Stem cells are basically primitive cells that have the ability to build into specific cells and multiply. These cells are the source of all the tissues in the body and are therefore able to transform into any type of cell needed as components of an organism. whatever increase or development we experience, from belief to childhood to adulthood is the result of the development of stem cells.
The source of stem cells
A stem cell is created when an egg cell is fertilized by a sperm cell. This fertilized egg, called a zygote. At first the stem cell is unspecialized, meaning it is not yet a cell that can be considerable as cell that forms the muscles, bones or skin. It can later build to come to be separate cells like blood cells and bone cells.
What makes stem cells extra is that while every cell has the ability to divide and replicate themselves, only the stem cell can originate another cell type. The best source of these cells can be extracted from the tissues of a human fetus, which is today the source of controversy. When stem cells are harvested, the embryo will be destroyed and is therefore thought about by many as not a moral act.
One source of embryos for stem cells is the surplus from in vitro fertilization procedures. Many couples who have not been successful at conceiving donate a number of egg cells to a clinic to have them preserved for fertilization at a time to come time. Only one of these fertilized egg cells may be implanted in the woman's uterus. If everything goes right, the zygote will build into a baby.
The rest of the embryos that have not been used may be a source of stem cells. Since they are cells made from donors who no longer need them, scientists discontinue that they are no longer needed and could mean a lot of waste if thrown away.
Another source that have been in use for the past 40 years are adult stem cells, taken from the patient's body. Referred to as hematopoietic stem cells (Hscs), these cells have been used to treat medical problems such as lymphoma, leukemia and some blood disorders that are inherited. It also has the potential to treat diabetes and kidney cancer, except that studies made about the latter two are miniature and unreliable.
Praises and arguments
Stem cells hold a considerable promise in terms of medical those who have life-threatening diseases and disabilities. In theory, stem cells can furnish virtually any cell or tissue type there is in a human body to furnish an organ or a patch of skin to replace that which is defective or diseased.
In the case of adult stem cells, the quiz, of compatibility is done away with, since the cells are developed from the recipient's body. What he gets is genetically compatible with what he already has.
This potential could turn the way we live, improve our lives and maybe even prolong it. Stem cells will extend the limit to human life that nature imposed.
On the other hand, there are some nagging questions that face stem cell researchers and advocates, both medically and philosophically. Stem cells that could be controlled to build into a specific body part have yet to be isolated and produced.
There is also a quiz, about the genetic compatibility issues that stem cells raise. A recipient's body, for example, may reject the organ or body part that was grown out of a donor's stem cell. Stem cells, especially those that come from embryos are still in an animal testing stage and may still take some years before they are declared fit for use with humans.
The quiz, of ethics
Stem cells raise a few eyebrows and some protests from sectors that oppose the use of human embryos to promote research. This brings into life the decades-old argument of when human life nothing else but begins. Is it upon fertilization, while belief or after birth? Is a fertilized egg or a zygote, already a human being? How can a human embryo be sacrificed when it is already thought about good enough to be implanted in the mother's womb and later turn into a human baby?
There are also questions raised with regard to the ownership of the embryos, from which stem cells are extracted. Issues of ownership are brought into light in this instance and as yet, there is no clear delineation as to the ownership and responsibilities.
How about millions of stem cells from just a small group of embryos?
Currently, it is not yet clear to scientists how many embryos are needed to furnish the number of stem cells needed to build therapies or body parts. Some argue that one embryo would not be enough, since there could be a question with matching the donor cells with the receiver's genetic makeup. There is also a probability that one embryo might not have the right stem cells for every need for every one.
Other scientists also think that at some point, the harvest of stem cells could finally stop. However, there is no specific number of years for this -- it could go from two years or twenty or maybe 200 years, there is no assurance yet. All things considered, stem cell study is still in its early stages and it needs many more years in order to be a clear
Some sectors also believe that sacrificing one human embryo is the same thing as using hundreds or millions just for study or actual treatment. For them, one sacrificed fetus is one too many. It is also difficult to cut off the stem cell argument from abortion issues.
Should we fold?
Stem cell study potentially holds the answer to our quest for longer and best lives and could mean a time to come when disease and disability are no longer thought about problems. It also gives rise to definite ethical issues that make us face our humanity head on. Given our relative intelligence, have we yet to reach our potential or have we already gone too far? Should we ignore what human fetuses describe for the sake of the lives of the suffering? Do we dare to play God while trying to cure our humanity?
There are no easy answers. Only one thing is left for sure. Stem cell study will continue and so will advocacies for and against it. It has not come to it, but sooner or later. And although many feel we all might need to take sides, there is a clarification to this moral dilemma for us. Now there is a Patented Botanical extract that nothing else but has show in a triple blind study to increase your own adult stem cells up to 30% with each two capsules. This-sorry to get colloquial on you-sounds like a no brainer to me. The dilemma is gone...at least the one we had using embryonic stem cells. The dilemma now is that you might feel morally compelled to share StemEnhance with others.
