Understanding the Stem Cells.
The medical technology has put research on stem cells at the forefront. In order to understand the controversy of the stem cells it is important to first understand the whys and hows of this field of medicine. The analysis of stem cells and the controversy related to them are discussed in this website. To begin with, it is important to understand the stem cells. The stem cells are cells that can segregate into diverse kinds of cells. They can also be referred to as cells which have not yet reached their potential. They can be manipulated in order to become whatever including cells for vital organs such as heart or liver. This is seen in an example of a reproductive process that sees a combination of sperm and an egg to form a zygote and later forms an entire organism. The gene differentiation controls this process.
The stem cells will come from two main categories. The main category is the embryonic stem which is pulled from 3 to 5-day old embryo. There is more concern on embryonic stem cells by the activists. They are more useful because they tend to be harder and can form a wider variety of tissues. From a specific patient, the second category of stem cells that is the adult stem cells can be obtained from his or her bone marrow or fatty tissues. They are usually limited in number and the ability to change into different types of tissues.
The researchers consider these cells as important as they conform regenerative medicine. When 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. The researchers find these cells important as they form a valuable tool for research. These cells are important in completely revolutionizing the modern medicine and research.
The sourcing of embryonic stem cells forms the major controversy as discussed in this page. It is considered an ethical issue by many people as they originated from human embryos. This field of science is receiving battles from the religion which is receiving 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.
There are varied counterpoints that can be used against the controversy as explained 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. There are many clinics offering stem cell treatments for many illnesses that have no known treatment which is beneficial. The future of the stem cell is likely to be realized if there is a potential of iPSC technology.
