Stem cell therapy is the use of stem cells to deal with or avoid a disease or problem. Bone marrow transplant is the most extensively utilized stem-cell therapy, but some therapies derived from umbilical cord blood are also in use. Research is underway to build a variety of sources for stem cells, as nicely as to apply stem-cell treatment options for neurodegenerative illnesses and circumstances this kind of as diabetes and heart disease, among other people.
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 produce stem cells using somatic cell nuclear transfer and their use of strategies to produce induced pluripotent stem cells. This controversy is frequently relevant to abortion politics and to human cloning. Additionally, efforts to market place treatment options based on transplant of stored umbilical cord blood have been controversial.
For above thirty years, bone marrow has been utilized to deal with men and women with cancer with circumstances this kind of as leukaemia and lymphoma this is the only kind of stem-cell therapy that is extensively practiced. For the duration of chemotherapy, most increasing cells are killed by the cytotoxic agents. These agents, nevertheless, are not able to discriminate amongst the leukaemia or neoplastic cells, and the hematopoietic stem cells inside of the bone marrow. It is this side effect of typical chemotherapy approaches that the stem-cell transplant attempts to reverse a donor’s healthful bone marrow reintroduces functional stem cells to change the cells lost in the host’s body in the course of treatment. The transplanted cells also create an immune response that helps to destroy off the cancer cells this method can go too far, nevertheless, major to graft vs host disease, the most critical side effect of this treatment.
One more stem cell therapy known as Prochymal, was conditionally accepted in Canada in 2012 for the management of acute graft-vs-host disease in kids who are unresponsive to steroids. It is an allogenic stem therapy based on mesenchymal stem cells (MSCs) derived from the bone marrow of grownup donors. MSCs are purified from the marrow, cultured and packaged, with up to 10,000 doses derived from a single donor. The doses are stored frozen right up until needed.
The FDA has accepted 5 hematopoietic stem-cell goods derived from umbilical cord blood, for the treatment of blood and immunological illnesses.
In 2014, the European Medicines Agency recommended approval of limbal stem cells for men and women with extreme limbal stem cell deficiency due to burns in the eye.
