Has there ever been a head transplant in any animal?  Will there be some in humans in the future?

I did it with gummy bears once and IT WORKED!  Next step is humans.

Assuming you're talking about a human being; but should be applicable to all animals containing such organs:\n\nFor existence in general; the heart, as the body can 'live' without a functioning brain or liver for a while.\n\nThen the liver, since eventually the body would poison itself.\n\nThen the brain.\n\nHowever, if you're talking about complete 'removal', you need to define the brain. Are you speaking of the cerebral cortex alone or the whole thing? In the latter case, the heart and brain are equivelent since the lower brain stem controls heart rate (as well as other vital; functions,) and without either, neither would function and the body would die within minutes.

I know this is really gross but... are there any animals?\n\nlol lol just wondering (to save the human race)

Absolutely, I suggest\n\nYang X, Tian XC, (2002). Cloning adult animals - what is the genetic age of the clones? Cloning, 2(3):123-8. \n\nThat is an almost perfect review!\n\n:-) Happy reading!

Every day more and newer methods are developed for hair transplants.\nSee a doctor affiliated with a teaching institution to get the latest information

I think that face transplants are a wonderful breakthrough!  For far too long, people have had to live with horrible facial disfigurements and the stares that come with that because plastic surgery could only do so much.  Now, there is this wonderful procedure out there!  I'm so excited to see face transplants becoming a reality for so many people. :)\n\nEdited to add:  I'd like to comment that face transplants are NOT cosmetic surgery available to everyone.  You can't just get your face replaced with someone else's because you don't like yours.  Like an organ transplant, face transplants would be based on need -- not vanity.  We're talking about disfigured people or people with facial birth defects that can't be corrected via cosmetic surgery -- not people who just don't like their face.

Anyone who's ever had an organ transplant is "a creature made of sets of cells containing different DNA".\n\nIt's not impossible that you could graft or grow bits belonging to different animals into one single body, but it would take some advances in molecular biology to do it. You can't just snip the "genes for a head" from a lion and the "genes for a tail" from a snake, it's much more complicated than that.\n\nThat said, a mouse was grown a few years back that had a fully grown human ear on its back. It was supposed to indicate that replacement organs could be grown for people.

Human may survive for short period with an animal heart implanted on them. The immune systems organ rejection reaction would be the main problem in such situation which will be result to systems failure and will eventually lead to death. \n\nSuch thing you are referring to is called xenotransplantation  which is the transplantation of cells, tissues or organs from one species to another.  Immune rejection remains the biggest challenge for xenotransplantation.\n\nRead this excerpt from wikipedia:\n"The first cross-species heart transplant was performed in 1964, in which a 68-year-old man received a chimpanzee heart. He survived only two hours. Several other attempts have been made to transplant primate hearts into humans, with no patients surviving more than twenty-one days."☺

I think a great deal more needs to be done in animal cloning before humans get involved. Besides the ethical issues, there are real physiological difficulties that seem to erupt in cloned organisms. It seems that having two sets of genetic material really is important.

YES.Since the brain is essentially a storage facility for ones experiences through the five senses and able to triage information (much like an emergency room nurse determines which cases are most urgent and which ones can wait), a transplant without the memories coming along for the ride would make very little sense. Emotions are an integral part of our memory too.  I can't\n imagine that being lost in the transfer.  What do you think the fate of the brain removed will be?  The donor will be the recipient as well.  Dig it.

No.\n\nThere are several reasons. First, most "animal characteristics" are not the result of a single gene. Instead, they require many genes products working together with each other and the rest of the body. This is a level of complexity we simply don't understand yet.\n\nAnother major issue is getting the DNA into a person. People are beginning to experiment with modified viruses (ie, cannot replicate) for this purpose, but so far nothing has worked very well. Probably the biggest obstacle to gene therapy is a workable way to get new DNA into a person's cells.\n\nIn simpler organisms the DNA modifications have been done directly with fertilized eggs. That's a simple thing to do with plants and fruitflies, but a very difficult thing (not to mention the ethics involved) to do with people.\n\nWhile we are very able to insert particular genes into some cells, don't look for animal characteristics in the foreseeable future.

I would guess that it would be in the field of biochemistry. Perhaps cloning will be the next big thing, where we may be able to growth individual organs for transplants.

are you talking about human to human transplants or human to machine transplants?  an automaton w/ a human brain could, in theory, keep that human alive forever...disrupting the natural balance.  Human to human could be a chance to realy discover how the brain thinks.  We (inside a new body) will be able to see the world from a new perspective (literaly).

No one knows for sure. It's a personal opinion. Mine? Unfortunately they go nowhere. Although I believe reincarnation may be possible.

Man will never be able to create a human.God won't allow it.They may be able to cure diseases using stem cells to create new functioning organs and that would be  a blessing.

There have not been any studies utilizing transplantation of spinal cord tissue to cure or even ameliorate spinal cord injury. There however, have been a number of recent studies that have begun to show promise in possibly treating some of the effects of traumatic spinal cord injury. Experiments in rats and mice have recently been done that have led to some functional recovery of motor function after trauma to the spinal cord. The use of new medicines and other therapies in human spinal cord injury patients has also increased the function of people who have suffered these devastating injuries.

Yes, DNA manipulation in post-natal humans, Has Already Been Done, With Some Success, Consider BMT (Bone Marrow Transplant).
