Stem cell therapy is the use of stem cells to deal with or avoid a illness or problem. Bone marrow transplant is the most broadly utilized stem-cell therapy, but some therapies derived from umbilical cord blood are also in use.

Stem-cell therapy has grow to be controversial following developments this kind of as the potential of scientists to isolate and culture embryonic stem cells, to develop stem cells utilizing somatic cell nuclear transfer and their use of techniques to develop induced pluripotent stem cells. This controversy is usually relevant to abortion politics and to human cloning. Furthermore, efforts to market place remedies primarily based on transplant of stored umbilical cord blood have been controversial.

For more than thirty many years, bone marrow has been utilised to deal with folks with cancer with circumstances this kind of as leukaemia and lymphoma this is the only type of stem-cell therapy that is broadly practiced.

An additional stem cell therapy called Prochymal, was conditionally approved in Canada in 2012 for the management of acute graft-vs-host illness in youngsters who are unresponsive to steroids. It is an allogenic stem therapy primarily based on mesenchymal stem cells (MSCs) derived from the bone marrow of adult donors. MSCs are purified from the marrow, cultured and packaged, with up to ten,000 doses derived from a single donor. The doses are stored frozen until essential.

The FDA has approved five hematopoietic stem-cell merchandise derived from umbilical cord blood, for the treatment of blood and immunological diseases.
