They make all drug companies test their drugs on animals before they get to people. So why don't they try to figure out this whole stem cell research by using animals. It seems people would be more on board if they could say: "Hey, we broke this rat, monkey, hamster's back and fixed it with stem cells, now we think we can do it on people". Instead they want to mutilate human stem cells without really being sure they can do anything with them.

Ummm... they DO. As a matter of fact, a recent research study did exactly as you described -- a rat's own stem cells repaired neural damage to its severed spinal chord and it was able to hobble around. Not a perfect fix, but it was proof-of-concept. Human trials are much trickier because we obviously value human quality of life much more than a rat's or monkey's, and so even with a proven technique in animals, it will require decades of experimentation before it will be approved for use in humans.

As stated in the other posts, animals are used for stem cell tests, but to conduct specifically human stem cell tests, you must use human stem cells and human subjects, as only a human stem cell is completely, well... human - the DNA in it is human, not chimpanzee, or gorilla DNA. There are differences in the DNA sequences of all animals, which is what makes them different from each other. The animal stem cell studies are used to conduct experiments that would not be ethical to perform on live human subjects to see what experiments or therapeutic applications might come as a result of the results of an experiment. With this information the direction of promising research advancements in humans will be more clearly understood.

Furthrmore, most people are on board. In the US, 80% of people support increased federal funding for stem cell research. The House of Representatives, and the Senate just passed a bill granting additional funding, however Bush is threatening to veto it. Talk about ignoring the will of the people.

They do!!!! And have been doing it. Animal physiology is different than that of humans. Our bodies react differently to different things than those of animals.
On the news the other night, they had a rat that was paralyzed. They injected the rat with stem cells and eventually the rat was walking again.

With glyconutrient technology, stem cell production is enhanced.
That is a natural function.

i'm assuming your asking this question considering the fact which you think of its incorrect or merciless to do examine on animals whether i might desire to be incorrect. to answer your question, there is not any different effective option as of now. interior the destiny, we are able to enhance notebook fashions that mimic the human physique, yet it extremely is an prolonged techniques off. we desire animals to base something off of to get an thought of the way it extremely is going to impression us. in any different case, without animal examine, we would might desire to attempt quickly on people which could be relatively volatile. as an occasion, whilst somebody develops a sparkling drug, we would desire to make certain the way it reacts. by capacity of using an animal that has an analogous physique shape as us, we can get an thought of the way it would desire to react in us. it would be unethical for somebody to attempt a drug on people without understanding at all the threat of it killing you. you will possibly be able to think of it extremely is unethical to do an analogous for animals, or non-people. nicely i will assure you, whether it may look that way or look merciless, it extremely is for a good reason. it extremely is in comparison to we are being merciless to animals for no reason. if reality learn, animal examine saves lives. whether in a proper worldwide we would desire to no longer, we've not got the different concepts.

They HAVE to be able to do SOMETHING w/o harming humans.
I'd much rather them test on animals than humans (sorry PETA people).

What makes you think that they haven't?
