News items on 'Stem Cell Transplantation'
(The Scotsman 04/11/2009)
A MOTHER who has frozen her newborn baby's umbilical cord as a health precaution yesterday heralded the move as a "potential life-saver". Paula Aspinall, 34, of Northwich, Cheshire, and her partner, Peter, paid up to £2,000 for the unique insurance policy for themselves, baby Daniel and his three-year-old sister Megan. Samples of tissue and blood from the cord will be stored cryogenically for 20 years with the potential to use the cord's stem cells to repair damaged tissues.
'Ethical' stem cell crop boosted
(BBC 18/10/2009)
US researchers have found a way to dramatically increase the harvest of stem cells from adult tissue. It is a practical step forward in techniques to produce large numbers of stem cells without using embryos. Using three drug-like chemicals, the team made the procedure 200 times more efficient and twice as fast, the Nature Methods journal reported. It is hoped stem cells could one day be widely used to repair damaged tissue in diseases and after injuries.
Jaw bone created from stem cells
(BBC 11/10/2009)
Scientists have created part of the jaw joint in the lab using human adult stem cells. They say it is the first time a complex, anatomically-sized bone has been accurately created in this way. It is hoped the technique could be used not only to treat disorders of the specific joint, but more widely to correct problems with other bones too. The Columbia University study appears in Proceedings of the National Academy of Sciences.
Dying patient saved with his own stem cells and mechanical heart
(The Scotsman 25/09/2009)
A DYING heart patient has been saved after he was given an artificial heart and injected with his own stem cells, a British surgeon said yesterday. The procedure - believed to be a world first - used stem cells in attempts to rebuild the damaged muscle in the heart. Experts welcomed the development, but said more research was necessary before it could be more widely used. Professor Stephen Westaby, based at Oxford's John Radcliffe Hospital, led the team.
Cancer hope over stem cell drug
(BBC 24/08/2009)
Stem cell treatment in cancer patients has been greatly improved by the use of a new drug, clinicians have said. Plerixafor has allowed doctors to collect stem cells from patients where there had been previous difficulties. The drug, which is not yet licensed, is being used at the Beatson West of Scotland Cancer Centre in Glasgow. Stem cells therapies are used to treat people with cancer of the blood. The cells are collected and reintroduced to a patient after chemotherapy.
(The Scotsman 01/08/2009)
A SCIENTIFIC journal has retracted a controversial paper that included claims to have created the first human sperm from embryonic stem cells. Stem Cells and Development's editor was quoted by the science publication Nature as saying that the study by scientists at Newcastle University was retracted because two paragraphs in its introduction had been plagiarised. Newcastle University stressed that the science behind the research, and its conclusions, were not in question.
Hysterectomies a stem cell source
(BBC 18/06/2009)
Discarded fallopian tubes from hysterectomies could be a good source of donor stem cells, say researchers. Work shows they are an abundant source of the immature cells that have the potential to become a variety of the body's tissues, like muscle and bone. The discovery offers another "ethical" route to creating stem cell treatments for diseases like arthritis without using embryos. Other sources include: umbilical cords, menstrual blood, teeth and fat tissue.
Pigs offer new stem cell source
(BBC 03/06/2009)
Chinese scientists have given cells from adult pigs the ability to turn into any tissue in the body, just like embryonic stem cells. They hope the breakthrough could aid research into human disease, and the breeding of animals for organ transplants for humans. It may also enable the development of pigs that are resistant to diseases such as swine flu. The study appears online in the Journal of Molecular Cell Biology.

Stem cell treatment may allow women to delay menopause
(The Independent 13/04/2009)
Women may one day be able to delay the menopause, following a study showing that it is possible to prolong the working life of ovaries by transplanting female stem cells that develop into mature eggs. The findings also raise the prospect of treating some forms of female infertility where the ovaries do not produce eggs. The hope is that one day stem cell transplants could replenish the supply of fresh eggs in infertile women.
