Limited Exploration Of Human Stem Cells
Human stem cells consist of cellular formations that have not assumed a body function yet; they are present in embryonic tissues as a normal stage of development when more groups of specialized cells become 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 treating irrecoverable diseases such as Parkinson's disease, Alzheimer's, cancer, strokes, diabetes or heart attacks. With strenuous scientific efforts such progress becomes a reachable goal.
Human stem cells collected from embryos causes death to the donating embryo. 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 be converted into induced pluripotent stem cells instead of the embryonic ones. At the moment, views and opinions remain biased, which will continue as long as people see a real person in the fertilized union between a spermatozoon and an ovum.
Adult human stem cells are not subject to controversy but they somehow limit research because they don't have the same almost infinite potential of embryonic cells. In the mature form, stem cells can only develop into certain types of cells with definite tasks, 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, human stem cells could help to the creation of a panacea.
Although in the testing part goes great and, human stem cells perform well and make great promises, the clinical programs are far from being over. Some mysteries still escape scientific deciphering. For instance, we still don't know where adult human stem cells come from, even if things seem to be clear with embryonic research while adult stem cell studies are far from being over. Such an example is not at all singular, as there are many other blank spaces that science needs to fill before discovering the cure for all diseases and the fountain of youth.
