    It’s time for scientists and bioethicists to establish a Embryonic Stem Cell Truth and Reconciliation Commission.It all seems so long ago now. But from 2002 to 2008 they barnstormed, fibbed, exaggerated, hyped, and caricatured to get government funding so that they could play God with human embryos. It was a brutal battle in which truth came second. "People need a fairy tale," said Ronald D.G. McKay, a leading stem cell scientist, in 2004.The claims made for the near-miraculous potential of human embryonic stem cells were extraordinary. Celebrities and scientists spoke with the breathless enthusiasm normally associated with crystal medicine or ayurvedic...

    The London Daily Express ^ | September 29, 2015 | David Pilditch
    A BRITISH pensioner has become the first person to undergo revolutionary eye surgery aimed at curing blindness in millions of people. The 60-year-old woman, who had severely impaired sight and was in danger of going blind, is said to have had no complications so far following the three-hour operation last month. The surgical team hopes to determine how successful the treatment was by early December. The woman has asked to remain anonymous. The scientists behind the pioneering procedure hope it will dramatically transform lives, allowing the blind to recognise faces of loved ones again and regain the ability to carry...

    Fears are growing over the side effects of cholesterol-lowering pillsScientists have found the heart disease drug badly affects our stem cells, the internal medical system which repairs damage to our bodies and protects us from muscle and joint pain as well as memory loss. Last night experts warned patients to “think very carefully” before taking statins as a preventative medicine. A GP expert in the field said: “They just make many patients feel years older. Side effects mimic the ageing process.” The new research by scientists at Tulane University in New Orleans has reignited the debate about statin side effects which many doctors...

    September 23, 2015 (LifeSiteNews) Retired hockey star Gordie Howe and NFL football star John Brodie have both had fetal stem cells injected into their spines to treat strokes, but because they had adult stem cells administered intravenously at the same time, critics say there is no way to know if their recoveries derive from the fetal cells. "There is no way to learn which is responsible," Theresa Deisher of Seattle-based AVM Biotechnology, told LifeSiteNews. A second problem is more serious: fetal stem cells were the scientific rage a decade ago because of their capacity to turn into any kind...

    The human body is a complex biological system. In order to fully understand this complex system, in vivo (live) analysis is often required. However, the study of human biology in vivo is severely limited due to ethical and technical constraints. In place of human models, humanized mice have been created to fill this role. These humanized mice have become important tools for the in vivo studies of human cells, tissues, and organs, without putting individuals at risk. Such humanized mouse models may be used to model the human immune system in scenarios of health and pathology. A successful means of...

    Abstract Here, we propose a new strategy for the treatment of early cancerous lesions and advanced metastatic disease, via the selective targeting of cancer stem cells (CSCs), a.k.a., tumor-initiating cells (TICs). We searched for a global phenotypic characteristic that was highly conserved among cancer stem cells, across multiple tumor types, to provide a mutation-independent approach to cancer therapy. This would allow us to target cancer stem cells, effectively treating cancer as a single disease of stemness, independently of the tumor tissue type. Using this approach, we identified a conserved phenotypic weak point a strict dependence on mitochondrial biogenesis for...

    The pitch was intriguing: U.S. health officials wanted to fast-track trials for an Ebola vaccine and sounded the call for volunteers. Charles Sullivan called up the hotline on a whim, figuring the National Institutes of Health already had filled its queue and wouldnt need him. But he was accepted for three rounds of shots of a deactivated virus, a years worth of blood analysis and a $900 check for his trouble. The clinical trial went well, and the vaccine seemed promising. A decade later, the country is still waiting for a vaccine amid a worldwide Ebola outbreak, and Mr. Sullivan...

Marban led one of the earlier stem cell trials, using cells taken by biopsy from the patient's own heart. The cells were multiplied in a laboratory for two to three weeks and then reinfused through a catheter. At the time, says Marban, it was thought that the stem cells themselves turned into new heart muscle and blood vessels. "In fact, the more we learned, the more we realized that that's not what these cells...

    Fasting for as little as three days can regenerate the entire immune system, even in the elderly, scientists have found in a breakthrough described as remarkable. Although fasting diets have been criticized by nutritionists for being unhealthy, new research suggests starving the body kick-starts stem cells into producing new white blood cells, which fight off infection. Scientists at the University of Southern California say the discovery could be particularly beneficial for people suffering from damaged immune systems, such as cancer patients on chemotherapy. [] Scientists found that prolonged fasting also reduced the enzyme PKA, which is linked to aging and...

