Brain cells help neighboring nerves regenerate
Researchers have uncovered a completely unexpected way that the brain repairs nerve damage, wherein cells known as astrocytes deliver a protective protein to nearby neurons. view more (2008-05-28)
U of Alberta study discovers how proteins help repair DNA
A person's DNA is often damaged by a number of different chemical contaminants, and if not repaired properly, it can lead to the development of cancer and other diseases. view more (2009-06-16)
New research helps explain genetics of Parkinson's disease
A new study by Narendra et al. suggests that Parkin, the product of the Parkinson's disease-related gene Park2, prompts neuronal survival by clearing the cell of its damaged mitochondria. view more (2008-11-24)
Stem cell breakthrough gives new hope to sufferers of muscle-wasting diseases
An experimental procedure that dramatically strengthens stem cells' ability to regenerate damaged tissue could offer new hope to sufferers of muscle-wasting diseases such as myopathy and muscular dystrophy, according to researchers from the University of New South Wales (UNSW). view more (2009-03-05)
Advances In Curing Corneal Illnesses Using Stem Cells
The University School of Clinical Medicine has developed a new technique for the treatment of corneal illnesses. It involves transplanting from the cornea stem cells which have previously been grown in the laboratory. According to the explanation provided by Doctor Javier Moreno, director of Ophthalmology and Doctor Felipe Pr'³sper, responsible... view more... (2004-02-16)
U of MN uses robotic surgery techniques in cardiac cell therapy research
Researchers at the University of Minnesota were successful in using robotic surgery to deliver stem cell treatment to damaged heart tissue in pigs. view more (2006-08-01)
Mice could provide the key to growing human lungs for transplant
Scientists from Imperial College London have successfully directed mouse stem cells to turn into the type of cells needed for gas exchange in lungs, bringing the prospect of being able to regenerate damaged lung tissue, and even the creation of artificially grown lungs one step closer. Dr Anne Bishop, from Imperial College Tissue Engineering and... view more... (2002-05-15)
Bone marrow cell transplants help nerve regeneration
A study carried out by researchers at the Kyoto University School of Medicine and published in the current issue of CELL TRANSPLANTATION (Vol.16 No. 8) has shown that when transplanted bone marrow cells (BMCs) containing adult stem cells are protected by a 15mm silicon tube and nourished with bio-engineered materials, they successfully help... view more...

Stem cells as cancer therapy
It is widely hoped that neural stem cells will eventually be useful for replacing nerves damaged by degenerative diseases like Alzheimer disease and multiple sclerosis. But there may also be another use for such stem cells-delivering anti-cancer drugs to cancer cells. view more (2006-12-26)
Sight for sore eyes
In a world-first breakthrough, University of New South Wales (UNSW) medical researchers have used stem cells cultured on a simple contact lens to restore sight to sufferers of blinding corneal disease. view more (2009-06-10)
Biocompatibility to Ensure Body Friendly Parts
In recent years, the solution to the problem of diseased or damaged organs has been to replace the old with the new. By taking tissue from either a patient or a donor, surgeons have transplanted this to the damaged area and given many people a new lease of life. The method is not without limitations, however. Issues such as the availability of... view more... (2003-06-06)
Human stem cell transplants mature into neurons and make contacts in rat spinal cord
Human nerve stem cells transplanted into rats' damaged spinal cords have survived, grown and in some cases connected with the rats' own spinal cord cells in a Johns Hopkins laboratory, overturning the long-held notion that spinal cords won't allow nerve repair. view more (2007-02-14)
New cell culturing method pumps up the volume
In a breakthrough that will likely accelerate research aimed at cures for hearing loss, tinnitus, and balance problems, scientists have perfected a laboratory culturing technique that provides a reliable new source of cells critical to understanding certain inner-ear disorders. view more (2007-09-25)
Refusal of suicide order: Why tumor cells become resistant
Cells with irreparable DNA damage normally induce programmed cell death, or apoptosis. However, this mechanism often fails in tumor cells so that transformed cells are able to multiply and spread throughout the body. view more (2008-06-24)
Stem cell treatment succeeds in spinal cord-injured rats
Stem cells can repair damaged spinal tissue and help restore function in rats with spinal cord injuries, according to a new study. view more (2006-03-29)
Researchers identify major source of muscle repair cells
In a surprising discovery with implications for treating muscular dystrophy, researchers at the University of Utah School of Medicine and other institutions have identified a major source of origin for two groups of adult cells that regulate muscle repair. view more (2006-01-30)
UT Southwestern 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 (2008-07-29)
A cancer gene causing tumours by a 'double-whammy' mechanism also reveals the key to a cure
Scientists at the Babraham Institute have discovered that a tiny change in a protein involved in cell survival is responsible for abnormal cell activity in the early stages of cancer. The protein, known as Bcl-xL, normally protects cells from dying; and when the DNA in cells becomes damaged, Bcl-xL is modified so that it no longer keeps the cells... view more... (2004-01-21)
Chemistry & Industry - 15 July Issue
NEWS Nicotine may be answer to growing organs (page 4) Nicotine may prove to be the only thing that can facilitate the growth of an organ intact in the body, according to research by scientists in the US. They have shown that, in very low doses, nicotine can stimulate blood-vessel growth in damaged, blood-starved tissue, as well as recruit and... view more... (2002-07-11)
Chromosome glue repairs damaged DNA
When a strand of DNA breaks in the body's cells, it normally does not take long until it has been repaired. Now researchers at the Swedish medical university Karolinska Institutet have discovered a new mechanism that helps to explain how the cell performs these repairs. The results are presented in Science. view more (2007-07-16)
