Stem Cell Research

Introduction Unique functional cells such as for example, a red blood cell start out originally as unspecialized cells known as stem cells. These stem cells have the uncanny ability to keep separating through division and multiplying in culture to produce specialized cell for a specific bodily function. In the context of normal human development, they are best described for their diversity, adaptability and longevity. As the laws of biology dictate, a human being is formed when a sperm cell fertilizing a female egg cell to produce a zygote. The zygote is already specialized in the fact that it is on the way to the formation of a whole individual. Furthermore the zygote, also known as the fertilized egg is tot potent that simply implies that its potentials have reached their maximum. This zygote will then start to divide profusely. When numerous frequencies of cell division have taken place and over four days have passed since fertilization, a hollow sphere is formed from the tot potent cells that have stemn as a result of proliferate cell division, giving rise to what is known as a blast cyst. An outer layer of cells exist in the structure of the blast cyst. However inside this structure known as the blast cyst, there is a cluster of cells known as the Mass of inner cells that are very valuable for biological scientists.[1]

Stem Cell Potential Will stem cell-based treatments be constrained by immune rejection? Much of the motivation for stem cell exploration comes forward from the fact that stem cells and the differentiated cells that are derived from them will someday prove to be the most successful source of transplantation treatments for the multitude of human diseases. The fact remain that it may be too expensive and too time consuming to derive meaningful amount of stem cells that will be large enough in quantity to serve the purpose for the specialised cell differentiation. This will also mean that individual stem cells will be used to cure various individual patients. Most scientific individuals would testify to the fact that it is too early to make any conclusions on the area of interest such as the utilization of stem cell for human transplantation; however it may be wise to draw some primary information about the present state of affairs in this area of research. The fact that embryonic, adult and fetal tissue can be used to derive stem cells is sufficient to prove that the application of stem cell in disease alleviation is tremendous. In exceedingly giving locality of research seems to be the utilization of stem cell for transplantation of human constituents and eradication of ailments in human beings. It is evolving new research apparatus, new details and numbers about pathways of cell differentiation and unfastening new vistas of cell transplantation remedy for human diseases. Heterogeneous human stem cell groundwork drawn from skeletal marrow has been in clinical use as remedy (bone marrow transplants) for diverse types of cancer for numerous years. More recently, hematopoietic stem apartments have been isolated and purified from skeletal part marrow and are being modified. Because this is a clinically well-established of present wellbeing remedy, we will not aim it farther in this report. Rather than we will aim on new types of stem cell groundwork, and ways in which they might be utilized in research and wellbeing remedy. Skeletal Bone Marrow that is decimated by disease, chemo, or radioactive emission can be refurbished by utilizing stem cell transplants. For certain infectious ailments, body-fluid infections, and many infections of the defense cell, and the cells that are known as stem cells in the skeletal bone marrow do not effectively function the way that it is intended to function. As these recipient bodies do not accept the donor cell, the cells that are known as stem cells are subjected to rejection. This paper will look to enquire the benefits to following stem cell research in human transplantation. Introduction Stem cell transplantation can provide a very effective method of recuperation in certain cases of diseases like myopias, leukemia and other blood borne diseases. Stem cell transplantation helps to curb down damage of cancerous diseases when compared to other conventional treatments like chemo therapy and other treatments. The problem with this is that the exposure to radiation and that too of a high dose can retard the production of red blood cells in skeletal marrow that can cause further exasperation of the disease or ailment.[2] In cases like this, the stem cell transplantation can be a valuable addition to the arsenal of treatment of the patient. Stem cells can often be used in this way to overcome problems of blood production, because chemotherapy and radiation can damage the cell producing marrow in the bones. The topic transplant allows qualified clinical physicians to utilize [pic]larger and larger doses of chemotherapy irradiation that will endeavor [pic]and try to eradicate [pic]most of the cancerous infection sites. The hazards adhered with the cancerous disease [pic]ailments when compared to the hazards of [pic]the procedure of transplant. Transplantation hazards [pic]are of seriously grave concern and deaths have been known to occur from such adversities. Nearly each and every tissue of the human body is known to form from this very collection of cells known as the inner cell mass. The inner cell mass is known as the building blocks of the human organism, because even though they are capable of forming into each and every tissue and functional structure present in the human body, they are not capable of forming a separate living entity like an organism on their own. Pluripotent cells are the term given to describe this inner mass of cells that are capable of contributing to all tissues and structures related to fetal development. A particular function is derived when these very pluripotent cells undergo further cell division and differentiation for specialization. The resulting specialized cells also known as stem cells are what are termed as multipotent cells. These multipotent cells are very important for early human development in addition to being found in children and adults as well. It is these particular stem cells that are extremely pried in the medical community today for their unique purpose and their use is a study and subject of constant debate that has elucidated the minds of many common people and scientists alike. In some cancers, such as certain leukemia, multiple myeloma, and some lymphomas, a stem cell transplant can be a significant constituent of remedy. High doses of chemo or emission work better than benchmark doses to murdering cancerous infection cells. But high doses can furthermore source the skeletal part marrow to methodically halt making body-fluid cells, which we need to, reside.[3] This is where stem cell transplants reach to in. They can be utilized to supersede the body’s source of body-fluid cells after the skeletal part marrow and its stem apartments have been destroyed by the remedy. The topic transplant allows wellbeing practitioners to utilize much higher doses of chemo irradiation to endeavor to murder all of the cancerous infection cells. The hazards adhered with the cancerous disease itself versus the hazards of the transplant procedure. Transplant hazards are serious, and death can occur as a result of these adversities. The stage of the contamination, patient’s age, and time from diagnosis to transplant, donor kind, and the patient’s general wellbeing are all constituent of weighing the pros and cons before making the deduction. While, a relinquished security study undertook in an assembly [pic]of patients over a 5 year time span exhibitions plentiful security and negligible adversities affiliated with mesenchymal cell transplantation. Early each and every tissue of the human body is known to form from this very collection of cells known as the inner cell mass. The inner cell mass is known as the building blocks of the human organism, because even though they are capable of forming into each and every tissue and functional structure present in the human body, they are not capable of forming a separate living entity like an organism on their own. Pluripotent cells are the term given to describe this inner mass of cells that are capable of contributing to all tissues and structures related to fetal development. A particular function is derived when these very pluripotent cells undergo further cell division and differentiation for specialization. The resulting specialised cells also known as stem cells are what are termed as multipotent cells. These multipotent cells are very important for early human development in addition to being found in children and adults as well. It is these particular stem cells that are extremely pried in the medical community today for their unique purpose and their use is a study and subject of constant debate that has elucidated the minds of many common people and scientists alike.

