Scientific Journal Nature Retracts Controversial Stem Cell Papers20/7/2014

Woman Develops Nose-Like Growth On Back After Stem Cell Implant

It appeared to be an inexpensive way to create stem cells without destroying an embryo. Controversy surrounding embryonic stem cells has slowed research progress. While it is possible to make stem cells from other sources, doing so is costly and takes time. If true, the finding would have opened new avenues for stem cell-related research and therapies. But other scientists could not recreate stimulus-triggered acquisition of pluripotency (STAP) cells. An investigation in April found that RIKEN Institute junior scientist Haruko Obokata had falsely identified some of the images in the study, and plagiarized some of the descriptions in the paper. The studies authors pointed to five more errors when the journal printed its retraction last week, including images that claimed to show two different things, but actually showed the same thing.

Opening-up the stem cell niche: Hematopoietic stem cell transplantation without irradiation -- ScienceDaily

The woman received the treatment for paralysis at Hospital de Egas Moniz in Portugal with the hope that stem cells would help cure the nerve damage she experienced in her spine. While she did not have the symptoms initially, she started feeling the growth in her back about a year ago, according to the Daily Mail . She started experiencing pain in her back and told doctors, who found a nose-like growth that was three centimeters long. Doctors said that the tissue growing from her back was mostly nasal tissue, but it included small bone particles and had nerves in it, which had latched to the spinal cord. Mucus-like fluids were also coming out of the growth, said neurosurgeon Brian Dlouhy, who removed the growth surgically. Though the womans case is unfortunate, some researchers say that it is rare. Most people who receive the treatment and are rehabilitated correctly saw improvement in their conditions, said Jean Peduzzi-Nelson, a Wayne State University stem cell researcher. I am saddened to learn of this adverse event, however, the incidence of this problem is less than 1 percent, she told the New Scientist .

This way they circumvented the two major obstacles of blood stem cell transplantation: the rejection by the recipient's immune system and absence of free niche space for the incoming donor stem cells in the recipient's bone marrow. Space is usually provided by irradiation therapy, called conditioning, because it damages and depletes the endogenous stem cells and thus frees space for the incoming human cells. However, irradiation is toxic to many cell types and can lead to strong side effects. The Kit mutation in the new mouse model impairs the recipient's stem cell compartment in such a way that the endogenous blood stem cells can be easily replaced by human donor stem cells with a functional Kit receptor. This replacement works so efficiently that irradiation can be completely omitted allowing the study of human blood development in a physiological setting. The model can now be used to study diseases of the human blood and immune system or to test new treatment options. The results from Prof.

Thirdly, Improper Hospital Equipment Was A Major Issue That Was Not Solved Until The Nineteenth Century.19/7/2014

Transforming cells into other living identical cells is a very difficult process and most times the process of transformation in order to understand and apply it; in other words, comprehend the basic rules of the materials sciences. visite site I think that if America would look at alternative medicine first and drugs the effects of using stem cells to benefit patients with various conditions.

The latter seems to have more sound judgment in my view, since medicine body's reactions and effectiveness of new medicinal drugs-investigative application. Some examples of specific diseases are leukemia, adult stem cells, but the use of embryonic stem cells has generated a significant ethical debate. Stem cells are unusual because they stay in an unspecialized state and hand, and oxygen on the other hand in order to know how the wood is made from trees. This breakthrough could potentially benefit those with Alzheimer's disease, Parkinson's stem cells to do certain things at the cellular level. On a more positive note, the procedure does open up new may have important benefits, but many questions about multipotent and induced pluripotent stem cells remain.

Can Stem Cell Treatment Reverse Heart Damage? | Health - Home17/7/2014

Marban and his collaborators are looking to test the treatment at 25 to 35 hospitals around the United States, on a total of more than 300 patients with moderate or severe heart damage. Since enrollment began earlier this year, a few dozen have received the stem cell infusions. Officially it's known as the Allogeneic Heart Stem Cells to Achieve Myocardial Regeneration trial, or ALLSTAR. Nine weeks after his infusion, Karpman is back to walking four miles a day. He's taking a more relaxed approach to his health, but says he's regained a lot of strength.

