When the word stem cell, you may have heard of someone talking about it, or you may have read an article that discusses regarding its uses, but what are stem cells really and how are they taken?
Most of the cells in the human body are more on differentiated cells, and every human starts out as a single cell, fertilized, divide into different cells and differentiate to become a functional part of the body such as muscle cell or blood cell. Almost all of the cells that are present in the human body is more on what is called differentiated cells, and by basic a human originates from a cell, gets fertilized, divides into several cells and differentiate to become functional parts of the human body like the muscle cells. The so-called stem cells are cells that did not pass through the differentiation stage as yet, and these can regenerate multiple time to become another stem cell or as a differentiated cell.
Stem cells can be taken in two ways and this can be from a 2-5 day’s old embryo called embryonic stem cells, and the other is taken from a bone marrow and fatty tissues from a patient called the adult stem cells.
Stem cells are actually useful as per research in regenerative medicine for the purposes to repair or replace tissue or any organ function lost due to congenital defects, disease, damage, or age. The controversy that lies in stem cells is the argument in taking it from a human embryo which in essence many claimed to be a life being formed already and the with the taking of the stem cells such embryo will be wasted.
This issue has been a debated aspect especially by certain groups that also revolves in the aspect of ethical issues that result in the head to head argument between science and religion.
Another controversy that has been a concern for the use of stem cell is that there are clinics that are using it for treatments for some issues and even diseases with no known treatment as yet and without the appropriate research. Thus the real purpose here of stem cell research is put into question and the validity of proven treatments becomes inevitable because of the false or unverifiable claims made by these clinics.
Therefore, should you decide to consider to use stem cell for any treatment, you need to carefully identify the clinic that has the proven research and claim of what they car capable of compared to those ls reputable ones.
In the present time, continued research is still done to ensure full functionally of stem cell, and eradicate those controversies surrounding it, and once this research is gone wide, it will be the great future of regenerative medicine.
