Limited Research Of Human Stem Cells
Human stem cells consist of cellular formations without a determined body function; they first grow in embryonic tissues when the body is developing, and new groups of specialized cells are necessary, but they happen to be part of adult tissues as well. No recovery from disease, injury or decay would be possible without these human stem cells that activate the moment they are needed. Human stem cells now represent the medical hope for the treatment of irrecoverable diseases such as Parkinson’s disease, Alzheimer’s, cancer, strokes, diabetes or heart attacks. And if science makes enough progress such achievements will be possible.
Most of the research conducted on human stem cells has used biological material taken from human embryos that would get killed in the process. Since this practice caused lots of controversies and debates, it was banned for almost eight years in the United States. Presently, efforts are being made to develop a technique that would enable skin cells to transform into induced pluripotent stem cells instead of the embryonic ones. At the moment, opinions and views still have a bias, as many people tend to see a real human person in the fertilized encounter between an ovum and a spermatozoon.
Adult human stem cells are safe from the moral controversy but they are definitely limited in terms of research capacities. In the mature form, stem cells can only specialize as certain types of cells with definite functions, and therefore, the potential is not unlimited as it seems to be the case with embryonic human stem cells. The choice could be pretty difficult if we consider the ethical point of view: can we stop a fetus from growing for pure scientific reasons? And on the other hand, the other part of the controversy is the creation of panacea by such sacrifices.
Although in tests, human stem cells perform well and make great promises, the clinical programs are far from being over. There are still lots of mysteries to unravel and things to understand. For instance, the origin of the adult human stem cells is not known at the moment, and, while things seem to be clear with embryonic research while adult stem cell studies are far from being over. This is not the only example, as there are many other blank spaces that science needs to fill before discovering the cure for all diseases and the fountain of youth.
