...The Trials of Stem Cell Therapy Stem Cells: Plenty of Hope, but Halting Progress By KAREN WEINTRAUBSEPT. 15, 2014 Photo Embryonic stem cells, from a woman with Type 1 diabetes, were induced to turn into insulin-making beta cells, in hopes they could be implanted to cure the disease. Credit Bjarki Johannesson/New York Stem Cell Foundation, via Reuters Edgar Irastorza was just 31 when his heart stopped beating in October 2008. A Miami property manager, break-dancer and former high school wrestler, Mr. Irastorza had recently gained weight as his wife’s third pregnancy progressed. “I kind of got pregnant, too,” he said. During a workout one day, he felt short of breath and insisted that friends rush him to the hospital. Minutes later, his pulse flatlined. He survived the heart attack, but the scar tissue that resulted cut his heart’s pumping ability by a third. He couldn’t pick up his children. He couldn’t dance. He fell asleep every night wondering if he would wake up in the morning. Desperation motivated Mr. Irastorza to volunteer for a highly unusual medical research trial: getting stem cells injected directly into his heart. “I just trusted my doctors and the science behind it, and said, ‘This is my only chance,’ ” he said recently. Over the last five years, by studying stem cells in lab dishes, test animals and intrepid patients like Mr. Irastorza, researchers have brought the vague, grandiose promises of stem cell therapies closer to reality.

...3 22/1/17 Embryonic Stem cell research paper Stem cells, the argument between. There has been great controversy over whether or not stem cells should be allowed to be used in research. The greatest problem we run into over this is where the stem cells actually come from. The cells come from embryos that are 3-5 days old. This creates the problem of safety for both the unborn child and the mother. “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.” (Stem) The National institute of health made the remark of how stem cells can be used. They are unspecified cells, this means that they can become almost any type of cell. Although, it is considered unethical to extract these cells from unborn children, they could be useful to many. These cells could be a huge improvement for cancer patients of even trauma patients to help repair damages to their bodies....

...Simran Mann Negative Opinion Paper Biology 3000 Harvesting Embryonic Stem Cells Harvesting embryonic stem cells can be an argumentative topic with differing opinions. I believe by researching and experimenting on embryonic stem cells, the results can be beneficial to society through medical treatments. I believe this research will benefit medical science into further advancement. The human body contains more than 220 differentiation cell types that are acquired from a collection of cells that are referred to as embryonic stem cells. Furthermore, these cells originate from an embryo, within the inner cell mass of a blastocyst that is known to be five days old. Moreover, these cells are classified to be pluripotent, which can individualize inside any three layers of the germ. Thus, embryonic stem cells are able to reform relatively any part of the human body. In addition, these cells are capable of cloning endlessly. As a result, these cells can benefit in medicine for both regenerative medicine and medical research. Regenerative therapy is the process of reconstruction or substitution of new tissue developed with the supervision of embryonic stem cells caused by obscured and impaired tissue from a disease or injury. Therefore, when the stem cells are injected into the patient’s body, those cells locate to the injured area and begin to diffuse and expand by renewing the injured cells; thus, recovering the bodily functions in that area. A few of the illnesses that can be...

...was viewed as seismic shift was to good to be true. The original study done by Riken Center for Developmental Biology in Kobe, Japan, found a simple acid bathin that might turn cells in the body into stem cells that could one day be used for tissue repair and other medical treatment. The techique, peformed only with cells from mice, might turn out to be a quicker and easier source of multipurpose stem cells than methods now used. Th prestigious Japanese institute, apologized days later after the article was printed, saying the work contained "serious errors", the institute was examining whether to retract the papers, which had appeared to offer a revolutionary new approach to creating stem cells. Dr. Noyori repeatedly referred to Haruko Obokata, the 30-year-old lead author of the papers, as "immature" and "sloppy." He said an investigation was continuing into the most serious allegations—in particular, the question of why three images in the papers were nearly identical to three images included in Dr. Obokata's 2011 doctoral dissertation at Japan's Waseda University. The stem-cell papers were published in late January in the journal Nature, which has said it is investigating the irregularities. The controversy has highlighted the race for improved methods of creating stem cells, long seen as a potential source of cures for heart disease, diabetes and other ailments. It has also pointed to apparent lax controls at one of Japan's top scientific institutions. Dr. Obokata...