    Scientists are reporting a significant milestone for cancer research after charting 21 major mutations behind the vast majority of tumours. The disruptive changes to the genetic code, reported in Nature, accounted for 97% of the 30 most common cancers. Finding out what causes the mutations could lead to new treatments. Some causes, such as smoking are known, but more than half are still a mystery. Cancer Research UK said it was a fascinating and important study. A tumour starts when one of the building blocks of bodies, a cell, goes wrong. Over the course of a lifetime cells pick up...

    A decade ago, gene expression seemed so straightforward: genes were either switched on or off. Not both. Then in 2006, a blockbuster finding reported that developmentally regulated genes in mouse embryonic stem cells can have marks associated with both active and repressed genes, and that such genes, which were referred to as "bivalently marked genes", can be committed to one way or another during development and differentiation. This paradoxical stateakin to figuring out how to navigate a red and green traffic signalhas since undergone scrutiny by labs worldwide. What has been postulated is that the control regions (or promoters) of...

    Francois Lenoir/Reuters Meet the new meat. Tiny pieces of muscle tissue grown in the lab will make up the patty of the first test-tube burger to be unveiled in London on Monday. If you take some scientists' word for it, the biggest agricultural revolution since the domestication of livestock is starting on Mondayin an arts center in London. At a carefully orchestrated media event, Dutch stem cell researcher Mark Post is planning to present the world's first test-tube hamburger. Its patty is made from meat that Post has laboriously grown from bovine stem cells in his lab at an estimated...

    Could harvesting stem cells for therapy one day be as simple as asking patients for a urine sample? Researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine and colleagues have identified stem cells in urine that can be directed to become multiple cell types. "These cells can be obtained through a simple, non-invasive low-cost approach that avoids surgical procedures," said Yuanyuan Zhang, M.D., Ph.D., assistant professor of regenerative medicine and senior researcher on the project. Reporting online in the journal Stem Cells, the team successfully directed stem cells from urine to become bladder-type cells, such as smooth muscle...

    Scientists have grown rudimentary teeth out of the most unlikely of sources, human urine. The results, published in Cell Regeneration Journal, showed that urine could be used as a source of stem cells that in turn could be grown into tiny tooth-like structures. The team from China hopes the technique could be developed into a way of replacing lost teeth. Other stem cell researchers caution that that goal faces many challenges. Teams of researchers around the world are looking for ways of growing new teeth to replace those lost with age and poor dental hygiene. Stem cells - the master...

    A multinational team of scientists led by Prof Benjamin Blencowe from the University of Toronto has identified proteins that play a key role in controlling pluripotency, which may mean a potential breakthrough in producing the so-called induced pluripotent stem cells.Colonies of the induced pluripotent stem cells (Boston University Center for Regenerative Medicine) Induced pluripotent stem cells can be of great value for medical research because they can flexibly develop into many different types of cells. However, producing these cells is challenging because the proteins that control their generation are largely unknown.The team discovered the proteins using the splicing code developed...

    A significant percentage of America’s 45.6 million dog owners and 38.2 million cat owners have first-hand familiarity with state-of-the-art medical facilities for pets that rival the most sophisticated human hospitals: animal emergency centers where veterinary specialists — including neurologists, orthopedists, oncologists, and criticalists — prolong the lives of pets whose owners can afford the service. The mainstream media rarely misses a chance to point out that animal medical care in the United States is almost on par with the best in human health care. But the reality is that the level of animal medical innovation has actually surpassed that of...

    Initiative aims to clarify description of mesenchymal cells. Pamela Robey is used to being sent samples by scientists who are anxious to know whether the mesenchymal stem cells (MSCs) they have extracted from fat can be coaxed to turn into either bone or cartilage. Robey, who directs the Stem Cell Unit at the US National Institutes of Health (NIH), is also used to delivering bad news to many of those who seek her help. They usually are not happy, she says, when her attempts to differentiate the cells produce little more than fatty globules. To Robey, that disappointment reflects a...

    Georgia Tech/Emory University Associate Professor Todd McDevitt and graduate student Anh Nguyen make microparticles to be used for delivering growth factors to stem cells. Credit: Rob Felt Before scientists and engineers can realize the dream of using stem cells to create replacements for worn out organs and battle damaged body parts, they'll have to develop ways to grow complex three-dimensional structures in large volumes and at costs that won't bankrupt health care systems. Researchers are now reporting advances in these areas by using gelatin-based microparticles to deliver growth factors to specific areas of embryoid bodies, aggregates of differentiating stem...