Stem Cell Treatments It is the belief of the top researchers in medicine that the precept of human infliction can be completed resurfaced with the aide of these stem cells and their use in treatment options for patients. With the most well-known exception of bone marrow transplantation, which is now accepted and used in hospitals worldwide, the treatments associated with stem cells and their effective usage are both very expensive and very experimental in nature. All stem cell treatments have been theoretically validated to provide the most comprehensive treatment for the existing ailment but its practical and ethical limitation prevent it from becoming a staple in medical administration. Most diseases and impairments, notably those like cancer, diabetes of the type 1 order, injuries to the spinal cord and muscular damage have been anticipated by medical specialists and field researchers to be radically treated through the use of technologies that have been derived from adult and embryonic stem cells. Using these adult stems cells have resulted in the discovery of several treatments for several different diseases. Another obvious advantage that adult stem cells possess over embryonic cells is the ability to be accepted by the patient because they are taken from the patient. There is a great amount of uncertainty of the social and scientific implications of stem cells that still exists in the scientific community. But by years of ongoing research, a multitude of successful treatments and ongoing acceptance of the public will eventually overcome the skepticism that stem cells face. Hindrance in the ultimate goals of stem cell therapeutics is furthermore aided by many technical difficulties, which persist even today. A large problem which seems to elude the scientific community is that which requires the extraction of increasingly large stem cell populations from the patient. Another issues that haunts scientists and doctors is the fact that even of these stem cells are efficiently extracted from the patient, they may not be grow, developed and expand in number effectively to add to the corrective function that they are intended to provide. Many similar technical anomalies like this remain to be solved in order to see the absolute application of stem cells in the medical field.

Current treatments Most cancer patients that suffer from debilitating conditions like leukemia and lymphoma have been treated successfully using the very same stem cells that have been removed and isolated from the bone marrow and umbilical cord blood. It is common for cytotoxic agents to kill all kind of growing cells during a session of chemo therapy in which living human tissue is exposed to intense radiation of a damaging kind. Unfortunately the hematopoietic stem cells within the bone marrow are also killed or damaged along with the eradication of the leukemia and neoplastic cells. Transplant endeavors to turn around; the donor's healthy skeletal marrow reintroduces purposeful stem cells to restore those lost in the treatment. In all present Stem Cell treatments obtaining stem units from an agreed Donor is preferable to using the patient’s own. If (always as a last holiday resort and generally because no agreed Donor can be discovered) it is regarded essential for the patient’s own stem cells to be utilised and the persevering has not retained their own collection of stem cells (umbilical cord blood), bone marrow samples must thus be removed before chemotherapy, and are re-injected afterwards.

