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 … Read More..Read More →
