Regulating Transfer and Use of Fetal Tissue in Transplantation Procedures: The Ethical Dimensions

Abstract

For twenty years scientists have worked to find an effective treatment to ease the quivering, the stiffness, and the difficulty in controlling bodily movements which are the primary symptoms of Parkinson's disease. The disease can be treated with L-dopa, a drug that mimics the dopamine that coordinates neural transmission in the human brain, which Parkinson's sufferers have ceased to produce in sufficient quantities. The L-dopa, however, produces damaging side-effects and sometimes proves ineffectual. Researchers discovered in animal experiments that the effects of a laboratory-developed disease simulating Parkinson's disease could be mitigated using fetal brain tissue transplants, which produced the natural dopamine the animals’ cells failed to produce adequately.These experiments were replicated with human subjects, and fetal tissue transplants have shown great potential as a treatment for Parkinson's disease. Fetal tissue is ideal for transplantation because it is in a stage of primitive development in which it adjusts easily to a new environment.