...Stem Cell research is a very controversial topic in today’s society. This topic brings up many ethical questions about it is right to do the research or not. Stem cells come from embryos that are only a few days old. The ethical issues that arise are many. If one believes that an embryo is a baby upon fertilization, then one would feel that this was unethical to do the research no matter what the benefits would be. On the other hand, some feel the benefits of what can be learned from stem cell research outweighs the ethical and moral dilemmas that are argued. This long debate brings about many questions about the ethical approaches, that there have been restrictions placed on the research in the lines of what type of embryos can be used for the research. Ethical or not there are always two sides to debate, stem cell research is no different. Throughout this paper I will discuss the ethical issues that stem cell research brings into light and the benefits that stem cell research brings into light that may just outweigh the ethical issues, then determine it these benefits and ethical issues really make stem cell research the most beneficial way to help cure diseases such as juvenile diabetes, Parkinson’s disease or even spinal cord or neck injuries. Argument for Research Stem Cell research can help scientist discover more about human cells and how they grow, change, and replace damaged cells within the body. The information that can be learned is priceless. Using this research...

...Stem cell research and therapy Stephanie Reeves Rasmussen College Author Note This paper is being submitted on August 3, 2014, for Ellen Doyles’ Human Biology course. Stem cell research and therapy Stem cell research has great significance for medical use. They have the ability to develop into many different cell types in the body during early life and growth. They can also serve as a repair system to many tissues, by dividing without limitation to replenish other cells as long as the person or animal is still alive. Stem cells are the body’s raw materials. Stem cell research has created quite the controversy and has been a topic of debate for over a decade. There are 3 types of stem cells that are currently being used in stem cell research and therapies; Embryotic, Adult, and induced pluripotent stem cells. There are a few characteristics that differ between these types of stem cells Embryotic stem cells can become all cell types of the body because they are pluripotent, and can be grown relatively easy in culture. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue origin, and are rare in mature tissues which makes it difficult to isolate these cells in adult tissue, and methods to expand their numbers in cell culture has not been worked out as of today. Induced pluripotent stem cells are adult cells that have been genetically altered to have properties of embryonic stem cells. ...

Arguably, one of the most divisive scientific advances of the twentieth century and likely an advance with the most potential to improve the wellbeing of mankind; is met with an equal amount of derision and moral objection. The human embryo is nothing more than a mass of stem cells, or cells without specific function, yet. The embryo isn’t likely to have feelings or sense of awareness, but it is how every human starts life and if given roughly 14 days in the womb, would develop the beginnings of a heart, brain and...

...Jean-Marie Lux Biology 121 Stem Cell Research Paper September 12, 2012 Stem cell research is a relatively new field and has made huge advances in the past fifty years. The idea of stem cells was first made public by a Russian-American Scientist named Alexander Maksimov in 1908. However it was not until 1963 that two Canadian Scientists were able to actually demonstrate the existence of self-renewing cells found in the bone marrow of mice. The Scientists were James E. Till and Ernest A. McCulloch. So although Maksimov was the first person who put the idea of stem cells out there, it is really Till and McCulloch who are credited with proving that stems cells actually existed. Since Till and McCulloch, many Scientist have contributed to the huge advances in stem cell research. In 1968, the first successful bone marrow transplant was conducted on two siblings suffering from Severe Combined Immunodeficiency (SCID), a primary immune deficiency which typically results in the onset of one or more serious infections within the first few months of life. These infections are usually serious, and may even be life threatening. In 1978, the presence of Haematopoietic stem cells were discovered in human cord blood cells. Haematopoietic stem cells, are multipotent stem cells that give rise to all the blood cell types. In 1981, Scientist were able to derive embryonic stem cells from mice. One of the biggest advancements in all stem cell research came in 1997 when a link between...

