PATHOLOGY

Detailed explanation-1: -The organism in a stage between zygote to fetus is called an embryo* and the cells are called embryonic stem cells. At this point embryonic stem cells have the ability to become a cell for any part of the body (nerve, muscle, blood, etc.). This ability to become any type of cell in the body is called pluripotent.

Detailed explanation-2: -Stem cells are unspecialized cells of the human body. They are able to differentiate into any cell of an organism and have the ability of self-renewal. Stem cells exist both in embryos and adult cells.

Detailed explanation-3: -They are unspecialized, so they cannot do specific functions in the body. They have the potential to become specialized cells, such as muscle cells, blood cells, and brain cells.

Detailed explanation-4: -Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.

Detailed explanation-5: -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.
