The medical innovation of stem cell therapy has become one of the greatest milestones ever in the industry of medicine. Although this modern innovation has already made successful treatments to patients all over the world, there are still mysteries that enshroud it. The process of this therapy is quite simple to understand. The process by which this therapy is done is usually assisted by a machine which makes things a lot easier. In order to understand how it works, it is important to understand what stem cells are in the first place.
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. The most active stem cells in the body are the embryonic stem cells which are basically the cells that mostly make up the embryo. Researchers have already observed embryonic stem cells under the microscope but their full ability is still not fully understood. The use of embryonic stem cells is being done in many hospitals but it is still considered controversial to many medical researchers.
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. There are also recent discoveries about the abundance of adult stem cells in the human fats. 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.
Stem Cell Types
Stem cells are normally divided into three different types: the allogenic, xenogenic, and autologous stem cells. Stem cells that are harvested from animals are called the autologous stem cells. This kind of stem cell is usually used in transplants because it has the least chance of rejection. The term used to describe the stem cells that are used and harvested from the same species is allogenic stem cell. Stem cells do not usually have markers on them but when cells from the donor and patients are compatible, the results are outstanding. Xenogenic is a term used to describe stem cells that come from a distinct species to the receiver. Although there are cases that such stem cells are rejected by the receiver, there are still scenarios where they accepted by the body. If you want to know more about how stem cell therapy works, you should speak with your physician or research online.
