Stem cells are the somewhat miraculous cells formed in the firstfew days after an egg is fertilized by a sperm: they have thepotential to grow into any of the 220 cell types that make up thehuman. - stem cell research stem cell research is a highly debated, controversial, sensitive topic too many people have skewed perceptions of stem cell research simply due to their lack of knowledge on the topic. Stem cells are cells with the ability to divide and differentiate into a variety of cells embryonic stem cells are the variety that are found in the human embryo and can differentiate into the widest variety of cells they are harvested from leftover embryos from in-vitro procedures the problem. The stem cell controversy is the consideration of the ethics of research involving the development, use, and destruction of human embryos most commonly, this controversy focuses on embryonic stem cells. Most arguments against stem cell research are philosophical and theological, focusing on questions of whether or not we should be taking science this far the use of embryonic stem cells for research involves the destruction of blastocysts formed from laboratory-fertilized human eggs.
The social justice inquiry is relevant to many areas of biomedical research, not just stem cell research indeed, such an inquiry might support research on some conditions that are the focus on stem cell research, such as juvenile diabetes and spinal cord injury, which affect many young people. Stem cells: looking towards the future this may seem like a unreligious view, but stem cell research is neccesary for our future just think of all the people who are suffering, and how we could lessen that pain. Findings from research on embryonic stem cells, such as methods to create various types of cells, have been applied to ips cell research that's why ips cell research has evolved so rapidly. J leslie glick, phd in 2009, president obama removed restrictions on federal funding of research on new stem cell lines derived from spare human embryos created by means of in vitro.
In conclusion , even though people say it is not ethical or right to do stem cell research, scientist should continue using stem cells because the embryos that are already aborted should be used for something that is going to be useful for us. Stem cell research holds incredible healing potential, but embryonic stem cell research isn't the key to that potential we should not continue with embryonic stem cell research because it lacks. Stem cell research should continue because it holds the most potential for developing medical treatments and cures for diseases or conditions that as of yet have no treatment or cure a lot of knowledge that would be beneficial to the medical field can be gained from this type of research.
Stem cell research is a relatively new technology that takes primitive human cells and develops them into most any of the 220 varieties of cells in the human body, including blood cells and brain cells. Until recently, the only way to get pluripotent stem cells for research was to remove the inner cell mass of an embryo and put it in a dish the thought of destroying a human embryo can be unsettling, even if it is only five days old. Those from bone marrow (bone marrow stromal stem cells, skeletal stem cells) give rise to a variety of cell types: bone cells (osteoblasts and osteocytes), cartilage cells (chondrocytes), fat cells (adipocytes), and stromal cells that support blood formation.
The benefits of stem cell research outweigh the cost in terms of embryonic life embryonic stem cells have the capacity to grow indefinitely in a laboratory environment and can differentiate into almost all types of bodily tissue. The best-defined and most extensively used stem cell treatment is hematopoietic (or blood) stem cell transplantation, for example, bone marrow transplantation, to treat certain blood and immune system disorders or to rebuild the blood system after treatments for some kinds of cancer. Conclusion the stem cell-research is an example of the, sometimes difficult, cost-benefit analysis in ethics which scientists need to do even though many issues regarding the ethics of stem cell research have now been solved, it serves as a valuable example of ethical cost-benefit analysis. In the 27 years since the advent of embryonic stem-cell research in 1981, scientists have still not demonstrated the ability to control the cells and their attendant risk of tumor formation, inappropriate tissue growth and immune rejection, and the leading researchers continue to note that it will be decades at best before embryonic stem cells.
Therefore, embryonic stem cells should be an important part of stem cell research even if induced pluripotent cells can replace embryonic cells in the future, the knowledge gained from current embryonic cell research would still be very applicable. The australian academy of science has been pleased to promote public debate on human stem cell research, by publication of a position statement on human cloning (february 1999), by providing information on the. (hli worldwatch) - much of the confusion over stem cell research involves misunderstanding of terms, so let's begin with some definitions stem cells are immature cells that are. Stem cell research has done amazing things and it is still only in the beginning stages if scientists can perfect the use of stem cells, even those with paralysis and horrible diseases will be cured.
Should adult stem-cell research be allowed to continue: by all means yes yes yes yes to date, we have cures or at least progress toward cures for at. For example, embryonic stem cells that have matured into insulin-producing cells in the lab are only useful if they continue producing insulin once transplanted inside a body likewise, researchers need to know that the cells can integrate into the surrounding tissue. Stem cells, however, can change into many types of cells -- heart cells, nerve cells, muscle cells, skin etc that is why they are called stem cells they are the stem or trunk from which the branches (different cell types) can proceed. Since most of the current stem cell lines are in the commercial sector and the president has banned the creation of new lines, she worried that universities would not continue to be centers of research in this important area.
