But scientists caution that there’s no way to know when those stem cells will be ready because of their fragility and the difficulty in programming them to become the target dopamine-producing neurons. In the meantime, it’s important to continue with the fetal transplants that might allow patients longevity and improved quality of life. Because the fetal cells are already on the established path to becoming dopamine-producing cells, the body knows how to complete the process, stem-cell biologist and clinical trial member Malin Parmar told Nature. This is not the case will stem cells. However, Harvard stem cell researcher Ole Isacson noted that healthy fetal cells are not easy to get, either.
Another note of caution is the relative small number of patients who benefited from the treatments, a seeming handful in each of the clinical trials. These patients did remain medication and symptom free for more than a decade, but symptoms did eventually return. However, they all died from causes not related to the disease.
Discussion of the trial revival skirts the most controversial aspect of the transplants, use of aborted fetal tissue. Some opponents argue that this incentivizes women to chose abortion. That seems to be less of an issue in many of the European countries housing the new trial where access to abortion services is less controversial. But if these transplants are successful, many patients may need to soul search as they balance their future quality of life against moral reservations.
