Fetal tissue implant or fetal cell therapy is an experimental medical therapy where researchers implant tissue from a fetus into a person as treatment of a disease. In the case of Parkinson's disease, it is hoped that the fetal tissue would produce chemicals, specifically dopamine, which is lacking in the diseased brain. This therapy is also being investigated for treatment of Alzheimer's disease and Huntington's disease. Fetal tissue is unique since it is fast growing and has a lower possibility of rejection from the host's immune system than adult cells.
