Why stem cells are important?

Stem cells treatment has been used over a decade and proves to be the best cure for many chronic diseases such as diabetes, spinal cord injury, burns, heart diseases, Alzheimer, Parkinson, cancers, etc.. Some of the treatments are successfully done on humans, and some are only successfully tested on animals. And stem cells treatment may have the potential to cure more diseases in the future.
The miraculous abilities of stem cells have shown why stem cells are important, and why studies and researches are largely made for them. In other words, the scientists believe that stem cells have unlimited ability to cure diseases.
To deeply understand why stem cells are important, let's start from the nature of stem cells.

There are three unique natures of stem cells that do not exist on other cells, such as:
1. Self-reproduction ability. Stem cells can duplicate itself by cell-division (one becomes two, two become four, etc.)
2. Neutral. Stem cells are the earliest stage of cells which haven't had any specific functions.
3. Can be specialized. Stem cells can be specialized into many types of cells (heart cells, lung cells, pancreas cells, blood cells, etc.)

The importance of stem cells in many health cases

Stem cells have many important roles in medical world. Check this out and you'll understand why stem cells are so important.

1. Support the basic human development.

The study of stem cells is actually the study of human development, starts from the embryo, the fetus, the development of tissues, nerves, heart, blood cells until the perfect human. In this study, scientists learn about cells differentiation and proliferation which are important to identify any cells mutation that leads to cancer or other diseases, and find the best way to prevent or even cure the situation.
2. Disabilities from birth

Many children are born with physical disabilities. The study of cells differentiation and proliferation may find out the causes of the situation. It may happen because of the cells division defects, cells mutation, or even chemical drugs. Through this study, the scientists have more chances in finding out the causes and find the best way / drug to prevent or cure it.
3. Cell replacement

As we know that stem cells have the ability to be specialized into many types of cells, then they can replace any damaged cells and tissues. Cell replacement is the most common stem cells therapy done for decades to cure diabetes, heart diseases, and some cancers.
4. Revive the organs

Stem cells are 'brilliant' cells. When transplanted into human body, they can track the damaged area and focus on the treatment there. They replace the damaged cells and revive the sick organ. When the organ is healthy, it can produce more healthy cells and works normal again. This is very important since many patients have waited so long for organ donors, and still do not get any until the day they die. With stem cells treatment, these patients' organs can be revived and they won't need any organ donors anymore. It certainly saves many lives.
5. Body-immune friendly

Human body immune system always attacks the alien objects that enter the body. But the transplanted stem cells do not trigger the immune system awareness because they are actually taken from the same patient. That's why stem cells treatment is body-immune friendly.
Actually the main point of why stem cells are so important is that they can save many lives. This is a guarantee that other treatments do not offer. However, further researches are needed to find out more about stem cells' abilities, and to create best drugs for many diseases.
