The Problem Of Stem Cells Essay

799 Words 4 Pages
For decades, researchers have been studying stem cells in order to find new ways for treating health problems. Stem cells are immature cells that have the potential to become different types of cells throughout the body; they can be divided and become differentiated. Because of this function, they can give rise to any tissue found in the body, they provide nearly limitless potential for scientific research. There are two types of stem cells: embryonic stem cells, and adult stem cells, which are found in adult tissues. Embryonic stem cells are found in a developing embryo, these stem cells can become any type of cell in the body. Adult stem cells are stem cells that reside in the already developed tissue; they act as a repair system for the body, replenishing cells, but also maintain the normal turnover of blood, skin, and intestinal tissues. Current studies show how stem cells are used to prevent or cure diseases and injuries, such as Parkinson’s disease, type 1 diabetes, heart disease, spinal cord injury, vision and hearing loss, and strokes. In the human body, there are more than 220 cell types, all of which come from embryonic stem cells. Stem cells have the ability to repair almost any part of the human body, and a second ability is that under the right circumstances, they can produce themselves indefinitely. Since stem cells can mass produce themselves in unlimited numbers, they can become any of the 220 cell types, and can be used in stem cell therapy and medical…
