Stem cells are cells that are undifferentiated or also known as not being assigned to a specific functioning cell within the body. With having this characteristic, stem cells have the amazing potential to become many different cell types in the body during early life and growth. They have the capability to renew themselves through cell division and they can also be differentiated. When a stem cell divides, each new cell has a possibility to remain a stem cell or they can be induced to become a different type of cell with a specific function, such as a blood cell, a brain cell, or a muscle cell. (Mayo, Learn genetics Utah)
Embryonic stem cells (ESCs), as the name says, are derived from embryos that develop from eggs that have been fertilized in an in vitro fertilization clinic. Growing these cells in a lab give them the ability to continue dividing indefinitely, sustaining the ability to form the more than 200 adult cell types. With the cells having this potential to become such a variety of adult tissues they earn the title of being pluripotent stem cells, pluri meaning many and potent meaning potentials. In humans, these cells no longer exist after about five days of development. They are then donated for research reasons with informed consent of the donors. (NIH 2009, CIRM)
Another type of stem cell would an adult stem cell (ASC). They are known to be undifferentiated cells found among differentiated cells in a tissue or organ. The primary roles of an adult stem cell in a…
