Stem cell treatments: Recently, in Atlanta, USA, in the first case of its kind on US soil, a patient was treated with human embryonic stem cells. The treatment is approved by the Food and Drug Administration. In UK, researchers are getting ready for the first test of an embryonic stem cell-based treatment on patients. The test would take place in 2012. They are still awaiting the permission from Medicines and Healthcare products Regulatory Agency (MHRA), but are quite sure that the approvals would be given. Stem cells are cells that are found in all multicellular organisms. Stem cell exhibits two characters, their self-renewal capacity and potency to differentiate into specialized cell types. Stem cells can be divided into embryonic stem cells and adult stem cells. Though medical researchers believe that stem cells have the potential to revolutionize the human treatment, stem cell research has not yet reached its full potential. Adult stem cell therapies are in use. The...
