Stem Cell Research
A stem cell is essentially a “blank” cell, capable of becoming another more differentiated cell type in the body, such as a skin cell, a muscle cell, or a nerve cell. Microscopic in size, stem cells are big news in medical and science circles because they can be used to replace or even heal damaged tissues and cells in the body. They can serve as a built-in repair system for the human body, replenishing other cells as long as a person is still alive.
Adult stem cells are a “natural” solution. They naturally exist in our bodies, and they provide a natural repair mechanism for many tissues of our bodies. They belong in the microenvironment of an adult body, while embryonic stem cells belong in the microenvironment of the early embryo, not in an adult body, where they tend to cause tumors and immune system reactions.
Most importantly, adult stem cells have already been successfully used in human therapies for many years. As of this moment, no therapies in humans have ever been successfully carried out using embryonic stem cells. New therapies using adult type stem cells, on the other hand, are being developed all the time.
What are embryonic stem cells?
Each of us began life as an embryo. The early embryo (fertilized egg) is almost entirely made up of stem cells, which researchers want to extract for experiments in repairing and regenerating human tissues and organs. However, harvesting embryonic stems cells (usually obtained from so-called "spare embryos" created in fertility clinics) always involves the destruction of the human embryo. Laudable intentions do not justify immoral means.
