Stem Cells Research Facts

Today's medication world has known stem cells therapy as a 'possible answer' to many diseases and disabilities. However, the stem cells research is rather complicated and has many controversial responses on it. That's why we need to know about the stem cells research facts.
Stem cell research pros and cons
What is stem cell? Stem cell is a kind of cell which can turn itself into any kinds of cell (specialized cells) with any functions, for example stem cells can be specialized into heart cells, lung cells, etc.. Stem cells are actually cells in their early development stage, so they have the potential to be themselves or to be other cells.

Why stem cells are very useful? Since stem cells have the ability to become other specialized cells, they can become the excellent 'spare part' for human body. In other words, their job is to replace the role of any damaged cells. When the damaged cells in an organ are replaced with the new ones, the organ can work normally again.
Until now, stem cells research facts conclude that the stem cells therapy is able to cure Multiple Sclerosis, Parkinson, Alzheimer, heart diseases, stroke, arthritis, diabetes, burns and spinal cord injury.

Generally, the process of stem cells therapy includes these three steps :
1. Extract the blood stem cells from patient and froze it.
2. Decrease the immune cells in patient's body.
3. Implant the stem cells back into patient's body.

The different facts of embryonic and adult stem cells

1. Embryonic stem cells are believed to be more flexible in specialization than the adult stem cells although the adult stem cells are still very 'moldable'.
2. Embryonic stem cells are easy to be grown in laboratory while the adult stem cells are rather difficult because they are lack of mature tissues.
3. Embryonic stem cells are very small, only a microscopic-ball size. And they are put back into patients' body after 4-5 breeding days (still very young).
4. Embryonic stem cells are however an embryo which will grow up to become a complete human being. Therefore the experiment on embryonic stem cells may be morally or ethically wrong.
5. Because the stem cells are frozen or grown outside the human body, it is afraid that the stem cells may have viruses and not safe to be transplanted back into human body.
6. Stem cells are bred through animals' nutrients. Therefore they may contain diseases.
7. Some researches state that there is a possibility of stem cells turn into cancer cells.
