Explaining The Basics Of Stem Cell Treatment
February 20th, 2012Stem cells are described as biological cells that may divide and differentiate into specialized cell types and have a capability to recreate tissue throughout a lifetime. In adults, stem cells act as a restoration system for the human body. It is this exceptional ability of these stem cells which makes them useful in treating diseases.
The discovery of stem cell treatment is a medical breakthrough that can give hope to a great number of people around the world that are suffering from a range of illnesses. Researchers are convinced that stem cells present a great possibility in the remedy of diseases and injuries.
The treatment requires the utilization of intensive high-dose chemotherapy to eliminate cancerous cells. This stage, however, will usually destroy the healthy cells along with the cancerous ones, which is the reason new stem cells have to be transplanted into the bone marrow.
Stem cells have the function of generating blood cells. Consequently, they are able to repair and replenish what the chemotherapy eliminated. Barring difficulties, the transplanted stem cells should start creating normal ones and essentially “treat” the condition. For that reason, the procedure is occasionally also known as bone marrow transplant. Stem cells may be collected from the bone marrow, blood or blood from the umbilical cord of a new born baby.
Stem cell treatment has two classes: the autologous transplant and the allogenic transplant. The first one is the term for stem cells being obtained from a patient’s own body. The stem cells are collected while a patient is free of any symptom of sickness after chemotherapy.
Allogenic transplant, instead, makes use of stem cells extracted from somebody else. Most of the time, a close relative is selected as donor to improve greater likelihood of a close match. However, non-relatives can be donors if found matched to the patient.
Like any medical treatment, stem cell therapy has its own risks. Infection is the main danger as the patient’s body normally registers reduced immunity levels after contact with intense chemotherapy. During these times, a patient is at risk of getting life-threatening infections. Bleeding problems can also be suffered owing to low platelet levels. The use of intense chemotherapy may likewise have short-term and long-term side effects.
Even the source of stem cells might also subject the patient to additional dangers. If cells were not taken from the patient’s own body, there’s a tendency that the match isn’t going to be perfect. The donor cells could conflict with the patient’s own cells; this might cause serious trouble. But then again, many experts have seen that – provided the treatment was done correctly – transplanted stem cells do not usually fail to work effectively.
