Not likely. The whole focus of using genetically engineered cells to provide missing neurotransmitters, growth factors etc. is to get away from the use of fetal tissue as a source of these compounds. Of course this doesn't necessarily work in situations where discrete connections are required for repair. Currently, therapy for Parkinson's is focused on resupplying dopamine either through drugs, fetal tissue, engineered cells etc. Work on Alzheimers is also similarly based. The use of genetically engineered cells is a rapidly expanding field in the area of neuroscience and promises to be very exciting in the next few years.
