Can Stem Cells Treat Diabetes?
Stem cells are seen as the miracle cure of the future for many degenerative diseases. Scientists and physicians also hope that stem cells will exert their regenerative effect in the treatment of diabetes type 1 which is caused by damaged tissue. Prof. Dr. Jochen Seufert and Dr. Gnter Pth from the University Hospital of Freiburg are investigating whether it is possible to use certain types of stem cells to regenerate the bodys own insulin production. The biological relationships involved have proved to be very complex. The two specialists are quick to point out that an early cure is not likely. However, they are cautiously optimistic about the far-reaching potential of stem cells. Diabetes type 1 is an autoimmune disease. In diabetes patients, the bodys defence system has an allergic reaction to the -cells in the pancreas. The immune cells attack and destroy the -cells. The body is no longer able to produce insulin, which is needed to break down sugar. Diabetes sufferers depend on artificial insulin that they normally have to inject. Although this type of therapy saves many lives, it is nevertheless not an optimal solution as insulin is unable to precisely regulate the blood sugar level. This often leads to blood sugar values that are too high or too low, which in turn drastically reduces sufferers quality of life and also leads to diabetic complications later on. The transplantation of insulin-producing cells might offer a better possibility of treating the disease, said Prof. Dr. Jochen Seufert, head of Endocrinology and Diabetology in the Department of Internal Medicine II at the University Medical Centre Freiburg. But this type of treatment also has its disadvantages. Nowadays, physicians either transplant a whole pancreas or just the part that contains the -cells, Continue reading >>
Stories Of Hope: A Stem Cell Therapy For Diabetes
Home Stories of Hope: A Stem Cell Therapy for Diabetes Stories of Hope: A Stem Cell Therapy for Diabetes The last thing Maria Torres expected was to be diagnosed with type 2 diabetes. She exercised, ate well and kept her weight under control. There had to be some mistake. Maria asked her doctor to repeat the tests, but the results were the same. At 43, for reasons no one could fully explain, she had diabetes, and her life was going to change dramatically. It really scared me, says Maria. I thought I was going to die soon. That Maria doubted her diagnosis is no surprise. Type 2 diabetes is often associated with obesity, and she didnt fit the profile. Most likely, some undiscovered genetic component had made her susceptible to the disease. Regardless, she now had to rework her life to manage the diabetes. Her cells had developed a condition called insulin resistance. Though her pancreas was producing insulin, which tells cells to take in blood sugar, the cells were not cooperating. As a result, glucose was accumulating in her blood, putting her at risk for heart disease, nerve damage, eye issues and a host of other problems. To help her cells absorb glucose, she needs regular insulin injections. Maria injects the hormone five times a day and must often measure her blood sugar levels even more frequently. Faithfully following this regimen has kept her alive for 20 years, but insulin is not a cure. Even with the regular injections, she faces dramatic mood swings and more serious complications as glucose levels rise and fall. One of the most promising strategies to cure diabetes is to transplant beta cells, which sense blood sugar levels and produce insulin to reduce them. Patients with type 1 diabetes would benefit because new beta cells would replace the ones theyd lost t Continue reading >>
Diabetes | Canadian Stem Cell Foundation
Are there stem cell therapies available for type 1 diabetes? To our knowledge, no stem cell therapy has received Health Canada or U.S. Food and Drug Administration approval for treatment of type 1 diabetes at this time. Patients who are researching their options may come across companies with Web sites or materials that say otherwise and offer fee-based stem cell treatments for curing this disease. Many of these claims are not supported by sound scientific evidence and patients considering these therapies are encouraged to review some of the links below before making crucial decisions about their treatment plan. For the latest developments read our blog entries here . More about stem cell clinical trials for diabetesclick here . (For printed version: How close are we? What do we know about type 1 diabetes? The insulin-producing beta cells of the pancreas are attacked and destroyed by the bodys immune system cells. A persons environment, genetics and the infections they are exposed to over their lifetime all play a role in triggering the attack on beta cells. When the beta cells are destroyed, the production of insulin drops and our cells can no longer take in the sugar glucose. When glucose is left circulating in the blood at very high levels the blood vessels, eyes, kidneys, nerves and heart can be damaged. If type 1 diabetes is not diagnosed and treated in time with injections of insulin, a patient could fall into a life-threatening coma. Just a few teaspoonfuls of pancreatic islet cells can temporarily reverse type 1 diabetes. There is a shortage of donor pancreatic islet cells for treating patients with type 1 diabetes. Type 1 diabetes is an ideal candidate for a stem cell therapy because the disease can be traced to the loss of a single cell type the beta cell. St Continue reading >>

