Stem cells dont need to come from an embryo?
Stem cells are cells that have the ability to become any cell type. They can develop into any of the organs and tissues that make up the body. In the past these cells were obtained from days old embryo’s but recently a team of Chinese scientists have shown it is possible to create stem cells from skin tissue. They have even gone as far as to take the stem cells they made from skin cells and reprogram them to look and act like embryonic stem cells which they then implanted in the womb of mice resulting in offspring. There are questions surrounding the potential drawbacks of such a birth. Will the offspring be prone to cancer?
