Solution
- Stem cell research has the potential of bringing about fundamental changes in the medical science.
- Stem Cell therapy has the following applications:
a. Cell therapy: In case of medical conditions like myocardial infarction, diabetes, Alzheimer’s disease, Parkinson’s disease, etc., stem cells are used to replace dead cells.
b. In conditions like anemia, thalassemia and leukemia, where blood count is affected, stem cells are used to produce new blood cells. This is known as regenerative cell therapy.
c. Organ transplantation: Advances in research may make it possible to produce organs like liver or kidney from stem cells to be used for transplantation in case of organ failure.
Hence, it is rightly said that the revolutionary phenomenon in biotechnology after cloning is stem cell research.