Diabetes And Stem Cell Research
Stem cell research is in progress for the treatment of diabetes Understanding the root causes of diabetes has eluded researchers for many years now. The way in which the immune system causes the destruction of precious beta islet cells within the pancreas of type 1 diabetics is generally understood to be the key. The ultimate goal, which has so far proved elusive, is a cure for diabetes , which could potentially be available for both types of diabetes through stem cell research. Stem cells are a form of cell that is yet to develop a specific set of traits. However, what stem cells have in abundance is the potential to develop into a number of different forms. Stem cell research covers the scientific study of these stem cells. Stem cell research allows researchers to grow specific varieties of human cells in the lab and research how they behave and interact under different conditions. Stem cells open up a wide spectrum of diabetes research possibilities. In one example of diabetes stem cell research, researchers took cells from human intestine cells and disabled a gene which enabled the cells to produce insulin. Stem cells for the treatment of diabetes are able to come from a variety of sources. Stem cells in the research of type 1 diabetes Within recent years, stem cell research has become a very important part of the scientific understanding of type 1 diabetes. Research has demonstrated that stem cells can be grown in the lab. In 2004, the University of Pittsburgh grew insulin producing beta cells by introducing two genes cdk and cyclin d via a virus. The researchers were able to deactivate the virus and also prevent stem cells from growing further. The research could lead to a better availability of beta cells for future research purposes.

Enhanced Stem Cells For Treating Diabetes Mellitus Type 1 & 2
Updated November 22, 2017 – In the unfortunate event you or perhaps a family member are coping with diabetes you should be aware of its consequences on the body and mind. Diabetes is usually termed the “silent killer” mainly because it strikes the body slowly and without warning. Newly diagnosed diabetic patients are usually not worried about it since their symptoms are often no more severe than recurrent urination and increased thirst. A number of other individuals have no symptoms at all. Treating Diabetics With Stem Cells As time goes by however, the effects of both kinds of diabetes become increasingly serious and may lead to death. These symptoms include heart disease, eye issues, kidney failure, nerve damage and erectile dysfunction, to name a few. Hypoglycemia (acute low blood sugar) and hyperglycemia (high level of blood sugar) are the key contributors to the effects of diabetes. According to recent research, some of the oral diabetes medications can also help contribute to heart malfunction.(Kao and Chen 2012)* That is exactly why it’s important that women and men who are clinically diagnosed as “diabetic” immediately seek treatment to relieve hypoglycemia and hyperglycemia. These conditions often trigger the more harmful, degenerative ailments. The regeneration center can help treat DM with our innovative enriched and expanded Mesenchymal cells treatment for Diabetes safely and without any artificial medicines or need for regular insulin dependency.(Yong Zhao et al. 2013)* Reverse Hyperglycemia with Insulin Producing Beta-Cells Stem Cell treatments for diabetes fights the disease at its origins in the pancreas. Decreasing hyperglycemia as well as associated complications (see above). According to recent research, it can also relieve hypoglycemia or Continue reading >>
Researchers Working With Stem Cells To Treatdiabetes
