My Blog Topic

I want to do research about the new breakthrough in stem-cell research. Recently, scientists have discovered a way to create stem cell without destroying and embryo. Before, scientists would take a fertilized egg and wait for it to develop into an embryo. Then, they would take stem cells out of the embryo, destroying the embryo. Now, scientists have found how to take skin cells and create stem cells. By adding four distinct genes to the stem cell, they can re-program it to be a stem cell.
