Imagine a treatment that helps a grandmother weakened by heart failure regain her independence. Imagine damaged organs regenerating and wounds healing without leaving scars. Imagine a child desperate for an organ transplant that can now smile again because he has a liver. Regenerative medicine is a relatively new approach to treating injuries and diseases; it utilizes specially-grown tissues and cells (including stem cells), laboratory-made compounds, and artificial organs. Variations of these methods can intensify the healing process in the areas its needed most, or take over the role of a permanently damaged organ. Furthermore, regenerative medicine is a new field that brings together experts in biology, chemistry, computer science, engineering, genetics, medicine, robotics, and other fields to tackle challenging medical problems faced by humankind. Importantly, regenerative medicine has the prospective to solve the problem of the shortage of organs available for donation compared to the number of patients that require life-saving organ transplantation, as well as solve the problem of organ transplant rejection, since the organ's cells will match that of the patient. Strategies presently under development include transplants of stem cells, the manipulation of the patient's own stem cells, and the use of scaffold materials that emit biochemical signals to spur stem cells into action.
It sounds like an effective solution, but how successful is this process? How long have scientists spent researching and developing this? The study of stem cell implementation in regenerative medicine has been pioneered by many researchers over the past 10 years, but methods are still being perfected and long term effects are still unknown to scien...

...r the patient could possibly contain hidden malignant diseases within that tissue. Ethical issues pertaining to the implementation of these artificially synthesized organs also pose a threat.
Personally, if I was placed in the shoes of a patient in desperate need of an organ, I would be willing to forerunner this new type of technology. Although there are many risk factors to be considered, it is undeniable that bio-artificial organs are an efficient substitute for donated organs. Perhaps receiving an organ synthesized by an individuals’ own cells would not be such a bad solution. Optimistically, techniques for regenerative medicine will come to market within ten years. Bioengineered organs have the potential to reduce the need for live donor organs, allow more deceased donor organs to be used rather than discarded, and shorten the waiting list for transplants.
Personal Credibility: I have always held a curiosity about the anatomy and physiology of the body and all the parts that work together to keep us alive. Equally, it is extraordinary that medical advances have made it possible to undergo surgery to replace a failing organ with a thriving new organ, further saving a life. According to the United Network for Organ Sharing statistics: Every 10 minutes another name is added to the national organ transplant waiting list. At one point in your life, you will know someone who needs a transplant.
“Through the isolation and manipulation of cells, scientists are finding ways to identify young, regenerating ones that can be used to replace damaged of dead cells in diseased organs. This therapy is similar to the process of organ transplant, only the treatment consists of the transplantation of cells rather than organs. The cells that have shown by far the most promise of supplying diseased organs with healthy cells are called stem cells.” (Chapter Preface)
Because stem cells are essentially a blank slate, scientists are theoretically capable of growing any human tissue cell. There is enormous medical potential in this. Stem cell research is the next step in advancing the medical field. It is comparable to the discovery of penicillin or the inoculation for smallpox.
Imagine that there is a cure for nearly every ailment that affects the human race. Imagine that you could help the terminally ill, put those you love out of pain, and cut the healing time of an enormous number of serious illnesses in half. Imagine a world in which pain and suffering would be nearly nonexistent, and the people you love can live safe from the fear of crippling injury. Now what if I told you that this utopia was a fast approaching reality? Everything from serious life threatening burns to lymphoma, AIDS, Alzheimer’s, Muscular Dystrophy, Parkinson’s Disease, Spinal Cord Injury, and Strokes could, in the very near future, be eliminated through the simple culturing and implementation of stem cell therapy . These diseases are no small component of the myriad of conditions that plagues the human race, and yet, the end for these horrible maladies could very well be in sight. Man has always sought to end suffering, largely without success, until now. the promise that stem cell therapy holds could completely change our world for the better. Already, stem cell therapy is being used to treat leukemia, immune disorders, hodgkins and non-hodgkins lymphoma, anemia and a profusion of other ailments. As you all know, this is no small accomplishment. One day i believe that we may look at alzheimer's and diabetes and other major illnesses much like we look at polio today, as a treatable illness. Right now, our research with stem cells is providing us with new light into how we look at and model disease, our ability to understand why we get sick and even to develop new drugs. In 2008, a researcher from the New York Stem Cell Foundation Laborato...
The human body; it starts off as a single cell, and grows into a complex machine made of seventy eight distinct organs, two hundred and six bones, and millions of nerves that all communicate with each other to regulate body processes and keep the machine alive and healthy. This seemingly perfect system undergoes countless attacks every day, and manages to recover from most, although occasionally, it can not. Diseases such as Cystic Fibrosis and Coronary Artery Disease, or abnormalities and defects such as biliary atresia, can all disrupt the function of human organs (“Transplant Australia”, n.d ). Thankfully, through radical advancements in modern medicine, organ transplants are a safe and highly viable option to restore the human body’s perfect harmony. No matter the reason for organ failure, once it occurs, the patient’s journey to receiving a new organ begins. Through the matching of organs, the process and the complications that come with it, the ethical issues, and trials of new advancements, the journey is a long one.
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. These are called stem cells, and are a new medical tool that is helping regrow vital organs in our body to help us survive. Stem cells can come from adult cells, or the blastocyst of the embryo. The cells that come from these are undifferentiated, and can be specialized into certain cell types, making them available for many damaged tissues in the body. While using stem cells in the body is a main use, they are also being used to help doctors understand how disease processes start. By culturing these cells in the lab and watching them develop into muscles, nerve cells, or other tissues, researchers are able to see how diseases affect these cells and possibly discover ways to correct these diseases. While researchers have come very far in using stem cells, there are still many controversies to overcome when using these cells.

