Researchers in China announced in a paper published in the journal Science on Thursday that they have developed an "easy and safe" way to make stem cells that could rekindle the great hope for growing tissue and organs from stem cells to treat a range of diseases. By using a cocktail of small...
When infections occur in the body, stem cells in the blood often jump into action by multiplying and differentiating into mature immune cells that can fight off illness. But repeated infections and inflammation can deplete these cell populations, potentially leading to the development of serious...
Jack Osbourne, who was diagnosed with multiple sclerosis about a year ago, sat down with Dr. Oz to talk about living with MS, including his decision to adopt a paleo diet (and other controversial therapies) to deal with his illness. More »
Jack Osbourne Goes Paleo And Does Stem Cell Treatment...
Scientists at Oregon Health & Science University and the Oregon National Primate Research Center (ONPRC) have successfully reprogrammed human skin cells to become embryonic stem cells capable of transforming into any other cell type in the body. It is believed that stem cell therapies hold the...
A University of Wisconsin-Madison research group has converted skin cells from people and monkeys into a cell that can form a wide variety of nervous-system cells - without passing through the do-it-all stage called the induced pluripotent stem cell, or iPSC. Bypassing the ultraflexible iPSC...
Stem cells drawn from amniotic fluid show promise for tissue engineering, but it's important to know what they can and cannot do. A new study by researchers at Rice University and Texas Children's Hospital has shown that these stem cells can communicate with mature heart cells and form...
The study, which focuses on the process by which these cells renew and increase in number, could help research to find new treatments. Researchers have found that a protein, which switches on genes to allow embryonic stem cells to self-renew, works better when the natural occurring level of the...
Mammalian females ovulate periodically over their reproductive lifetimes, placing significant demands on their ovaries for egg production. Whether mammals generate new eggs in adulthood using stem cells has been a source of scientific controversy. If true, these "germ-line stem cells" might...
For the first time, human embryonic stem cells have been transformed into nerve cells that helped mice regain the ability to learn and remember. A study at the University of Wisconsin-Madison is the first to show that human stem cells can successfully implant themselves in the brain and then...
Declining levels of the protein BubR1 occur when both people and animals age, and contribute to cell senescence or deterioration, weight loss, muscle wasting and cataracts. Mayo Clinic researchers have shown that adult progenitor or stem cells -- important for repair and regeneration of skeletal...
Deep inside your brain, a legion of stem cells lies ready to turn into new brain and nerve cells whenever and wherever you need them most. While they wait, they keep themselves in a state of perpetual readiness - poised to become any type of nerve cell you might need as your cells age or get...
Research led by a biology professor in the School of Science at IUPUI has uncovered a method to produce retinal cells from regenerative human stem cells without the use of animal products, proteins or other foreign substances, which historically have limited the application of stem cells to...
Researchers at the University of Minnesota's Lillehei Heart Institute have combined genetic repair with cellular reprogramming to generate stem cells capable of muscle regeneration in a mouse model for Duchenne Muscular Dystrophy (DMD)...

New research from the University of Michigan Comprehensive Cancer Center finds that the protein HER2 plays a role even in breast cancers that would traditionally be categorized as HER2-negative - and that the drug Herceptin, which targets HER2, may have an even greater role for treating breast...
Cell therapy is a promising alternative to tissue and organ transplantation for diseases that are caused by death or poor functioning of cells. Considering the ethical discussions surrounding human embryonic stem cells, a lot is expected of the so-called 'induced pluripotent stem cells' (iPS...
Surgeon Paolo Macchiarini has made his name by successfully transplanting bioengineered stem cell-based trachea, composed of both artificial and biological material. He now plans to use the technique to recreate more complex tissues, such as the oesophagus and diaphragm or organs such as the...
A discovery using stem cells from a patient with motor neurone disease could help research into treatments for the condition. The study used a patient's skin cells to create motor neurons - nerve cells that control muscle activity - and the cells that support them called astrocytes. Researchers...
New bone tissue grown from patients' own stem cells that attach themselves to an implanted, rigid lightweight plastic "scaffolding" which gradually degrades and is replaced as new bone grows, could soon be healing shattered limbs, according to a new research report. The degradable polymer...
Scientists have discovered a key protein that kicks off the natural process that differentiates stem cells into any cell of the body. They hope the discovery will help development of therapies for degenerative diseases. The team, from the Medical Research Council Centre for Regenerative...
New research has shown the presence of a disease affecting small blood vessels, known as microangiopathy, in the bone marrow of diabetic patients. While it is well known that microangiopathy is the cause of renal damage, blindness and heart attacks in patients with diabetes, this is the first...