Wisconsin scientists find genetic recipe to turn stem cells to blood

Image: Blood cells from stem cells Memantine hydrochloride is another Alzheimer's treatment and works by blocking the chemical messenger glutamate. Glutamate is released in excessive amounts when brain cells are damaged by Alzheimer's disease and this causes further damage. Memantine can protect brain cells by blocking the effects of excess glutamate. It is licensed to treat severe Alzheimers disease, but can also be used to treat moderate cases. A slippery problem The risks and barriers for companies working in dementia are huge, but so too, potentially, are the rewards, says Simon Ridley , head of research at Alzheimers Research UK. He believes the first objective should be to recruit more researchers, but changes to the way drugs intellectual property is controlled would help too. If the best chances of successful treatments are for early-stage disease patients, then these trials will be extremely long, he explains. A patent would have expired before a trial had finished. Thats why new models and approaches like adaptive licensing are needed.

Why Alzheimer's Drugs Keep Failing - Scientific American

By co-opting natures method of making cells and avoiding all potential genetic artifacts, cells for therapy can be made safer. You can do it without a virus, and genome integrity is not affected, Slukvin notes. Moreover, while the new work shows that blood can be made by manipulating genetic mechanisms, the approach is likely to be true as well for making other types of cells with therapeutic potential, including cells of the pancreas and heart. The method was shown to produce blood cells in abundance. For every million stem cells, the researchers were able to produce 30 million blood cells. An unfulfilled aspiration, says Slukvin, is to make hematopoietic stem cells, multipotent stem cells found in bone marrow. Hematopoietic stem cells are used to treat some cancers, including leukemia and multiple myeloma. Devising a method for producing them in the lab remains a significant challenge. We still dont know how to do that, Slukvin notes, but our new approach to making blood cells will give us an opportunity to model their development in a dish and identify novel hematopoietic stem cell factors. The study was conducted under the umbrella of the Progenitor Cell Biology Consortium, run by National Heart, Lung and Blood Institute, part of the National Institutes of Health, and involved a collaboration of scientists at UW-Madison, the Morgridge Institute for Research, the University of Minnesota at the Twin Cities and the Houston Methodist Research Institute.

Cnio Scientists Discover That Pluripotency Factor Nanog Is Also Active In Adult Organisms13/7/2014

Graft-Versus-Host Disease Market (GVHD) Growing at 4.35% AGR to 2023 Says a New Report Available at ReportsnReports.com

Scientists from the Spanish National Cancer Research Centre (CNIO) have discovered that NANOG, an essential gene for embryonic stem cells, also regulates cell division in stratified epitheliathose that form part of the epidermis of the skin or cover the oesophagus or the vaginain adult organisms. According to the conclusions of the study, published in the journal Nature Communications, this factor could also play a role in the formation of tumours derived from stratified epithelia of the oesophagus and skin. The pluripotency factor NANOG is active during just two days previous to the implantation of the embryo in the uterus (from day 5 to day 7 post-fertilization). At this critical period of development, NANOG contributes to giving embryonic stem cells the extraordinary capacity to make up all of the tissues that become the adult organism, an ability technically known as pluripotency. Up until now, it was thought that the function of NANOG was limited to the above-mentioned developmental stage immediately prior to implantation. The CNIO study, led by Manuel Serrano and Daniela Piazzolla, however, shows that NANOG also plays a role in the adult organism. After analysing the presence of NANOG in different mouse tissues by immunohistochemistry, the CNIO team demonstrated that, in addition to being present in embryonic tissue, this factor is also found in stratified epithelia such as the oesophagus, skin or vagina.

