Recently scientists discovered that a patient could recover, and his or her function can be restored after suffering stroke for a longer period. For this to happen, stem cells in his or her brain have to be stimulated.
Some scientists from UC-Irvine discovered that Transforming Growth Factor-Alpha often abbreviated as TGFa can activated adult stem cells that are in the affected area of the brain to differentiate, move through the brain and last bit not least, repair the damage caused by the stroke.
To prove this can happen, scientists tested a rat that was affected. The Transforming Growth Factor-alpha protein was then injected directly into its brain four weeks after the stroke damage. The recovery was 99%.
Darius Gleason who is a graduate student who was also working on the project mentioned that it is becoming clear that brain isn’t different from any other organ. We just assume that it is somehow superior given to what it can do. The brain is, without a doubt, the organ that decides what the body should do and what it shouldn’t.
Unlike many other organs, a damaged brain is more devastating, in fact, it means the end of your functioning as a human being. However, the latest findings have shown that the brain can indeed repair itself just like any other organ in the body if the stem cells are introduced into it.
A new study recently published that nasal administration of the Transforming Growth Factor-alpha can result in a recovery by 70%. The nasal passage is one of the non-invasive routs that is quite useful for this kind of therapy.
In the previous years, researchers from Germany proved that administering adult stem cells through the nose was one of the most effective methods. The new finding is proof that using a stimulating factor can also work best to stimulate differentiation of adult stem cells that are already there.
However, there are several trials still going on in Houston that involves infecting the stem cells into the bone marrow of the patients and their circulatory system. The cells have been seen to move to the area of the brain that is affected and immediately they reach there; they activate the repair process. There are still findings not yet confirmed; the existing results are more promising especially for future stroke patients.
The bottom line
A lot is going on in the stem cell world. The discovery of stem cells has opened the eyes of scientist to another level of medicine. Unlike the past, there is a hope that diseases such as cancer that were not curable in the past can now be cured. And now that it can work on the brain to restore functioning after stroke, it is becoming clear that it holds answers to many other fatal complications.
