Why Stem Cell Research Is Being Pursued
Currently, the expanding list of stem cell-based therapies gives researchers hope that someday stem cells will enable scientists to develop treatments and cures for diseases previously thought to be incurable. There are major diseases that are caused by the loss of, or damage to, a specialized cell or tissue. Currently, scientists are doing research and clinical trials to find a cure for Type I diabetes, which is caused by the loss of specialized cells in the pancreas that produce insulin. Today, treatment consists of administering insulin shots, which only addresses the symptoms. Finding a cure for this and many other diseases would be much easier if scientists could use stem cells to repair or re-grow the missing or damaged cells and deliver them, using various techniques, to the affected area of the patient’s body.
