Scientists have created a way to isolate neural stem cells – cells that give rise to all the cell types of the brain – from human brain tissue with unprecedented precision, an important step toward developing new treatments for conditions of the nervous system, like Parkinson’s and Huntington’s diseases and spinal cord injury.
The work by a team of neuroscientists at the University of Rochester Medical Center was published in the Nov. 3 issue of the Journal of Neuroscience. Neurologist Steven Goldman, M.D., Ph.D., chair of the Department of Neurology, led the
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
A research breakthrough has proven that it is possible to reprogram mature cells from human skin directly into brain cells, without passing through the stem cell stage. The unexpectedly simple technique involves activating three genes in the skin cells; genes which are already known to be active in the formation of brain cells at the foetal stage.
The new technique avoids many of the ethical dilemmas that stem cell research has faced.
For the first time, a research group at Lund University in Sweden has succeeded in creating specific types of nerve cells from human skin. By reprogramming connective tissue cells,
University at Buffalo researchers will test the effectiveness of using stem cells from donors to treat patients with heart failure.
The National Heart, Lung and Blood Institute has awarded $2 million for the four-year translational animal study.
The results could pave the way for a similar trial in humans and eventually help make stem cell therapy more widely available (…)
