Vat-grown meat, cultured in vats of nutrients from a single stem cell, could be on the market by 2009:

A single cell could theoretically produce enough meat to feed the world's population for a year. But the challenge lies in figuring out how to grow it on a large scale. Jason Matheny, a University of Maryland doctoral student and a director of New Harvest, a nonprofit organization that funds research on in vitro meat, believes the easiest way to create edible tissue is to grow "meat sheets," which are layers of animal muscle and fat cells stretched out over large flat sheets made of either edible or removable material. The meat can then be ground up or stacked or rolled to get a thicker cut.
"To produce the meat we eat now, 75 (percent) to 95 percent of what we feed an animal is lost because of metabolism and inedible structures like skeleton or neurological tissue," says Matheny. "With cultured meat, there's no body to support; you're only building the meat that eventually gets eaten."
Other than increased efficiency and the warm, fuzzy feeling of knowing that no beautiful creature must die for that flesh you so fancifully fry, there are other advantages, such as the possibility of tailoring the makeup of the meat to be healthier, or indeed to taste unlike any natural meat. Of course, making synthetic mincemeat is one thing, and making a steak is another:
Taste is another unknown variable. Real meat is more than just cells; it has blood vessels, connective tissue, fat, etc. To get a similar arrangement of cells, lab-grown meat will have to be exercised and stretched the way a real live animal's flesh would.
And then there is the question of whether the public would accept cultured meat; and indeed whether it would be acceptable for a vegetarian to eat something grown from a cell. And if it is, I wonder how long until fetishists start growing meat from their own cells for purposes of autocannibalism.

Researchers in the US have made advances in the production of cultured meat, i.e., meat grown in nutrients from cell colonies, but barriers, both technical and cultural, remain:

They envisage muscle cells growing on huge sheets that would be regularly stretched to exercise the cells as they grow. Once enough cells had grown, they would be scraped off and shaped into processed meat products such as chicken nuggets.
The idea of doing away with traditional livestock and growing steaks from scratch dates back at least 70 years. In a horizon-scanning essay from 1932, Winston Churchill said: "Fifty years hence we shall escape the absurdity of growing a whole chicken in order to eat the breast or wing by growing these parts separately under a suitable medium."
"Right now, it would be possible to produce something like spam at an incredibly high cost, but the know-how to grow something that has structure, such as a steak, is a long way off," said Mr Matheny.
"It won't appeal to someone who gave up meat because they think it's morally wrong to eat flesh or someone who doesn't want to eat anything unnatural," Ms Bennett [of the Vegetarian Society] added.
Of course, once it is possible to grow meat from donor cells without killing a living thing, a lot of things become possible. How long, I wonder, until some transgressive technogoth type decides to grow steaks from their own muscle cells and holds a cannibal dinner party? Despite the fact that no-one gets hurt, a lot of people would find this beyond the pale, and given how disgust often translates into legislation, chances are the practice will become outlawed in a great many countries. Which, of course, would only drive it underground and give it prestige and cachet.
