The initial wave of stem cell research has leaned more towards cloning and the concerns surrounding it. With much interest regarding this issue'' it helps to understand first what are stem cells and why medical science is aiming at further stem cell research in stretching the limits of disease control.
Basics
Stem cells have the potential to repair themselves by dividing to replace the broken cells. Through this capacity'' they can become another type of cell with more specific functions in the different body systems.
They are distinguished from other cells in your system through one significant trait. Stem cell research has shown that stem cells may yield millions of cells in a span of many months''as seen in laboratory tests. If the new yield can maintain their propertieswithout specialized functions as their parent stem cellsthen they may be further tested for long-term self renewal. The studies made to explore long-term self-renewal properties focused on two kinds of stem cells embryonic and somatic or adult stem cells.
Medical Advancements
Perhaps the most widely known result of stem cell research is gaining knowledge on how to isolate stem cells from human embryos. The embryonic stem cells derived for this process does not actually come from a female womb''as some may have feared. Embryos used for research are created through in vitro fertilization (IVF) processed from eggs donated for research.
One of the applications resulting from isolating embryonic stem cells is regenerating tissues possible for stem cell treatment. This type of therapy works to replace the damaged tissue with the regenerated cells from the parent stem cells. These genetic transplants may offer possibilities in producing replacement cells and tissues to treat some of today's serious ailments.
This is maybe why scientists clamor for more financial aid to fully explore stem cell research. With better findings''there can be hope for medical solutions to treating spinal cord injuriesstrokediabetesheart disease burns and Alzheimer's disease.
More Hope in Sight
It is notable how bone marrow transplants are seeing more success due to the blood-forming stem cells. This is perhaps the most plausible applications of stem cell technology''as doctors have been doing it for over 40 years. The newly transplanted cells aid in strengthening the immune system after leukemia lymphoma or other blood diseases are treated with sessions in chemotherapy.
The staggering potential of stem cells is instrumental for health and medical research. Further explorations into their inner composition would gain experts a better understanding of their specialized capabilities.
