Understanding the Stem Cells.
The research on stem cells forms the forefront of medical technology. 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. On the first point, it is crucial to understand the cells. Simply, these are cells that can separate into, unlike 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. The example is this the zygote which is a combination of a sperm and an egg in the reproductive process to eventually become an entire organism. The gene differentiation controls this process.
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. The embryonic stem cells have more concerned from 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. 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 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 … Read More...
