Stem cell therapy reverses diabetes
Type 1 diabetes is caused by the body's own immune system attacking its pancreatic islet beta cells and requires daily injections of insulin to regulate the patient's blood glucose levels. A new method described in BioMed Central's open access journal BMC Medicine uses stem cells from cord blood to re-educate a diabetic's own T cells and consequently restart pancreatic function reducing the

Flexible adult stem cells, right there in your eye
In the future, patients in need of perfectly matched neural stem cells may not need to look any further than their own eyes. Researchers reporting in the January issue of Cell Stem Cell, a Cell Press publication, have identified adult stem cells of the central nervous system in a single layer of cells at the back of the eye.

Aging-related degeneration caused by defects of energy metabolism in tissue stem cells?
Aging-related tissue degeneration can be caused by mitochondrial dysfunction in tissue stem cells.

How work tells muscles to grow
We take it for granted, but the fact that our muscles grow when we work them makes them rather unique. Now, researchers have identified a key ingredient needed for that bulking up to take place. A factor produced in working muscle fibers apparently tells surrounding muscle stem cell "higher ups" that it's time to multiply and join in, according to a study in the January Cell Metabolism, a C

A shot of young stem cells made rapidly aging mice live longer and healthier
Mice bred to age too quickly seemed to have sipped from the fountain of youth after scientists at the University of Pittsburgh School of Medicine injected them with stem cell-like progenitor cells derived from the muscle of young, healthy animals. Instead of becoming infirm and dying early as untreated mice did, animals that got the stem/progenitor cells improved their health

How do you mend a broken heart?
Damaged heart tissue is not known for having much inherent capacity for repair. But now, scientists are closing in on signals that may be able to coax the heart into producing replacement cardiac muscle cells. Using a zebrafish model system, researchers have identified a family of molecules that can stimulate stem cells to develop into beating heart muscle cells. The research, published by Cell Pr

Regeneration of specialized cells offers hope for treating chronic kidney disease
Damage to podocytes -- a specialized type of epithelial cell in the kidney -- occurs in more than 90 percent of all chronic kidney disease. Now researchers at the Stanford University School of Medicine have uncovered an unexpected pathway that reveals for the first time how these cells may regenerate and renew themselves during normal kidney function.

Newly discovered heart stem cells make muscle and bone
Researchers have identified a new and relatively abundant pool of stem cells in the heart. The findings in the December issue of Cell Stem Cell, a Cell Press publication, show that these heart cells have the capacity for long-term expansion and can form a variety of cell types, including muscle, bone, neural and heart cells.

Researchers engineer blood stem cells to fight melanoma
Researchers from UCLA's cancer and stem cell centers have demonstrated for the first time that blood stem cells can be engineered to create cancer-killing T-cells that seek out and attack a human melanoma. The researchers believe this approach could be useful in 40 percent of Caucasians with this malignancy.

The possibility that functional, three-dimensional tissues and organs may be derived from pluripotent cells, such as embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), represents one of the grand challenges of stem cell research, but is also one of the fundamental goals of the emerging field of regenerative medicine.

New method for producing precursor of neurons, bone and other important tissues from stem cells
In principle, stem cells offer scientists the opportunity to create specific cell types—such as nerve or heart cells—to replace tissues damaged by age or disease. In reality, coaxing stem cells to become the desired cell type can be challenging, to say the least.

Tales from the crypt
The lining of the intestine regenerates itself every few days as compared to say red blood cells that turn over every four months. The cells that help to absorb food and liquid that humans consume are constantly being produced. The various cell types that do this come from stem cells that reside deep in the inner recesses of the accordion-like folds of the intestines, called villi a

Embryonic signal drives pancreatic cancer and offers a way to kill it
Pancreatic cancer is a particularly challenging one to beat; it has a tendency to spread and harbors cancer stem cells that stubbornly resist conventional approaches to therapy. Now, researchers reporting in the November issue of Cell Stem Cell, a Cell Press publication, have evidence to suggest there is a way to kill off those cancer stem cells.

Scientists find stem cell reprogramming technique is safer than previously thought
Stem cells made by reprogramming patients' own cells might one day be used as therapies for a host of diseases, but scientists have feared that dangerous mutations within these cells might be caused by current reprogramming techniques. A sophisticated new analysis of stem cells' DNA finds that such fears may be unwarranted.