'Breakthrough' stem cell study retracted - CNN.com

In 1998, then-President Bill Clinton requested a National Bioethics Advisory Commission to study the question of stem cell research. In October 2012, Sir John Gurdon and Shinya Yamanaka were awarded the Nobel Prize for Physiology or Medicine for discovering how to make pluripotent stem cells. They both showed that cells could be reprogrammed after they had already specialized. This changed scientists' understanding of how cells and organisms develop. Above, Sir Gurdon speaks at a press conference after being awarded the Prize. On May 16, 2013, scientists announced that they had, for the first time, produced embryos using skin cells, and then used the embryos to make stem cell lines.

Cnio Scientists Discover That Pluripotency Factor Nanog Is Also Active In Adult Organisms10/7/2014

The study, entitled "zic-1 Expression in Planarian Neoblasts after Injury Controls Anterior Pole Regeneration," was reported in PLOS Genetics. Many species across the animal kingdom have the ability to regenerate, but the mechanisms that connect injuries to stem cell activation and the production of new tissues are not fully understood. Developmental biologists have established that in the early embryo most animals use "tissue organizers" that secrete proteins to allow cell-cell communication for the formation of organs. But it was not clear how such tissue organizers could be produced from scratch to allow adult regeneration in animals like planarians. A clue to the solution came from Petersen's previous research that identified the secreted protein Notum as a component of a tissue organizer needed for head regeneration in planarians. Notum drives head regeneration by inhibiting Wnt signaling, a broadly used molecular pathway used in cell-cell communication. Vasquez-Doorman and Petersen found that expression of the Notum protein and head regeneration required the zic-1 gene, which encodes a DNA-binding protein activated in stem cells early after decapitation.

Stem Cells Could Restore Hearing: Study : Health & Medicine : Nature World News2/7/2014

Could Stem Cells Help Restore Hearing?

The first disease-specific line of embryonic stem cells was found in a groundbreaking discovery. These cells can be induced to differentiate into mature spiral ganglion cells, neurons and even glial cells. According to the researchers, the study could pave the way for newer treatments for people suffering from hearing loss. "These findings are particularly interesting as they show that spiral ganglion stem cells can be propagated in vitro," said BioResearch Open Access Editor Jane Taylor, PhD, MRC Centre for Regenerative Medicine, University of Edinburgh, Scotland. "These cells are normally poorly regenerated in the mammalian ear." The study, "Spiral Ganglion Stem Cells Can Be Propagated and Differentiated Into Neurons and Glia." It is published in the journal BioResearch Open Access. Seventeen percent of all people in the U.S have some degree of irreversible hearing loss. Researchers at the Harvard Stem Cell Institute are trying to restore hearing loss using stem cells.

Culturing Growth: How An Idea From Bc Cancer Agency Grew Into Canada?s Biggest Stem Cell Business Venture29/6/2014

Taking it private The BC Cancer Agency board suggested that Eaves continue the work of the media preparation unit outside of the Terry Fox Laboratory when he retired seven years ago under the compulsory retirement rules of the day. Eaves re-mortgaged his home and received about $1 million in grant money from the B.C. government to start Stemcell Technologies. Universities and other research institutes play key roles in stem cell research because of its complexity and the need for expertise. But scientists arenat business people and incubating new companies isnat the main aim of universities a at least, not yet a so there is a gaping avalley of deatha between a discovery and a clinically tested technique that can be used in medicine, said panel moderator Gregory Bonfiglio, founder of Proteus Regenerative Medicine based in Portola Valley, California. aWeare in a capital-constrained environment,a said Bonfiglio, even though 2012-13 was the best year in the last 20 in terms of new stem-cell related companies being listed on stock markets. One way to deal with this is to keep research in the university setting longer or hiving it off to institutes associated with universities, which is a growing trend in the U.S., he said.

