Stem cell breakthrough defuses debate

Scientists have discovered a new way to extract embryonic stem cells. They transformed human skin cells into stem cells that hold the same properties as the embryonic stem cells; thereby, defusing the controversy of destroying embryos. These cells can transform into all kinds of important tissues such as the heart, nerve and brain. This technique has been confirmed by experimenting on mice. Surprisingly, it was very simple, only four genes are needed to transform human somatic cells (skin cells) to stem cells. Stem cells are important in medicine because they can be used to cure degenerative diseases, grow new organs and even replace limbs. As a rule, every solution has some holes. This technique disrupts the molecular composition of the skin cells, that may enhance some chances of cancer. Despite that, I find this interesting because many stem cells were derived from embryos which sparks issue between religion and politics. Due to this new process, this has resolved the ethical issues and is good news for everyone. Medical problems can be solved without sacrificing human life.
