Adult Stem/progenitor Cells Repair Of Damaged Brain, Pancreas, Kidney Cells Newly Understood
Source: Federation of American Societies for Experimental Biology
Date: April 29, 2007
Summary:
New studies by Tulane University researchers are shedding light on the previously mysterious mechanism through which even relatively small amounts of stem/progenitor cells taken from a patient’s own bone marrow enhance repair of damaged tissues. The cells not only differentiate to replace injured cells, as had been understood, but they also stimulate the proliferation and differentiation of stem cells already present in the injured tissue. The study's lead author says better understanding of the different mechanisms of these stem/progenitor cells suggests multiple strategies for developing new therapies for a broad range of diseases. It also may help make such treatments more effective and minimize potential dangers.

STEM CELL RESEARCH OPENS NEW DOORS: If replacement therapy doesn't cure disease, it unlocks mysteries of how neurons operate
Source: San Francisco Chronicle
Date: April 16, 2007
Summary:
One argument for stem cell research is that it might generate fresh replacement cells for those destroyed by such horrific diseases as ALS, the paralyzing nervous system disorder popularly known as Lou Gehrig's disease. The latest research suggests those predictions might be unrealistic: Replacing cells that die off in a disease still leaves open the question of why the cells died in the first place, which is the critical issue in any autoimmune disease, or degenerative diseases such as Alzheimer's or Parkinson's. The findings may be the most dramatic example yet of the idea that stem cells are more valuable as a "disease model" -- used to study disease -- rather than a simple source of replacement parts.

Summary:
One argument for stem cell research is that it might generate fresh replacement cells for those destroyed by such horrific diseases as ALS, the paralyzing nervous system disorder popularly known as Lou Gehrig's disease. The latest research suggests those predictions might be unrealistic: Replacing cells that die off in a disease still leaves open the question of why the cells died in the first place, which is the critical issue in any autoimmune disease, or degenerative diseases such as Alzheimer's or Parkinson's. The findings may be the most dramatic example yet of the idea that stem cells are more valuable as a "disease model" -- used to study disease -- rather than a simple source of replacement parts.

Diseased Brain Cells More Involved In ALS-associated Motor Neuron Death
Source: Columbia University Medical Center
Date: April 15, 2007
Summary:
Two papers by Columbia and Harvard researchers report for the first time that astrocytes (the most abundant non-neuronal cells in the central nervous system), which carry a mutated gene known to cause some cases of amyotrophic lateral sclerosis (ALS/Lou Gehrig’s disease), induce motor neuron death. This indicates that astrocytes may contribute to ALS by releasing a toxic factor that damages neurons. These findings, posted online by Nature Neuroscience on April 15, suggest that developing an effective therapy for ALS would require overcoming the destructive effects of astrocytes and replacing the damaged motor neurons, possibly by transplanting motor neurons derived from embryonic stem cells.

Summary:
In a first step towards creating artificial sperm cells, researchers have turned human bone marrow tissue into primitive sperm cells. If these precursor cells can be coaxed into becoming fully functioning sperm cells, the technique could allow infertile men to father their own children, and even allow women to produce their own sperm. But experts caution that provoking the sperm precursors to fully mature presents a serious challenge.

Key Player In Embryonic Muscle Development Discovered
Source: Weizmann Institute of Science
Date: April 11, 2007
Summary:
Muscle fibers are large cells that contain many nuclei. They begin, like all animal cells, as naive embryonic cells. These cells differentiate, producing intermediate cells called myoblasts that are now destined to become muscle. New myoblasts then seek out other myoblasts, and when they find each other, they stick together like best friends. In the final stage of muscle fiber development, the cell membranes of attached myoblasts open up and fuse together, forming one large, unified cell. How myoblasts identify other myoblasts and how they cling together had been established, but the way that the cell membranes fuse into one has remained a mystery. Now, a study by Weizmann Institute scientists has shed light on this mystery.

