Are You Ready for "Cultured Meat?"

South Carolina scientist works to grow meat in lab.
CHARLESTON, South Carolina (Reuters) – In a small laboratory on an upper floor of the basic science building at the Medical University of South Carolina, Vladimir Mironov, M.D., Ph.D., has been working for a decade to grow meat. A developmental biologist and tissue engineer, Dr. Mironov, 56, is one of only a few scientists worldwide involved in bioengineering "cultured" meat.
It's a product he believes could help solve future global food crises resulting from shrinking amounts of land available for growing meat the old-fashioned way ... on the hoof.
 Could it be worse than spam?
"It will be functional, natural, designed food," Mironov said. "How do you want it to taste? You want a little bit of fat, you want pork, you want lamb? We design exactly what you want. We can design texture. I believe we can do it without genes. But there is no evidence that if you add genes the quality of food will somehow suffer. Genetically modified food is already normal practice and nobody dies."

Dr. Mironov has taken myoblasts -- embryonic cells that develop into muscle tissue -- from turkey and bathed them in a nutrient bath of bovine serum on a scaffold made of chitosan (a common polymer found in nature) to grow animal skeletal muscle tissue. But how do you get that juicy, meaty quality?

Genovese said scientists want to add fat. And adding a vascular system so that interior cells can receive oxygen will enable the growth of steak, say, instead of just thin strips of muscle tissue.
 I can wait until they get it right.   In the meantime, I'll enjoy steaks from cows and bacon from pigs.