AURORA, Colo (CBS4) Stem cells could be the key to curing Type 1 diabetes. Researchers at the Barbara Davis Center for Diabetes are working on ways to give diabetic patients new insulin-producing cells. David Ramirez is a researcher at the Barbara Davis Center , hes also a Type 1 diabetic. Diagnosed 21 years ago, Ramirez checks his blood sugar regularly. He watches what he eats and balances his exercise. I definitely worry about it, he told CBS4. He thinks about Type 1 diabetes every hour of every day. Things arent perfect. I still dont know how to bolus for pizza correctly, he said with a laugh. Ramirez looks forward to a day when he doesnt have to calculate the carbs in a slice of pizza. Holger Russ, an assistant professor at the Barbara Davis Center , works toward that day too. We definitely have a cure in mind, Russ told CBS4. Holger Russ of the Barbara Davis Center for Diabetes (credit CBS) Russ works with pluripotent stem cells. Every day, he and his team feeds them and grows them. Three years ago, he was able to coax the stem cells into becoming glucose-reactive, insulin-producing beta cells. They can function there, can basically secrete insulin in response to an increase in blood sugar, which happens after the patient ate, Russ explained. Beta cells are the very cells that Ramirez is missing, which requires him to pump insulin into his body. We made a big step, and there are about 2 more big steps to take, Russ said. Those steps include figuring out how to protect the new insulin cells as they go into and live in a patients pancreas. If we can replace their beta cells, we would now have a biological pancreas, not an artificial pancreas, said Lori Sussel, research director at the Barbara Davis Center . Essentially a cure, but a cure for Type 1 diabetes comes at Continue reading >>
Diabetes Type 2 - Stem Cells Treatment Clinic
Diabetes Type 2 Stem Cell Treatment Diabetes type 2 is a metabolic disorder that is characterized by high blood sugar and lack of insulin, a hormone produced in the pancreas that regulates the metabolism of carbohydrates. It is typically a chronic disease with a ten-year shortened life expectancy and symptoms such as: increased thirst, frequent urination, and constant hunger. There are a number of associated complications including: two to four times the risk of a cardiovascular disease and stroke, a 20-fold increase in lower limb amputations, and increased hospitalizations. Type 2 diabetes is the largest cause of non-traumatic blindness and kidney failure. It is associated with an increased risk of cognitive dysfunction and dementia, such as Alzheimer's disease. Other complications include: sexual dysfunction and frequent infections. Causes of type 2 diabetes: - obesity - poor diet - low activity level - genetics and family history Other diabetes risk factors include old age, high blood pressure, history of gestational diabetes, polycystic ovarian syndrome, impaired glucose intolerance and ethnicity, as African Americans, Hispanic Americans, and Native Americans are prone to an increased incidence of diabetes because of a history of gestational diabetes. With Type 2 Diabetes the body becomes insensitive and less able to produce insulin, which transports glucose from the bloodstream into body tissues. Instead the sugar volume in the blood builds up. The pancreas may increase insulin production but it does not rectify the problem. Other symptoms of this disease include blurred vision, fatigue, increased appetite, thirst and urination, slow-healing or frequent infections and erectile dysfunction. In both forms of diabetes, unless treated, blood sugar will rise uncontrolla Continue reading >>
Diabetes | Harvard Stem Cell Institute (hsci)
HOME / RESEARCH / DISEASE PROGRAMS / DIABETES PROGRAM / It stands to reason that only by understanding the root causes of diseases like diabetes can we hope to develop effective therapies. Modern biomedical research is best at finding treatments for diseases that have relatively simple causes and well-understood genetic risk factors. Unfortunately, type 1 diabetes (T1D) has very complex genetics, with many genes each making relatively small, poorly understood contributions to disease risk. Further, there are no animal models that accurately reflect the human disease. Thus, despite the expenditure of hundreds of millions of research dollars, no cures for T1D have been developed. T1D is particularly challenging to study in human patients. By the time a patient is diagnosed with T1D, also known as juvenile diabetes, the destruction of insulin-producing beta cells by the immune system is nearly complete. Because of this, there is no way to discover what it was that led the persons immune system to attack the beta cells in the first place. Even if it were possible to identify future T1D patients before the immune attack on beta cells began, disease onset and progression could not be studied in these individuals due to the inaccessibility of the pancreas where beta cells are found in a living person. Harvard Stem Cell Institute (HSCI) scientists are attempting an ambitious, long-term, and high-risk project to create the first animal model for T1D. Engineered mice will allow researchers to better understand the disease and increase the odds of developing effective therapies. Recent advances in stem cell biology have opened the door to new ways of studying T1D. Specifically, it is now possible to reprogram a skin cell from a T1D patient (or any other person) into a cell that c Continue reading >>
Can Stem Cells Help Diabetes?