Date: April 11, 2007
Summary:
MIT Technology Review reports on the new study carried out by researchers at the University of Sao Paulo, in Brazil, and Northwestern University, in Chicago, using adult stem cells to treat type 1 diabetes:
"A combination of stem cells derived from patients' blood and immunosuppression to eliminate a faulty immune system can help keep newly diagnosed diabetics off insulin, according to a preliminary study published today. The findings, which still need to be verified in larger groups, are part of a growing effort to use immunotherapy to halt the progress of Type 1 diabetes."
The story continues:
"Previous studies of antibodies that block destructive immune cells have shown success for a limited period of time. The new study, which combines immunotherapy and stem-cell transplants, seems to improve beta-cell function. The combination therapy has previously been used in other autoimmune disorders, such as lupus, but this is the first trial that tests it in diabetes."
Commentary: Replication of this finding over a large and heterogeneous population that is monitored over a long time will be important in order to determine how effective it is in treating patients.

Summary:
WebMD covers the new finding that may have implications for treating Type 1 diabetes:
"After transplants of their own blood stem cells, 14 of 15 type 1 diabetes patients are insulin free for one to 36 months -- and counting, according to a new studying by researchers at f the University of São Paulo, Brazil. The finding marks the first time the treatment has been used in type 1 diabetes, although it's helped patients with other autoimmune diseases. The early success is encouraging -- but nobody is using the word 'cure.'"
"Researchers caution it is still unclear exactly how the stem cell treatment works, or even whether it truly works at all. And it's far from clear how long treated patients will remain insulin free. They warn that longer follow-up of trial patients, further biological studies, and a clinical trial will be needed to confirm that the treatment works. Their report appears in the April 11 issue of The Journal of the American Medical Association."

Study suggests use of stem cell transplantation is beneficial treatment of type 1 diabetes
Source: JAMA and Archives Journals
Date: April 10, 2007
Summary:
A therapy that includes stem cell transplantation induced extended insulin independence in patients with type 1 diabetes mellitus (DM), according to a preliminary study in the April 11 issue of the Journal of the American Medical Association (JAMA). Researchers at the University of São Paulo, Ribeirão Preto, Brazil, in collaboration with the Northwestern University Feinberg School of Medicine, Chicago conducted a study to examine the effect of high-dose immunosuppression followed by transplanting a patient's own hematopoietic (bone marrow) stem cells to preserve function of pancreatic beta-cells in 15 newly diagnosed patients with type 1 DM. During a long-term follow-up, 14 patients became insulin-free (one for 35 months, four for at least 21 months, seven for at least six months; and two with late response were insulin-free for one and five months, respectively). Further follow-up is necessary to confirm the duration of insulin independence and the mechanisms of action of the procedure.

Summary:
Diabetics appear to have been cured with a one-off treatment that rebuilds their immune system, according to a new study published in the Journal of the American Medical Association (vol 297, p 1568). The technique, which uses patients' own bone marrow cells, has freed 14 of 15 patients with type 1 diabetes from their dependence on insulin medication. So far, participants in the trial have gone 18 months without insulin therapy following the procedure, on average. One patient has lasted three years without needing such injections.

Summary:
Stem cells taken from the blood of a few diabetes patients have "re-set" their immune systems, helping 14 out of 15 live for months and even years without insulin, researchers reported. While they are not claiming to have cured the patients, they said their experiment shows it may be possible to at least interrupt the mistaken immune response that destroys insulin-producing cells in type-1 diabetes.

Joslin study indicates insulin receptors play a critical role in promoting islet growth
Source: Joslin Diabetes Center
Date: April 2, 2007
Summary:
A new Joslin-led study has identified the insulin receptor as an important protein that promotes islet cell growth in mice whose bodies are unable to use insulin properly, or are insulin resistant, a precursor to type 2 diabetes. Since the body's natural response to insulin resistance is to increase insulin secretion from the pancreas and grow more islet cells, also known as beta cells, harnessing this growth response could lead to new treatments for type 2 diabetes. The study appears in the early online edition of this week's Proceedings of the National Academy of Sciences.
