Adult Stem Cell Cures

Stem cells: science, benefits, debate, and the future

Although Obama has recently lifted the ban on federal funding for research on embryonic stem cell research imposed by President Bush eight years ago, some people still oppose this initiative and ethics call. So while the scientific community is thrilled by the news and said that medical research will progress Some communities consider research as a "slippery slope." But what exactly are the stem cells and why they are so important to encourage debate between all kinds of hot circles – political, social, religious, and not what? Here is a summary of some of these details.

The science behind Stem Cells
What distinguishes stem cells from other cells is also their ability to transform into any other tissue in the body. A stem cell bone marrow, for example, can become a neuron or a nerve in the brain.

Types of stem cells: embryonic stem cells compared with adult stem cells
In general, there are two types of human stem cells – embryonic stem cells and not embryonic stem cells. Cells embryonic stem (CES), as its name suggests, are isolated from the inner cell mass of an early embryo (4-5 days after fertilization, and composed 50-150 cells). On the other hand, non-embryonic stem cells which are also called adult stem cells found in adult tissues.
Cells Embryonic stem cells are pluripotent, unlike adult stem cells are multipotent. This means that embryonic stem cells can differentiate a total of over than 220 cell types in the body of an adult (to give rise to any mature cell type), while adult stem cells can form a limited number cell types (close to the family of cells).

Utility of stem cells
The importance of stem cells lies in the fact that they can become any type of cell or tissue in the body – neurons, pancreatic tissue, heart muscle cells, etc.
For example, cells bone marrow stem possibly be used to repair heart muscle damage caused during a heart attack, or to correct blood disorders like sickle cell anemia (anemia) by transfusions of stem cells.
stem cell therapy is believed that the potential to radically change treatment of human diseases. Embryonic stem cell therapies (ES) have been proposed for regenerative medicine and tissue replacement after injury or illness.
But it should be noted here that the embryonic stem cell therapies are not yet used. They are still at the stage where researchers Doctors are testing on animals.
On the other hand, adult stem cells have been used successfully to treat leukemia (leukemia) and bone associates blood cancer using bone marrow transplants.

Controversy
The controversy behind stem cell research covers only embryonic stem cells and not any research on stem cells. What is controversial is the fact that the starting material for research, human embryos are destroyed in the process to harvest stem cells. The pro-life activists oppose the research, arguing that the human embryo is a life human is entitled to protection.
Another contentious issue is that embryonic stem cell technologies are a slippery slope that could lead to cloning reproductive, which can devalue human life.
The production of adult stem cells, however, does not require the destruction of an embryo and, consequently, Adult stem cells research and therapy are not as controversial. Although adult stem cell treatment does not involve a risk of rejection by the immune system organization.

The current state of research on stem cells
There are countries that offer stem cell treatments (see medical tourism) but these therapies are not adult stem cells from the patient are used (autograft). Whenever possible, autografts are preferred because they eliminate the risk of rejection by the recipient's body.
Promising research underway in the field of stem cells to treat a wide variety of diseases including cancer, Parkinson's disease, spinal cord injuries, diabetes, heart disease, Alzheimer's disease, amyotrophic lateral sclerosis or ALS (Lou Gehrig's disease), multiple sclerosis, lung disease, arthritis, organ failure and muscle damage, amongst a number of deficiencies and conditions.

The future
The last question in the mind long is – "Why can not we just use adult stem cells instead of harvesting embryonic stem cells?
Theoretically, embryonic stem cells are considered better, as they act as a blank slate and biologically the most versatile of all cells mother while adult stem cells are a kind of semi-skilled and cells are not as versatile as ESCs.
Although the field of adult stem cells is not affected by the dispute, the problem with adult stem cells is often present only in minute quantities, are difficult to isolate and purify, and their number may decrease with age, according to a booklet by the National Institutes of Health (NIH).
At this stage it is still much to learn about the potential embryonic stem cells. However, through success in the field of animal experimentation, may well be that embryonic stem cells could offer solutions to many diseases in humans.
The response to the CES potential benefits in research. To understand the benefits of stem cells embryos or other stem cell types for this problem and to find a cure possible in humans, different lines of research to be pursued simultaneously.
Only research can test whether adult stem cells are better in embryonic stem cells to cure diseases in humans or vice versa. You can also emerge as adult stem cells are good treatments for certain diseases, while embryonic stem cells are better for healing others.
