Scientists succeeded and transform cell indetity by Milota Sidorova

Scientists at the University of Pennsylvania made a huge progress in so called cell biology in recent days. They succeeded and tricked an identity of human cells. Literally, they made a skin cell to transform into embryonic stem cell and for those who don't understand what does that mean it can be translated like this. If you change the form and function of specialized cell, for instance blood cell or skin cell, it can work like any other cell – for example cell that would be needed. This could lead into internal organ reparations and surgery without knives and operations. But the current state is far from this vision. Scientists have succeeded in changing a human sk! in cell into the embryonic stem cell what is the name for immature universal cell that can modify into any type of a cell. Experiments have succeeded in this direction in 2007, but the direct transformation from one type of specialized cell into another wasn't working. Research team suggested they were far from safe utilization of this experiment and their research method was trial-and-error which is the most inefficient method in the science, because it is energy, material and time consuming. Scientists are using chemicals to speed up certain genes – all cells contain the same DNA information, but each cell is using its own genes, so if one wants to create a different cell, different genes have to be awaken. These experiments are not safe and people and mouses are used. Scientists also can't specify consequences of such tricked cell – whether it is going to maintain its new characteristics, whether it is going to survive and multiply with no potential harm (me! ans cancer cell behavior). Despite such grave obstacles, there! is no d oubts it is a huge step that may change our view on human beings and medicine.
