STEM CELLS ARE unique cells in the body of many multicellular organisms that have the ability to develop and change into many different cells of the body. Stem cells have been studied in many animals including mice, monkeys, and humans and scientists have been able to unravel a great deal about their important properties.

Embryonic stem cells (as their name indicates) are found in embryos during very early stages of life and are responsible for the formation of different tissues of the body. Scientists have been able to manipulate the development of such cells in animals including monkeys and have made them convert into specific tissues that could potentially be used to treat different medical conditions.

Embryonic stem cells derived from monkeys have many similarities with human ...
