Stem cell researcher Dr. Ann Kiessling announced today the discovery of cell characteristics that may explain important differences between embryonic stem cells and adult stem cells. Scientists have for years been frustrated in their efforts to grow the trillions of adult stem cells needed for therapies, which is why embryonic stem cells seem promising — they can multiply endlessly and also develop into any cell in the body.
Kiessling discovered that early human embryo cells express CLOCK, and other circadian genes, that other human cells growing in laboratories did not. This was a surprise. Although scientists have recently
A team of researchers at the UC Davis Institute for Regenerative Cures has developed a technique for using stem cells to deliver therapy that specifically targets the genetic abnormality found in Huntington’s disease, a hereditary brain disorder that causes progressive uncontrolled movements, dementia and death. The findings, now available online in the journal Molecular and Cellular Neuroscience, suggest a promising approach that might block the disease from advancing.
“For the first time, we have been able to successfully deliver inhibitory RNA sequences from stem cells directly into neurons, significantly decreasing the synthesis of the abnormal huntingtin protein,” said Jan A.
A team of researchers has now compared the ability of cells derived from different types of human stem cell to reverse disease in a rat model of Parkinson disease and identified a stem cell population that they believe could be clinically relevant.
Parkinson disease results from the progressive loss of a specific subpopulation of nerve cells. Current treatments provide only relief from the symptoms of the disease and cannot reverse the nerve cell loss.
Stem cells are considered by many to be promising candidate sources of cells to reverse nerve cell loss in individuals with Parkinson disease through their ability to
Parkinson’s Disease – Medical world has struggled in finding permanent cure for this condition that usually affects men over the age of 50 years, but now this maybe changing with the advent of stem cell based research in regenerative medicine. A significant clinical human trial using these technique now seems feasible in the near future.
Stem Cells and its Potential:
Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish
Dr Foteini Hassiotou has discovered stem cells can be obtained from breast milk
Serious and fatal diseases such as pancreatic cancer, Parkinson‘s disease and diabetes may eventually be treated using stem cells from breast milk following a remarkable discovery at the University of Western Australia.
UWA PhD student Foteini Hassiotou has potentially broken through the greatest hurdle in stem cell research – the ability to ethically obtain stem cells in a non-invasive manner.
Her finding that stem cells from breast milk can be directed to become other body cell types such as bone, fat, liver and brain cells, could reduce the
