New stem cell line for diabetes
Australian researchers have developed the country's first diabetes specific stem cell line, a major advance for patients suffering from the chronic disease.
Innovation Minister Gavin Jennings announced the breakthrough to coincide with the AusBiotech Conference being held in Melbourne.
The new stem cell line was generated through induced pluripotent stem (iPS) cell technology using skin cells from Type I diabetes patients without the use of embryos, eggs or cloning.
Monash Institute of Medical Research (MIMR) and the Sydney Cell Therapy Foundation have developed the line with $455,450 backing from the Victorian and NSW Stem Cell Research Grant Program.
Mr Jennings said the diabetes-specific iPS cell line was a significant achievement that would open the door to developing new therapies and eventually drugs to slow or stop diabetes.
"Diabetes is the fastest growing chronic disease in Australia affecting 1.5 million Australians and the nation's sixth leading cause of death which is why the Brumby Labor Government is committed to improving the quality of life of those who suffer from the illness," Jennings said.
"Australia's first iPS cell line is another example of how our world-leading stem cell researchers have the skills and expertise to take up novel stem cell technology that has global implications."
The iPS technique reprograms a normal cell – such as a skin cell – using 3 to 4 genes added to the cell via viruses. The iPS cells behave like embryonic stem cells but do not use embryos, eggs, or cloning, avoiding any need to create, destroy, or harm any human embryos.
"Thanks to this breakthrough, Australian researchers and companies are now able to study the development of the disease in petri dishes, outside of the patients," Jennings said.
The Victorian and New South Wales Stem Cell Research Grant Program was created to develop new stem cell technologies to treat diseases like Parkinson's, Alzheimer's, cancer, heart disease, spinal cord injury and diabetes.
The program has funded two projects: the collaboration between the Monash Institute of Medical Research and Sydney Cell Therapy Foundation and the Australian Stem Cell Centre and Sydney IVF Ltd.
Dr Paul Verma, researcher at the Monash Institute of Medical Research said it is still too early to assume iPS cells are the preferable alternative to working with embryonic stem cells.
"We don't know whether iPS cells and Embryonic Stem cells will recapitulate the disease in the same way which is why it is important for researchers to have a range of approaches to use in the development of new treatments for diseases such as diabetes," he said.
