The Science Behind Stem Cell Therapy

One of the leading updates in the medical world is the discovery and success of stem cell therapy. Although there are still some controversies that imbed in the modern discovery, stem cell therapy has still continued to receive praise from those that have been treated by it. Stem cell therapy may be a new discovery but its execution is not really that complicated to fathom. The process by which this therapy is done is usually assisted by a machine which makes things a lot easier. It is necessary to understand the definition of stem cells first in order to know what happens in this therapy.

Stem Cells in the Body

A stem cell is basically a special type of cell in the human body that aids the regeneration of tissues in the system. An embryonic stem cell is one of the most active stem cells produced by the human body but it is only present in an embryo. Embryonic stem cells have very fast regenerative abilities but their full nature is still shrouded by mystery to researchers. Researchers have found out that these stem cells can successfully treat certain patients but their use is still considered controversial to most.

The stem cells that can be found other than embryos are called adult stem cells. Adult stem cells are found in almost all parts of the body, including liver, bones, and other tissues. The use of stem cell therapy is already legal in all places but their availability is still limited to certain regions in the country. Adult stem cells are typically acquired from the human brain tissues, bone marrow, and sometimes from the muscles. Researchers have also recently found out that fats contain large numbers of adult stem cells. The results of this stem cell treatment mainly depends on the source of the stem cells and how they are injected to the human body.

The Type of Stem Cells

Xenogenic, allogenic, and autologous are the three types of stem cells. Autologous stem cells are simply the stem cells that are gathered from animals. This kind of stem cell is usually used in transplants because it has the least chance of rejection. Allogenic stem cells are categorized as those that are harvested from the same species, in which case human to human. Therapies using this kind of stem cells are considered the safest due to the compatibility of stem cell markers. Xenogenic is a term used to describe stem cells that come from a distinct species to the receiver. You might think that xenogenic stem cells have less likelihood of survival than other types but they actually have high chances of acceptance to the host body. If you want to know more about how stem cell therapy works, you should speak with your physician or research online.
