic Cologne-Merheim. It is likely that the positive results of tests carried out thus far will be confirmed, and the co-operation partners rate the chances of success very highly. Their optimism is well founded: As early as 2009, several Ultima-Ratio patients received implants of a Kerato prosthesis specially developed for them because they had previously rejected human corneas. These patients have not suffered any complications and are still wearing their artificial corneas today.


Synthetic eye prosthesis
Donor corneas are a rarity: In Germany alone, each year roughly 7,000 patients wait for that miniscule piece of tissue. An implant made of plastic may soon offer patients - especially those facing their last resort - with the chance to see again.

Corneal transplant technique shows promise in children
For infants and children with blinding diseases of the cornea, a sophisticated new corneal transplantation technique offers the hope of improving vision while overcoming the technical difficulty and low success rate of traditional penetrating keratoplasty (PK) in children, according to reports in the current issue of the Journal of AAPOS (American Association for Pediatric Ophthalmology and Strabismus).

Artificial cornea offers better results for infants, some blind patients
Infants and adults who are blind due to a cloudy or damaged cornea are seeing some remarkable results thanks to a new version of an artificial implant that takes the place of the cornea, the clear covering of the eye that serves as our window on the world.

An artificial cornea is in sight, thanks to biomimetic hydrogels
If eyes are "the windows of the soul," corneas are the panes in those windows. They shield the eye from dust and germs. They also act as the eye's outermost lens, contributing up to 75 percent of the eye's focusing power.

Artificial sight
An engineering team at the University of Dundee has just secured funding to work with European colleagues on the construction of artificial corneas which will allow all cornea replacements to go ahead without the patient having to wait for a donor. The Euro 2.4m project will help people who suffer from a number of diseases requiring corneal grafting including keratoconus - a thinning of the cornea. Instead of relying on donor corneas from an eye bank, the new technology invented by biochemists, tissue engineers and structural engineers will allow the European team to grow the cornea from human stem cells in a test tube.

Dynamics of DNA packaging helps regulate formation of heart

AppId is over the quota
AppId is over the quota
corner top left block corner top right September 28, 2012

Findings hold promise for heart regeneration and understanding congenital heart defects

A new regulator for heart formation has been discovered by studying how embryonic stem cells adjust the packaging of their DNA. This approach to finding genetic regulators, the scientists say, may have the power to provide insight into the development of any tissue in the body - liver, brain, blood and so on.

A stem cell has the potential to become any type of cell. Once the choice is made, the cell and other stem cells committed to the same fate divide to form organ tissue.

A University of Washington-led research team was particularly interested in how stem cells turn into heart muscle cells to further research on repairing damaged hearts through tissue regeneration. The leaders of the project were Dr. Charles Murry, a cardiac pathologist and stem cell biologist; Dr. Randall Moon, who studies the control of embryonic development, and Dr. John Stamatoyannopoulos, who explores the operating systems of the human genome.

The paper's lead author is Dr. Sharon Paige, a UW MD-PhD student who completed her Ph.D. in Dr. Murry's lab.

The results are published in the Sept. 28 edition of Cell.

Paige, an aspiring pediatric cardiologist, said, "By identifying regulators of cardiac development, this work has the potential to lead to a better understanding of the causes of congenital heart disease, thereby paving the way for therapeutic advances."

Previously UW researchers had examined the signals that prod cells to grow into various kinds of heart tissue. In this case, the researchers entered a relatively unexplored area. They decided to look at the genetic controls behind the transformation of stem cells into heart tissue.

Because stem cells keep their DNA code under wraps until needed, the scientists examined how this packaging is altered over time to permit reading of portions of the code and thereby produce changes in the cell.

DNA is wound up into a structure called chromatin. "DNA can be packaged as tightly closed, neutral or activated," Murry explained. The tightly closed state, he said, is analogous to setting the brakes on a car.

Like a child who clams up when asked, "What will you be when you grow up?" stem cells are protective of the genes that will determine their future cell type, or what scientists call their cell fate.

"We found that stem cells take great care to avoid turning on cell-fate regulating genes at the wrong time," Murry said. "These genes have their brakes on until they are needed." When the time is right, he said, "the brakes come off and the gas goes on."

