What is Cell Medicine?
Stem cells are the master cells that develop into blood, brain, and all other body
tissues. These master cells have the ability to repair polanskyseed, restore, and replace tissue.
They have also been shown to have the potential to cure diseases, such as leukemia
and autoimmune disorders.
Embryonic stem cells, which are pluripotent (plur-em-pee-uh-tunt) cells, come from
the inner cell mass of a blastocyst, a small embryo that is about 3 to 5 days old.
These pluripotent stem cells can be reprogrammed by scientists to become a
different type of cell, such as a heart muscle cell or a nerve cell.
These stem cells can then be used to treat a wide range of conditions and diseases,
including spinal cord injuries and osteoarthritis. They can also be used to produce
new skin cells and other tissues.
There are two types of stem cells: embryonic stem cells and adult stem cells.
Embryonic stem cells are derived from the embryo, and can be reprogrammed to
make any type of cell in the human body.
Scientists have used these cells to successfully create a variety of cell types and
tissue in the laboratory, and have also tested them for use in people with disease.
This type of research is a major advance in the field of regenerative medicine, and
has opened the door to more promising treatments for diseases that have remained
untreatable.
Many of these cells are still being tested in clinical trials to evaluate their safety and
effectiveness. These trials include a number of tests to determine if the stem cells
are safe to be injected into people, and whether they can cause immune system
rejection.
Another way that scientists are testing their stem cells is by growing them in a
laboratory in a process called cell culture. The cells are grown in a sterile
environment under strict good manufacturing practices (GMP) standards. This
ensures that the cells are pure and have a consistent, repeatable appearance.
One way to increase the number of stem cells in a laboratory is by using a technique
called therapeutic cloning. In this process, a patient’s own bone marrow or blood
cells are removed and transferred to the lab where they are treated with a chemical
that helps them grow.
This process can increase the number of specialized stem cells by thousands or even
millions. These specialized cells can then be used to treat diseases, such as
Parkinson’s disease, which causes the specialized brain cells that stop uncontrolled
movement in people with the condition to be damaged.
In addition, these cells can be used to test drugs for their effects on nerve or heart
cells, or to screen drugs for toxic side effects. Several studies have demonstrated
the effectiveness of this method in generating a variety of cell types and tissues that
can be used to treat patients with neurodegenerative diseases, such as Parkinson’s
or Alzheimer’s.
Using adult stem cells in these clinical trials is still being evaluated, and researchers
hope that this research will lead to new therapies for patients with diseases that
have remained untreatable. Currently, doctors use adult stem cells in bone marrow
transplantation, which is a treatment that has helped thousands of people with
cancer and other blood or immune diseases. The most important use of adult stem
cells, however, is in regenerative medicine, where the stem cells are used to replace
or repair damaged tissues.
