This is a correction of the mention of artificial fetal brain tissue transplants in my 6/22/97 posting describing the Zichron Yaakov PD vacation seminar. My wife Aliza and I attended another lecture by Dr Rabai last night in Tel Aviv.I asked him for a clarification of the artificial fetal transplant research he referred to in Zichron Yaakov. It turns ou that he was referring to the growing of nerve cells from the healthy brain of an embryo and then using this tissue for brain tissue transplants.Thus the issue of requiring up to eight embryos from aborted fetuses could be avoided.He was not referring to in vitro fertilization procedures which would require growing the embryo in the womb of a surrogate and then extracting it. I neglected to ask him where this research is taking place. Does anyone have any information on the growing of brain nerve cells from brain tissue extracted from embryos?