He explained that the situation is different for genes that regulate cell functions, in contrast to those that regulate cell fate. Genes that control, for example, the production of proteins that allow the cell to contract or to generate electrical signals do not have such a complex braking system. Those genes can be more readily activated.

The researchers pointed out that it was already known that the patterns stem cells follow to modify their DNA packaging distinguished them from progenitor cells - cells prepared to begin a lineage of a particular type of cell - and also from cells that already had a working identity, such as blood or muscle cells.

However , the dynamics of the DNA packaging modifications - how the packaging is programmed to change over time-and how these dynamics influence which genes are "exposed" and activated to create, for example, heart muscle cells, was poorly understood.

The UW-led research team learned that, as human embryonic stem cells become heart cells, this differentiation is accompanied by distinctive dynamic alterations in DNA packaging. This tell-tale pattern enabled the scientists to distinguish the key regulators of heart development from other genes. The researchers referred to the carefully timed pattern of changes in the DNA wrapping as a "temporal chromatin signature."

Just as a bank robber leaves incriminating evidence in a handwritten note to the teller, the temporal chromatin signature gave the scientists the clues they needed to hunt down new genes that might be responsible for heart formation.

"We found a bunch of them," Murry said. Their system revealed the top candidate to be the homebox gene MEIS2. This gene seemed an unlikely choice because it had no previous record of participating in heart formation. However, when this gene was removed from a new generation of zebra fish, the developing fish embryos had heart tube formation defects and other heart abnormalities.

Murry and other members of the research team think patterns in DNA unwrapping could be broadly applicable to discovering the genes that regulate other aspects of tissue and organ formation beyond only the heart. Such a research approach might help reveal the major developmental decisions that occur inside of cells as an embryo forms and grows. These revelations could provide information useful to spurring stem cells to form specific tissues for organ repair later in life.

Acknowledging the limitations of a lab system in mimicking what happens inside living cells in the early stages of organ formation in humans, Murry said, "The use of the temporal chromatin signature to discover regulatory genes could give us new insights into human development and new tools to control cell fate."

In the past decades our understanding of stem cell biology has increased tremendously. Many types of stem cells have been discovered in tissues of which everyone presumed were unable to regenerate in adults; these include particularly the heart and the brain. There is vast interest in stem cells from biologists and clinicians who see the potential for regenerative medicine and future treatments for chronic diseases like Parkinson, diabetes and spinal cord lesions based on the use of stem cells and entrepreneurs in biotechnology who expect new commercial applications ranging from drug discovery to transplantation therapies. As is often the case in science, many early claims turned out to be different from those expected. Embryonic stem cell therapies have not moved rapidly into clinical...

Animal research shows promise for treating Alzheimer's disease, brain damage, and heart problems resulting from spinal cord injuries

NEW ORLEANS - New animal studies provide additional support for investigating stem cell treatments for Parkinson's disease, head trauma, and dangerous heart problems that accompany spinal cord injury, according to research findings released today. The work, presented at Neuroscience 2012, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health, shows scientists making progress toward using stem cell therapies to repair neurological damage.

The studies focused on using stem cells to produce neurons - essential, message-carrying cells in the brain and spinal cord. The loss of neurons and the connections they make for controlling critical bodily functions are the chief hallmarks of brain and spinal cord injuries and of neurodegenerative afflictions such as Parkinson's disease and ALS (amyotrophic lateral sclerosis), also known as Lou Gehrig's disease.

Today's new findings show that:

- Neurons derived from human embryonic stem cells implanted in monkeys displaying symptoms of Parkinson's disease appear to have matured into healthy, dopamine-producing neurons without causing any adverse effects (Dustin Wakeman, PhD, abstract 314.11, see attached summary).

- Life-threatening heart problems caused by spinal cord injury were partially remedied in rats treated with stem cells derived from the fetal brainstem. The findings suggest new avenues of research for repairing cardiovascular damage in human patients with spinal cord injuries (Armin Blesch, PhD, abstract 637.10, see attached summary).

- Experiments in mice indicate it may be possible to activate dormant stem cells in the adult prompting the production of new neurons that might help repair damage caused by injury (Nathaniel Hartman, PhD, abstract 823.07, see attached summary).

