X-Message-Number: 3443 Date: Thu, 8 Dec 1994 14:25:46 -0500 (EST) From: Subject: SCI.CRYONICS Frozen animals and gene transference Date sent: 8-DEC-1994 14:18:21 Again the important issue to study animals that can survive frozen conditions is addressed. This time the practical application of such study cannot be denied. This technique is already used in medicine. I like to point out that one need not be young to have seed cells for storage. studies with animals cells have shown that any somatic cell's chromosomes can be divided and be used for fertilization. Age of the donor does not effect the integrity of the embryo and fetus. Apparently damage (if any) to the DNA is repaired after the somatic cell "divides". It is an ethical issue. Should, say a 90 year old, person pay someone to develop a fetus from his cells for the soul purpose of obtaining seed cells for rejuvenation or seed cells that had DNA transferred from animals that can survive the frozen state in order to make it possible for a human to produce chemicals to survive this state. The argument that these animals are not frozen to a low enough temperature to survive entropy for 200 or more years needer holds because these animals are able to repair damage that occur at that temperature. Hence no need for LN temperatures and the problems associated with it. Jan (John) Coetzee Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=3443