Conclusion Presently research is expressed out on both mature one-by-one and embryonic stem cells. Research on mature one-by-one stem cells has been taking place for more than 30 years, and has not been subject to ethical remonstrations, while research on stem cells got from embryos is a centralized theme in the perpetual ethical contention, because the embryo is decimated in the procedure. [4] The adult individual cells and embryonic stem cells contradiction in more ways than the number of cells they can differentiate into; mature one-by-one stem cells are harder to isolate and augment, and to propagate in plentiful allowances. It is still not renowned, if the maturation of one or both stem cell types can be controlled in such a way that they can conceive a base for the yield of cells for transplantation in the future. After reconsidering these details, one can make the deduction that the use of stem cells is the wonder drug of the century, one that will cure all infections. It is the fact that stem cells can be used to treat diseases like cancer, leukemia, blood cancers, baldness, teeth deformities, brain strokes and other ailments that are basically not possible to be treated with the existing conventional methods that are available. While this might appear to be the case, there is one part left out of the overhead explain. Stem cells are derived from a developing embryo or fetus. There is no other position to find absolutely undifferentiated cells than in an undeveloped human. Regrettably, a developing human yearns those units; the method of eliminating them killings the unborn progeny. In effect, an abortion is presented when stem cells are got. This has started an outcry from pro-life activists. The lesson contention is that scientists are murdering fetuses to accelerate the health status of dwelling patients. They state that using stem units in this kind is precisely the equal thing as using fetuses to ranch body constituents. While it might be factual that the medical practitioners who discovered the pledge use of stem cells begin from the baby-boomers, the reason they impel for the use of stem units is because they are medical practitioners. They took an oath to save the lives of their patients, and stem cell treatment is one way to do so. Addressing his “destruction of life” contention, when a woman has an abortion, the fetus or embryo is hurled out, utilizing aborted tissue to pattern units lost in otherwise incurable diseases and wounds is probably the best thing to do for both the unused stem cells and the persevering. rather than of incinerating aborted tissues, there is no cause that medical practitioners should not be adept to use them to save dwelling life. Stem cell study is unavoidable if the wellbeing world wishes to be proficient to fix impairment interior the human body. While it is factual that getting stem cells destroys life, the benefit to the bigger good considerably outweighs the decimation of promise life producing from a fertilized egg. With an infinite supply of stem units from just a couple of lines, all defective tissues can be restored. Those engaged in the health world can considerably advance the quality of human life. With stem cells utilised in general present in clinics, persons will live longer, healthier, lives. Numerous diseases would be absolutely eradicated, and wounds would stop to be crippling to so numerous individuals. Furthermore only when researchers and medical practitioners completely understand how to implement the embryonic stem cell, can all this occur. With funding and support for just a handful more stem cell lines, the medical world could be supplied with an infinite number of stem units to treatment patients. When medical practitioners have all of the lines they need, then they can stop decimating embryos to get the stem units they need. The biological world and the locality of stem units expressly, need the support of the government as well as the individuals to make this likely.

Human Embryonic Stem Cells

...Introduction Human embryonic stem cells (hES cells) are currently discussed not only by the biologists by whom they were discovered but also by the medical profession, media, ethicists, governments and politicians. There are several reasons for this. On the one hand, these ‘super cells’ have a major clinical potential in tissue repair, with their proponents believing that they represent the future relief or cure of a wide range of common disabilities; replacement of defective cells in a patient by transplantation of hES cell‐derived equivalents would restore normal function. On the other hand, the use of hES cells is highly controversial because they are derived from human pre‐implantation embryos. To date, most embryos used for the establishment of hES cell lines have been spare embryos from IVF, but the creation of embryos specifically for deriving hES cells is also under discussion. The most controversial variant of this is the transfer of a somatic cell‐nucleus from a patient to an enucleated oocyte (unfertilized egg) in order to produce hES cells genetically identical to that patient for ‘autologous’ transplantation (so‐called ‘therapeutic’ cloning); this may prevent tissue rejection. The question ‘Can these cells be isolated and used and, if so, under what conditions and restrictions’ is presently high on the political and ethical agenda, with policies and legislation being formulated in many countries to regulate their derivation. The UK has been the first to pass...

...Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. Stem cells are cells found in all multi cellular organisms. Stem Cells have the potential to make a large positive impact in the medical field. It is important to know the basics of Stem Cells, the difference between the types of Stem Cells, and the possible uses of Stem Cells. Knowing the basics of stem cells is a necessity to understanding how they might positively impact those with a medical condition. Stem cells are master or parent cells of the body. Stem cells are unspecialized cells. They have special properties: unspecialized cell and the ability to self-renew as a stem cell or transform into another type of cell with a specialized function. The human body has over two hundreds different types of cells. The stem cell has the potential to replace about all of them. Stem cells are considered unique compared to mature cells which are lack of their capabilities. Stem cells have the remarkable potential to develop into many different types of cell in the human body. Spinal cord injury results in neuronal degeneration and demyelination due to oligodendrocyte apoptosis at the region of trauma and causes severe functional impairment of motor and sensory pathways (All, 2012). With the right conditions in the human body or a laboratory, the stem cells divide to form more cells, or daughter cells. These daughter cells either become new...

The Birth of an Alternative: Using Umbilical Cord Stem Cells to Improve Stem Cell Research

...Cord Stem Cells to Improve Stem Cell Research Stem cells are intriguing. They are so dynamic, so puzzling, and they contain many of biology’s deepest mysteries. Generally, cellular stemness is characterized by a cell’s self-renewal and potency, the ability to differentiate into specific cell types. In reality though, the science of stem cells goes beyond these distinctions. From studying human development to creating new therapeutic alternatives for diseases, embryonic stem cell (ESC) research promises numerous benefits as it has progressed extensively in the past decade. But because of the ethical issues surrounding the destruction of human embryos, other alternatives have had to be found. So far, adult stem cells (ASCs) have been used for therapeutic purposes such as bone marrow transplants. However, donor DNA-matching has been an enduring problem with this approach. A few years ago, Shinya Yamanaka discovered induced pluripotent stem cells (iPSCs), which derives pluripotent stem cells from somatic cells, thereby overcoming both ethical and donormatching issues. Although iPSC presents much promise, the newness of this technology makes it inadequate for immediate use. Now, newer discoveries have been made. Aside from ESCs, ASCs, and iPSCs, stem cells have also been found in postnatal tissue, particularly in the umbilical cord. These umbilical cordderived stem cells have been proposed to treat illnesses ranging from Parkinsonism to leukemia in both animal models and humans alike...

Until recently, moral issues of states and countries haven't allowed research to expound deeply into the unknowns. Within the last ten years though, scientists have made leaps and bounds in finding out concrete facts that this stem cell research has supplied. Tommy G.

Cloning

...Karren Mrs. Robertson English 5A 12 December 2012 Human Therapeutic Cloning Should Be Permitted Human therapeutic cloning has the ability to greatly improve the quality of life. Cloning could be the answer to the end of your pain and suffering, but before you can understand it’s benefits, you have to know the process therapeutic cloning itself. Therapeutic cloning is a procedure in which cells, typically skin cells, are taken from a patient and inserted into a fertilized egg whose nucleus has been removed. Scientists then extract stem cells from the egg, and use those cells to grow tissue that are a perfect genetic match to the patient. It is a break-through in science and the key to curing many diseases including Parkinson's and Alzheimer's disease. Elizabeth Foley explains why human cloning should not be banned due to, “the primary objections to human cloning appear to be unfounded, based more on morality, theology, and fear than objective data.” The potential medical benefits of genetic engineering are far too great to let moral concerns about embryonic cell use get in the way of curing diseases. Human therapeutic cloning should not be banned from society because countless lives can be saved through transplantations and genetic research. Therapeutic cloning is the cloning of human tissues for research and transplant, and shows much promise in organ transplantation. Much needed organs grown from stem cells from the patient’s own genetic material could help solve...

