Adult stem cells
Adult stem cells have actually been used for decades for bone marrow
transplants, but more were used to treat other debilitating and fatal
diseases. Scientists hope that by getting control of this process
of differentiation within the laboratory, adult
stem cells can become a good therapeutic source that can be use
to treat some of the most common but serious diseases.
ADS were present in many tissues, but their numbers are quite small.
It is suggested by scientists that stem cells remain in a particular
area of a tissue for years without dividing, unless triggered by disease
or tissue damage.
Skin, bone marrow, blood vessels, brain, liver and skeletal muscle are adult tissues that contain stem cells, according to studies.
Scientists ask whether ADS are still originally derived from embryonic stem cells or other source is involved. So far, most have been examined in humans and few from animals.
ADS have the potential to replace a person of trillions of specialized
cells from few unspecialized cells. The idea of adult stem cell therapy
is to control and guide the growth of adult stem cells in a laboratory
and then use them to replace dysfunctional cells that are present
in the disease.
Some of the possible treatments involve in the replacement of cells in the brains are people with Parkinson's disease. It is also hoped that adult stem cells can repair heart damage, along with the goal of developing insulin-producing cells for diabetes.
ADS are present in small quantities and this present difficulties
in identifying and isolating them in large enough numbers for medical
Adult stem cells' self-renewal is not as successful as embryonic stem cells and they do not proliferate in the same degree. They also contain more DNA abnormalities as it age because as compared to 'young' embryonic stem cells, ADS are well, 'adult'.
