Therapeutic cloning

Therapeutic cloning uses our own DNA to create stem cells.

When cells in our body die, they are replaced by stem cells. They come in different types and have different uses in our body. These cells duplicate and develop into "normal" cells.

Scientists hope that stem cells can be used for
 * Making new, healthy cells replacing sick cells or even entire organs
 * Testing medicines, instead of testing them on animals
 * Scientific research regarding for example development of cancer cells

Sometimes our body rejects transplantations of other stem cells, but therapeutic cloning uses our own DNA and creates stem cells that already exists in our body.