Stem cell research was big news back when Christopher Reeve, the actor who played Superman in the 1970s and 1980s, became famous again in the 2000s for trying to get laws changed so that research with human embryonic stem cells could expand. After breaking his neck in a horse-riding accident, he used his fame to become an advocate for stem cell research funding. The big problem with this kind of research was that it typically required human embryos that had been donated to science after fertilization therapy for women who were trying to get pregnant. Because of the deep moral issue, I wanted to understand more. For one thing, what on earth was a stem cell? Why were scientists all over the world studying them with such excitement? Every cell in your body is programmed by the genes inside it to do a specific thing. Muscle cells cannot do what blood cells do. Blood cells cannot do what nerve cells do. But every living creature that grows from an egg begins as an embryo made up of a few cells. Every one of those cells has the ability to become whatever the creature will need. When these cells were discovered, they were christened stem cells because of this incredible power. Scientists looked at the stem cells in a mouse embryo and saw a future where they could grow new hearts and repair nerve damage so that people like Christopher Reeve could walk again. A new branch of medical science was born. However, the discovery of these cells brought with it more questions than answers. How did a stem cell learn what it would turn into? What turned the genetic code on and off? Could stem cells be safely grown in the laboratory? If researchers could figure out how to control stem cells, they could use them to make tissues, even replace organs and repair damaged nerves. But that kind Continue reading >>
Nearly 400 million people worldwide are living with diabetes, and that number is expected to jump to almost 600 million by 2035, according to the International Diabetes Federation. For many people, diabetes can be controlled with diet, exercise and, often, insulin or other drugs. However, complications from diabetes can be serious and include kidney failure, nerve damage, vision loss, heart disease and a host of other health issues. In this section: What is diabetes? How is diabetes treated? How are we using stem cells to understand diabetes? What is the potential for stem cells to treat diabetes? At its most basic, diabetes is a condition in which the body cannot regulate or properly use sugar (called glucose) in the blood. The pancreas, which helps the small intestine digest food, has hundreds of thousands of cell clusters called islets of Langerhans where beta cells live. Beta cells produce insulin, which is released into the bloodstream when blood sugar levels reach a certain threshold. The insulin signals other cells in the body to take up sugar, the primary energy source for all the body’s cells. Type 1, also known as juvenile diabetes. In type 1 diabetes, the body’s immune system attacks the beta cells in the pancreas. When the beta cells are damaged, they don’t produce insulin, or at least not enough insulin. Other cells never get the signal to take up sugar, so they don’t get the energy they need to function properly, and high sugar levels in the blood end up causing damage to the kidneys, eyes, nervous system and other organs. Type 2 diabetes, also called adult-onset diabetes. In type 2 diabetes, cells in the body become resistant to insulin. They don’t respond to the signals insulin sends out, so they don’t take up sugar from the blood. The beta c Continue reading >>
Diabetes: How Could Stem Cells Help?
