An Education on 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. In this website, the review of the stem cells and their controversy related to them are discussed. To begin with, it is important to understand the stem cells. Simply, these are cells that can separate into, unlike cells. The stem cells are cells that have not yet reached the potential. They can be manipulated in order to become whatever including cells 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 is a process controlled by the gene differentiation.
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. The adult stem cells are usually limited in the ability to change into different types of tissues and their numbers.
The stem cells are important they are able to form a regenerative medicine. When injected and the right conditions are met, these cells are able to replace damaged, malignant tissue or scarred. This research will be important in forming a brighter future where damage 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 fueled by religion that battles science which is seeing a discourse in modern politics. Many people in the current times are raising opinion on the modification of adult stem cells rather than using embryonic stem cells. There is also a controversy regarding the techniques used for current extraction of embryonic stem regarded as destructive.
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. 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.
