Stem Cell Research
Recently, there has been quite a lot of controversy among the media regarding the topic of stem cell research, its pros and cons, but what is this controversy really about? The term “stem” cells can be compared with another much known term: “differentiated” cells. The importance they bring to the humankind is that of the hope of new medical advancements being deposited into these cells because of their amazing capability to develop in almost any type of cell. For example, spinal cord cells that have been injured or neural cells in our brains that may have a certain type of disability would now be treated with these stem cells. Or, when talking about cancer, a disease that is nowadays affecting lots of people, especially

Of course, with such incredible news and many hopes put into this new technology, is not a surprise that millions of dollars are being separated exclusively for the means of stem cell research, something that our president Obama recently did, when he lifted the restrictions on federal funding for stem cell research, causing many people to praise his action.
In order to have a better idea about the issue of the pros and cons of stem cell research, we must first be aware of where does the stem cells come from. Basically, it’s been said that there exist three principal sources from where stem cells can be obtained, and they are embryonic cells, cord cells, and adult cells. Doctors can extract adult stem cells from two places: from the core of bones, or from the peripheral system. It has been demonstrated that the core of a bone is a plentiful source of stem cells, but the procedure of extracting those cells can result in a painful damage to the bone core. On the other hand, if someone does not want or cannot take that risk, there is the option of extracting the stem cells from the peripheral system, which can be done with no destruction of the bone, but that also takes more time to achieve it, and we all know that in presence of a health issue, time is a precious factor that cannot be delayed. Despite the fact that they are very hard to extract, the superiority of
