The first thing to know about stem cells is what they are; a stem cell is a cell that’s main purpose is the repairing of gone or mutilated cells in every area of the body. Stem cells have no specific purpose in other words they’re basically “blank” cells and can morph into any other type of cells within the body if necessary; dividing and repairing without end. When a stem cell multiplies the advanced cell that forms will carry on as a stem cell or take the form of a particular tissue elsewhere in the body. There are three varieties of stem cells:
- Totipotent Stem cell- a fertilized egg that functions as the structural support of every other cell in the body.
- Multipotent Stem Cell-can be used to generate several various types of cells inside the body.
- Pluripotent Stem Cells-with the exception of embryonic cells can be used to create any type of cell.
Therapy with Stem Cells
Stem cell research began somewhere in the mid 1800s when scientists made the discovery that particular cells inside the body were able to develop into other cells. The research done of the stem cells led to therapy treatments where stem cells are infused to lifeless or damaged area(s) and used to generate new, uninjured tissues to mend that area of the body. Stem cell treatment includes:
- Bone Marrow Transplants
- Therapy for Parkinson’s through use of stem cells
- Therapy for Alzheimer’s disease through use of stemm cells
The stem cells regenerative ability make this type of therapy an encouraging treatment for all kinds of degenerative diseases and research shows that it holds the answer to slowing down or stopping the aging process leading to the belief that further research will lead to a cure for all disease.
Pro’s and Con’s
Stem cell research and stem cell therapy has it’s pro’s such as the regeneration of all areas of the body repairing tissue that’s diseased or damaged and curing degenerative diseases i.e. Alzheimer’s disease. Those Pro stem cell research believe that the research and use of stem cells will lead to progression and medical findings that will aid us in living extended, healthier lives. Most of the controversy revolves around embryonic stem cell research. Weighing in on the pro side of embryonic stem cell research include the fact that they’re the only totipotent stem cells and can adapt into any sort of cell inside the adult body creating a limitless potential of healing disease. The controversy swirling arounf embryonic stem cell bouls down to whether or not a human life is lost in the process when embryonic cells are removed. Some believe it’s an ethics issue because in order to use embryonic cells for research the embryo must be destroyed. Current Embryonic stem cells aren’t conceived within the womb instead the eggs are fertilized in a laboratory environment.