Other recent findings discussed show that:

- Scientists believe they have isolated a protein that can signal the adult brain to produce more neurons, raising the possibility that boosting production of the protein could help patients recover neurons lost to degenerative diseases like Parkinson's and ALS, or to trauma, such as spinal cord injury (Anthony Conway, abstract 823.04, see attached speaker's summary).

"As the fields of developmental and regenerative neuroscience mature, important progress is being made to begin to translate the promise of stem cell therapy into meaningful treatments for a range of well-defined neurological problems," said press conference moderator Jeffrey Macklis, MD, of Harvard University and the Harvard Stem Cell Institute, an expert on development and regeneration of the mammalian central nervous system. "Solid, rigorous, and well-defined pre-clinical work in animals can set the stage toward human clinical trials and effective future therapies."

Protein could be key for drugs that promote bone growth

AppId is over the quota
AppId is over the quota
corner top left block corner top right October 16, 2012

AUGUSTA, Ga. - Georgia Health Sciences University researchers have developed a mouse that errs on the side of making bone rather than fat, which could eventually lead to better drugs to treat inflammatory diseases such as rheumatoid arthritis.

Drugs commonly used to treat those types of conditions - called glucocorticoids - work by turning down the body's anti-inflammatory response, but simultaneously turn on other pathways that lead to bone loss. The result can lead to osteoporosis and an accumulation of marrow fat, says Dr. Xingming Shi, bone biologist at the GHSU Institute of Molecular Medicine and Genetics.

The key to the body developing bone instead of fat, a small protein called GILZ, was shown in cell cultures in 2008. Now, with work by GHSU Graduate Student Guodong Pan, the work has been replicated in an animal model. Pan received the American Society for Bone and Mineral Research's Young Investigator Award for his work at the society's annual meeting Oct. 12-15 in Minneapolis.

Bone and marrow fat come from the same biological precursor - mesynchymal stem cells. "The pathways for bone and fat have a reciprocal relationship, so we needed to find the key that disrupts the fat production pathway, which would then instead encourage bone growth," Shi says.

GILZ, Shi and Pan say, was already a known mediator of the anti-inflammatory response of glucocorticoids, and the protein also mediates bone production. Shi's early research had shown that glucocorticoids enhance bone formation in the lab because of a short "burst" of GILZ.

The protein works by inhibiting the way cells regulate fat production and turn on fat-producing genes, Shi says. "When you permanently express GILZ, the fat pathway is suppressed, so the body chooses to produce bone instead."

"We found that when we overexpressed the protein in these mice, it increased bone formation," Pan added. "This supports our original hypothesis that GILZ mediates the body's response to glucocorticoids and encourages bone growth." In fact, the genetically modified mice showed a significant increase in bone mineral density and bone volume as well, he found.

"That means GILZ is a potential new anti-inflammatory drug candidate that could spare people from the harmful effects associated with glucocorticoid therapy," Pan said

Long-term goals, Shi said, are developing the GILZ-like pill that is anti-inflammatory and protects or even increases bone production.

Evidence on Ergogenic Action of Glucocorticoids as a Doping Agent Risk (The Physician and Sportsmedicine) Evidence on Ergogenic Action of Glucocorticoids as a Doping Agent Risk (The Physician and Sportsmedicine)
by JTE Multimedia

Systemic administration of glucocorticoids (GCs) is banned by the World Anti-Doping Agency (WADA) during competition. Few studies have examined the effects of GCs on exercise performance, but increasing evidence has shown that short-term GC intake enhances performance in animals and humans. However, there are many health risks associated with GC use. Based on the available evidence, as presented in this article, I conclude that GCs are doping agents and should remain on the WADA’s list of banned products. Because of the complexity of GCs, however, determining the boundaries between their medical use and abuse (eg, in sports) is a constant challenge for the WADA.

The long-term use of glucocorticoids is associated with several deleterious effects. Attempts to separate the beneficial from the adverse effects of these compounds have met with varying degrees of difficulty. The discovery of distinct modes of action of the glucocorticoid receptor, the protein that mediates glucocorticoid action has opened up many possibilities for improving glucocorticoid therapy. This book provides an in-depth overview of the molecular actions of the glucocorticoid receptor and discusses the chances of an imminent identification of selective glucocorticoid agonists. Such componds should fulfill all the criteria of a glucocorticoid but should lack the sideeffects so far linked with classical glucocorticoids.
