Understanding the Stem Cells.
The forefront of medical technology is the research on stem cells. 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. To begin with, it is important to understand the stem cells. These are cells that can differentiate into different kinds of 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.
There are two main categories from which the stem cells are obtained from. The embryonic stem cell is one main category 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. There are adult stem cells that can be obtained from the bone marrow and fatty tissues of a specific patient. They are usually limited in number and the ability to change into different types of tissues.
The stem cells are important 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 forms a brighter future where scarred and damaged 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 major controversy in stem cell research is based on the sourcing of embryonic stem cells as discussed in this page. Many people regard this as a controversy as the embryonic stem cells originated from human embryos. This science research is receiving battles from the religion hands receiving a discourse in modern politics. There is different opinion raised by different people regarding the usefulness of adult stem cells modification rather than using the embryonic stem cells. There is also a controversy regarding the techniques used for current extraction of embryonic stem regarded as destructive.
The valid counterpoints used against this controversy are 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. 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.
