Japanese scientists grow teeth from single cells. Is it promising for humans?

genetic research and staminal cells research is really on fashion today...many researchers work with staminal cells today...these cells can differentiate into any kind of organ under the control of proper growing factors..this is what we do in the laboratory...the problem is that it is difficult to use what we can see in our laboratory in animals and then in human..it is such a challenge and it implies years of further study because an animal is much more complicated than a cell and a human being is even more complicated than an animal like rats and mice we use in lab...this is the problem coming with this kind of news..you have to know that there is a great amount of work before each progress can be a good one for human being

This is very interesting. I actually just saw an article on yahoo about someone who had the tip of their finger grow back after he put some sort of powered that they derived from pigs. While this is all very interesting it is a little scary too.

i think this is one of the milestone in the development of science.if they can able to grow teeth from single cell then they can extend this for other parts of the body.Say eyes or liver or kidney and can save lot of people.The interesting factor here is they have developed it from primitive cell and not stem cell.very promising and prays for its success for other organs too.

It's marvelous what they can do these days .. a few years back they were able to grow ears on mice .. and yes I agree that's a hideous experiment to do on a living animal .. (I hate animal experiments too) .. and now teeth .. I think it won't be too long before they can regrow other organs, like livers, kidneys and hearts .. I hate the idea of animals being used in this way .. but applaud the scientists who are trying to discover ways to 'repair' human bodies .. I just wish they didn't have to use animals to prove their findings ..

The ultimate goal of regenerative therapy, however, is to develop fully functioning bioengineered organs that can replace lost or damaged organs after disease, injury or aging

Wow, this is pretty amazing news indeed! Hopefully it's the first step towards being able to reproduce bones and other things to help in the fight against diseases such as MS and Brittle Bone Disease. One can only hope. It definitely sounds promising, and I'll be following the news about this very closely. Thanks for bringing it to my attention.

A big step in medical science if it promises proper safety and efficacy for human beings..but what i think it has to go further studies for significant safety results.

i think it is simply fantastic this cpuld solve many problem . i hope this will start soon

this would be great to have for people like me that have or had soft teeth I have had false teeth since I was 23 my mom 38 nad my kids have them too

I WOULD LIKE IT!! We could grow our teeth like the sharks. One falls out, another grows instead of it. Cool! I hope by the time i will be an old witch without teeth it will be available for me too. LOL

I want to see a picture of the mousies with human teeth. :) I think it's great that scientists have been able to do this. Maybe someday people who've lost teeth will be able to actually grow them. And if not, at least their dentures could be made of real (non-used) teeth. :)

Yep, this is very promising for humans, IMO. In a few years from now, stem cells could be used to help our body regrow. For example, doctors could repair damaged mussles, skin, or even teeth. Dispite all the politics involed in stem cell research, I believe that stem cells will become the next "antibotics" of the century.

I haven't heard of this, but it sounds as though it could be the start of something big, although there's a long way to go yet. I wonder if this ever became an option to dentures, would it change the views some people have of stem cell research.

Oh that is so fantastic. To be able to have a full mouth with out metal. I hope it is successful, and soon released.

Oh..i haven't heard anything about this and this is news for me.Anyhow, if it is true also it is just the begining and it will take some time before we get to know the plus and negative points of this isn't it? for now, it looks promising and might be usefulll for many peopel isn't it?

sound scarry.... I hate clonning systems....:(

that is a good news!now we won't worry at all of having all our teeth extracted by the dentist. we can always replace our lost teeth. it is indeed very promising and helpful for humans. thank you for sharing this information to us.

Again, the Japanese did it! I always think they are brilliant people and I am right in that regard. I'd like to have better teeth, the ones I have are small. I want bigger teeth and bite bigger steak hehe
