The potential needs for stem cells have made it a highly available focus in medical articles today. Stem cells are the precursors to all cell in the human body, and are primarily produced in the bone marrow in adults. During times of crisis, such as when a patient suffers from leukemia, the spleen and other organs that contain stem cells during infant development will take over production. This is the body's way of preserve proper cell balances and replenishing itself as old cells die. For example, red blood cells in the circulation merely have a lifespan of approximately four months; during that time the hematopoietic stem cell in the bone marrow are continuously producing new rubriblasts, the precursor cells that will over time become mature erythrocytes.
Heart failure is a devastating blow to the human body system, and despite the best efforts of major hospitals and researchers often results in permanent organ damage and eventual death. Researchers are fighting to put a stop to the high mortality rate of congestive heart failure, and believe stem cells may be the way to do it.
There are many forms of stem cells; for the sake of following a line of investigation scientists they are currently focusing on the embryonic and adult varieties. Embryonic stem cells come from a blastocyst, a four to five day old human embryo. During gestation these pluripotent cells will displace and breed, forming the human body and internal organs of the fetus. Embryonic stem cell are highly valued for inquiries for some reasons; they are able to provide large numbers of replenishing cells and have no limitations on what form of cells they can become. The use of embryonic stem cells is highly polemical, however, due to the fact that collection often requires the destruction of the embryo.
Stems cells may also can be grown for the purpose of transplants.Ts to be had for an organ transplant are not as easily obtained as physicians would wish for, and there are often waiting lists years long for every available organ. Stem cells grow readily in a laboratory nature, and if unstimulated to differentiate will imitate pluripotent daughter cells. This results in a tissue that will in effect adapt to whatever environment it is placed in. Research scientists theorize that with the proper environment essentially grow heart tissue and transplant it to the patient who has suffered signs and symptoms of congestive heart failure, replacing the dead and damaged tissues with live, vital tissue. This procedure would allow the heart to function more easily and hopefully give the patient a better chance for survival.
There are respective methods that have been published in research journals regarding the application of stem cells in the remedy of signs and symptoms of congestive heart failure failure. Congestive heart failure results when cells in the heart are dysfunctional or destroyed and the heart is unable to properly pump blood all the way through the body. Several patients are able to be treated using mechanical aids or transfer, but this is not each time the case. Several years ago a assemblage of patients with no other to be had options for treatment agreed to be part of a test analyze regarding stem cells. Autologous stem cells were taken out from the marrow and injected into the failing heart tissue through the chest wall. Patients who acknowledged this treatment showed clear progress, presumptively as a outcome of stem cell action. The microscopic means by which this occurs is still unknown; however, research scientists anticipate that the stem cell is either growing new vessels or acting as a beacon to bring other cells in to repair the damaged tissue.
With current medicine the prognosis for sufferers of congestive heart failure is grim. At least fifty percent will die within five years of being diagnosed, and individuals who are not victims of this mortality rate will feel the effects of their heart failure for the rest of their lives. Stem cell research represents at least a chance for those patients to beat these odds. With anything that is good there is also evil but in my humble opinion after much research I feel that stem cell research should continue.
