People usually have 2 kidneys 2 lungs 2 eyes 2 breasts a bicameral brain so maybe a living human volunteer wants to grow a second pancreas to save a loved ones life ?...our species has the right to know what experiments go on AND RIGHTS TO KNOW DANGERS of GMOs nukes chemicals and WMD stockpiles ANYWHERE

I read all the article. To me the goal is noble : provide organs that can be transplanted to humans. They say waiting lists are long... The team proceeds slowly and carefully. The objective isn't to create monters...

I qyestion the whole field, from test tube babies,to the latest genetics of growing organs for transplant.
I question the whole field as 'is it necessary? As a race, at least in the affluent west, we are unable to accept that some people will not breed and that we all diel some very young, some prematurely, most old and knackered buut kept breathing, as opposed to living, by medical science.
There is no shortage of humans on the planet.

I just don't see a problem here. I think if a person worries about animal cruelty we should focus more on the great number of animals going extinct every day, about factory farms, about loss of habitat. Is it all right to raise an animal only for the sake of butchering it but wrong to raise one to save a human life or to save a person from suffering.

Could save many lives

I wonder if the human cells have to come from the person who needs the organ...I imagine that there would still be an issue with transplant rejection otherwise...

Interesting to see if human organs grown in animals would complicate transplants even more with not only rejection but also infection, autoimmune issues, etc. of both the animal and the human...

Research like this does not necessarily end in a final use...but can open more doors of possibility...

always amazes me: at a few weeks human embryos are almost undistinguishable from tadpoles or even fish embryos.
