Stem cells are biological cells found in all multi-cellular organisms, that can divide into diverse specialised cell types and can self-renew to produce more stem cells. Human adult stem cells are routinely used in medical therapies, for example in bone marrow transplants. Stem cells can also be artificially grown and transformed into specialised cell types with characteristics consistent with cells of various tissues such as muscles or nerves.
Two men with HIV have been off Aids drugs for several months after receiving stem-cell transplants for cancer that appear to have cleared the virus from their bodies, researchers reported.Friday, 5 July, 2013, 4:45am
Researchers in Japan have used human stem cells to create tiny human livers like those that arise early in fetal life. When the scientists transplanted the rudimentary livers into mice, the little organs grew, made human liver proteins, and metabolised drugs as human livers do.5 Jul 2013 - 4:45am
US researchers have reported a breakthrough in stem cell research, describing how they have turned human skin cells into embryonic stem cells for the first time.17 May 2013 - 12:29am
Imagine this: a car crash victim who suffers serious trauma to the brain avoids neurological damage after the doctors regenerate his lost brain matter using stem cells in the lab.19 Feb 2013 - 10:19am

Work out now and continue to reap the benefits later. A new study in the United States has found that having a higher fitness level in midlife appears to be associated with a lower risk of developing Alzheimer's disease and other types of dementia in later years.18 Feb 2013 - 5:06pm
Researchers are a step closer to developing therapies for the deadly condition, known as arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C).29 Jan 2013 - 11:35am
Researchers in Japan said on Wednesday they have succeeded in growing human kidney tissue from stem cells for the first time in a potential breakthrough for millions with damaged organs who are dependent on dialysis.23 Jan 2013 - 6:24pm
Researchers are reporting that stem cells donated by strangers proved as safe and effective as patients' own cells for helping restore heart tissue, a key advance in repairing hearts damaged by heart attacks.7 Nov 2012 - 4:10am
British scientist John Gurdon, awarded the Nobel Medicine Prize on Monday, admitted he had done the bulk of the cell programming work for which he was honoured half a century ago.
The 79-year-old, with a shock of swept-back greying blond hair, held a hastily-arranged press conference in London, just hours after being telephoned by the Nobel academy with the news of his award.29 Aug 2013 - 4:13am
The sales pitch of the blood bank is something first-time mother Mrs Leung couldn't ignore. When she gave birth to her son at Union Hospital last year, she was told her child's umbilical cord was rich with stem cells that may have the potential to treat Alzheimer's disease and traumatic brain injury in the future.18 Sep 2012 - 7:49am
A member of the Chinese Academy of Sciences who helped draft the mainland's first regulations on clinical trials of stem cell treatments says the authorities are considering centralising such treatment and research in 50 hospitals and institutes.10 Jul 2012 - 12:00am
