Stem cell transplants are often one of the last choices a patient has to survive cancer. All have already gone through chemotherapy, radiation therapy or both and this is the next step in their treatment. Patients have two choices in transplants autologous or allogeneic. In an autologous transplant stem cells are collected from the patient and then given back to them at a later date after the body has been properly prepared for transplantation. In an allogeneic transplant stem cells are collected from a donor, related or unrelated to the patient, then transplanted into the patient. Stem cells can be collected in two different ways. One way is via bone marrow and the other is via peripheral blood. The donor’s or patient’s bone marrow is collected from the pelvis, femur or sternum, though the pelvis is the most common, and then infused into the patient via a central line. In a peripheral blood stem cell collection the donor or the patient has their stem cells collected via a central line in a process called apheresis. This can take multiple collections to ensure enough stem cells for transplantation. Both procedures need to be meticulously planned and all support medications given to ensure successful collection. There are many cancers that stem cell transplants are commonly used for. Multiple myeloma, acute lymphoblastic leukemia, Hodgkin’s disease and chronic myelogenous leukemia are more commonly treated with transplantation. Each of these cancers has a different success rate, some have a higher success rates than with chemotherapy alone. Proper preparation is important for stem cell transplants. All patients undergo chemotherapy…...

...STEM CELLS Science has made many discoveries over the years and its discoveries have helped us understand why things happen and why they happen. We have had many great scientists who devoted their lives in laboratories testing many natural and chemical reactions. Medicine is a field in which over the years science has made a lot of improvements and many scientific tests helped us found the cure of many deadly deceases. Even though there has been a lot done there is still a lot more to be accomplished. In 1981 scientists started testing one of the most amazing discoveries of medicine, Stem Cells. Stem Cells are cells that have the potential to develop into many different types of cell in the body during early life and growth. These serve as a repair system by dividing themselves without any limits to replace other cells, such as muscle cells, red blood cells and brain cells. One of the most potential uses of human Stem Cells would be to replace the necessity of organ donation, which nowadays the demand is very high. These cells can replace specific cells type and renew tissue to help cure Alzheimer’s decease, spinal cord injury, stroke, burns, heart decease, diabetes, osteoarthritis, and rheumatoid arthritis. One good example is to generate healthy heart muscle cells in a laboratory then transplant the cells into a patient with a heart decease. Type 1 diabetes is another serious condition, which many people suffer specially in this country. New......

...Stem cell research has become one of the most controversial topics next to abortion. Scientist, Researchers, and some medical professionals feel we are loosing precious time with the political, legal and ethical aspect of this topic and should focus more on how modern medicine can be improved and where stem cell research could take us in the future. Stem cell history began in the 1800’s both human and animal stem cells were used. Scientist fertilize egg cells through the vitro process, this was the most successful way to cause reproduction in a human egg, but with more advance research and tools the possibilities could be endless. Stem cell are classified into three categories; Totipotent, which are found in early embryos, pluripotent exist in the inner cell mass and can from over 200 cell types in the human body, and multipotent that are derived from fetal tissue, cord blood and adult stem cells. Multipotent stem cells are more commonly used in cell-based therapies because they have the best success rate. In the 1900’s the first application of stem cell research was bone marrow transplants using adult stem cells. Bone marrow was given to patients orally that had anemia and leukemia, this was proven to be ineffective way to administer and treat the illness. Treatment was only proven to be successful when given through the blood stream from a compatible donor. In 1984 Congress passed the National Organ Transplant Act this led to an increase of people in the bone......

...Stem cell A stem cell is essentially a “blank” cell, capable of becoming another more differentiated cell type in the body, such as a skin cell, a muscle cell, or a nerve cell. Microscopic in size, stem cells are big news in medical and science circles because they can be used to replace or even heal damaged tissues and cells in the body. They can serve as a built-in repair system for the human body, replenishing other cells as long as a person is still alive. Adult stem cells are a “natural” solution. They naturally exist in our bodies, and they provide a natural repair mechanism for many tissues of our bodies. They belong in the microenvironment of an adult body, while embryonic stem cells belong in the microenvironment of the early embryo, not in an adult body, where they tend to cause tumors and immune system reactions. Most importantly, adult stem cells have already been successfully used in human therapies for many years. As of this moment, no therapies in humans have ever been successfully carried out using embryonic stem cells. New therapies using adult type stem cells, on the other hand, are being developed all the time.  Significance of the Study Stem cell therapy is a potential treatment for spinal cord injury and different stem cell types has been grafted into animal models and humans suffering from spinal trauma. Due to inconsistent results, it is still an important and clinically relevant question which stem cell type will prove to be therapeutically......

