Technology Ethic: Stem Cells

Stem Cell:

Stem cells can be thought of as blank slates or cells that have yet to become specialized. They can be transformed to become cells with special functions.

History/Background of Stem Cells:

In the mid 1960's, R. G. Edwards and colleagues at Cambridge University began studying differentiation of rabbit embryonic cells in an artificial environment. They manipulated these embryonic cells into specific types of form such as connective tissue and muscle neurons.

Richard Gardner, a graduate student of R. G. Edwards, had furthered the experiment with mice blastocoels. As a result, human blast cysts became available since R. G. Edwards' laboratory in the early 1980s.

In 1986, Peter

These cell lines were capable of prolonged and undifferentiated process. Yet, maintained the ability to develop into a variety of specific cell types, including neural, gut, muscle, bone and cartilage cells.

In theory, if stem cells can be grown, it would be possible to grow cells that has medical importance such as bone marrow, neural tissue, muscle tissue, or any other cells.

ES cells have the capacity to multiply indefinitely. They can give rise to new stem cells with the same potential and more specialized daughter cells. This unique property could allow the creation of tissue banks of both undifferentiated and specialized cells and tissues. Treatment of diseased and damaged tissue would involve transplanting new cells or tissue of the type affected by the particular disease. Such as inserting cardiac cells into the patient, in the case of heart disease.

Treating specific cell types by genetically enhancing them, it creates a shortcut which can be used to treat diseases that involve those specific cell types. It creates many new opportunities for cancer patients and can bring a new hope into their lives.

Adult Stem Cells:

AS cells are undifferentiated cells that are found in adult tissues. They can be replicated and become specialized cells of that particular tissue from which they originated.

The AS cells contain about 300 different specialized types of cells. Specific organ stem cells are the bone marrow, digestive
