Understanding the Stem Cells.
The forefront of medical technology is the research on stem cells. Understanding the whys and hows of stem cells field of medicine will lead to understanding the controversy related to them. This website will briefly discuss the stem cells and their controversy. To begin with, it is important to understand the stem cells. Simply, these are cells that can separate into, unlike cells. They can also be referred to as cells which have not yet reached their potential. They a cells that can be used into whatever including sells for vital organs such as heart or liver. There is an example to this which is the zygote formed by the sperm and an egg to become an entire organism in the process of reproduction. This process is controlled by the gene differentiation.
The stem cells are from two main categories. The embryonic stem cell is one main category pulled from 3 to 5-day old embryo. The activists have more concern on embryonic stem cell. They are more useful because they tend to be harder and can form a wider variety of tissues. The second category is the adult stem cells that can be obtained from bone marrow or fatty tissues of a certain patient. These type of cells are usually limited in their ability to change into the different types of tissues as well as number.
The researchers consider these cells as important as they conform regenerative medicine. If injected and the right conditions are met, these cells are able to replace damaged, malignant tissue or scarred. This is particularly important for a brighter future where damaged and scarred heart can be healed. They are important as they are a valuable tool to be used by the researchers. These cells are important in completely revolutionizing the modern medicine and research.
The major controversy in stem cell research is based on the sourcing of embryonic stem cells as discussed in this page. It is considered an ethical issue by many people as they originated from human embryos. This fueled by religion that battles science which is seeing a discourse in modern politics. In the modern world, many people are preferring the modification of adult stem cells rather than the use of embryonic stem cells. The technique used to extract embryonic stem cells is regarded as destructive since an embryo has to be destroyed in order to acquire the stem cell which is forming a major controversy.
The valid counterpoints used against this controversy are discussed here. There is roughly 33% of zygotes that do not properly bond with the uterine wall hence many embryos get destroyed that could be used for research. The importance of adopting stem cell treatment as that some clinics offer treatments for many issues with no known treatment. The future of the stem cell is likely to be realized if there is a potential of iPSC technology.