..."Embryonic stem cells...are in effect, a human self-repair kit," (Christopher Reeve, activist – Larry King show). For the advancement of science, stem cells are infinitely valuable, especially when considering all the potential applications in the field of medicine. Stem cells usage is a very controversial topic, because most people think of abortions, cloning, and other negative topics when they here the term stem cells. However I think those thoughts are because they don't understand what a stem cell is, where it comes from, or its monumental possibilities that could greatly benefit the medical field. In today’s medical world there is so much that can be done with stem cells whether it is generating new organs or saving an individual with terminal disease? There are already demonstrations of Stem cells possibilities, because treatment with stem cells has already begun. They have been taken from umbilical cords and become healthy red cells used to cure sickle-cell anemia. Stem cell therapy is also being used against certain types of cancer. Stem Cells are valuable due to the fact that they are non-designated and they have the ability to divide and multiply indefinitely. Thus, theoretically stem cells could fix and even replace any damaged or lost specific cells within a body. They are easily found in early embryos, but their numbers variety for development seems to become less in the adult stem cells. The information above is only what we know right now, but that's just......

...STEM CELL RESEARCH AND THERAPYAND ITS IMPACTS ON SOCIETY Abstract There are several types of stem cells being used in stem cell research and therapy today. They are embryonic, adult and induced pluripotent stem cells. Each will be discussed further. This topic has stirred much moral, ethical and political debate as whether cells from fetuses should be used in this research. This impacts governmental policies on laws and funding. Another issue that must be analyzed is the economics and who should have access to this treatment. The views of people and government on this research differ greatly across the world. There are countries that have very strict laws restricting this research while others take an extremely liberal stance. Stem Cell Research and Therapy and Its Impacts on Society Introduction Stem cells are the basic unit of life that gives rise to all living things. They are the undifferentiated cells that transform into the specialized cells that make up all of the tissues in organisms. With further research and understating, these cells can be used in medicine to cure a wide range of diseases. The most important type of stem cell to humans is the pluripotent stem cell which is usually obtained from human embryos. This has sparked controversy in many aspects of human life. In this paper, we will concentrate on animal and human stem cell research, and its impact on society. A Brief Description Of The Technology And An Explanation Of The......

...form of Stem Cells Dear John, After our brief discussion regarding the Doctors suggestion for stem cell therapy, I quickly began to gather information surrounding the topic to aid in your decision making. Stem cells have been researched for over thirty years. Primarily two types of stem cells have been used for research, from both humans and animals, entitled embryonic and non-embryonic cells (Stem cell basics, 2002). The research for embryonic cells came in the early eighties after mice embryos had been used for extensive research. It was found that human embryonic embryos can be utilized as stem cells and reprogrammed to adapt in order to become the desired type of cell needed. Do you remember when my wife and I endured our round of in-vitro fertilization to conceive our first child? The fertility specialist was able to gather 13 embryos during egg retrieval. All 13 embryos were successfully fertilized. After forty-eight hours it was determined that only 8 had divided in a healthy manner and were able to continue the process of maturation (splitting). Four were then frozen using cryonization and the other four were left to continue onwards to blastyocysts. Two of the four did not make it past 36 hours however two of them developed into grade “A” cells allowing for implantation. We were fortunate that one of the two cells implanted and resulted in a healthy pregnancy. I share this story with you to illustrate how delicate the process of obtaining healthy stem......

