Stem cells have tremendous promise to help us understand and treat a range of diseases, injuries and other health-related conditions. Their potential is evident in the use of blood stem cells to treat diseases of the blood, a therapy that has saved the lives of thousands of children with leukemia; and can be seen in the use of stem cells for tissue grafts to treat diseases or injury to the bone, skin and surface of the eye. Important clinical trials involving stem cells are underway for many other conditions and researchers continue to explore new avenues using stem cells in medicine.
There is still a lot to learn about stem cells, however, and their current applications as treatments are sometimes exaggerated by the media and other parties who do not fully understand the science and current limitations.
Different types of stem cells come from different places in your body and have different functions. Scientists are exploring the different roles tissue-specific stem cells might play in healing, with the understanding that these stem cells have specific and limited capabilities. Without manipulation in the lab, tissue-specific stem cells can only generate the other cell types found in the tissues where they live. For example, the blood-forming (hematopoietic) stem cells found in bone marrow regenerate the cells in blood, while neural stem cells in the brain make brain cells. A hematopoietic stem cell won’t spontaneously make a brain cell and vice versa. Thus, it is unlikely that a single cell type can be used to treat a multitude of unrelated diseases involving different tissues or organs.