The issue brought before us today is whether the commercialization of organ transplants is both ethical and beneficial to the economy and populace as a whole. There are many issues which are centered on this decision on which I hope to shed some light and allow for better resolutions to be made. In nearly every country in the world, there is a shortage of kidneys for transplantation. According to Corydon Ireland, in the United States 73,000 people are on waiting lists to receive a kidney. About 4,000 can pass away every year before receive a lifesaving organ. (Corydon Ireland, Harvard News Office. February 14, 2008) Some of the benefits of organ commercialization are increased revenues and jobs, as it would open a whole new arena of business, more widely available organs to those in need, and a wider method by which under-performing citizens can create temporary cash flow. There are many arguments against the allowance of organ commercialization, they include the fact that many consider it unethical to sell body parts, concern over the safety of these procedures, and doubt as to how those who donate will be treated medically post-sale. The final, separate issue which would need to be addressed is how health insurance companies are to handle those who sell organs and any post-op health issues that relate to the sale.
Stem cells are located deep down in our bone marrow. They have the incredible ability of “generating an endless supply of red cells, white cells, and platelets”(1). They have been called the “Mother of all blood cells” due to their ability to regenerate the entire blood supply of a persons body. Just to think that this is possible is actually pretty incredible. The man who claims to be responsible for the discovery of this gem is a immunologist from Stanford University named Irving Weissman, and his collaborators at SyStemix, (a biotech company that he cofounded in 1988, located in Palo Alto, CA). He and his company are so confident about these cells, not only have they obtained a government patent on the process by which these specific cells are separated from other cells, they have also patented the cells themselves. They have even convinced Sandoz Ltd. (a giant Swiss drug-and-chemical company) to purchase 60 percent of the stock for SyStemix for a reported 392 million dollars.

Stem cell research is not necessarily bad and this research can lead to a positive breakthrough in the medical field. Researchers and consumers have a mutual interest in distinguishing the good research from the bad.
In order to discover the ways for the remedy of diseases, studies in therapeutic approaches have been doing widely and kept increasing at accelerated pace. A lot of research areas had emerged for that purpose including one of the most fascinating and highly active areas at present, stem cells therapies. Due to self-renewal property and differentiation capability of stem cell, it becomes a new hope in modern treatment.
The field of regenerative medicine encompasses numerous strategies, including the use of materials and de novo generated cells, as well as various combinations thereof, to take the place of missing tissue, effectively replacing it both structurally and functionally, or to contribute to tissue healing[29]
These procedures hold infinite possibilities in the practice of healing the sick. Of all of the procedures mentioned, cloning is the only method that has been given any amount of serious research. Cloning could do away with the need for organ transplants. Instead of a transplant, a new organ could be cloned, thus removing any chance that the body might reject the organs. Nano-robotics can be used to fight off foreign infections and repair internal wounds.