Stem Cells

...INTRODUCTION Stem cells have the unique ability to differentiate into any cell in the body, which has made them a central focus for regenerative cell therapy for a vast number of human diseases ranging from cardiovascular to neurodegenerative disorders. A major example for the use of stem cell therapy is Parkinson’s disease (PD). Pharmacological treatments for PD have been developed; however, neuronal degeneration prevents these drugs from working for extended periods of time. Stem cell therapy does have the potential for providing a permanent treatment for this disorder. In order for stem cell therapy to be effective and safe, the stem cells must be at a certain differentiation state, which is currently defined by a combination of surface markers, prior to implantation. One major obstacle preventing translation of stem cell therapy into a clinical setting is the inability to determine and isolate stem cells at particular differentiation states. In the case of PD, the optimal stem cell for transplantation would be a dopaminergic neuroblast which is differentiated enough to allow neural integration thereby reversing disease progression. Additionally, optimal differentiation will prevent tumor formation resulting from an overly immature stem cell (Wernig et al, 2008). Thus, there is an urgent need to identify and track the differentiation state of cells in order to realize therapeutic potential. Our long term goal is to identify and purify appropriately differentiated stem......

...Stem Cell Research Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell. Different types of stem cells Embryonic stem cells - These stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs, although their use in people has been to date limited to eye-related disorders such as macular degeneration. Adult stem cells - These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body. Until recently, researchers thought adult stem cells could create only similar types of cells. For instance, researchers thought that stem cells residing in the bone marrow could give......

...English 102 Stem Cells: There are 3 main types of stem cells- embryonic, adult, and induced pluripotent, that provide great advances to modern medicine (Power). In recent years, the discussion of stem cells has become that of a political and moral debate. There are many misconceptions about stem cell research. The advantages far outweigh the disadvantages. “Stem cells promise great advances in the treatment of injury and disease, but many problems must be overcome before their potential can be realized.”(qtd. in Power) Before an opinion can be developed on if stem cells should be used, one must know what and how they are used. Stem cells have caught the eye of scientists since the early 1800‘s where cell propagation and differentiation were witnessed for the first time. It was a Russian histologist named Alexander Maksimov who, in 1908, first put forward the existence of the stem cell (and coming up with the term himself) as part of his theory of hematopoiesis (What). According to Maksimov’s hypothesis, all cellular blood components were derived from hematopoietic stem cells(What.). However, there had been no major developments in the field of stem cell research for some 60 years after Maksimov’s theory was proposed In the early 1900‘s European researchers made the discovery that all blood cells and platelets came from a specific ‘stem cell’(What.). However it was not until later in 1963 that the first quantitative......

...discovery of stem cell therapy, it has been a controversial topic of long debate of moral ethics and politically. The discovery of stem cells and their ability to generate new cells began in the 1800’s. Today the topic of research therapy makes headlines with its controversy with the use of embryonic stem cells. Historically stem cell research includes plant, animals and human stem cells but today the prominent use of stem cells in humans is bone marrow transplant. This has become a simple one day medical procedure that is one of a lesser debate. Complete strangers can now simply be tested for a compatible match to an awaiting recipient. This type of success has brought stem cell to the forefront of medical researches discovery of other stem cell therapies that are futuristic in nature and have the possible to cure devastating disease and injuries that would otherwise leave someone completely debilitated or worse. Stem cell therapy is on the verge of being a revolutionary medical advancement in history. The discovery that stem cells could generate new healthy cells in the 1800’s had revolutionized the medical profession. Blood marrow transplant are the front runner of the success that stem cells can produce. This is the prominent force that guides researcher to believe that stem cells can be a cure for many diseases such as Parkinson’s disease, immune deficiency disease, certain types of leukemia’s, severe blood disorders and traumatic injuries to the spine and brain.

