This paper focuses on the benefits of stem cell research in the medical and nursing field. New technology is always being created to help us understand the way the human body works, as well as ways to help us improve diseased states in the body. Our bodies have the ability to proliferate or regrow cells when damage is done to the cells. Take for example the skin, when an abrasion or puncture to the skin causes loss of our skin cells, the body has its own way of causing those cells to regrow. The liver, bone marrow, heart, brain, and muscle all have cells that are capable of differentiating into cells of that same type.
Since these cells are capable of differentiating into nearly all cell types, they serve as imperative research tools for the improved development of treatments and therapies for a vast number of diseases and conditions. Adult stem cells are undifferentiated cells, which are found throughout the human body after development. These cells multiply and divide in an effort to replenish any dying cells or damaged tissues in the body. These cells are multipotent, meaning they can differentiate into multiple, but limited cell types (Fritsch et al., 2008). Another type of stem cell that is of particular interest is induced pluripotent stem cells (iPS cells).
The world of science is developing very rapidly. This can be explained by the desire of people to know everything, e.g. the origins of life, the structure of human’s organism, the secrets of universe etc. The one of a set of branches in science is regenerative medicine, which includes stem cells research. Generally, stem cells are unique cells in the human’s body, which have an ability to renew themselves and become specialized into liver cells, kidney cells or spinal cord cells from unspecialized type of cells.
Adult stem cells have already shown potential to form cell types that might be useful in repairing organs. Stem cells from bone marrow have already been linked to curing diseases both in the immune and circulatory system. With their unique regenerative abili... ... middle of paper ... ...ns for the body. Stem cells have the uncanny ability to replenish dead cells and also repair worn organs. The hope for one day would be to perfect the technique of stem cell transfer without any chance of failure.
In the 19th century, stem cell research began to emerge in the labs of several scientists. It was discovered that stem cells could reproduce quickly and had the ability to produce other types of cells because they are unspecialized cells that are capable of changing themselves (“Journal of Stem Cell Research and Therapy”). In the early 1900s it was discovered that stem cells could be used to produce blood cells, liver cells, skin cells, tissues and several more. At first these stem cells were taken from bone marrow through a process called “bone marrow transplantation”, but it was soon discovered that these cells could also be obtained through peripheral blood, or blood take from the placenta, especially from cord blood. (“Immune Deficiency Foundation”).
Stem cells definitely have the ability to have a large impact in the science and medical fields. Science has grown so fast into finding new ways to treat a large number of different medical conditions and it is only a matter of time till these new findings are put into effect. The stem cells among us already have the ability to restore tissue and to also transform into different types of cells to fix diseases. The adult and embryonic cells are cells that scientists will continue to use to treat the many different diseases. Therefore, it is very important to know the basics of stem cells, the difference between the types of stem cells, and the possible uses of stem cells because science is moving quickly to have a promising future for those in need of medical help.

Please select your topic relating to some aspect of stem cell research or biotechnology or both. There are many things that make stem cells so unique. These characteristics gives them the potential to cure human diseases, because they are not specialized into becoming a certain cells yet, which allows them to be reprogrammed into whatever cell is needed. Also, there ability to regenerate and the usability brings scientists and researchers an endless supply of living cells, which can then be modeled and transported, to a worthy participant.
Another molecule of DNA that had also been snipped with the same restriction enzyme was found to have a corresponding sticky end that could combine with the original sticky end to form what scientists call a recombinant DNA molecule. By using restriction enzymes, scientists can cut genes out of chromosomes in order to reinsert them into other ... ... middle of paper ... ...eld of medicine. Both genetic engineering and stem cell technology are essential branches of biotechnology. Genetic engineering is the skillful manipulation of a gene by way of a process other than ordinary reproduction. Stem cells that won’t be denied by immune systems, can divide almost forever, and can alter themselves easily into other cells are used in stem cell technology and hold much promise in the cure of diseases and injuries.
The main focus of gene therapy is to replace a lost or improper gene with a new functional copy into a vector that is inserted into the subject’s genome by way of penetrating its DNA. Gene therapy can be done outside of the body known as ex vivo by way of taking cells form patients bone marrow or blood and then growing them in a laboratory. Thus the corrected copy of the gene is inserted into the cells before being put back into the body. Gene therapy can also be done in vivo which can be done directly to the patient’s body. The word gene therapy really defines the management of genetic information that is encased in the cells, however, in most recent procedures the available technology is closely related in adding new genetic information, and many researchers favor the term gene transfer rather than gene therapy to mirror the reason that the purpose of gene work cannot always be therapeutic.
One, to help contribute to the research to manufacture drugs to help the sickly, and two, to share in the profits of the quickly growing industry. Eventually, scientists will have figured out how to use stem cells from another donor, and not just of the diseased or injured person, to regenerate cells and/or muscle tissues. As an embryo is in its development stage inside of the womb, there are different chemicals that are exposed to the stem cells, which in turn “tell” the stem cells what type of neuron to be. Stem cells are the body’s master cells. They can renew themselves indefinitely and can even turn into any number of different types of cells needed in the body such as muscles, nerves, bones or even blood.
