Task 6 – Stem Cells

           Embryonic stem cells are derived from embryos that develop from eggs that have been fertilized in an  clinic, and then donated for research purposes with the consent of the donors. The  are derived are typically four or five days old and are a hollow microscopic ball of cells called the .

            Stem cells have the remarkable potential to develop into many different cell types in the body. Serving as a sort of repair system for the body, they can theoretically divide without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential to either remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell. Large numbers of embryonic stem cells can be relatively easily grown in culture, while adult stem cells are rare in mature tissues and methods for expanding their


         A stem cell has been found in adults that can turn into every single tissue in the body. It might turn out to be the most important cell ever discovered.  Stem cells are considered a potential magic bullet cure for a host of diseases because they can be transformed into nearly any cell in the body and used to help replace damaged or diseased cells, tissues and organs. However, stem cell research is highly controversial because, until recently viable human, embryos were destroyed in the process of extracting the most flexible stem. Stem Cell Research is due to the discovery due to science and technology developments. Japanese scientists found a way to use induce stem cells without triggering tumours.

     Scientists recently bypassed this problem by transforming human skin cells into stem cells. This offered the treatments tailored to the specific genetic code of a patient anything from blood transfusions to transplantable organs grown in a Petri dish without the need for harmful drugs to prevent rejection.


      But the skin cells were regressed using a method which caused tumours and for genetic mutation. Induced stem cells are safe for clinical use. Scientists have now managed to induce stem cells without causing tumours in a way which may not cause as much genetic ...