...Comp1 Stem Cells Research Paper Stem Cell Research Paper Since their discovery, the ethics of human embryonic stem cells have been debated. As the ongoing controversy over human embryonic stem cells persists, we continue to look for alternative means of acquiring similar task-performing cells. Margaret Goodell was one of the first to propose extracting stem cells from other sources, most notably bone marrow. Without the ethics baggage, bone marrow derived cells seemed to put aborted fetuses out of the picture. Yet, according to Catherine Verfaillie of the University of Minnesota, bone marrow cells with the same ability as stem cells are very rare. She estimates that perhaps only one out of ten billion marrow cells are versatile enough to have the ability to adapt into other functioning cells. Although this could be done, the process of finding these cells makes it difficult. Bone marrow “stem” cells, if you will, have no molecular marker that differentiates them from other bone marrow cells. The only way to recognize the difference between them is by a process of tests, which makes finding them excruciatingly difficult. They are more common in younger children, however, they have been found in some donors who were in their late forties and fifties. Verrfaillie believes this to be attributed to the development stages in youth. Besides the ethical point, adult cells are easier to manage, according to Verfaille. They are more responsive to the environment they......

Stem Cell and Cell Culture

...STEM CELL & CELL CULTURE Differences between embryonic and adult stem cells. One of the differences between embryonic and adult stem cells is the cell potency. Cell potency comes from the term potential and basically means a cells’ potential to differentiate and take on different functions. Embryonic stem cells are pluripotent and thus can form all types of cells (endoderm, mesoderm, and ectoderm). Adult stem cells on the other hand are mostly multipotent, meaning the cells can only differentiate to different cell types from the same tissue of origin. For instance, blood stem cells can differentiate into many different type of blood cells but cannot differentiate to become muscle or neuron cells. To put it simply, adult stem cell are more specialized (focused on a particular tissue lineage) whereas, embryonic stem cells are more versatile. (Stem Cell Research- Pros and Cons, Date retrieved: 17th September 2011) Another difference between adult stem cells and embryonic stem cells is the ease of culturing these cells. It is significantly easier to cultivate embryonic stem cells in comparison to adult stem cells. Adult stem cells are hard to isolate in mature tissue and have a hard time surviving past a few generations during the in-vitro culturing. Considering stem cell therapy requires a large amount cells, embryonic stem cells are a more feasible alternative as they can grow rather easily in the lab.

...Stem Cells Since being discovered, the ethics of studying stem cells for medicine has been debated. As the continuing controversy over this research continues, the funding for it diminishes, and thousands of lives that could've been saved slip away. Embryonic stem cell research, which has the potential to serve the medical field in countless ways, will remain stagnant until we as Americans realize that it can be the key to most of today's deadliest diseases and injuries. Margaret Goodell, a professor at the Baylor College of Medicine, was one of the first to suggest extracting stem cells from other sources, most notably bone marrow. Without people being able to use the ethics card, bone marrow derived cells seemed to put aborted fetuses out of the picture. But, according to Catherine Verfaillie of the University of Minnesota, bone marrow cells with the same ability as stem cells are very rare (Snow 48). Verfaillie estimates that only one out of ten billion bone marrow cells are versatile enough and have the ability to adapt into other working cells. Even though these cells would work, the process of finding them makes it difficult. Bone marrow “stem” cells, if you will, have no molecular marker that differentiates them from other bone marrow cell. (Snow 48). The only way to see the difference between them is by a long process of tests, which makes finding them incredibly difficult. They are more common in younger children, however, they have been found in some adult......

...Embryonic Stem Cells Embryonic Stem Cell Research A man in a motorized wheelchair makes his way down the sidewalk toward me. Bags of groceries hang from the handles and any other protrusion that can serve as a hook. He is accompanied by an older woman who walks behind him; one hand gripping her own load of bags while the other rests lightly on the back of the chair. They stop once they are near me and I get a clear look at the occupant of the chair. He is a young a man. Thin, emaciated arms and legs are drawn in toward his body. It is clear that he has been confined to this chair for a long time. The woman is his mother and she asks me if I can watch him while she goes into a nearby building to call a friend to give them a ride. I agree and she leaves me with her son. I strike up a casual conversation, looking him in the eye and being careful not to talk down to him. His speech is labored and slurred. He is suffering from cerebral palsy. His mother returns and thanks me; her friend is his way to help. I go about my business realizing that I have no problems in my life when compared to that young man. My body is sound. Imagine being trapped in your body like that. Then realize that there is a real potential for a cure, but no one is allowed to work on it. Embryonic stem cell research has the potential to cure that young man and thousands like him. Perhaps it is time to we lifted the unrealistic restrictions that have held this research back for so many......
