The Analysis of Stem Cells.
The medical technology has put research on stem cells at the forefront. There is the need for understanding the whys and hows of stem cells in order to be able to understand the controversy of this field of medicine. In this website, the review of the stem cells and their controversy related to them are discussed. On the first point, it is crucial to understand the cells. These are cells that can differentiate into different kinds of cells. These sales have not yet reached their potential. These cells can be used in to 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. One of the main categories is the embryonic stem cell pulled from 3 to 5-day old embryo. There is more concern on embryonic stem cells by the activists. The current research makes use of embryonic stem cells because they tend to be harder and can form a wider variety of tissues. There are adult stem cells that can be obtained from the bone marrow and fatty tissues of a specific patient. These type of cells are usually limited in their ability to change into the different types of tissues as well as number.
These cells are important as they are able to form a regenerative medicine. If 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. One of the importance is being able to completely revolutionize the modern research and medicine.
The sourcing of embryonic stem cells forms the major controversy as discussed in this page. This controversy is about ethical issues since the cells 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. The extraction of embryonic stem cells is regarded as destructive as an embryo has to be destroyed in order to obtain the cell which forms the basis of major controversy.
There are valid counterpoints used against the controversy as discussed here. It is estimated that around that 33% of zygote do not bond with uterine wall hence destruction of many embryos 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. There are hopes of growth of stem cell research in the future if the iPSC technology is realized.
