Have human embryonic stem cells been used successfully to treat any human diseases yet?
Scientists have only been able to do experiments with human embryonic stem cells (hESC) since 1998, when a group led by Dr. James Thomson at the University of Wisconsin developed a technique to isolate and grow the cells. Moreover, federal funds to support hESC research have been available since August 9, 2001, when President Bush announced his decision on federal funding for hESC research. Because many academic researchers rely on federal funds to support their laboratories, they are just beginning to learn how to grow and use the cells. Thus, although hESC [may someday] offer potential cures and therapies for many devastating diseases, research using them is still in its early stages.
Adult stem cells such as blood-forming stem cells in bone marrow (called hematopoietic stem cells, or HSCs) are currently the type of stem cell commonly used to treat human diseases.
Doctors have been transferring HSCs in bone marrow transplants for over 40 years.
More advanced techniques of collecting, or "harvesting", HSCs are now used in order to treat leukemia, lymphoma and several inherited blood disorders.
The clinical potential of adult stem cells has also been demonstrated in the treatment of other human diseases that include diabetes and advanced kidney cancer. [NIH]
Adult stem cells (non-embryonic) are stem cells harvested from the human body of an adult or child; they are not harvested by destroying a human embryo, as happens in embryonic stem cell research.
Adult stem cells, placental cells, and umbilical cord stem cells are non-embryonic stem cells.
Presently, these non-embryonic stem cells have provided successful human treatments for over 70 human diseases/conditions. Visit www.stemcellresearch.org for updates.
