Notes
  • Stem cells are “non-specialized” cells that have the potential to form into other types of specific cells, such as blood, muscles or nerves. They are unlike 'differentiated' cells which have already become whatever organ or structure they are in the body. Stem cells are present throughout our body, but more abundant in a fetus.
    Medical researchers and scientists believe that stem cell therapy will, in the near future, advance medicine dramatically and change the course of disease treatment. This is because stem cells have the ability to grow into any kind of cell and, if transplanted into the body, will relocate to the damaged tissue, replacing it. For example, neural cells in the spinal cord, brain, optic nerves, or other parts of the central nervous system that have been injured can be replaced by injected stem cells. Various stem cell therapies are already practiced, a popular one being bone marrow transplants that are used to treat leukemia. In theory and in fact, lifeless cells anywhere in the body, no matter what the cause of the disease or injury, can be replaced with vigorous new cells because of the remarkable plasticity of stem cells. Biomed companies predict that with all of the research activity in stem cell therapy currently being directed toward the technology, a wider range of disease types including cancer, diabetes, spinal cord injury, and even multiple sclerosis will be effectively treated in the future. Recently announced trials are now underway to study both safety and efficacy of autologous stem cell transplantation in MS patients because of promising early results from previous trials.
    History
    Research into stem cells grew out of the findings of two Canadian researchers, Dr’s James Till and Ernest McCulloch at the University of Toronto in 1961. They were the first to publish their experimental results into the existence of stem cells in a scientific journal. Till and McCulloch documented the way in which embryonic stem cells differentiate themselves to become mature cell tissue. Their discovery opened the door for others to develop the first medical use of stem cells in bone marrow transplantation for leukemia. Over the next 50 years their early work has led to our current state of medical practice where modern science believes that new treatments for chronic diseases including MS, diabetes, spinal cord injuries and many more disease conditions are just around the corner.

  • There was a lacking of the specific medications to be used in the above mentioned conditions. I think it was just an outline.
