Detailed explanation-1: -These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.
Detailed explanation-2: -Stem cells provide new cells for the body as it grows, and replace specialised cells that are damaged or lost. They have two unique properties that enable them to do this: They can divide over and over again to produce new cells. As they divide, they can change into the other types of cell that make up the body.
Detailed explanation-3: -Why are stem cells important? Stem cells are the body’s “master cells.” They are the building blocks of all organs, tissues, blood and the immune system. In many tissues they serve as an internal repair system, regenerating to replace lost or damaged cells for the life of a person.
Detailed explanation-4: -Stem cells are divided into 2 main forms. They are embryonic stem cells and adult stem cells. Embryonic stem cells. The embryonic stem cells used in research today come from unused embryos.
Detailed explanation-5: -Answer: Stem cells represent an exciting area in medicine because of their potential to regenerate and repair damaged tissue. Some current therapies, such as bone marrow transplantation, already make use of stem cells and their potential for regeneration of damaged tissues.
