1 Fetal Tissue Transplants Michelle Gomez

2 Words You May Need To Know  Definitions-  Fetal tissue transplants  Parkinson’s Disease (PD)  Huntington’s Disease (HD)  Dopamine (DA)

3 Development of the Fetus

4 First Month (conception to 6 weeks) Second Month (7-10 weeks) Third Month (11-14 weeks) Fourth Month (beginning of second trimester) Fifth month ( weeks)

5 Seventh Month (beginning of third trimester weeks) Sixth Months (23-26 weeks) Eighth month (31-34 weeks) Ninth month (35 weeks to delivery)

6 History

7 Fun Facts I. The History of Fetal Tissue Transplants A. The First Fetal Tissue Transplant in Sweden in Halifax The New England Journal B. Future Implementation 1. Huntington’s Disease (HD) 2. Epilepsy 3. Brain and Spinal chord injuries

8 Parkinson’s Disease II. Parkinson’s Disease A. What is it? James Parkinson B. Implementation- 1. “Studies with transplantation of human fetal mesencephalic tissue, rich in dopaminergic neurons, to the striatum in PD patients were started in 1987.” (Björklund, 382) C. Main Objectives- 1. Grafted dopaminergic neurons… 2. Patient’s brain… 3. Measurable clinical improvement…

9 Huntington’s Disease II. Huntington’s Disease: A. What is it? George Huntington B. Implementation- 1. “…the first pilot clinical trials of neural transplantation in patients commenced in 1990.” (Dunnett, 397) C. Main Objectives- 1. Collecting data… 2. Using comparable assessments…

10 What does it treat?  Parkinson’s Disease  Huntington’s Disease  Retina Repair  Future: Epilepsy

11 Biological Concepts

12 The Process: Cell Therapy Development in PD I. Parkinson’s Disease- A. Graft Efficiency has to be increased and variability reduced i. Patient selection ii. Graft Placement iii. Composition and Preparation of the Graft Tissue iv. Developing immunological mechanisms

13 2 Years After Transplantation

14 The Process: Cell Therapy Development in PD

15 Evidence and Experiments Society for Neuroscience-  October 24, 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- 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)

16 Retina Repair Fetal tissue inserted here

17 Frontier Issues

18 Cost and Finances  Surgery Alone- $43,500  Pre-Operative Costs- $4,000  Total- Approx.- $ 50,000

19 Controversy Pro-life vs. Fetal Tissue Transplant Supporters

20 Ethical Issues 1. It takes six fetuses to provide enough material to treat one Parkinson’s patient. 2. Who is donating? 3. Cell supply is limited. 4. Better areas for transplantation?

21 Politics  December  July 1991 and April  January 22, 1993-

22 Politics Who’s involved? President Bush President Reagan President Clinton President Bush (present)
