I recently received an email from Summit for Stem Cell Foundation which contained a great summary of legitimate stem cell research to combat Parkinson's Disease throughout the world. Here it is:
Roger Barker, United Kingdom. (2018 – ongoing.)
Fetal tissue transplants for Parkinson’s disease.
9 patients have received the transplants. Status unknown.
Jun Takahashi, Japan. (Sept. 2018 – ongoing.)
Allogeneic pluripotent stem cell-derived dopamine neuron transplant for Parkinson’s disease.
2 patients have received the cells. Both patients are doing well.
Malin Parmer, Sweden.
Embryonic stem cell-derived dopamine neuron transplant for Parkinson’s disease.
No patients have received any cells at this time.
Lorenz Studer, (NY) United States.
Embryonic stem cell-derived dopamine neuron transplant for Parkinson’s disease. Initializing a similar project using iPSCs.
No patients have received any cells at this time.
Jeanne Loring, (CA) United States.
Autologous iPSC-derived dopamine neuron transplant for Parkinson’s disease.
No patients have received any cells at this time.
Clinical Trials pending: Due to the COVID-19 pandemic we cannot speculate on when clinical trials will commence. As of Feb. 2020, clinical trials were anticipated to begin sometime in 2021.
Do you think embryonic stem cell research is unethical?