Diabetes is a common life-long condition and the number of children being diagnosed with type 1 diabetes is increasing. The symptoms can be controlled but there is no cure. For many, diabetes means living with daily insulin injections and the possibility of long-term damage to their health. All the cells in your body need energy. This energy is carried around the body as sugar (glucose) in the blood. There are several types of diabetes. What they all have in common is a problem with regulating normal levels of sugar in the blood. Normally, blood sugar levels are controlled by the release of the hormone insulin. Insulin is made by cells in the pancreas called beta cells that are arranged into clusters together with other pancreas cells. These clusters are called islets of Langerhans. In one human pancreas there are roughly one million islets. Where is the pancreas?: located in the abdomen, next to the small intestine and stomach. The cells in the pancreas that make insulin (beta cells) are highlighted in red in this video by Dror Sever and Anne Grapin-Botton. Continue reading >>
Dri Biohub: Supply
Islet transplantation has clearlyshown the ability to restore natural insulin production and normalize blood sugar levels in people with type 1 diabetes. But, some hurdles remain before this cell replacement therapy can be offered more broadly to those who can benefit. Two notable ones are the complex challengesof the immune system and the shortage of insulin-producing cells available for transplant. Currently, islets used for transplantation come from the pancreases of deceased donors. With organ donation in the United States at critically low levels, there are clearly not enough cellsfor everyone. The DRI is developing several pioneeering strategies to create areliable supplyof insulin-producing cells. Scientists have discovered that different types ofcells within the non-insulin producing portion of the pancreas, which makes up 98 percent of the organ, have the ability to become insulin-producing cells. In particular, they have focused on a unique population of stem cells that remain intact after the autoimmune attack in a large percentage of patients. The DRI's Cell Supply team has been developing methods to stimulate these pancreatic stem cells to turn into insulin-producing cells with very promising results. Using a natrually occurring protein called bone morphogenetic protein 7 (BMP-7), DRI reseachers demonstrated that these stem cells within the non-endocrine tissue can become new islets when cultured in the lab. Their pioneering findings using this FDA-approved molecule were published in the journal Diabetes . In itself, the discovery could potentially open the door to transplanting multiple patients from a single donor pancreas, but the results have other promising implications. After observing that these stem cells remained in the pancreas after the onset of Continue reading >>
Stem Cell Factory Opens Door For Trials Of Personalized Diabetes Treatment
In a step that could lead to a new diabetes treatment, several Boston-area hospitals have teamed up with the Harvard Stem Cell Institute and biotech Semma Therapeutics tomake personalized cell-based therapiesand organize clinical trials. It is one of several initiatives around the country aimed at manufacturing cell-derived treatments, as the hope for such therapiescreates a demand for the productionof the cells. In patients with type 1 diabetes , the immune system attacks the pancreatic cells that produce insulin, called beta cells. Doctors have for years transplanted beta cells from dead donors into patients, but the supplyis insufficient for the millions of people with type 1 diabetes, and patients bodies sometimes reject the donor cells. The new program, officially called the Boston Autologous Islet Replacement Program, could provide enough high-quality beta cells needed to treat patients in upcomingclinical trials. And the cells that will be transplanted into these volunteerswill be derived from their ownblood cells, cutting the risk of rejection. For the first trial, which wont start for at least three years, researchers intend to transplant the cells into people who have had their pancreas removed because of pancreatitis or another condition. If the treatment proves effective and safe, doctors could conduct another study with diabetic patients. Diabetes rose fourfold over last 25 years, WHO says As part of the collaboration, clinicians at Brigham and Womens Hospital and the Joslin Diabetes Center will recruit patients. Experts at the Dana-Farber Cancer Institute will derive the stem cells from the patients own blood cells creating what are called induced pluripotent stem cells and coax them into becoming beta cells. Doctors at the Brigham will then perform the t Continue reading >>
Are Stem Cells The Next Frontier For Diabetes Treatment?
Are Stem Cells the Next Frontier for diabetes treatment? Diabetes is a devastating disease that affects millions of people worldwide. The major forms of the disease are type 1 and type 2 diabetes. In type 1 diabetes, the body's immune system aberrantly destroys the insulin-producing beta cells (b-cells) of the pancreas. Type 2 diabetes, the more common form, is characterized both by insulin resistance, a condition in which various tissues in the body no longer respond properly to insulin action, and by subsequent progressive decline in b-cell function to the point that the cells can no longer produce enough additional insulin to overcome the insulin resistance. Researchers are actively exploring cell replacement therapy as a potential strategy to treat type 1 diabetes, because patients with this disease have lost all or nearly all b-cell function. However, if a safe and cost-effective means for replenishing b-cells were developed, such a treatment strategy could also be useful for the larger population with type 2 diabetes. One of the major challenges of cell replacement therapy is the current insufficient supply of b-cells from human organ donors. This article focuses on stem cells as potential sources for deriving new b-cells. Diabetes: A Critical Health Issue for the 21st Century According to the International Diabetes Federation, diabetes currently affects 7% of the world's population nearly 250 million individuals worldwide. 1 This total is expected to rise to 380 million by 2025 as a result of aging populations, changing lifestyles, and a recent worldwide increase in obesity. Although projections for increases in diabetes prevalence suggest that the greatest percentage gains will occur in Asia and South America, 2 , 3 all nations will experience a rising disease Continue reading >>
