It is starting. The end of keeping enormous amounts of livestock in a brutal way is coming to an end. The only thing they need to do is to give the muscle cells small electric shocks. Meat tastes best if it is an animal that has been able to run around, growing bigger muscles because of exercises. What needs to be done is while growing these muscle tissues, is let these muscle tissues "work out" . The best way would be to build some rudimentary nerve system that can be used to make the muscle twitch and relax. This does mean that two muscle structures must be build that are antagonist in movement. Like for example the muscles in the legs. The reason muscles become soft is because they are not used. Can you imagine eating a healthy piece of meat everyday without killing whole animals ?
Nowadays we use every part, like the skin. It will not be long until we can replicate perfect leather from artificially grown skin. We can even enhance the skin to give the leather certain abilities. And the best part is that we do not have to kill animals for food or for the skin. Which is a good thing. We do it because we have to. If the need to eat or clothe can be solved another way, that's good for humanity. and i am not even talking about a very high efficiency. No longer grow an entire animal, just the part we eat. And healthier food means a healthier life...

while they admit they haven't gotten the texture quite right (the lab-grown meat has the consistency and feel of scallop), they say the technology promises to have widespread implications for our food supply.
"If we took the stem cells from one pig and multiplied it by a factor of a million, we would need one million fewer pigs to get the same amount of meat," said Mark Post, a biologist at Maastricht University involved in the In-vitro Meat Consortium, a network of publicly funded Dutch research institutions that is carrying out the experiments.
Several other groups in the U.S., Scandinavia and Japan are also researching ways to make meat in the laboratory, but the Dutch project is the most advanced, said Jason Matheny, who has studied alternatives to conventional meat at the Johns Hopkins Bloomberg School of Public Health in Baltimore and is not involved in the Dutch research.
In the U.S., similar research was funded by NASA, which hoped astronauts would be able to grow their own meat in space. But after growing disappointingly thin sheets of tissue, NASA gave up and decided it would be better for its astronauts to simply eat vegetarian.
To make pork in the lab, Post and colleagues isolate stem cells from pigs' muscle cells. They then put those cells into a nutrient-based soup that helps the cells replicate to the desired number.
So far the scientists have only succeeded in creating strips of meat about 1 centimeter (a half inch) long; to make a small pork chop, Post estimates it would take about 30 days of cell replication in the lab.
There are tantalizing health possibilities in the technology.
Fish stem cells could be used to produce healthy omega 3 fatty acids, which could be mixed with the lab-produced pork instead of the usual artery-clogging fats found in livestock meat.