According to Lanza, A simple definition for stem cells is as follows “a stem cell is a cell that has the potential to develop into a number of different types of cells in the body.” (2011). Basically, stem cells are the base of all organs and tissues in the human body, a master cell of some sort. Stems cell, also have the potential be the backbone of many medical breakthroughs in centuries to come, from age prevention to helping with disabilities such as blindness, inability to walk, etc... As mention earlier in this paper there are many types of stem cells, but for purpose of this paper I shall focus on adult & embryonic stem cells. An adult stem cell is an undifferentiated cell that is found amongst differentiated cells in an organ or tissue that processes the ability to renew itself, as well as differentiate into other specialized cell types. By their nature, adult stem cells aren’t as controversial as embryonic stem cells...

How does it compare to comparable statutes in the rest of the world? In this paper talk about what the current legislative state of affairs is and where the law on stem cells in the United States should go in the future and why. Make sure you use ample research and cited sources to support your arguments but make sure to state your own opinion on the issues as well. Stem Cell Research TJ AS OF: 2/4/2009--Introduced. Stem Cell Research Improvement Act of 2009 - Amends the Public Health Service Act to require the Secretary of Health and Human Services to conduct and support research that utilizes human embryonic stem cells, regardless of the date on which the stem cells were derived from a human embryo. Limits such research to stem cells that meet the following requirements: (1) the stem cells were derived from human embryos donated from in vitro fertilization clinics, were created for the purposes of fertility treatment, and were in excess of the needs of the individuals seeking such treatment; (2) prior to donation, it was determined that the embryos would never be implanted in a woman and would otherwise be discarded; and (3) the individuals seeking fertility treatment donated the embryos with written informed consent and received no financial or other inducements.

...Jody Vaughn Research Draft Since the 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...

...SBI4U ISP Part II: Genetic Technology Research Paper Embryonic Stem Cell Use Abstract: Researchers discovered that embryonic stem cells could be originated from early human embryos. This discovery has raised a series of ethical and public-policy questions that are now being confronted by multiple international organizations, nations, cultures, and religious traditions. This essay surveys policies for human embryonic stem cell research in four regions of the world, reports on the recent debate at the United Nations about one type of such research, and reviews the positions that various religious traditions have adopted regarding this novel type of research. In several instances the religious traditions seem to have influenced the public-policy debates. There are many ways in which human stem cells can be used in research and the clinic. Studies of the medical use of Embyonic Stem cells will yield information about the complex events that occur during human development. A primary goal of this work is to identify how undifferentiated stem cells become the differentiated cells that form the tissues and organs. Scientists know that turning genes on and off is central to this process. Some of the most serious medical conditions, such as cancer and birth defects, are due to abnormal cell division and differentiation. A more complete understanding of the genetic and molecular controls of these processes may yield information about how such diseases arise and suggest new strategies...

...Stem Cell Research Legislation Manny Garcia Jr English 135 Ms. Miller February 12, 2010 Abstract This paper explains that the ethical dilemma involved in stem cell research is a rather straight- forward process because to achieve its full potential this type of research requires using stem cells from fetuses. As well the history of Stem Cell Research Legislation in United States and what the current legislature state of affairs is and where the law on stem cell should go in the future. The issue of stem cell research burst on the scientific in November of 1998 when researchers first reported the isolation of human embryonic stem cells. The discovery, made by Dr. James A Thomson, a biologist at the University of Wisconsin, Madison, offered great promise for new ways of treating disease. The cells, which are derived from several day old embryos, can theoretically differentiate into virtually any type of human cell, from blood cells to skim cell. Scientists hope to find ways of using them to repair damaged tissue. Although research is only in the early stages, there is a growing consensus among researchers that many very effective medical treatments can be realized through cloning stem cells. This is because these cells can be made to replicate specific human tissues. These cells offer the possibility of a renewable source of replacement cells and tissue to treat a myriad of diseases, conditions, and disabilities including Parkinson's and Alzheimer's diseases, spinal...

...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 are...
