Scientists successfully awaken sleeping stem cells
Scientists at Schepens Eye Research Institute have discovered what chemical in the eye triggers the dormant capacity of certain non-neuronal cells to transform into progenitor cells, a stem-like cell that can generate new retinal cells. view more (2008-03-19)
'Smart scaffolds' may help heal broken hearts
Imagine new treatments for heart disease or muscle loss that direct the body to repair damaged tissue rather than helping it cope with a weakened condition. view more (2009-01-13)
Can you hear me now? Stem cells enhance hearing recovery
Researchers have shown that bone marrow stem cells injected into a damaged inner ear can speed hearing recovery after partial hearing loss. view more (2007-06-25)
A master mechanism for regeneration?
Biologists long have marveled at the ability of some animals to re-grow lost body parts. Newts, for example, can lose a leg and grow a new one identical to the original. Zebrafish can re-grow fins. view more (2009-10-20)
Scientists make first step towards growing human lungs for transplant
Scientists have successfully converted human embryonic stem cells into lung cells, taking a first step towards building human lungs for transplantation. view more (2005-08-23)
Digestive specialists freeze out esophagus cancer with new therapy
UT Southwestern Medical Center gastroenterologists are using a new method to freeze damaged cells in the esophagus, preventing them from turning cancerous. view more (2008-07-30)
Einstein researchers discover important clue to the cause of Parkinson's disease
A glitch in the mechanism by which cells recycle damaged components may trigger Parkinson's disease, according to a study by scientists at the Albert Einstein College of Medicine of Yeshiva University. view more (2008-01-03)
Once suspect protein found to promote DNA repair, prevent cancer
An abundant chromosomal protein that binds to damaged DNA prevents cancer development by enhancing DNA repair, researchers at The University of Texas M. D. Anderson Cancer Center report online this week in the Proceedings of the National Academies of Science. view more (2008-07-22)
Inert gas may help stop damaged nerve cells from dying
Scientists from Imperial College London have discovered that xenon gas could help in protecting damaged nerve cells. The research, published today in Anesthesiology, shows that xenon, an inert gas, acts as a neuroprotectant, helping to protect damaged nerve cells from dying. Based upon pre-clinical trials, researchers believe it could have human... view more... (2002-05-29)
Human derived stem cells can repair rat hearts damaged by heart attack
When human heart muscle cells derived from embryonic stem cells are implanted into a rat after a heart attack, they can help rebuild the animal's heart muscle and improve function of the organ, scientists report in the September issue of Nature Biotechnology. view more (2007-08-27)
New research suggests a potentially damaging effect of extremely low frequency electromagnetic fields
The effect of extremely low frequency electromagnetic fields (ELF-EMF), such as those emitted around high-voltage transmission lines on human health, is controversial. Some studies suggest an association between exposure to ELF-EMF and incidence of leukaemia, although little direct evidence exists that exposure causes damage to biological... view more...

Hearing restoration may be possible with cochlear repair after transplant of human cord blood cells
According to an Italian research team publishing their findings in the current issue of Cell Transplantation (17:6), hearing loss due to cochlear damage may be repaired by transplantation of human umbilical cord hematopoietic stem cells (HSC) since they show that a small number migrated to the damaged cochlea and repaired sensory hair cells and... view more...

Bone-marrow Cell Transplantation Could Save Limbs (p 427)
Injecting a patient’s bone-marrow cells into their legs could help repair damaged circulatory systems in those with limb ischaemia, suggest authors of a trial in this week’s issue of THE LANCET. Lower limb ischaemia is due to narrowing of the arteries and is a common condition, which if left untreated can lead to gangrene, amputation,... view more... (2002-08-07)
UF scientists program blood stem cells to become vision cells
University of Florida researchers were able to program bone marrow stem cells to repair damaged retinas in mice, suggesting a potential treatment for one of the most common causes of vision loss in older people. view more (2009-07-31)
Proteasome activator enhances survival of Huntington's disease neuronal model cells
To function, each living cell needs both to build new and to degrade old or damaged proteins. To accomplish that, a number of intracellular systems work in concert to keep the cell healthy and from clogging up with damaged proteins. view more (2007-02-28)
Protein deficit impedes recovery after percutaneous angioplasty
If the body contains too little of the protein haptoglobin, the recovery of the blood vessels after percutaneous angioplasty is impeded. The Utrecht researcher Mirjam Smeets suspects that this is one of the reasons why 40 percent of patients who have undergone percutaneous angioplasty experience a new constriction. view more (2003-01-24)
Stem cell therapy for spinal injury
Researchers at Karolinska Institutet have shown how the transplantation of stem cells improves recovery from spinal injury. However, a painful condition can also develop, which can be prevented if the stem cells are supplemented with a certain gene that controls their maturing process. The results are important for planning of stem cell therapy... view more... (2005-02-13)
Damage from oxygen may be one cause of Parkinson's disease
Research by neuroscientists at the University of Virginia Health System shows that oxygen free radicals are damaging proteins in mitochondria, the tiny cellular 'batteries' of brain cells. view more (2006-05-17)
1 small step for neurons, 1 giant leap for nerve cell repair
The repair of damaged nerve cells is a major problem in medicine today. A new study by researchers at the Montreal NeurologicaI Institute and Hospital (The Neuro) and McGill University, is a significant advance towards a solution for neuronal repair. view more (2009-10-08)
Gladstone scientists identify key factors in heart cell creation
Scientists at the Gladstone Institute of Cardiovascular Disease have identified for the first time key genetic factors that drive the process of generating new heart cells. view more (2009-04-27)