Stem Cells & Cardia Disease

...Stem cell research is one that is widely debated amongst various religions, cultures, and political groups. The question as to when life actually begins is the epicenter of this worldwide quarrel, and may not be settled for some time. Although this may be true, one fact that cannot be denied is that stem cell research has led to many life saving discoveries in various sectors of scientific research. In regards to the ethical dilemma of stem cells, recent developments in induced pluripotent stem cells (iPSCs) have made it possible to explore the applications of stem cells while avoiding the ethical problems associated with embryonic stem cell research (Seki & Fekuda, 2015). One intriguing area in stem cell research is the potential applications for them in the treatment of cardiac diseases. Studies have explored the potential uses for stem cells for the treatment of heart disease (Yamakawa & Ieda, 2015). Additionally, stem cells have been explored for the treatment of heart failure and myocardial infarction (Rasmussen, et al., 2013). Stem cells and how they may be used for the treatment of various cardiac diseases is an exciting topic and has the potential to change future approaches to the treatment. This paper will examine the applications and significance of stem cells in relation to these common cardiac pathologies.

...its protein product, which can then be purified and used for biochemical experimentation. Cloned genes can also be used for DNA sequencing, which is the determination of the precise order of all the base pairs in the gene. All of these applications require many copies of the DNA molecule that is being studied. Gene cloning also enables scientists to manipulate and study genes in isolation from the organism they came from. This allows researchers to conduct many experiments that would be impossible without cloned genes. For research on humans, this is clearly a major advantage, as direct experimentation on humans has many technical, financial, and ethical limitations. Importance for Medicine and Industry The ability to clone a gene is not only valuable for conducting biological research. Many important pharmaceutical drugs and industrial enzymes are produced from cloned genes. For example, insulin, clotting factors, human growth hormone, cytokines (cell growth stimulants), and several anticancer drugs in use are produced from cloned genes. Before the advent of gene cloning, these proteins had to be purified from their natural tissue sources, a difficult, expensive, and inefficient process. Using recombinant methods, biomedical companies can prepare these...

The polio vaccine was invented in the 1950’s from the use of human fetal kidney cells, fetuses in uteri were used to develop techniques like amniocenteses and improving knowledge about congenital heart disease in the 1970’s, and in the 1980’s the transplantation of fetal tissue into adults to help with serious conditions like, diabetes or Parkinson’s (Gold, 2004). While there has always been concern and controversy over the use of human embryonic cells, today the debate is ethical. This ethical debate lies within the destruction of human embryos in order to use them for medical research. This paper will talk about how two different theories; utilitarianism and relativism view this ethical issue and the problem it presents, as well as my personal views on use of embryonic stem cell research. The theory of utilitarianism determines what is best by looking at the results of an act. According to Mosser (2010, section 1.7), “utilitarianism argues that, given a set of choices, the act we should choose is that which produces the best results for the greatest number affected by that choice.” When looking at the use of embryonic stem cells for research, utilitarianism looks at the end result. Embryonic stem cells have the potential to save lives by curing diseases and through the use of transplantation. While some utilitarianism’s may still view the destruction of these cells as the...

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 Cells

...Recent advances in human stem cell research have not only generated enormous enthusiasm on the part of researchers and optimistic predictions of revolutionary advances in biomedicine, but have also sparked considerable ethical and emotional public debate. There has been much controversy in the press about pros and cons of stem cell research . The important question to think about is Why the prospect of stem cell therapy has been greeted not as an innovation to be welcomed but as a threat to be resisted? The enormous capabilities of stem cells announce the beginning of an extraordinary advanced field of medicine that can help to cure deadly diseases . The present method , however, destroys human blastocyst that gives rise to intense controversy. (Monroe, Miller, & Tobis , 2008, p. 1) Stem cell controversy is the ethical debate centered on research involving the creation, usage and destruction of human embryonic stem cells. Around the world, many people believe that human embryo research , including the deliberate creation of embryos for valid research or clinical purposes , is wrong . Due to the controversy , some people argues that we should allow stem cell research but some of them are not in favour of stem cell research . According to S Holm , the author of Going to the Roots of Stem Cell Controversy, “A stem cell is a non – differentiated cell that can divide and multiply in its undifferentiated state, but which can also give rise to more specialized...

Embryonic Stem Cells In The Body

... what are stem cells? Stem cells have the remarkable ability to possibly develop into numerous different cell types in the body, not only during the early stages of life but throughout the growth of the body as well. Along with that, stem cells can serve as an internal repair system in certain body tissues. A unique factor of stem cells is that when they divide each newly formed cell can potentially reform into a new type of specialized cell such as a muscle cell, a red blood cell, etc. By doing this, the body can become stronger or gain back important cells that it has lost. Another unique characteristic of stem cells is that under certain physiological conditions they can be induced a tissue or organ specified cell with special...
