Stem Cells Are Nature s Own Transformer - 1106 Words

Jonice Watts PLSS 200 – 01 Dr. Prakash December 4, 2014 Stem Cell Therapy Stem cells are nature’s own transformer. Stem cells have the extraordinary opportunity to develop into several different cell types in the body during early stages of life and development. Furthermore, in countless tissues they act as an internal repair system, dividing effectively without limit to replace other cells as long as the person or animal is still living. When a stem cell divides, each new cell has the chance to either stay a stem cell or become another type of cell with an additional specialized function, such as a red blood cell or a muscle cell. Stem cells are distinguished from other cell types by two important features. First, they are†¦show more content†¦Adult or somatic stem cells are found inside of different types of tissue. These specific stem cells have been found in tissues such as the liver, blood, blood vessels, skeletal muscles, skin, and the brain. They continue in a non-dividing or inactive state for many years until activated by a disease or tissue injury. Adult stem cells are able to divide or self-renew forever, enabling them to create a range of cell types from the introducing organ or even renew the entire original organ. However, it is commonly thought that adult stem cells are restricted in their ability to separate based on their tissue of origin, but there is some indication to recommend that they can decide to become other cell types. Embryonic stem cells are originated from a four or five day old human embryo that is in the blastocyst phase during development. The embryos are typically extras that have been generated in in vitro fertilization clinics where numerous eggs are fertilized in a test tube, but only one will be implanted into a woman. However, when removing embryonic stem cells, the blastocyst stage gesticulates when to isolate stem cells by placing the inner cell mass of the blastocyst into a culture dish enclosing a nutrient and rich broth. Requiring the essential stimulation to differentiate, they start to divide and replicate while preserving their power to become any cell type in the human body. Eventually, these undistinguishable cells can be encouraged to produce specialized
