Development of the Fetus
First Month (conception to 6 weeks)
Second Month (7-10 weeks)
Third Month (11-14 weeks)
Fourth Month (beginning of second trimester)
Fifth month (19- 22 weeks)

History
Fun Facts
* The History of Fetal Tissue Transplants
Parkinson’s Disease
* Parkinson’s Disease
Huntington’s Disease
What does it treat?
* Parkinson’s Disease
* Huntington’s Disease
* Retina Repair
* Future:
o Epilepsy
Biological Concepts
The Process: Cell Therapy Development in PD
* Parkinson’s Disease-
o Graft Efficiency has to be increased and variability reduced
+ Patient selection
+ Graft Placement
+ Composition and Preparation of the Graft Tissue
+ Developing immunological mechanisms
2 Years After Transplantation
The Process: Cell Therapy Development in PD
Evidence and Experiments
Society for Neuroscience-
* October 24, 1999- a study was presented at the Society for Neuroscience’s annual meeting, showing that the fetal cells can produce a critical neurotransmitter, reducing patient's tremors and paralysis. (Helmuth, 886)
Retina Repair-
o The procedure that Elisabeth Bryant, from the previous slide, underwent was retinal repair. Robert Aramant at the University of Louisville in Kentucky developed the transplant technique with Magdalene Seiler. (image on next slide)

Frontier Issues
Cost and Finances
* Surgery Alone- $43,500
* Pre-Operative Costs- $4,000
* Total- Approx.- $50,000
Controversy
Pro-life vs. Fetal Tissue Transplant Supporters
Ethical Issues
* It takes six fetuses to provide enough material to treat one Parkinson’s patient.
* Who is donating?
* Cell supply is limited.
* Better areas for transplantation?
Politics
