Stem Cells News and Research

RSS

Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Researchers discover how microRNA are involved in the development of heart muscle

Researchers at UT Southwestern Medical Center have discovered how a small molecule of RNA called microRNA - a chemical cousin of DNA - helps fine tune the production of a key protein involved in the early development of heart muscle.

First clues as to why stem cells ignore stop signs in the cell cycle

Everyone knows that stem cells are controversial. Many people know that stem cells can grow into virtually any cell type found in the body, from a red blood cell to a muscle cell to a brain cell. But no one really knows why stem cells continue to divide and renew themselves long after the point where other cells stop dividing.

Canada's first two human embryonic stem cell lines

A senior scientist at Mount Sinai Hospital has developed Canada's first two human embryonic stem cell lines, giving researchers across the country new potential and hope for eventually discovering treatments and cures for many chronic and fatal diseases.

Patients with advanced heart failure significantly improved after receiving stem cell therapy

The study showed, 30 days after receiving the stem cells by injection into their hearts, patients improved an average of 41 percent in their hearts' pumping efficiency and the distance they could walk nonstop increased by 72 percent in a standard test widely used to assess heart patients.

U.S. House of Representatives approve two bills on stem-cell research

Two new bills related to stem-cell research have been approved by the U.S. House of Representatives one promoting non-destructive methods and the other supporting research resulting in the death of unborn children.

Protein, called "eed," crucial to the regulation of genes in embryonic stem cells

New research from University of North Carolina at Chapel Hill shows how a protein may be crucial to the regulation of genes in embryonic stem cells.

American Diabetes Association applauds passage of Stem Cell Legislation

The American Diabetes Association has applauded the passage in the U.S. House of Representatives of legislation that would accelerate stem cell research by easing existing restrictions and supporting research that uses embryonic stem cells.

Team IDs mechanism for multiplying adult stem cells

While research on human embryonic stem cells gets most of the press, scientists are also investigating the potential therapeutic uses of adult stem cells. Although less controversial, this research faces other difficulties. Adult stem cells are extremely difficult to isolate and multiply in the lab.

The National Infertility Association joins infertility groups to Support Stem Cell Research Enhancement Act

The National Infertility Association joins with the American Society for Reproductive Medicine (ASRM) and the American Fertility Association in support of the Stem Cell Research Enhancement Act, HR 810.

Stem cell legislation holds promise for 18.2 million Americans with diabetes

The American Diabetes Association today strongly expressed its support for federal legislation that would accelerate stem cell research by easing existing restrictions and supporting research that uses embryonic stem cells.

Major step forward in stem cell research

Newcastle University (England) scientists have taken a major step forward in stem cell research, putting Britain in the vanguard of technology that could produce treatments for a range of conditions such as diabetes, Parkinson’s disease and spinal injuries.

Long-term outcomes studied for stem cell transplant recipients

Improved techniques and supportive care have resulted in a growing number of long-term survivors of stem cell transplants, though little is known about the impact transplants have on patients’ lives long after treatment.

Discovery may lead to new drugs to treat cancer, control fertility

A recent discovery in cellular biology may allow scientists to enhance organ regeneration by stem cells, prevent the progression of cancer, and control fertility.

Crucial to develop set of protections for women who donate eggs to stem cell research

Now that stem cell researchers have devised an efficient way of creating new human embryonic stem cell lines, biomedical ethicists at the Stanford University School of Medicine say it's crucial to develop a unique set of protections for the women who donate their eggs to make the research possible.

Gene keeps neural cells on correct developmental path

Embryonic stem cells with identical genomes grow into distinctive tissues, such as heart, bone, and brain. At one time, scientists believed the differences among cell types arose from various sets of genes switched on inside developing cells. Then, studies showed that adult neurons uniquely lack a protein that permanently turns off neuronal genes in the rest of the body's cells.

Researchers generate patient-specific stem cells

Researchers have isolated the first human embryonic stem cell lines specifically tailored to match the nuclear DNA of patients, both males and females of various ages, suffering from disease or spinal cord injury.

Study holds implications for gene therapy and stem cell biology

The study, conducted by scientists from Cincinnati Children's Hospital Medical Center, and Hannover Medical School and Hamburg University in Germany, reveals important evidence that tells us more about how blood forming stem cells regenerate. On the other hand, scientists offer caution in regards to the side effects associated with genetic engineering of stem cells.

Researchers find first gene for inherited testicular cancer in mice

In this week's journal Nature, researchers report finding the first gene responsible for inherited susceptibility of testicular cancer in mice. The Ter mutation occurs in a gene called dead end, which is involved in normal testicular development and which may play a role in inherited forms of a testicular cancer occurring in infants.

Infants with Krabbe disease saved by cord blood stem cells

Children with a fatal genetic disorder called Krabbe Disease can be saved and their brain development preserved if they receive stem cells from umbilical cord blood before symptoms of the disease develop, according to a study published in the current issue of the New England Journal of Medicine.