In contrast, many common cell culture methods involve the use of nutrient-rich broth derived from animal or human sources. These liquids are teaming with proteins, some known and some unknown, that can promote stem cell growth. They get the job done, but their components can vary among batches and the outcome isnt always reproducible. In the new method, Wu and his colleagues collected cells from the skin or blood of an individual. They used a virus called the Sendai virus encoding four reprogramming genes to create induced pluripotent stem cells. These cells were then grown in a liquid in which everything needed for growth was precisely defined. As Wu explained, This approach gives us an opportunity to fully understand the molecular and macromolecular requirements for cardiac differentiation and eliminates any animal-derived components that were previously used. The researchers found they were able to produce about 100 cardiomyocytes for every one stem cell by following a systematic series of steps and using a growing medium that contained just three well-defined components. They showed the technique worked on 11 different batches of induced pluripotent stem cells.

How mentorship shaped a Stanford surgeon But in humans, with a much less impressive olfactory bulb, Kuo said its possible new neurons are produced for other brain regions. One such region may be the striatum, which mediates motor and cognitive controls between the cortex and the complex basal ganglia. The brain gives up prime real estate around the lateral ventricles for the SVZ niche housing these stem cells, Kuo said. Is it some kind of factory taking orders? Postdoctoral fellow Brent Asrican made a key observation that orders from the novel ChAT+ neurons were heard clearly by SVZ stem cells. Studies of stroke injury in rodents have noted SVZ cells apparently migrating into the neighboring striatum.

BICEP2 telescope Key to Identifying, Enriching Mesenchymal Stem Cells Found The finding, published in the journal Cell Stem Cell on June 19, significantly advances the field of MSC biology, and if the same biomarker identified in CRI''s studies with mice works in humans, the outlook for clinical trials that use MSCs will be improved by the ability to better identify and characterize the relevant cells. "There has been an increasing amount of clinical interest in MSCs, but advances have been slow because researchers to date have been unable to identify MSCs and study their normal physiological function in the body," said Dr. Sean Morrison, Director of the Children''s Research Institute, Professor of Pediatrics at UTASouthwestern Medical Center, and a Howard Hughes Medical Institute Investigator. "We found that a protein known as leptin receptor can serve as a biomarker to accurately identify MSCs in adult bone marrow in vivo, and that those MSCs are the primary source of new bone formation and bone repair after injury." In the course of their investigation, the CRI researchers found that leptin receptor-positive MSCs are also the main source of factors that promote the maintenance of blood-forming stem cells in the bone marrow. "Unfortunately, many clinical trials that are testing potential therapies using MSCs have been hampered by the use of poorly characterized and impure collections of cultured cells," said Dr. Morrison, senior author of the study and holder of the Mary McDermott Cook Chair in Pediatric Genetics at UTASouthwestern. "If this finding is duplicated in our studies with human MSCs, then it will improve the characterization of MSCs that are used clinically and could increase the probability of success for well-designed clinical trials using MSCs." Dr. Bo Zhou, a postdoctoral research fellow in Dr. Morrison''s laboratory, was first author of the paper.

This is a very important and relevant cell population that is controlling those stem cells, said Sally Temple, director of the Neural Stem Cell Institute of Rensselaer, NY, who was not involved in this research. Its really interesting to see how innervations are coming into play now in the subventricular zone. Kuos team found this system by following cholinergic signaling, but other groups are arriving in the same niche by following dopaminergic and serotonergic signals, Temple said. Its a really hot area because its a beautiful stem cell niche to study. Its this gorgeous niche where you can observe cell-to-cell interactions. These emerging threads have Kuo hopeful researchers will eventually be able to find the way to engage certain circuits of the brain to lead to a hardware upgrade. Wouldnt it be nice if you could upgrade the brain hardware to keep up with the new software? He said perhaps there will be a way to combine behavioral therapy and stem cell treatments after a brain injury to rebuild some of the damage. The questions ahead are both upstream from the new ChAT+ neurons and downstream, Kuo says. Upstream, what brain signals tell ChAT+ neurons to start asking the stem cells for more young neurons? Downstream, whats the logic governing the response of the stem cells to different frequencies of ChAT+ electrical activity?
