Just like most cells, Stem Cells are unicellular, however they have two distinct properties that are completely different from other cells, shown through two unique qualities. They can replicate themselves continuously and they can grow into any of the body’s 220 different cell types. These two qualities makes Stem Cells promising tools in future medical research, which allows patients to receive needed cells or tissues, or have diseased cells or tissues replaced with healthy ones. Stem cells are primitive cells, meaning they have the capacity to divide and replicate indefinitely, or to form specific tissues or organs in the human body. In other words, there are 2 types of cells in the human body. Human Embryonic Stem cells (hES cells) were first discovered in 1998 by James A. Thomson and his team, and can only be collected from pre-implantation embryos, and have proven abilities to form cells of all tissues and organs in the human body. The other type of stem cells are ‘adult’ stem cells. ‘Adult’ stem cells are found in a wide range of tissues in the human body, including in the foetus and after birth. Both embryonic and ‘adult’ stem cells are distinctive by two definitive characteristics. Firstly, they are unspecialised cells, holding the capacity to form any type of tissue in the body, as long as they are designed to do so.

Embryonic stem cells were first discovered in Nineteen Eighty-Eight, and are known to be one of the most primitive types of cells. These types of…
