Stem cell research puts interstate rivalry on holdSeptember 04, 2008Victoria and New South Wales have put aside their competitive interstate rivalry to collaborate on a stem cell research project, as announced by Innovation Minister Gavin Jennings and NSW Minister for Science and Medical Research, Verity Firth, today. Scientists from the Monash Institute of Medical Research (MIMR) and colleagues from New South Wales will compare two different methods of creating patient-specific stem cells: somatic cell nuclear transfer (SCNT) and induced pluripotent stem cells (iPS). SCNT, or therapeutic cloning, is one method used to produce a source of individually-tailored stem cells. One aspect to this project will be to source oocytes, or immature egg cells to generate SCNT embryos from which embryonic stem cells are harvested. Both conventional sources (IVF Clinics) and novel sources (adult ovaries and altruistic donors) will be explored. Unlike SCNT, iPS cells are derived from adult cells, such as skin, which are reprogrammed to behave like embryonic stem cells. Dr Paul Verma, Program Leader of MIMR's Stem Cell Biology Program and the Chief Investigator of the Victorian project team, will create the iPS cells for this project. His lab was the first in Australia to create iPS cells in mouse models. This project will allow him to create human iPS cells in Australia for the first time. "On paper, iPS cells appear to be a preferable alternative to working with human embryonic stem cells, but it's too early to make this assumption. Currently, iPS cell lines show variability in their potential to produce mature cells. If we can overcome this, they could certainly offer a great alternative to embryonic stem cells. "Once our team produces the iPS cells, we will compare the properties of iPS versus cells developed through SCNT. Both methods need to be investigated further so we can determine which will produce the most robust cell lines," Dr Verma said. The NSW project team, led by Professor Bernie Tuch, will investigate another method of obtaining oocytes - from consenting adult cancer patients who have had their ovaries removed. Professor Tuch's team will also use their proficiencies in characterising human embryonic stem cell lines and bioinformatics. Mr Jennings said changes to the Victorian Infertility Treatment Act and the NSW Human Cloning and Other Prohibited Practices Act have opened up new opportunities for stem cell research in Australia. "Australia is already a global leader in overall stem cell research and this new and clear regulatory framework gives us an opportunity to extend our leadership into SCNT which could transform how we treat diabetes, heart diseases and Parkinson's," Mr Jennings said.

This is yet again illustrated by a study carried out by the I-STEM* Institute (I-STEM/ Inserm UEVE U861/AFM), published in the Lancet on 21 November 2009. The I-STEM team, directed by Marc Peschanski has just succeeded in recreating a whole epidermis from human embryonic stem cells. Bone Implant Offers Hope for Skull Deformities A synthetic bone matrix offers hope for babies born with craniosynostosis, a condition that causes the plates in the skull to fuse too soon. Your Own Stem Cells Can Treat Heart Disease The largest national stem cell study for heart disease showed the first evidence that transplanting a potent form of adult stem cells into the heart muscle of subjects with severe angina results in less pain and an improved ability to walk. The transplant subjects also experienced fewer deaths than those who didn't receive stem cells. Is hepatic differentiation of embryonic stem cells induced by valproic acid and cytokines? Embryonic stem (ES) cells, known for their capacity to proliferate indefinitely and differentiate into almost all types of cells including hepatocytes, have raised the hope of cellular replacement therapy for liver failure. Paradoxical protein might prevent cancer One difficulty with fighting cancer cells is that they are similar in many respects to the body's stem cells. By focusing on the differences, researchers at Karolinska Institutet have found a new way of tackling colon cancer. The study is presented in the prestigious journal Cell. U of M researchers find 2 units of umbilical cord blood reduce risk of leukemia recurrence A new study from the Masonic Cancer Center, University of Minnesota shows that patients who have acute leukemia and are transplanted with two units of umbilical cord blood (UCB) have significantly reduced risk of the disease returning. The use of stem cells in regenerative medicine may also be detrimental for health The use of stem cells in regenerative medicine is not always beneficial for human health, it may even be harmful according to a work done by the University of Granada and University of León. Scientists have demonstrated that transplantation of human mononuclear cells isolated from umbilical cord blood exerted a deleterious effect in rats with liver cirrhosis. Penn Study Provides First Clear Idea of How Rare Bone Disease Progresses An international team of scientists, led by researchers at the University of Pennsylvania School of Medicine, is taking the first step in developing a treatment for a rare genetic disorder called fibrodysplasia ossificans progressiva (FOP), in which the body's skeletal muscles and soft connective tissue turns to bone, immobilizing patients over a lifetime with a second skeleton. Iowa State University researcher discovers key to vital DNA, protein interaction A researcher at Iowa State University has discovered how a group of proteins from plant pathogenic bacteria interact with DNA in the plant cell, opening up the possibility for what the scientist calls a "cascade of advances." Scientists successfully reprogram blood cells Researchers have transplanted genetically modified hematopoietic stem cells into mice so that their developing red blood cells produce a critical lysosomal enzyme -preventing or reducing organ and central nervous system damage from the often-fatal genetic disorder Hurler's syndrome.
