Roslin experts reveal major stem-cell breakthrough
ALAN RODEN HEALTH REPORTER ( )
A MAJOR scientific breakthrough in stem cell research was today revealed by
Lothian experts in a move that could lead to huge advances in medical
treatment.
For the first time, scientists from Roslin have managed to create new stem
cells from a clinically unusable human egg.
In the long-term, the development could have major implications for research
into illnesses such as Alzheimer's, Parkinson's, liver disease and diabetes
as well as offering hope to infertile couples.
The breakthrough was made by Roslin Cells Limited, a spin-off company from
the world-famous Roslin Institute in Midlothian.
Until now, eggs used in research that failed to fertilise - and could not
develop into a viable human embryo - were routinely discarded.
But with a major shortage of embryos available for research, today's
announcement means these eggs could now still be used to produce embryonic
stem cells.
Stem cell researchers can study diseases and develop new treatments, such as
drugs for the prevention of illnesses like cancer.
Because of their potentially unlimited capacity for self-renewal, embryonic
stem cell therapies have been proposed for regenerative medicine and tissue
replacement after injury or disease - although to date, there are no
approved medical treatments.
Speaking at the annual meeting of the International Society for Stem Cell
Research in Australia, Dr Paul De Sousa - Roslin Cells' chief scientific
officer - said: "Typically up to 30 per cent of eggs in an IVF treatment
cycle will be unusable as they fail to fertilise or do so abnormally.
"These eggs could not develop into a viable embryo and are therefore
normally discarded in routine IVF treatment.
"Until now, it has been thought that they are also incapable of producing
embryonic stem cells.
"My team at Roslin Cells has been working with colleagues at the Central
Manchester and Manchester Children's University Hospitals Trust and the
University of Manchester, to develop techniques to stimulate these eggs so
that the cells divide and develop.
"Shortly after this process starts, we are able to extract embryonic stem
cells. The new cell line which we have produced in this way, demonstrates
that embryonic stem cells can be produced from tissue which was previously
not considered of use to stem cell research."
Funding to support the work carried out by Roslin Cells and the team in
Manchester was provided by the UK Medical Research Council.
Roslin Cells was established last year with initial funding of £1.7 million
from Scottish Enterprise Edinburgh and Lothian, with support from Edinburgh
University and the Scottish National Blood Transfusion Service.
The body is designed to consolidate the expertise developed by the Roslin
Institute, where scientists created Dolly the sheep - the first mammal to be
cloned from an adult cell.
Dave Anderson, senior director of operations at Scottish Enterprise
Edinburgh and Lothian, said: "This development is another demonstration of
the world-class scientific expertise that we have in Scotland and its
potential to grow Scotland's economy.
"It not only has the potential to transform the lives of people suffering
from some of the most debilitating conditions but also to maintain
Scotland's position as a global leader in regenerative medicine."
