Actually most vegetarians refuse meat out of belief a that animals are sentient being too .
P.S: The plant/animal cell argument if extended further would endorse cannibalism too.
would vegetarians be prepared to eat meat that is grown in a lab ? I bet my ass they wouldn't.
World's first lab-grown burger is eaten in London
The world's first lab-grown burger has been cooked and eaten at a news conference in London.
Scientists took cells from a cow and, at an institute in the Netherlands, turned them into strips of muscle that they combined to make a patty.
One food expert said it was "close to meat, but not that juicy" and another said it tasted like a real burger.
Researchers say the technology could be a sustainable way of meeting what they say is a growing demand for meat.
The burger was cooked by chef Richard McGeown, from Cornwall, and tasted by food critics Hanni Ruetzler and Josh Schonwald.
Upon tasting the burger, Austrian food researcher Ms Ruetzler said: "I was expecting the texture to be more soft... there is quite some intense taste; it's close to meat, but it's not that juicy. The consistency is perfect, but I miss salt and pepper.
"This is meat to me. It's not falling apart."
Food writer Mr Schonwald said: "The mouthfeel is like meat. I miss the fat, there's a leanness to it, but the general bite feels like a hamburger.
"What was consistently different was flavour."
Prof Mark Post, of Maastricht University, the scientist behind the burger, remarked: "It's a very good start."
The professor said the meat was made up of tens of billions of lab-grown cells. Asked when lab-grown burgers would reach the market, he said: "I think it will take a while. This is just to show we can do it."
Sergey Brin, co-founder of Google, has been revealed as the project's mystery backer. He funded the £215,000 ($330,000) research.
Prof Tara Garnett, head of the Food Policy Research Network at Oxford University, said decision-makers needed to look beyond technological solutions.
"We have a situation where 1.4 billion people in the world are overweight and obese, and at the same time one billion people worldwide go to bed hungry," she said.
"That's just weird and unacceptable. The solutions don't just lie with producing more food but changing the systems of supply and access and affordability, so not just more food but better food gets to the people who need it."
Stem cells are the body's "master cells", the templates from which specialised tissue such as nerve or skin cells develop.
Most institutes working in this area are trying to grow human tissue for transplantation to replace worn-out or diseased muscle, nerve cells or cartilage.
